Flammable liquids shall be stored, handled, and dispensed from approved containers.

Smoking shall be prohibited when handling or working around flammable liquids.

Clothing contaminated by flammable liquid shall be changed as soon as possible.

Open flame and other sources of ignition shall be avoided.

ELECTRICAL HAZARDS

All overhead and underground electrical conductors and all communication wires and cables shall be considered energized with potentially fatal voltages.

The employer shall certify that each employee has been trained to recognize and is appropriately qualified to work within proximity to electrical hazards that are applicable to the employee’s assignment.

Arborists and other workers shall be instructed that

(a)  electrical shock will occur when a person, by either direct contact or indirect

contact with an energized electrical conductor, energized tree limb, tool, equipment,           or other object, provides a path for the flow of electricity to a grounded object or

to the ground itself. Simultaneous contact with two energized conductors phase to phase will also cause electric shock that may result in serious or fatal injury.

(b)  electrical shock may occur as a result of ground fault when a person stands near

a grounded object (for example, if an uninsulated aerial device comes into contact with a conductor with outriggers down).

(c)  in the event of a downed energized electrical conductor or energized grounded

object, there exists the hazard of step potential.

If the minimum approach distance for a qualified line-clearance arborist or for a qualified arborist (see Table 1.) cannot be maintained during arboricultural operations, the electrical system owner/operator shall be advised and an electrical hazard abatement plan shall be implemented before any work is performed in proximity to energized electrical conductors.

Working in Proximity to Electrical Hazards

The items contained in the General Electrical section 2.1(previous) shall always be included in the review of this section.

An inspection shall be made by a qualified arborist to determine whether an electrical hazard exists before climbing, otherwise entering, or performing work in or on a tree.Only qualified line-clearance arborists or qualified line-clearance arborist trainees shall be assigned to work where an electrical hazard exists.  This currently is not in the scope of work that this company performs and is not under consideration.  Again, our arborists are not qualified for line-clearance and therefore must maintain a minimum approach distance as described below in Table 1.

The tie-in position should be above the work area and located in such away that a slip would swing the arborist away from any energized electrical conductor or other identified hazard.

While climbing, the arborist should climb on the side of the tree that is away from energized electrical conductors while maintaining the required distances shown in Table I.

Ladders, platforms, and aerial devices, including insulated aerial devices, shall be subject to minimum approach distances in accordance with Table 1 as applicable.

Aerial devices with attached equipment (such as chippers) brought into contact with energized electrical conductors shall be considered energized. Contact by people and/or equipment shall be avoided.

(c) support electric power tools and supply cords by a tool lanyard or separate line, as appropriate to the work, when used aloft.

Chain saws

When an arborist or other worker is working in a tree other than from an aerial device, chain saws weighing more than 15 pounds (6.8 kg) service weight shall be made safe against falling (i.e., supported by a separate line or tool lanyard).

Secure footing shall be maintained when starting the chain saw.

When starting a chain saw, the operator shall hold the saw firmly in place on the ground or otherwise support the saw in a manner that minimizes movement of the saw when pulling the starter handle. The chain saw shall be started with the chain brake engaged, on saws so equipped. Drop-starting a chain saw is prohibited.

Chain-saw engines shall be started and operated only when other arborists and workers are clear of the chain saw.

When operating a chain saw the arborist or other worker shall hold the saw firmly with both hands, keeping the thumb and fingers wrapped around the handle.

Arborists shall use a second point of attachment (for example, lanyard or double-crotched climbing line) when operating a chain saw in a tree, unless the employer demonstrates that a greater hazard is posed by using a second point of attachment while operating a chain saw in that particular situation. Using both ends of a two-in-one lanyard shall not be considered two points of attachment when using a chain saw.

Chain-saw mufflers and spark arresters (if the latter are provided) shall be maintained in good condition.

The chain brake shall be engaged, or the engine shut off, before setting a chain saw down.

