"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."

"Pacific Time Trees did a great job removing 2 trees from our yard - one that had died and another that was overgrown in a tight location. Carlos and his crew chipped everything (even chipped an extra pile of trimmings we had!) and left the site clean. Both Cesar and Carlos were very responsive and good about communicating timing for everything. They got the job done quickly, and at a very reasonable price. We will definitely use them for any other tree projects we have!"

"I initially met with Francisco and he was very informative and helpful. He explained the process and I really enjoyed how much I learned from him. I was not home when the crew came to cut my trees but when I returned home I was really happy with what they had done. I would definitely recommend this company."

"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.

"Professional, knowledgeable and did a wonderful job. We had 2 large trees removed from our property that were both near our house and they did exactly what we wanted and cleaned up really well. We will absolutely use them again when we are ready to remove other trees from the property."

Arborists questions, answered by experts

Signs include dead branches, growth over structures, diseases, pests, or roots impacting hardscapes.

Yes, it’s okay to trim low branches on a tree, also known as limbing up or raising the crown. Essentially, you’ll trim the lower third of the tree (trunk) and leave the upper two-thirds of the tree (crown). Arborists recommend trimming 20% of a tree’s leaves per season for two to three seasons. Trimming low branches allows light to flow through the tree, increasing circulation and making the tree stronger and healthier.

In most cases, you should not use a pruning seal on trees after trimming. Applying a sealant can interfere with the tree's natural healing process, and it does not guarantee protection from pathogens. Instead of sealing the cut, the best practice is to support the tree's natural recovery by providing it with plenty of water and a dormant-style fertilizer. However, there are exceptions. Pruning seals may be recommended for very vulnerable species, like elm trees, in areas where dangerous diseases such as Dutch elm disease are prevalent. In these specific situations, the protection offered by a sealant can outweigh its downsides. For advice tailored to your situation, especially after cutting large branches, it is best to consult a local tree trimming professional.

There are a few instances in which removing a tree is the best option. You might do this if the tree looks to be a major danger—potentially falling onto your home, your car, or other parts of your property—or it’s diseased beyond repair. A tree that is growing too close to your house might need to be removed to prevent mold growth.

Whether you grind or dig up and remove your tree stump depends on your landscaping goals. Using a stump grinder leaves the root system in place for it to decompose over time, whereas digging up the tree stump removes the roots and the stump. Overall, stump grinding is a far simpler process since you won’t need to deal with the roots. Stump removal will make your yard look like a demolition site, but you’ll have an easier time replanting in the same place as your former tree.
