“I've used Davey Tree for years, and I'm happy. They have been excellent. They do major pruning, tree fertilization, and pest control on my azaleas. They are very good, and they've been very punctual. I would grade them as an A+.”
“I'm very happy with Davey Tree. I love the technician that comes. He's very nice, capable, and friendly. I'm happy with everything. They come almost every month for lawn care, and if I need tree service, I'll call them. I would give them an A+.”
“They're outstanding. They described the work that needed to be done, and they did it perfectly. They're an A+ company.”
“They did lawn and tree treatment. They were very prompt and thorough with their treatment, and they were very good and very careful. I would give them an A+ grade. I have actually already recommended them.”
“They do major tree work for us, and they do some test work for us as well. There is a particular person that we like to deal with there who is very good. His name is Derrick. He is the only one I deal with there. My overall experience was excellent. The guy that comes to spray for our pest control, he is fantastic. It's affecting my trees, and we've had it for several years, and the person—I don't know his name—that comes to do that is superb. He is very kind to go to our bird baths and turn them over so they don't get pesticide in them, and he covers up our herbs—I never think of that. I recommend them.”
“They trimmed the trees, worked on the bushes, did some fertilizing, and generally maintained the health of the plants. I would grade them an A+. They usually call me a day before they are coming. The plants are living, that 's what we are after, and the trees, we think, add value to our house. That's why we use them.”
“They have done landscaping, tree trimming, tree removal, and additional landscaping. I would grade them an A.”
“They did do a good job. They do monthly service to my yard. I would grade them an A. They were fine. Their expertise was good.”
“They did some work that I needed done for some bugs on my azaleas. Everything is fine. I've been using them for years.”
“I would recommend The Davey Tree Expert Company for tree service.”
“They deep root seeded all of the trees, they sprayed all of them, particularly the box trees for spider mites, and they took care of an ash tree. They also do some heavy cutting, They are great. I would grade them an A. They come when they are ready to come and when the yard is ready for them to come. I have a contract with them and have recommended them many times.”
“They have been fertilizing. I would grade them an A. We have already recommended them.”
“Davey Tree mostly does fertilizing, but they also do some pest control and some trimming. I would grade them an A.”
“They took down a tree for me and treated another tree for me. I would grade them an A.”
“They cut two crepe myrtles, and then a third. I would say everything was great, and I would very likely recommend them.”
“They did some fertilization on our trees. I would grade them an A.”
“They mainly come to spray the trees and bushes for a variety of insects. I would grade them an A. I found a problem with a couple of my trees so I called several companies to send an arborist out to find out what was wrong. The others said they could make it in two to three weeks, but Davey was out in 36 hours.”
“The Davey Tree Expert Company has done tree removal and stump grinding for me. I would grade them an A. The gentleman, their arborist, is kind and courteous. He seems like he's a generally respectable person.”
“My experience with them was excellent. They're amazing. Their level of knowledge is fantastic, and each person they sent was great. They were just great; the care, concern, knowledge, time—everything. I've already referred them to people because it's hard today to find companies that provide good service and are nice and knowledgeable. It was just so refreshing. It was great; just fantastic. They came out to look at my tree. I had a tree that was partially dying because of bugs of some sort. Then, they went around, looked at all my trees—I have elm trees that have the emerald ash borer—and they came back and treated them. They will come this year and treat them, too. I'd give them an A triple plus; I don't think there is a grade high enough for them.”
“They were excellent, and they did excellent work. They were very professional—both the individual who came out and did the estimate and the team that came out. They were all very nice. They introduced themselves, cleaned up everything, showed up on time like they said they would, and all the work was fantastic. I had them come out twice. The first time, they trimmed one tree in the backyard; the second time was still part of the same order, but we waited until the crape myrtle had gone dormant to have them come back and trim that up. They also did some additional limb work. I'd give them an A+.”
“They were prompt, and they did a good job. The other thing was I didn't even know the tree was cut from how well they cleaned the debris and all that. They were very good. They shaped it up—it was a little too tall and hanging over the neighbor's yard. They did a beautiful job bringing it back on my property and all. I'd give them an A+. I'm completely happy with the job.”