When a chain saw is being carried more than two steps, the chain brake shall be engaged or the engine shut off. The chain saw shall be carried in a manner that will prevent operator contact with the cutting chain and the muffler.

The chain-saw operator shall be certain of footing before starting to cut. The chain saw shall not be used in a position or at a distance that could cause the operator to become off-balance, have insecure footing, or relinquish a firm grip on the saw.

Arborist saddles and lanyards used for work positioning shall not be altered in a manner that would compromise the integrity of the equipment.

Hardware used in the manufacture of arborist saddles shall meet the hardware material, strength, and testing requirements outlined in ANSI 359. l.

Arborist climbing lines shall have a minimum diameter of I/2 inch (12.7 mm) and be constructed from a synthetic fiber, with a minimum breaking strength of 5,400 pounds

(24.02 kilonewtons (kN)) when new. Maximum working elongation shall not exceed 7 percent at a load of 540 pounds (2.402 kN). Arborist climbing lines shall be identified by the manufacturer as suitable for tree climbing.

EXCEPTION

In arboricultural operations not subject to regulations that supersede Z133.1, a line

of not less than 7 /16 inch (11 mm) diameter may be used, provided the employer            can demonstrate it does not create a safety hazard for the arborist and the arborist      has been instructed in its use. The strength and elongation ratings of the line           selected shall meet or exceed that of 1/2-inch (12.7 mm) arborist climbing line.

Prusik loops, split-tails, and work-positioning lanyards used in a climbing system shall meet the minimum strength standards for arborist climbing lines.

Snap hooks (rope snaps) used in climbing shall be self-closing and self-locking, with a minimum tensile strength of 5,000 pounds (22.24 kN).

Carabiners used in climbing shall be self-closing and self-locking, with a minimum tensile strength of 5,000 pounds (22.24 kN). Carabiners shall be designed to release the load by requiring at least two consecutive, deliberate actions to prepare the gate for opening.

Splicing shall be done in accordance with cordage manufacturers’ specifications.

All load-bearing components of the climbing system shall meet the minimum standards for arborist climbing equipment.

Equipment used to secure an arborist in the tree or from an aerial lift shall not be used for anything other than its intended purpose.

EXCEPTION

The arborist climbing line may be used to raise and lower tools.

Rope ends shall be finished in a manner to prevent raveling.

Ropes and climbing equipment shall be stored and transported in such a manner to prevent damage through contact with sharp tools, cutting edges, gas, oil, or chemicals.

Arborist climbing lines shall nevel be left in trees unattended.

Arborists shall have available a climbing line and al least one other means of being secured while working aloft; for example, an arborist climbing line and a work-positioning Ianyard.

The arborist shall be secured while ascending the tree. The arborist shall be tied in once the work begins and shall be tied in until the work is completed and he or she has returned to the ground. The arborist shall be secured when repositioning the climbing line.

While ascending a ladder to gain access to a tree, the arborist shall not work from or leave the ladder until he or she is tied in or otherwise secured.

Hands and feet should be placed on separate limbs, if possible, and three points of contact should be maintained with the tree while climbing.

A false crotch and/or false crotch redirect may be used at the discretion of the arborist in

lieu of a natural crotch.

The tie-in position should be well above the work area so that the arborist will not be subjected to an uncontrolled pendulum swing in the event of a slip.

When a climber is working at heights greater than one-half the length of the arborist climbing line, a figure-8 knot shall be tied in the end of the arborist climbing line to prevent pulling the rope through the climbing hitch.

Pruning and Trimming

Communications among arborists aloft and among arborists and other workers on the ground shall be established before cutting and dropping limbs. The command “stand clear” from aloft and the response “all clear” from the ground are terms that may be used for this purpose. Pre-arranged, two-way hand signals may also be used. Arborists and other workers returning to the work area shall be acknowledged by arborists aloft.

