“The quality of the work is always great. I've been using them for a long time. They did a hardscaping/landscaping project for me several years ago, and now they maintain it on an annual basis. It's always good. I get a lot of compliments about the work. I have a lot of people, even delivery people—everybody loves the work they did. It's really beautiful. I highly recommend them. I'd give them an A for sure.”

“They've done work for me for 25 years. I like how they de-bed. Their de-beds are the top in the world; it's just beautiful. They let you be a part of the decisions. They're just nice people to work with. They come and do their job, and when they leave, it looks like a beautiful thing has happened. They've done landscaping. I have a slope in my backyard, and they landscaped the whole slope and put stone steps going up to a park behind my house. They just did this trench for my guest fireplace—beautiful job. They're an A+ all the way. They did this little trench, and the edges were as straight as their de-bedding. I've never seen a trench quite this nice.”

“It was excellent. I will definitely recommend them to anyone. They work on schedule. They were right on target. They finished on time, and that's where it stays. I really liked that. They did paving. They paved my new driveway. They get an A.”

“They were very good, on time, and very neat about everything that they did. They were very good at planning. They've done pavers before, but they just did landscaping this time. I'd give them an A+.”

“We were very satisfied. They were very professional, on-time, friendly, and dependable. We were very satisfied. They did landscaping, paver, and then they also steered us to a gentleman who did a deck remodel and a pergola. East Coast deserves an A.”

“I think they were timely. If I had any concerns, they responded to them very quickly, which I liked. They gave me a lot of follow-up and care. They also have a quarterly newsletter they give out to their past clients, and they update you on what you should be doing this year—what to plant and things like that. They did some hardscapes too. They built a small retaining wall and extended a concrete sidewalk. I'd give East Coast Landscape Design an A.”

“The work they've done so far has been satisfactory. They did, principally, landscaping at my house in Washington. I've had no complaints, and I would recommend them.”

“I liked everything about East Coast Landscape. They did good, quality work, and they were nice people. I'd give them an A for my overall experience.”

“The owner is very honest and open, and he has a great reputation. They deliver very high-quality work, and they work well as a team. The last project they did was some grass, some beds, and the patio. I would give them an A+. I recommend them highly.”

“We love the design. I think they have a very good designer. They did landscaping for us. The workers were great, and they did a great job.”

“They landscaped under my deck, and they did erosion control. They were very personable, they answered all of my questions, and they were interested in doing the job. I would grade them as an A. I would definitely recommend them.”

“I've worked with Mark, the owner, before. He is very honest and open—great reputation. They deliver very quality work, and they work well as a team as they promise. The last project that he did for me was light landscaping, patio, and some sod work for us. They put in some grass, then some beds, and then put in the patio. I would grade them an A+. I recommend them highly.”

“I think they have a great designer. We love the design. They did landscaping for us. It took them a long time to finish the project, but the workers were great and did a great job. I'd give them A- for my overall experience.”

“They did what they said they were going to do, and it looks good when they are done. They added landscaping, low plants, and a tree to two sides of the house. They get an A+.”

“I'd rate them A. They were very personable, answered questions, and were interested in doing the job. They landscaped under my deck, water shed, and did erosion control. I would definitely recommend them.”

“They did a good job with the landscaping, and they were very responsive. I would grade them an A-.”

“I'd rate them an A.”

“They listened, and they tailored their recommendations to me. They were on time and on budget. They did hardscape and landscaping for me. I would grade them an A.”

“I liked everything about them. They did good quality work, and they were nice people. I'd give them an A for my overall experience with them.”

“I liked them. They were very professional and did the job I asked them to do. They were an A.”