“Davey Tree is our tree service company; we always go to them. We've never had a disappointing time with them. We've lived in this house 45 years, and they've done work for us a number of times—we wouldn't have come back to them if we hadn't been satisfied. We're very, very happy with Davey. They're a reputable company, and they do a good job. There were about 10 or 11 things that we wanted them to take care of for us. There was an oak tree that had died, and my wife decided that she wanted it cut off about 20 feet from the ground to leave a tall stump that the woodpeckers could work on. After a while, the woodpeckers had done their thing with it, and so we needed to have Davey come back. Both of those jobs they did extremely well. We did have to wait a while for them to come back out to do the stump because, of course, they had to wait until the crane was available. The stump was a relatively tall, big piece right between our house and our neighbor's house, near our property line. We wanted to make sure there was no damage to anything or to our neighbor. They did a very fine job on that. Last August, in addition to topping that tree, they took everything down to about 20 feet off the ground. Then, they also did major trimming on a dogwood, a crape myrtle, a hemlock, and a big, 40-year-old arborvitae that were badly overgrown. In the backyard, they were primarily working to take off limbs, remove dead branches, and reshape things to make it look better and healthier. The team that came out here to do all that work was very professional. They had the work order, and they knew what they were supposed to do. However, there were a couple of things on the work order that we either did not understand correctly or wanted to change, and they were very agreeable. There was a small miscommunication when the order was first written, as far as us being on the same page. So, everything went fine, and they got it all done in one day. It was a big job, and they had three guys out here, I think. It was all cutting, hauling, and cleaning it up. My wife was a horticulture major in college; she knows quite a bit about plants—how to grow, maintain them, and things like that. She has done this for the better part of her life, mostly on a hobby basis. We picked Davey because they had a certified arborist on staff that was able to talk to my wife intelligently and not try to snow her with a bunch of fancy footwork or anything. We just like the company. We had had a little bit of work done by another company, and the things we had them do, we weren't too worried about because it was stuff they couldn't mess up, really. But then we decided we wanted somebody more professional to take care of the landscaping after we'd been here a few years. I'd give them an A+.”
“They did a good job. They took care of the trees. They did an excellent tree removal for me. They removed a stump, and they did it quickly. The customer service was part of it. They did the trees quickly, and they did a good job. I'd give them an A+. I had no complaints.”
“They were very easy to deal with on the phone. The office people and the workers who came here were very easy to deal with. I thought they were very efficient. We had a considerable amount of pruning done on some trees and bushes. The reason I chose them is because we had some work done by them a couple of years ago. I'd give them an A+. I would definitely use them again.”
“The experience was good. They were just easy to deal with. They took out some trees in the back and treated a tree. The reason I chose them over another company is because they were recommended by a neighbor who had a good experience with them. I'd give them an A+.”
“They were responsive, and they did a good job. They pruned a maple tree. I found the company because they actually service our community. They do the pruning here in the community, so I hired them to do something individually. I'd give them an A+.”
“I've been very happy with them. When they make an appointment, they keep it. Their crews are very professional. I didn't have a fear that somebody was going to be hurt on my property because they knew what they were doing. Their crews get along—there is no tension, so the men who are working like each other—and that matters to me when they're at my house. I have two homes, and they've taken down trees at both homes. One of them was kind of tricky in the backyard because it was near some other trees that we really wanted to keep safe. They got it down with no trouble, and when they were finished, every trace was gone. Also, a tree they took down in the front yard, they said that because it was so close to the power line, they would prefer to do it with their cherry picker. They asked us to wait because the people they normally get that from had it, and it was being repaired. But they were reasonable—they called, and they gave us lots of notice saying they had just found this out and asked if it would be OK if we did it a certain way. Then they came, took it down, and hauled it away. They left the bushes that were underneath intact. I'd give them an A+. I've been happy with them. They sent me a notice that ash trees now could be inoculated so I've been meaning to get in touch with them. I would use them without hesitation.”
“They did a good job. I'd give them an A+.”
