What our customers say

JLCB 2 weeks ago

We contacted Warrick brothers to ask them about pruning or removing a large cedar in our back yard. Contact was made through their website and a reply was received in a timely manner. An appointment was made for an inspection of the tree and Warrick kept us informed and arrived at the agreed upon time. With the information Warrick provided we decided to have the large cedar pruned as well as several smaller trees.

Devin, Alex, Ryan & Corey were professional and meticulous, both in their work and the clean up. They wind sailed 2 large fir trees, doing a much more thorough job than the previous company I had 7 years ago. They also cut back a long laurel hedge on one side of our yard and split about 26 rounds left from taking a tree down several years ago.

Melissa N. a year ago

Devin and Alex did an excellent job taking down five trees on our property, two of them being 100' tall and requiring extra time and careful planning. I found their team to be extremely professional from bid through completion.

Our certified arborist

Devin Warrick

ISA Certified Arborist with a Tree Risk Assessment Qualification

Certification PN 368801A
Verify it on treesaregood.org
Licence Washington contractor licence WARRIBT777DF
Verify it yourself on LNI.wa.gov

Devin is our certified arborist, and he learned this trade on a crew before he learned it in a book. He climbed, ran ground, shadowed estimates and permitting, then worked alongside certified arborists at a larger company and studied tree biology properly. He carries the ISA Certified Arborist credential and the Tree Risk Assessment Qualification, and that is the standard he sets for how this company reads a tree. Every estimate we write is written against it, which is why the answer you get is about what the tree needs rather than what is easiest to sell.

  • The yard the way we found it

    We chip, haul and rake as we go. Our own chip truck means the brush leaves with us when we do.

Some of the work

Real jobs, and we wrote them up ourselves. Where a camera recorded the date and the time, we have put those on the record too.

Snohomish County

A side yard given back in one morning

A laurel and a conifer had grown across a gravel passage down the side of the house, tight against the siding, with a rock retaining wall on the other side and nowhere to swing anything. By late morning the passage was clear end to end.

Both photographs came off the same camera, from the same spot, two hours apart. The first is stamped 09:33 and the second 11:23. We have put the times on the record because they are the camera's, not ours.

Three cottonwoods at Christ the King, Arlington

At Arlington's own Christ the King Community Church we removed 3 GIANT Cottonwoods in 2024

Cottonwood is one of the heaviest and most brittle things we take down in this county, and three of them on one site is a genuine day's rigging.

Over 200 feet of arborvitae in Arlington

At this job, here in Arlington, we topped an arborvitae hedge that was over 200 feet long

Cutting a hedge to a line is not the same thing as topping a tree, and we say why on the hedge page. On a run this long the whole job is holding one straight cut for 200 feet and getting every scrap of it off the property.

Who runs this company

Two brothers, one crew

We are Devin Warrick and Alex Moon, and we are brothers. We started Warrick Brothers on weekends in 2023, went full time this year, and we still run it ourselves.

Devin Warrick

Owner and Operations Manager

  • ISA Certified Arborist
  • Tree Risk Assessment Qualified
  • Estimates and climbing

I grew up around this work. My uncle was a climber, and splitting firewood for him is how I started. I came back to trees through groundwork, then climbing, then estimating and permitting, then tree biology alongside certified arborists at a larger company.

I hold the ISA Certified Arborist credential and the Tree Risk Assessment Qualification, and I set the standard every estimate this company writes is held to.

From the reviews

Devin and Alex did an amazing job for me. One tree in particular, I knew needed some expertise to fell it without a problem.

I would rather tell you a tree can stay than sell you a removal it does not need.

  • Climber
  • Runs jobs and crews
  • Estimates

Devin and I started Warrick Brothers together in 2023, as weekend work while we both had other jobs, and we took it full time this year. I climb, I run the crew on site, and I run estimates the same as he does.

Between us there is close to 20 years of combined experience in tree work. Most of what we take down in this county comes out in pieces on ropes because there is a fence or a roof underneath it.

From the reviews

Alex and his crew did a great job taking down a big Madrona that was growing over the neighbors garage and a big fir tree.

I would rather take an hour longer and put every piece exactly where I meant it.

Where we work

Fourteen cities across Snohomish County, Camano Island and the top of King County. One crew, one base in Marysville, and a drive time we keep honest so we turn up when we said we would.

Just outside that list? Call us anyway. If it is a reasonable drive we will usually come and look.

Questions people ask us

Why can you not just quote over the phone?

Because what decides a tree job is rarely the tree. It is the access, the ground, what is underneath it and how close a chipper can get. Two trees that look identical from the street can be a full day apart in work once somebody has stood under them. Quoting blind means either padding the number to cover the unknowns or finding out on the day. Neither is fair to you.

Do I need to be home for the estimate?

We would much rather you were. The estimate is a conversation about what you want the property to look like afterwards, not just a look at a tree, and the useful version of it happens with you standing there. It takes 20 to 30 minutes and it is free. Ideally everybody whose approval the job needs is there too, so nothing has to be relayed secondhand later.

What does a certified arborist actually change?

The decision, not the cutting. Plenty of people can take a tree apart safely. Far fewer can tell you whether it needs taking apart at all, what a particular cut will make the tree do in five years, or whether the thing frightening you is a real defect or just a big tree behaving normally. That judgement happens at the estimate, before any money is spent, and it is where the certification earns itself.

Why will you not top a tree?

Because it makes the tree more dangerous, not less. Cutting the head off a conifer leaves a large wound that decays, and the tree answers with a crowd of shoots attached to the outside of old wood rather than into it. Within a few years the view is closed again, the regrowth is denser than the original crown, and the parts holding it up are the parts most likely to fail. You have bought three summers and a worse tree.

What happens to the wood and the chips?

That is your call and we ask at the estimate. Brush goes through the chipper. The trunk and limbs can be cut into rounds and stacked where you want them for firewood, left in longer lengths, or hauled off entirely. Chip leaves with us by default, but if you want it for beds or paths we will blow it into a pile wherever you point. Hauling is its own line so you are choosing rather than paying for it by default.

Are you licensed and insured?

Licensed, bonded and insured, and we have been since the first day the business existed. The Washington contractor licence number is WARRIBT777DF. Ask any contractor for theirs before you let them near your property, and if they hesitate, that is your answer. We would rather you checked ours than took our word for it.

What will you not do?

We do not top trees. On a removal we will grind the stump out if you want it, but we do not book stump grinding as a job on its own. We do not spray anything, so no pest treatment and no feeding. We do not quote over the phone or from photographs. And we do not tell you a tree has to come out when it does not, which is the one that costs us money and is the reason people call us back.

Can I spread the cost, and how do I book?

Financing is available through Affirm on the invoice, and we will walk you through it if you want it. To book, call or text (360) 842 7433, or send the form on our contact page and one of us will call you back. Estimates run Monday to Friday between 9am and 4pm, and we ask for about 48 hours notice so the right person is the one who turns up.

Have a certified arborist look at it

Tell us what the trees are doing and we will come out, walk the property with you and write it up. The visit is free, it takes about 20 to 30 minutes, and you get an itemized estimate you can hold on to.