“I liked quite a number of things. Some of the important things were timeliness, efficiency, and speed. These were the most notable things that I saw immediately when they started the work. They did the landscaping on my lawn. My basement was dripping water—it was seeping through the wall. We thought it was something to do with the wall. They said it was the landscaping, and that was precisely what it was. I wanted to test it through everything to make sure that it holds, and it has held. I would recommend the company. I've recommended them to friends. I've been speaking to them, and I have been to the office. They are conscientious and very professionally minded. When they get started on the work, they don't stop until they finish it. If they say that it will take three days, that's exactly what will happen. They're A+.”

“They did what they said, they did it on time, and they did it in budget. They were refurbishing a pondless water field. I found them from a referral. I would give them an A+.”

“They were creative. The job was landscaping. It's not something that everyone is familiar with—we didn't know which kind of plants would be deer resistant and that sort of thing. They knew their plants. They knew which ones would grow in what kind of area. They also had to come up with a solution for the bank where the water was running toward the house instead of away from the house. They fixed that very easily. They showed up on time, and I think they deserve an A.”

“I liked interacting with the owner, and they promised what they delivered on time. They did some landscaping. They put in some stepping stones and some plants along a sloped part of my property. I would recommend the company. I would rate them as an A.”

“They're reliable. They've been doing work for us for a long time. They're fine. I don't have anything to complain about. They had come out to do maintenance. I've been using them for about five years. I would recommend the company.”

“They came when they were supposed to come, they did what they were supposed to do, and the price was what they quoted. They did some tree and shrub trimming for us. I thought the work was an A.”

“East Coast Landscape Design does a really excellent, very professional job. They edged and cleaned up everything really nicely—it's beautiful. They're really knowledgeable about plants. They gave me a lot of good ideas for plants that are deer resistant, which has worked out fabulously well because we have tons of deer. They're very nice people, and their plan looks very nice. I would absolutely give them an A+.”

“They're fantastic. They're getting bigger, but the owner still comes by to talk with us and make sure things are going well. Our lawn looks great. I would definitely rate them as an A.”

“East Coast Landscape Design is very professional, the work is above par, and they're a great group of people to work with. They completely landscaped the entire backyard. I've been using them for about three years. They're a grade-A company.”

“I liked everything about the work, and East Coast Landscape knew what they were talking about. They showed up on time, and it's worked out well so far. I tried them, and things worked out. I got an estimate from somebody else, but East Coast Landscape seemed like the best fit for what I needed. I'd probably give them an A.”

“I would give East Coast Landscape Design an A rating because they were great.”

“East Coast Landscape did some work for me, and I was satisfied. They get an A.”

“East Coast Landscape Design really took their time and did a nice job. They did landscaping for my home. I'd rate them as an A.”

“East Coast Landscape did a very good job, and they were on time. I had hired them before a long time ago, so this was their second time doing work for me. I would give them an A.”

“I called East Coast Landscape for my landscaping needs because I got a referral from a neighbor. I would refer them, too, and I would give them an A- grade.”

“I liked East Coast Landscape Design. They did hardscape and landscape work. They were professional and courteous, and they answered all my questions. They did a good job—they did what they said they were going to do. I would give them an A.”

“There used to be brick everywhere, and we had a deck that was awful. East Coast Landscape totally redid the backyard. They regraded the yard, put in grass, put in plants, and put in a paved patio. They were great.”

“The lead guy from East Coast Landscape was amazing. He did the hardscaping, and he was just really great. They're an A+.”

“East Coast Landscape did our walkway in the front of our house, and then we used them again for the back patio. I'd give them an A+.”

“I use East Coast Landscape. We've been using them since we bought the house last June. They gave me a good referral for my sprinkler system. I would give them an A+.”

“I had a positive experience. They were a one-stop shop and very professional. They landscaped my backyard, including a patio. I give them an A.”

“Very good service. They did everything very nicely. They came to plant some bushes and put mulch in, and the whole yard looked very nice when they left. Five or six years ago, they did the whole yard, and this time they just did one side of it because some bushes had died, so they came and replaced them. Because they did such a good job the first time, I called them back. They get an A.”