“We have fruit trees—the leaves were spotted and didn't look right, so we asked them to come out and look. We looked around and contacted Davey Tree; they came out, sprayed, and did a few things. It was a couple of treatments over a couple of months or something, and we're going to have to wait and see. The reason I chose them over a different company is because of Best Pick Reports. They did a fine, professional job. I'd give them an A+.”
“I've used them for 15 or 20 years maybe—a long time. They're very quick to come out to give me an estimate, and generally, depending on the time of year, they're pretty quick to come out to do the work. I've been satisfied with the work, so I just go back to them when I need tree work. They trimmed back a cherry tree in my front yard, and I was not home when the work was done. I've never even gotten estimates from anybody else. I've been satisfied, so I just keep calling the same place. They get an A+.”
“They do a good job, and they do it promptly. They seem to always do it very well. They trimmed back three trees and some bushes. I'd give them an A+.”
“They did a really good job trimming the trees. The salesman was fine. The reason I chose them over a different company is because we were familiar with them for most of our life; our neighbor also used them and was satisfied. I'd give them an A+. There were no issues at all. They did a good job and cleaned everything up. They did what we asked.”
“They did what I asked them. They pruned my tree. I chose them because I saw my neighbor use them. I'd rate them as an A.”
“I have them under regular contract. They do quality work. I have them come out for regular pruning that requires a bucket truck. I have them put dormant oil on one of the trees and deep root feeding for another. The reason I chose them is because they've done better work than the other companies have. They know what they're doing. I'd give them an A.”
“They did my trees and then recovered the lawn a lot, so they also did shrubs. They did deep fertilization. I can't tell whether it made a difference because we've had winter, and I think we should wait another month. The reason I chose them over a different company is because my neighbor used them. I think they were fine. They should have an A.”
“I like their professionalism. They come in, and they tell you what they're going to do. They get it done, they clean up, and they leave. I have no complaints. The reason I chose them over a different company is because of my experience using them. I've been using Davey now maybe for 20 years. I'd give them an A.”
“They were very good, and I've renewed my subscription. I'd give them an A.”
“They did exactly what they said they were going to do. They killed a fungus on a tree, and then they started to fertilize the tree to revive it. The reason I chose them over a different company is because of the brand, probably. I'd give them an A.”
“They were effective. They came out and gave me an estimate that was very clear; it explained exactly what needed to be done. They came out in a timely manner and did it—we were just pleased. We've used them many times in the past. They've cut down trees for us. This last time, they gave a fertilization injection to a tree that was not looking so great. I chose them because a friend had recommended them. I'd give them an A.”
“The person that came to estimate the job communicated clearly. Knowing the pros and cons of different actions helped us decide what we wanted done. The crew that came out knew what they were doing. I pointed out a few things that were specific to our particular setup; they understood what I was saying and made adjustments in their work to match the situation. The work they did was more than satisfactory. They trimmed a variety of trees, and they put something between trunks and a split-trunk tree. I chose them over a different company because my daughter has experience in historical preservation and has worked with them before; she recommended them. I'd give them an A.”
“They did the tree in the front yard. We had a bad experience with a similar company about a year earlier, and they did everything kind of the opposite. They did what they said they were going to do. They did it quickly, and they cleaned up when they were done. Basically, they just did a lot of trimming on a tree in the front yard—a lot. I'd give them an A.”
“I thought that they were courteous, and they made an effort to please me. They took down the trees; they didn't damage the other trees and the things that would have been in the way if they hadn't been careful. I thought they did a really good job. I was pleased with the service that I got from them. The reason I chose them over a different company is because they were referred to me originally by a neighbor. I'd give them an A.”
“They knew what they were doing. They came in, did it, and cleaned up after. They trimmed three trees. I'd say they get an A.”
“They came when they said they were going to come. They let me know when they were here; they didn't just kind of sneak into the yard. They knocked on the door and told me they were there to do the work. The schedule was good. They did what they said they were going to do when they said they were going to do it, and they did it well. They did some insecticide treatments and fertilizing treatments around several of our trees. They removed two trees and ground the stumps of the trees that they removed. The reason I chose them was that I knew their name, but I was also referred to them again through the landscaper that was doing some work at our house. I'd give them an A.”