Pole pruners and pole saws, when hung, shall be securely positioned to prevent dislodgment. Pole pruners or pole saws shall not be hung on electrical conductors or left in a tree unattended. Pole saws and pole pruners shall be hung so that sharp edges are away from the arborist and shall be removed when the arborist leaves the tree.

Scabbards or sheaths shall be used to carry handsaws when not in use. Folding saws, when not in use, shall be closed and hooked to the arborist saddle.

Pole tools used in line-clearance operations shall be constructed with fiberglass rein- forced plastic (FRP) or wooden poles meeting the requirements of OSHA 1910.269.

A separate workline shall be attached to limbs that cannot be dropped safely or controlled by hand. Arborist climbing lines and worklines shall not be secured to the same crotch.

Dry conditions and dead palm fronds present an extreme fire hazard. When dry conditions exist, arborists and other workers shall not smoke while working in or near dead palm fronds. All chain saws used under such conditions shall have mufflers and spark arresters in good working condition.

Palm frond skirts that have three years or more of growth shall be removed from the top down. Arborists performing this work shall be supported by an arborist climbing line and a false crotch. Arborists shall never attempt to remove skirts of three years or more by positioning themselves below work areas while being supported by a lanyard.

Cut branches shall not be left in trees upon completion of work.

Cabling

Arborists and other workers on the ground shall not stand under the work area of a tree when a cabling system is being installed.

Tools used for cabling, bark tracing, and cavity work shall be carried in a bag, on a belt designed to hold such tools, or attached to a tool lanyard.

Arborists installing cabling systems in trees shall be positioned off to one side in order to avoid injury in case of cable system failure that could occur when a block and tackle or a hand winch is released.

Rigging

Arborists performing rigging operations shall inspect trees for their integrity to determine whether the trees have any visible defect that could affect the operation. If it is determined that the tree poses a risk of failure due to the forces and strains that will be created by the design of the rigging operation, an alternate plan shall be used.

The number of connecting links used for connecting components of a rigging system shall be minimized when possible. Care shall be taken to ensure that connecting links interface properly and in compliance with manufacturers’ recommendations.

The qualified arborist shall ensure that load ratings shown on the rigging equipment or provided by the manufacturer for all ropes, connecting links, and rigging equipment are observed in all rigging operations. Rigging equipment shall be chosen for the specific task based on working-load limits and design specifications.

All equipment used for rigging operations shall be in good working condition. Equipment that has been damaged or overloaded shall be removed from service.

When the potential exists for rigging equipment to be confused with climbing equipment, the equipment shall be clearly marked to indicate their different purposes.

Rigging points shall be assessed for their structural integrity by a qualified arborist. The rigging plan and the tree shall be considered relative to the forces being applied to any part of the tree, including branch attachments and anchoring roots, before a rigging point is chosen and established.

Climbers shall choose tie-in points that will provide proper protection while allowing for a separation between the rigging system and the climbing system. Running rigging lines shall not be allowed to come into contact with any part of the climbing system.

Arborists performing rigging operations shall be educated to understand and trained to estimate the potential forces at any point in the rigging system being used. The system components shall comply with working-load limits relative to the operation and the maximum potential forces.

Careful consideration shall be given to the potential forces resulting from the specific influences of rope angles as well as the number of lines and/or line parts that will act on any rigging point.

Arborists working aloft (either climbing the tree or from aerial device) shall establish a communication system with arborists and other workers on the ground.

A method of verbal/visual communication shall be discussed and established during the job briefing, prior to the start of removal/rigging operations. The verbal/visual communication system shall use an established command and response system (see example) or pre-arranged, two-way hand signals. The communication method shall be clearly understood and used during all rigging operations.

Example

Command: Stand clear!

Response: All Clear!, Underneath!, or No!

A work zone shall be established prior to the start of rigging operations. Workers not directly involved in the rigging operation shall stay out of the pre-established work zone until it has been communicated by a qualified arborist or qualified arborist trainee directly involved in the rigging operation that it is safe to enter the work zone. Workers shall be positioned and their duties organized so that the actions of one worker will not create a hazard for any other worker.

