They've been doing work for me for a long time. They designed a front entrance for me using stone, and they did hardscaping and landscaping with lighting. They do really good work. I'd give them an A+ for my overall experience.
I'm very happy with East Coast Landscape Design. They showed up on time, they did what we asked them to do, and they did a good, quality job. They did a small stone patio, and previously they built a nice stone wall for us. They're an A.
They were very professional, courteous, flexible, and helpful. They are a top-rate company, and I really enjoyed working with them. I'd definitely give East Coast Landscape an A.
I liked that they were thorough and that they did what they promised they would do. The job was completed in a timely manner, and I was very satisfied and happy. They're an A.
They didn't have quite what we were looking for, but they gave us an alternative, and it was better than what we were going to do. They did yard drainage. I'd give them an A because I thought it was very nicely done. It took a while to schedule it, but once it was scheduled, they were there. We've already recommended them. We've talked to different people when we showed them what they did, and we told them if you're interested, we have a guy.
They built a 12-foot-high, 40-foot-long retaining wall. They also did landscaping and paving. I liked that they were efficient. They did what they said they were going to do. I liked their completeness. I'd give them an A because have no complaints.
I liked the expertise they showed and the quality of the service. They did the job exactly the way we agreed upon. For example, the grass they put in has lasted through the winter and still looks good. They've done demolition and concrete replacement for the driveway and sidewalk and new front yard sod. I would give them an A+. I would recommend them to anybody, including family members.
He's been doing work for me for a long time. He designed a front entrance for me using stone, and then he did hardscaping and a whole bunch of landscaping around it with lighting. He does really good work. They get an A+ for our overall experience. He comes back every year and takes care of stuff.
I'm very happy with East Coast Landscape Design. They showed up on time, did what we asked them to, and did a good quality job. They did a small stone patio, and previously they built a nice stone wall for us. They're an A company.
I liked the fact that they were thorough and that basically, what they promised they would do, they did. I also liked that the job was completed in a timely manner.