“What stood out for me was that I didn't have to think about it. I have all sorts of things that they do throughout the year. I'd give them an A.”
“They were very pleasant. They came and took down a tree that needed to come down. They did exactly what I asked, and they cleaned it up well. I thought they did a good job. It was a tree that was on the verge of dying, and the arborist had recommended that it needed to come down. It's in a woodsy area, so they just took it down and took it away. I'd rate them as an A.”
“They did a fine job. I'd give them an A.”
“Back in the fall, they did some pruning. I have a tree that has a disease; I don't know what it is, but they're taking care of it. They're supposed to be back next month to follow up on it. I started using them about 20 years ago or more. They just seem to know what they're doing. They are definitely A-quality people.”
“My experience with Davey Tree was excellent—they're amazing. Their level of knowledge is fantastic, and each person they sent was great. I've already referred them to people. It was just so refreshing. I'd give them an A+++; I don't think there is a grade high enough for them.”
“They did excellent work. They were very professional—cleaned up everything, showed up on time, and all the work was fantastic. I'd give them an A+.”
“Davey Tree was excellent. They did a very beautiful job. They trimmed two trees—holly trees. The work was very good. I'd give them an A+.”
“They were prompt, and I wouldn't even know the tree was cut because of how well they cleaned the debris. They did a beautiful job. I'd give them an A+—I'm completely happy with the job.”
“They trimmed the tree in front of our house. It was extremely satisfying. They did a good job, and they cleaned up well, so there were no issues. They did not have to come back afterward—everything was done on the first day. They come out annually, since I usually have it trimmed once a year or so. I chose them because I heard some things about them. I had an arborist that had his own company before, and he got out of the business, so he recommended Davey Tree several years back. I would give them an A+.”
“The guy did some work for us a while back, and it was absolutely outstanding. We're very pleased. The work was fine, the trees look great, and I'd give them an A+.”
“They were very good, excellent. I'm very happy, and I'll be calling them again for future work. I'd give Davey Tree an A+.”
“They did a good job. They came out first to go over things. They were there on time, they made sure they knew what we wanted, and they did a great job, too. We were going to have the trim on our house painted, but the trees had grown too close to the house, so they came out and cleared the area for us. I thought I'd try them out, and they did a great job. So, I would use them again, and I'd give them an A+.”
“They did some tree work for me. They were fabulous. I'd give them all a ten out of ten.”
“Davey Tree does a wonderful job, and I'm very pleased.”
“They've done tree work for me for a year, and they did it recently. Mario was the manager as usual. They work as outlined by the arborists, and they do good clean up in both my yard and the neighbor's yard, picking up fallen branches. They look out for the health of the tree, and I also had them fertilize. I only had pruning done this last time, but I have the fertilization annually. They have a good reputation, they do good work, they clean up, and the trees have remained healthy. I'd give them an A+.”
“I had Davey Tree—they did do work for me. I thought they were very professional, and they did a very good job. They sprayed my trees—they may have come two times to do it—and they sprayed my hemlocks. They also cut down three trees—some of them were small. They might've trimmed up the branches on one tree, too. I was pleased—I've used them through the years, and I think they're fine, an A+ company. I have no complaints about the work they did or with the way they treated me.”
“They did their job. They did some tree fertilizing. I've had used them before, so I'd give them an A+.”
“They were taking down a tree, which overhung a deck and a hot tub, and their people were very careful about not damaging the hot tub or the deck. I chose them based on prior good experiences. I am very happy with Davey Tree. They're an A+.”
“They're very easy to work with, and I didn't have any issues. They came out, they looked at the work, they estimated it, and they did it very quickly, no problems. I've used them a couple of times, so every time I use them there are no quirks. It's pretty straightforward. They've done tree pruning on some of the smaller trees a couple of times, and they've taken out larger trees, like the oak tree, and ground down stumps several times. I had a friend who picked them, so I used Davey Tree based on their recommendation.”