Only qualified arborists or qualified arborist trainees directly involved in the operation shall be permitted in the work zone when a load is being suspended by the rigging system.

Taglines or other means may be used to help control and handle suspended loads.

Arborists working aloft shall position themselves so as to be above or to the side of the piece being rigged and out of the path of movement of the piece when it has been cut.

Climbers and their climbing systems shall be positioned outside of the rigging system itself when a cut is being made or a load is being moved or lowered. Climbers shall have an escape plan prepared.

The spars, Iimbs, or leaders being worked on and the spars being used for tie-in and/or rigging points shall be assessed for structural integrity and potential reaction forces that could cause a spar to split when it is cut.

Steps shall be taken to prevent spars from splitting or tearing during the rigging operation, and climbers shall take steps to avoid trapping, pinning, or entangling themselves in the system should the tree split or the rigging fail. Load binders are one possible means of preventing splitting.

Tree Removal

Before beginning any tree removal operation, the chain-saw operator and/or crew leader shall carefully consider all relevant factors pertaining to the tree and site and shall take appropriate actions to ensure a safe removal operation. The following factors should be considered:

(a) The area surrounding the tree to be removed, including nearby trees;

(b) Species and shape of the tree;

(c) Lean of the tree;

(d) Loose limbs, chunks, or other overhead material;

(e) Wind force and direction;

• decayed or weak spots throughout the tree (be aware of additionalhazards if these conditions exist in the hinge area);

(g) Location and means to protect other persons, property, and electrical conductors;

(h) Size and terrain characteristics or limitations of the work area, and

(i) Evidence of bees or wildlife habitation in the tree.

Work plans for removal operations shall be communicated to all workers in a job briefing before starting work.

Workers not directly involved in the removal operation shall be clear of the work area, where practicable, beyond the length of the tree, unless a team of workers is necessary to remove a particular tree.

A planned escape route for all workers shall be prepared before cutting any standing tree or trunk. The preferred escape route is 45 degrees on either side of a line drawn opposite the intended direction of the fall. Obstructions shall be cleared along the escape path.

The chain-saw operator shall use this path for egress once the cut has been completed.

When it is necessary to shorten or remove branches before removing the tree, the arborist shall attempt to determine whether the tree can withstand the strain of the lowering procedures. If not, other means of removing the tree should be considered.

The crew leader shall determine the number of workers necessary for tree removal operations.

The crew leader shall develop a work plan so that operations do not conflict with each other, thereby creating a hazard.

Climbing spurs shall have gaffs of a type and length compatible for the tree being climbed.

Wedges, block and tackle, rope, wire cable (except where an electrical hazard exists), or other appropriate devices shall be used when there is a danger that the tree or trees being removed may fall in the wrong direction or damage property. All limbs shall be removed to a height and width sufficient to allow the tree to fall clear of any wires and other objects in the near vicinity.

Tackle blocks and pulleys and their connecting links shall be inspected immediately before use and removed from service if they are found to be defective.

Workers returning to the work area shall not enter until the chain-saw operator has acknowledged that it is safe to do so.

When a pull line is being used, the workers involved in removing a tree or trunk shall be clear by a minimum of one tree length.

Workers not directly involved in manual land-clearing operations shall be at least two tree lengths away from the tree or trunk being removed.

EXCEPTION

This requirement does not apply in the presence of site restrictions, such as         waterways or cliffs. Other arborists and workers shall be beyond the trees’ striking           range and at a distance as close to twice the tree’s height as practicable.

Notches shall be used on all trees and trunks greater than 5 inches (12.7 cm) in diameter at breast height.

Notches and back cuts shall be made at a height that enables the chain-saw operator to safely begin the cut, control the tree or trunk, and have freedom of movement for escape.

The notch cut used shall be a conventional notch, an open-face notch, or a         Humboldt notch.

Notches shall be 45 degrees or greater and large enough to guide the fall of the tree or trunk to prevent splitting.

