"I would highly recommend Arborist of America for all your tree work needs! William Byrd, owner of Arborist of America, and his crew did an exceptional job in completely removing two 100 foot trees of mine and did it in timely manner with no damages to my or the neighboring properties. William is very professional and very knowledgeable in tree work and trees in itself. I would definitely hire Arborist of America again to carry out any tree work of mine."

"From the first contact until the work was completed, Pacific Northwest Arborists was a professional, friendly company to do business with. Keith, the owner, came out to bid. I was impressed with how invested he was in saving our trees. Other companies we contacted were encouraging us to remove the trees. Keith offered realistic explanations and solutions to the various problems. Even to the point of saving a sapling shoot that was sprouting from the remaining birch stump in hopes that a new tree would result. The bid was very reasonable. The work performed and the cleanup following exceeded our expectations. I have already recommended Pacific Northwest Arborist to a neighbor and would not hesitate to use their services again."

"I hired Pacific Time Trees to trim and shorten our arborvitae hedges that had gotten completely out of control over the years. They also took down a good-sized birch tree. They showed up on time and did the work very efficiently. It was a big job, taking hours to complete. Carlos, the supervisor (who is also an arborist), managed the project. Then, based on their work on the front yard, I had them come back a few days later to do a similar project on the back yard hedges. They brought a large box truck with a trailer-towed chipper. Their cleanup was excellent on both projects. Their whole crew was very pleasant to work with. I would definitely recommend these guys for any similar projects."

"This company provided excellent service. They trimmed a very overgrown hedge and removed 5 arborvitae trees that were leaning against my house. They removed all of the debris and did an excellent job. Juan checked with me to make sure that he had trimmed the hedge the way that I wanted it."

"We purchased a home in 2011 in southwest Portland that sits on nearly an acre of land. When we moved in we thought how nice that the house was surrounded by woods (privacy and nature galore). We have since realized that this 'natural retreat' caused two primary problems: not enough land for the kids and adults to play even though we had an acre footprint, claustophia as the brush and ivy and blackberry bushes slowly closed in around us. I love the house and the land, but don't be fooled, maintaining an aestheticly pleasing landscape when your house is 'in the woods' is a tremendous challenge. What at one point can seem like a intentional, mature, focused landscape can quickly transform into an  overgrown mess. We contacted Douglas and Ramos Cleanup to intitially clear one of the  side yards and lay barkdust. Douglas made an immediate effort to come to the property and promptly provided a bid. The bid was reasonable and lower than one other company I contacted. My wife and I decided to hire Ramos. Perhaps the best decision we have made since moving  into the house two years ago.
These guys are unbelievable. They came on a Saturday exactly at the time they said. By the time they had finished, my wife and I had decided to hire Ramos to perform a much more comprehensive clearing project. The idea was create a clean and groomed mature landscape all the way around the house that would act as a buffer to the forest that remained at the perimeter of the property. They came back the next two days (working 10 hours on Sunday) with a team of 6 or 7 and literally transformed the property. When they finished, my wife and I simply walked around the land dumfounded. They not only cleared trees, massive stumps that had been swallowed by ivy, blackberry bushes, years of overgrowth; they also new exactly what to perserve. They trimmed the shrubs and trees meticulously, uncovered plants we never even new were there, and made everything look spotless. My wife immediately commented how relaxed the place now made her feel. Bingo. They gave a bid at the beginning of the project and stuck to it even though they uncovered (literally) challenges (huge old growth stumps) along the way. I don't even know how many dead and dying  trees they removed, but it was a ton. They even cleared a larger area in the front of the house because they knew that was what was needed to make it all come together. I can't say enough good things about this company. Hire them without concern (and I rarely have ever said that about any company). They are the only people I will use for now on. They are professional, courteous, efficient, and knowledgable. They busted they tails to transform our property. 10 out of 10.

"Eli’s Tree Service, a family-owned business, recently trimmed and cut back several extremely tall tree limbs that were threatening my mother’s gutters and roof. The crew did an outstanding job. The men expertly handled the tree trimming while the women kept the work area clear and efficiently fed the branches into the chipper. It was impressive to see such great teamwork and professionalism. In addition, they removed a large dead shrub, leaving the property looking much better. Their prices were very reasonable, they arrived on time, and they responded promptly to our request. When the job was finished, they thoroughly cleaned up the property and made sure everything was completed safely and professionally. We are extremely pleased with the quality of their work and would highly recommend Eli’s Tree Service to anyone looking for reliable, affordable, and professional tree care. Thank you, Eli, and your entire crew. You are truly appreciated!"

Arborists questions, answered by experts

For Bradford pears, damage from storms is common, and if the trunk splits, it can pose a danger to people and surrounding structures. The best thing to do in that instance is to have the tree removed. If there’s only minor damage to the branches, pruning away the damaged parts is the first order of business. You may also want to consult a professional arborist to make sure the tree is healthy.

The cost of trees varies massively based on the size of the tree and the species. A small Colorado spruce can cost as little as $30, but a golden rain tree of the same size can cost $90. Large trees can cost $1,500 or more, depending on their species and height.

If you’re looking to rot a tree stump fast, potassium nitrate will work far quicker than copper nails. First, drill several holes into the stump using a power drill, then pour potassium nitrate pellets into the holes. Next, add water to help the chemical absorb into the wood, thoroughly soaking the stump to ensure the pellets dissolve and spread evenly. Afterward, cover the stump with a tarp to retain moisture and block sunlight, then place mulch on top to secure it in place.

A tree growing close to a house can pose several risks, but removal isn't always the only or best solution. Potential problems include roots growing into the foundation and causing structural cracks, branches damaging the roof or promoting moss growth, and debris clogging gutters, which can lead to water damage. Trees can also provide access for pests and encourage mold. However, a small, healthy tree may not be a problem, and for larger, established trees, strategic trimming can be a cheaper and more beneficial alternative to removal. It is generally recommended to take action for trees within 10 to 20 feet of your home, especially if they are unhealthy or encroaching. Your best bet is to consult a professional arborist who can assess the specific situation and provide expert advice.

Yes, it is essential to confirm that any tree service company you hire is properly insured before they begin work. Tree removal, trimming, and pruning are dangerous jobs, and proper insurance protects you, your home, and the company from liability in case of accidents or damage. Look for a company that carries both general liability and workers’ compensation insurance, and do not hire one that cannot provide proof of coverage. When browsing for professionals, you can look for indicators like an “Angi Approved” badge, which signifies that the business meets standards like holding applicable licenses and passing a background check. Keep in mind that a license is a legal requirement to operate, while certifications are typically voluntary.