“They've done work for us before. Actually, they took out two small trees this time, but they came a couple of years ago, too. We liked the way they trimmed the trees. They paid attention to all the things we asked them to do. They have a lot of expertise—we don't know how to trim trees and they just said, 'We can do this, we can do that.' I think they were originally recommended to us by someone in the neighborhood. I'd give them an A+.”
“They did the work in a short period of time, and they cleaned up after themselves. They trimmed a bunch of trees. They were in the Best Picks book for Fairfax County, and I'd give them an A+.”
“They did what they said they were going to do. They came out when they said they'd come out and did exactly what they said they were going to do, and that was nice. They arrived on time. They did a soil injection to take care of some scale pests on some holly trees, and then they also sprayed for insects. I heard good things about them, so I chose them. They're an A+ to me right now.”
“We actually had some work done on the tree by somebody else about a year and a half before, and they did a terrible job. So, relative to that, they did well. Davey Tree was there when they said they would be there, and they did a job that looks much better. The tree was damaged at the top, so they cleared out the damage from weather, and at the top, they kind of reshaped it. I'd give them A+.”
“They did some work about a year ago. They did everything I requested for them to do. I have no complaints, and I will use them again and refer them. They're an A.”
“The man who did the estimate explained things very well, the work seemed to be done well, and they carried all the debris off. It's been a few months back, but I think they basically did limb thinning at the top. We've used them for a long time. I would rate them as an A+.”
“They did what they came to do. I chose them because they're arborists. They'd be an A+ in my book. They did what they did, and they left.”
“They told me what they were going to do, they came and did it, and everything was fine. They cut down a large tree out back. I had used them some years before when I had two trees out back. I heard about the company because I live in a very small neighborhood. People here had used their services I guess, and I would just ask neighbors, 'Who do you use to do your trees?' I'd give them an A+ grade.”
“Davey Tree was easy to work with, they did what we asked them to do, and they did a good job. They came out, looked at all my trees, and conditioned them. The quality of work was good. I had never used them before, but they were good, and I would recommend them. The workers were very nice, so I would give them an A+ rating.”
“They're good people, and they did a good job. They came in, they did the work, they left, and there was no problem. They took down a tree for me. I've been using them for over ten years, and I've had good experiences with them. Other companies I had poor experiences with, but Davey Tree always comes through. They've taken down big trees around my house, and they've done a nice job. I would give them an A.”
“They did do some tree work, and they were good. They did a good job.”
“They've been great. I like that I don't have to think about it, that they just come, take care of it, send me a bill, and it's done. I don't have to worry about it. It's nice. They've come a couple of times. I first heard about them from the lady we bought the house from—she was using them. They're an A-grade company.”
“I basically liked that they cleaned up after themselves—you could barely tell they had even been here when they left. They were professional, they were on time, and their workers were personable, but not overly so—they were very professional as well. I believe one of my neighbors had used them and suggested that I give them a call. I'd definitely give them an A.”
“I like Davey Tree a lot, and they've worked with us for years.”
“A couple of our fruit trees had problems. I chose them because they answered the phone first, but I'd give them an A.”
“They did do some work for me. They seemed very confident, they did the work within the amount of time they had estimated, and the work seems to be of good quality. They did some tree trimming around some power lines. They also put two cabled bracings in a tree that had multiple trunks to help protect the trunks of the tree from falling over and to protect it from the power lines coming into the house. I chose them because my daughter—who does historic preservation in this area—recommended them to me for the work. I would give them an A grade, because what they did was what I wanted them to do.”
“I used Davey Tree Expert Company recently. All of the people I have used have come from Best Pick Reports. They pruned trees that were too close to the house. One of them, which had a large branch, was getting too close to the roof. They haven't bloomed yet, but I presume that they will though. I would rate them as an A.”
“Davey Tree took care of my tree services. They were great, and we were very, very pleased. I have them on my cell phone. They were informative, they did a good job, and their prices were ballpark, so I was very pleased. The next time the trees need work, I definitely would call them again. I chose them to begin with because my neighbor used them and referred them. They get an A rating from me.”
“We've used Davey Tree for probably the last 15 or 20 years. We like the quality of their work, and we can trust them to do a good job. They took out a tree trunk that was about 18 feet long, and they did a very professional job on it. It was just as smooth of an operation that you could hope for. I would give them an A++.”