Notch depth should not exceed one-third the diameter of the tree.

The back cut shall not penetrate into the predetermined hinge area.

With a conventional notch or Humboldt notch, the back cut shall be 1 to 2 inches (2.5 to 5 cm) above the apex of the notch to provide an adequate platform to prevent kickback of the tree or trunk. With an open-face notch (greater than 70 degrees), the back cut should be at the same level as the apex of the notch.

The two cuts that form the notch shall not cross at the point where they meet.

Before making the back cut, there shall be a command such as “stand clear” from the arborist operating the chain saw and a response such as “all cIear” from the workers supporting the removal operation. Pre-arranged, two-way hand signals may also be used.

Only designated persons shall give such signals. All workers in the near vicinity shall be out of range when the tree or trunk falls. Visual contact should be maintained with the tree or trunk until it is on the ground.

When the back cut has been completed, the chain-saw operator shall immediately move a safe distance away from the tree or trunk using the planned escape route.

Workers shall not approach mechanical tree removal or mechanical re-clearing operations, such as with a rotary or flail mower, until the operator has acknowledged that it is safe to do so.

Brush Removal and Chipping

Traffic control around the jobsite shall be established prior to the start of chipping operations along roads and highways.

Brush and logs shall not be allowed to create hazards in the work areas.

To prevent an entanglement hazard, loose clothing, climbing equipment, body belts, harnesses, lanyards, or gauntlet-type gloves (for example, long-cuffed lineman’s or welder’s gloves) shall not be worn while operating chippers.

Personal protective equipment shall be worn when in the immediate area of chipping operations in accordance with section 1.4 (PPE) in this manual.

Training shall be provided in the proper operation, feeding starting, and shutdown procedures for the chipper being used.

Maintenance shall be performed only by those persons authorized by the employer and trained to perform such operations.

Addendum 1.

Outdoor Heat Stress

Prevention Program

Policy Statement

This program was developed to protect employees from hazards posed by working in the outdoor environment.  Renaissance Tree Care is committed to preventing heat related illnesses that can occur to employees working outdoors by:

• Identifying, evaluating and controlling potential exposure to extreme temperature, humidity, and other environmental factors.
• Providing drinking water
• Providing supervisor and employee training
• Establishing heat-related emergency procedures

Program Scope and Application

This program applies when employees and students are exposed to outdoor heat at or above the following temperature and clothing action levels.

Outdoor work includes any employee assigned to work in the outdoor environment on a regular basis.

This program does not apply to incidental exposure which exists when an employee is not required to perform a work activity outdoors for more than fifteen minutes in any sixty-minute period.

Note: It is possible outdoor heat related illness might result at temperatures below the action levels when employees have not acclimatized to sudden and significant increases in temperature and humidity.  Supervisors, employees should monitor for sign and symptoms of outdoor heat related illness when there is a significant and sudden increase in temperature.

Program Responsibility

Units are responsible for implementing this program as part of their Accident Prevention Program.  Supervisors are responsible for encouraging employees to frequently consume water or other acceptable beverages to ensure hydration.

Employees are responsible for monitoring their own personal factors for heat related illness including consumption of water or other acceptable beverages to ensure hydration.

Evaluating and Controlling Outdoor Heat Stress Factors

In addition to outdoor temperature, supervisors should evaluate other potential heat stress factors.  These factors include:

• Radiant Heat (Example: Reflection of heat from asphalt, rocks, or composite roofing material, or work in direct sunlight)
• Air Movement (Example: Wind blowing and temperature above 95° F)
• Conductive Heat (Example: Chipping)
• Workload Activity and Duration (Examples: Hand sawing, digging with a shovel)
• Personal Protective Equipment (Examples: Chaps, gloves and Helmet)

Supervisors should attempt to control outdoor heat stress factors when feasible.  Controls to consider include:

• Taking breaks in a shaded area (building, canopy and under trees)
• Starting the work shift early (when daylight begins) and ending the shift early and/or not working outside during the hottest part of the day.
• Removing personal protective equipment such as Chaps, gloves and Helmet breaks
• Using cooling vests or headbands

A solid reputation, DigLynden Tree Service Here we are taking out 20 130′ White Firs in a backyard.