“East Coast Landscape was recommended by a construction company that I used. They did some planting, and they were very receptive to suggestions. They were very competent and very easy to work with. I would recommend East Coast Landscape and give them an A.”

“It was absolutely a positive experience. The owner came out and discussed the work, and I found him to be a very professional person. The company's very reliable. The workers who came were very professional. There was good communication with the guy in charge, and I really like that. They did exactly what we had asked them to do. They didn't work on the lawn. We're pretty much do-it -yourselfers as far as our landscaping goes, but there was just a lot of spring cleaning up that we needed because it was just too much for us to handle at this point. So they did a lot of cleaning up of yard debris, cutting back, and then they did a lot of sculpting of landscape beds—re-sculpting, mulching, and weeding. They made everything look just, you know, tidy and clean for the year. There were no surprises, and the yard looked very, very nice afterward. Then the person in charge of the work even said to get back in touch with him if there was anything else we wanted him to do or if we weren't satisfied—if things needed to be corrected or whatever. So it was a very, very good experience. I haven't had to get back in touch with him for any reason. I'd definitely give them an A.”

“They're finished for the most part. They still have a couple of trees to plant, but those aren't coming in until October. Ninety-eight percent of the work is done. We basically re-landscaped the front yard and put some hardscape in. I work in the same area where the company's from, and I just noticed them one day on the way to work. Then I had Mark out to talk and just thought he would be someone that I could trust in getting done what I needed to have done. I would say they get an A-. We had a minor communication issue but nothing that was a problem. They stood up to everything they told me and made everything right. I've got no issues with them, and I'll use them again. I give them an A-.”

“East Coast Landscape Design was excellent—terrific. They laid it out nicely, and the design was nicer than what we could've come up with. They did work for us ten years ago, and it was really beautiful, so we called them back. I'd definitely recommend them—they're an A+.”

“East Coast Landscape Design removed some overgrown bushes, filled in a pond, and installed a stone patio for me. They also trimmed some trees and corrected an erosion problem I had. The crew had a very artistic flair and attention to detail. I was very pleased with the results. I would give them an A+.”

“East Coast Landscape Design landscaped my backyard and front yard for my brand-new house. It was beautiful, and they were very respectful of both me and my property when they came out. They left it immaculate. Everything was picture perfect.”

“My experience with East Coast Landscape was very positive. We had them do work on our house twice. People should definitely consider them for any project regarding stone work or landscaping. The work they do is very, very detailed and looks very good. They are true artisans. I would recommend them to someone else in a heartbeat.”

“East Coast Landscape was fantastic. They refurbished a pond for me, and the quality of work was excellent. The technicians were personable and artistic. Everything about the company is quality, and they stand behind their work. They’re an excellent, excellent company—A+ on everything.”

“We had East Coast do the landscaping in our backyard. They installed a water feature—a fountain—and lighting. They also built an area around the fountain with shrubs and trees. All their guys are very conscientious. It’s a great company—A+.”

“They landscaped my entire waterfront property. They did all the rocks, all the drain tiles, retaining walls—pretty much everything that’s in my yard. I was absolutely pleased with everything they did. They had their own architect that did the drawings for me. They were excellent.”

“I thought East Coast Landscape Design was great. They were good in all areas, and they had a wonderful, integrated approach. They integrated the patio and the drainage. They did a fabulous job.”

“They did very good work for me. We redid all of our landscaping. They also built a new paver patio with steps and a brick retaining wall. They did a good job all around. I would use them for any landscaping work.”

“They built a patio and a retaining wall. They did some big work for me. I think they did a good job. No problems. I would refer this company to a friend—I don't have any hesitations.”

“They did the original landscaping. Everything was done very expertly. No complaints or concerns about anything with the company, none whatsoever. I'll absolutely use them again.”