“It was fabulous—I'd recommend Davey Tree to anybody. The guy that came out to talk to me and did the work, I mean—so super professional; I would never call anybody else. They looked at some trees, and they treated some elms. They're an A+.”
“I'm very happy with Davey. They're professional, and the people involved obviously knew what they were doing. It was some complicated work involved: cabling, putting in a rod through the trunk, applying pesticide to the area around the tree, and so forth. I was very impressed—they did an A-grade job.”
“We hired The Davey Tree Expert Company from the Best Pick Reports book. We're impressed with their service. They came right on time, gave us very professional service, and cleaned up all of the yard debris from the tree service they conducted. We'd give them an A+.”
“They do very good work. We have them out every couple years to prune all of our trees if they're getting larger and older and everything. They do an excellent job. They put cables in a few of our bigger trees so we won't have a problem with branches falling on the roof or anything like that. They're very professional. An arborist comes out and assesses, and then the team of people comes out and does the work. They do an excellent job, and they leave it very neat. They climb up in the trees, and they're huge and very tall. They just seem to do a safe, professional kind of job. I'd give them an A+.”
“They came in, picked the tree out, and did a good job cutting it down for me. I think they did fine. I didn't have any particular issues—they didn't have the tree fall on the house or anything. I'd definitely give them an A.”
“Davey Tree did tree trimming. I really liked it. Their response back was great. The work was good, and even the afterward filling process was smooth. They get an A+ from me.”
“They do a good job. I've used them maybe for the past five or six years. They're reliable, and they do what they say they're going to do. Most recently, they trimmed a maple tree. I give them an A+.”
“If you have any major tree work to be done, plan on doing it with Davey. They have done work for both our trees. I'm very pleased with the gentleman I've been dealing with. They've come out here and given a lot of help, and they're real professional. I feel more comfortable having a Davey person out here working on my property. I'd give them an A+.”
“They did our house. They were very careful with their work. It was a big, big tree, so they really calculate the things first. I would give them an A+.”
“They were prompt and efficient, and they cleaned up as stated in their contract. They did the job that I expected and contracted to do—we were satisfied with everything. We had damage to a birch tree from a storm, so that tree had to be shaped up and balanced. Then, I had a couple of other trees pruned. I'd give them an A+.”
“The Davey Tree Expert Company did some tree trimming for me. The guy came to give the quote very quickly, and it was very simple. I think they showed up even a half an hour earlier than they were expected, and they got the work done. They did a great job of sort of cleaning up and taking everything away. There was a little bit of damage to something in the process, but they corrected it by the next day, so I was very happy. I give them an A+.”
“I liked the way that they cleaned up after themselves. They were pruning my trees in the back and in the front, so there were a lot of pieces that they had cut out of the trees, but they picked everything up and carted it off. They were very polite—very tidy in their work. I would say they're an A+. I plan on using them again.”
“They came when they said they were going to come, they cleaned up when they were done, and they did the work in a timely manner. They did a good job. I'd give Davey Tree an A.”
“I think they're professional, and they did the work professionally. They promptly responded to our request for consultation. They came on time, and they actually explained everything. They cut a large branch. They did a job for our neighbors, who we got positive feedback from. I would give them an A.”
“It's my first time using Davey Tree. They're not quite done with the work. They removed all the trees for me, but they have to grind up the stump that remains, and they also have some tree trimming to do. I knew of them from seeing them do work in the neighborhood previously and then through a neighbor I'd heard had a very positive experience using them. I'd give them an A.”
“They were on time and did what they said they were going to do. They did some pruning, and then they took down a big tree. I would give Davey an A.”

Davey Tree is terrific. They were on time and very professional. We're totally satisfied with them. They trimmed a maple tree in our backyard, and we liked the artistry of their work and their thoroughness and sense of purpose in doing their job. It was very creative and effective. They're an A+.

Davey Tree trimmed a very large poplar tree and holly tree. They also removed three clumps of wisteria, and they properly shaped several trees. The trees look excellent, and the cleanup was excellent. I would give them an A.