DigLynden Tree Service 360-318-9795 knows doing tree service in Bellingham WA is tough.  I have seen at least seven good size companies serving Bellingham go out of business.  The question is what makes a tree service company successful and what kills it?

After nine years in business you get a good sense of the pulse of your industry.  The tree service industry is filled with interesting characters and situations.

One company does estimates in Bellingham in his $50,000 fairly brand new truck.  Very successful, and you pay for it.  About 30% higher than the rest of us, and for one reason.  Because of a solid reputation and time in the tree service business around Bellingham WA, his schedule is usually busy.  Although he was running two crews, but now is back to one, they are usually working consistently.  Having three weeks of business lined up and more estimates waiting means you can charge more, and win less estimates, and still do good.  The service isn’t any better than the other professional tree service companies in Bellingham but you get the privilege of paying the highest prices out there.

I had something I think is pretty funny happen last week with one of my competitors.  DigLynden Tree Service is now running two crews, so I tried hiring one of my competitors to chip up one of the jobs going on.  If it worked I could leverage their equipment and grow even faster, was my idea anyway.  I should have know something was wrong when the owner quoted me $70.00 per hour, including two of his employees, a chipper and a chip truck.  Well, I was told that the two guys chipping were obviously in no hurry, and even looked like they were stalling, but it gets better.  

DigLynden Tree Service can help you make money with your timber. Even a few trees can be worth a lot of money.

The owner quoted me 4.5 hours, about $360, I said fine.  The next day I was at the job finishing it up, he came by and I wrote him a check.  During the chipping the day before the neighbor came over and asked one of DigLyndens’ ground crew for an estimate. Steve told her that I would be over tomorrow to do the estimate.  I guess she told her husband to expect us to come over and give them an estimate to remove a birch tree in the back yard. After the owner of the tree service company got his check for the chipping, he went over to his truck, got a clip board, went up to the door, said hi, the home owner came out and my competitor did the estimate.  I am sitting right across the street working, and watching this happen right before my eyes.  One of his employees told him about the lady coming over and asking for an estimate and he must have thought, all’s fair in love and war.  I should have known a guy that rents his chipper on craigs’ list for $100 a day, wasn’t all there.  Oh well, won’t ever be calling him back for more chipping jobs.  Too bad, it could have been a good start of a mutually beneficial relationship.  Glad I found out early about his character and business ethics.

Ok, you’re asking, “so what, what’s the point”?  DigLynden Tree Service is growing and now has seven employees.  We are growing because we fair, focus on safe practices, and work great as a team, with an attitude to deliver the best service in the tree service industry.  As our schedule has grown three weeks out, we have kept out prices the same.  We feel in the long run, it will pay off.  

Ya, doing tree service in Bellingham WA is competitive, but with the right business practices it can be a wonderful business to operate.  We love it!

The value of the 30 to 40 trees should bring between $2,000 and $3,000.  The size of most of the trees is minimal in producing timber value.  

Job Description:

Remove all trees on the “island” and up to four more of your choice.  

Chip all branch material.  The cost includes as much dumping of the branch material on site

Chips Ahoy!

as possible.

Customer to rent excavator for one week.  DigLynden will provide operator and  dump truck for removal of stumps and dirt.  Any stumps and dirt that needs to be removed from site, will be taken to other location.

Dirt mound where trees are will be brought down to even level with rest of parking lot.

The investment for this improvement is $7,500.00, tax will be added to $5,500.00.  Cost includes $2,000 for excavator.

We appreciate this opportunity.  Let us know what you need to make it happen.