“They built a pond, and they cleaned up the pond. They keep up the maintenance on it as well. Everything was satisfactory with the work they did. I'm enjoying the pond. No complaints or concerns whatsoever.”

“They did hardscaping on our deck and terrace area, in the back of the house. I was happy with the way everything turned out. They actually finished early. It was nice. They were very professional about cleaning our yard. They were great. I would absolutely recommend them.”

“We had some bushes, trees, and cypresses that needed to be trimmed and manicured, and we have about six of them. They were irregular based on where they were in the sun—some were taller, some were shorter, some were bushier—and they trimmed them down and made them look perfect. We were happy with the services. They staked them, too, since they were subject to wind. That was partially why we had to have them come; it was a couple of winters ago when we had all the snow, and one of them fell over. I would use them again. There were no surprises.”

“They did a small tree job for me, but they're our landscaping company. They cut down a dead tree. The time frame that the work was finished was fine, and the cleanup was fine. I'd do an A.”

“Everything went well. They completely landscaped the front and the back of the house and put in some hardscape. I haven't had to call them back to fix anything. The plants are guaranteed for a year, so I may have to call them back, but every time I've called, they've been very responsive. I'd give them an A.”

“East Coast Landscape was very quick to respond, very quick to quote, and very quick to actually get the job done. Their quality of work was very good. The time frame in which the work was finished was very good. They landscaped our front yard and put grass seed down in the front yard. I thought the cleanup was excellent. I did not encounter any negative experiences with their services. I would give them an A.”

“They did a pretty small job in my backyard—it was a little circle patio that they did. They did OK, no issues. I would use them again.”

“East Coast did some landscaping for me in the last three years. We are satisfied with their service. They put in a walkway for us, and they gave us nicer steps than what we had. They did a good job with the work.”

“They did landscaping work. The help was really good; they did a good job. They did really good work. They cleaned up after themselves. I would recommend them to others.”

“East Coast Landscape Design did some work for me. It was good. I call them when I want them. They clean up well after their services. They're wonderful. They are very professional. Mark is a wonderful guy.”

“They did a whole bunch of landscaping, a lot of planting, some pond work, and waterfall work. They've done quite a bunch. I would use the company again.”

“They put a pond in my backyard. They did good-quality work. They did it while I was at work. They finished it in a good time frame for me.”

“I was happy with the work. They did just landscaping. I am happy with the workers. They were fine. They were great. I would use them, but I have moved.”

“They did landscaping at our house. They landscaped the whole front of our house. We didn't know much about it, so they were really helpful. We're not really landscape oriented. They gave us some general ideas, and they were able to turn it into a design that was exactly what we wanted. It's low maintenance; it looks good, and it has stayed that way.”

“They did a professional job. They did landscaping for us. It wasn't an extensive job. The workers were very professional. The cleanup was very good. I'd recommend them. I saw some things they still need to do, but I talked with them, and we're on the road to getting it done. Give them an A.”

“They did a great job.”

“Last fall, they did some sod work and some planting for us. They've done a lot of work for us over the years. They graded our lawn so we wouldn't get water in the basement. They've planted trees for us. Mark comes out personally and makes recommendations for landscaping and so forth. We trust him, and we like him. He's very pleasant to work with.”

“East Coast Landscape Design did nice work.”

“They did some landscaping work for me over the last year or two. I thought they were quite good. They basically replaced a stone patio in the back of our house, which had been badly installed in the first place about 12 years ago, and they replaced flagstone patio that involved pulling up all the old stones, putting the correct base down, and then replacing it with new stones. They did a really good job. They did the job in a timely manner. They cleaned up well after their service. I would probably give them an A rating.”

“They did some design work. I thought the quality of their work was good. I would refer this company—I already have.”

“They did some landscaping work for me in the last four years. I thought they were excellent. They did dry stack and terracing of sort of a garden area on the end of the house, and then they dug out under a deck and placed pavers and a small retaining wall underneath our deck so we didn't have a mud hole under there anymore.”

“They have built a retaining wall and some steps. Satisfactory job—I think it was quality work. Nothing stood out about the company. I'd never worked with them before. The wall and the staircase and everything that they did for me, it's everything I wanted and is serving the purpose, and is holding up well. I will call on them again if I have a need.”

“They did a good job for me. Our backyard was kind of a disaster, and I had various people come and take a look and give us some ideas, and we chose East Coast to do it. They replaced everything that didn't make it, and we had them do some other things as well. They showed up on time for their appointment.”

“East Coast Landscape Design did a good job.”

“They did work for us over the last 20 years. They helped fixed up the house I was getting ready to sell. All I can say is that after the first time I used them, I used them again every year for 20 years. I don't know if I can say anything better than that. They're very professional. They have an experienced crew. Many of the same people show up year after year, and if there's something that's not exactly the way I want it, then they fix it.”

“They did a brick walkway. It looks beautiful. They did shrubs and bushes as well. I was very satisfied with the service. They were polite and professional when they came out. I would recommend them to other people.”

“I contacted them last year to get some work done. I would give them a good report. They have done work for me twice. What is most memorable about working with them is once they started the work, they finished it. There was a question about one of the trees that needed to be replaced, and they took care of it. I have nothing bad to say about them. Never any concerns with customer service—they were responsive. They clean up after themselves—when they leave it looks great. I would recommend East Coast to others, and I have.”

“Excellent work. The guys, they're great. They've done both hardscape and planting shrubs. I would recommend them to other people.”

“The bottom line is, they do great work. They are fantastic, and that's really all I can say.”

“East Coast filled in a driveway for me with no issues. It was done on time. I have no issues with the work done. What was most memorable to me about using them was, again, they were very professional. I was happy with the work performed. They cleaned up afterwards. I would recommend them to others.”

“We've had a contract with them for multiple years. They're there, they do it. I feel it's good-quality work. The lawn looks good. No issues with the workers who come out. They do an excellent job. They're good with follow-up. The nature of the business, we don't really have appointments. You sign on for a year, and they come out when it's time to do it. They do excellent work. I have recommended them to others.”

“They were really, really good. I've gotten so many compliments on my driveway. They were great.”

“They did a yard makeover with some retaining walls, some local plants, and plantings in the front and the side of the house. I was happy with the work that was done. I really enjoyed working with Mark. Very professional workers.”

“They do lawn service and landscaping, and they resodded and put in plants. It was, I think, an excellent job. But that was compared to what was there before. I am happy with the way it looks, definitely. They did a very good job.”

“They're a really good company. They had to do a little drain in my side yard to take water away from the house.”

“They helped redesign a pond that we have in our yard. It's really cool. It looks really natural. They got it done in a reasonable amount of time. I would use them again. I would recommend this company to other people.”

“I use East Coast. They do treatments. They do excellent work. There is a noticeable difference, for the better.”

“My lawn care is done by them. They do feeding and treatment. I'm happy with them. They show up on a periodic basis to do their thing. They leave the bill and a little thing in the yard saying, 'Don't get in the yard.' I'll continue to use them.”

“They do treatments. They're very good. I would grade them an A.”

“The lawn service I've been using is East Coast Landscape Design. They don't do mowing, but they do fertilizer. I've been using them for about a year. I notice a difference.”

“We have East Coast. We love them. Ralph, who comes to our house to put the fertilizer down, pays personal attention to the lawn. He takes the time to get to know our specific issues and actually seems to care about my lawn. He takes professional pride in it, which you don't see very often.”

“For the fertilizing, I use East Coast Landscape. They're very good.”

“They do the fertilization. They do a good job.”

“They did some landscaping services for me over the last year or two. I thought it was really good—really well designed, well implemented. There was good follow-up from the owner, Mark. All in all, I was pleased. We've got a little bit more work to do, and we'll likely call them again.”