Cedar needed to be removed for safety in Bellingham WA

DigLynden Tree Removal Service 360-318-9795 was at South Bay Drive, in Bellingham WA this week,  a beautiful location to do tree removal service. Even in a monsoon. It rained all day, from start to finish. Don’t remember being that soaked in my entire life.

I was hired to dismantle a 50’ cedar tree that had the potential of tumbling down over a retaining wall. The tree had a definite lean and needed to be removed for safety.
The original plan was to either chunk the tree down from the top or pull it back and drop it on the driveway. The driveway is rock so that wouldn’t have been a problem. There is a pole building in the way but enough room to bring the tree into the drop zone. One apple tree would have had to be moved and a lot of rigging to pull it back and over. And we still would have had to limb some of the large branches to insure not hitting the roof. As we were discussing which way to go with this tree removal, the neighbor’s wife came out into her carport and was watching. I yelled, “Taking down this tree today, care if we drop it on your property.” She said she would go get her husband.

Paul came out and we talked about where the tree would go and about the cleanup of the tree. With a green light we proceeded to bring the cedar tree down by felling it at the base. I hesitate to tell you how many trees Steve has felled but let’s just say it’s “a lot”. 13 years working for a commercial logging company, Steve, has thousands of knock downs.

"it's in the hole"

Our customer’s property sits 20’ about the location of where the tree would be for clean up. The contractors had put in a retaining wall made of huge boulders. When the tree came down, we were hoping that in would roll and or bounce to the ground, but it when the tip hit, the butt ended up staying on one of the boulders. This presented risk for getting the branches off. First we cleaned all the branches from under the tree. I wasn’t sure when the truck would come to haul the logs off and wanted to have that debris ready to chip in the meantime. We then took off all the branches. Because the tree was at an angle and getting under it to remove the branches would have been extremely dangerous, we used a gas powered pole saw to cut the branches off the bottom. With the last branch being cut off, the cedar tree rolled from its position and fell to the ground.

While we were chipping the branches, Paul, asked if we could drop two alders that were leaning over the house. Small trees, but because of where they were I had to climb them and cut them down from the top. Normally no problem but in the pouring rain it was a little more interesting. Got the alder trees on the ground and although I wasn’t asked to buck them up we did it as a friendly gesture. The use of Paul’s’ driveway was golden so it was appreciated with some extra service.

Your timber may be worth money, we can evaluate the value for you.

The removal of the trees to the mill was different on this job. A Couple of months ago I was working at Calvary Chapel Northwest on the Guide and needed some air in one of my tractor tires. Went down to Crazy Bob’s but guess he’s not crazy about air machines. Saw a guy working on a tow truck across the street and went over to ask him for some air for the tire. Mike is the owner of a towing company in Bellingham WA,

Advanced Towing. Nice guy, appreciated his help. Put a card of his in my wallet and plan to use him for my towing needs. Well, I have a constant desire to try to do things cheaper and more efficiently. The normal way to move logs is to use what is called a self loader. Runs $300 to $600 depending on where the logs are going. For two logs it is an expensive way to get them where you need them. Tow trucks run smaller engines and can get into places easier than the self loaders. Called Mike to see if he would be game to pull these cedar logs onto his deck and haul’em for me. He was, so with a 20,000 pound

capacity wench, Mike pulled the logs onto his truck. Beautiful! Cost me $100 and hopefully we got Mike another way to make some money with his trucks.

Advanced Towing of Bellingham is DigLynden’s towing company of choice. Put 360-255-3663 in your contacts under towing. 

We asked Paul if he wanted the chips and he did. Left him a huge pile of cedar chips for his weed defense. If you would like free woodchips, call us at DigLynden Tree Service and we will put you on a running list. When we are doing a job in your neighborhood, we’ll call to see if you still want them.

With the cedar tree all cleaned up, DigLynden Tree Removal Service pulled out, very wet, and headed for home base. 

We don’t always recommend you remove the tree in question but if it does need to come out, our estimates are free. We appreciate the call.
