Hello. Mark did a great job on our patio a few years ago. We're in a new house now and looking to add a screen room over a small patio.

ECLD listened to the ideas I had for my yards and helped me turn them into projects that met my goals for function, beauty, and privacy and they did it within the price range I wanted. The quality of the plants and materials they used was very good and nearly all thrived during the growing season. I had one tree that mysteriously browned and died, so they replaced it (no charge). Also, when they erred during the planting of some groundcover (they put it slightly in the wrong place) they fixed it the next day. They were easy to work with, professional, and are clearly very interested in working with you to get you what you want.

Erosion Control

This was a large erosion control and slope stabilization project. I am very happy with the resulting retaining wall, multi-level patio, safety railing and the rocks and plantings that were used to fill in the eroded area of my property. I wanted the erosion control and retaining wall. I got those and more. I have a beautiful, functional outdoor living space. The expert crew had a good eye for the aesthetic aspect of the design on top of their technical construction knowledge. They protected my existing lawn so that it survived multiple bobcat trips carrying loads of block, rock and fill. I highly recommend this company.

I have been a customer of East Coast Landscape for 25+ years. The company has landscaped my entire yard with great results. I would not use anyone else.

There is always an open line of communication with the owner and those who come to the work. These people show respect and are knowledgeable about what they are sent to do to my yard.

East Coast Landscape is a great company.

Precision Stone Work

We hired East Coast to install lighted flagstone steps and a rather long path to our house.. The job required regrading and precision stone work. They did a beautiful job, were responsive to requests for changes, and completed the work in time. I highly recommend them.

It Was Excellent!

It was excellent!!!!! The only thing that took the project 2 weeks longer was the DCRA inspection process which DC reaidence know is a head ache in itself. We are hiring them again to do our patio and firepit along with another time to do our walkway to the front door and porch. Excellent company service and employees. Worth every penny knowing they did a solid job that will not ever fail when completed.

Description of work:

We had our driveway redone with permeable pavers and the garage refloored with non permeable pavers along with 2 new walls built bordering the driveway with stone.

East Coast Is The Best!!

We just want to thank you for your wonderful response to our question about the sick/dying plant. Mark left me a phone message yesterday and the plant has been replaced and looks great. Please let Mark know how much we appreciate the terrific service. East Coast is the best!!

Very Pleased With East Coast

We could not be more pleased with every aspect of the project. There are not many Mark Simpson's out there! His breadth of knowledge, genuine interest and responsiveness made the project a pleasure. We kept changing our mind about the project. Mark would come to the house and have a new plan drawn up within a few days. Unlike some owners, during and after the project Mark stayed in close contact. The gentlemen who completed the project were also very knowledgeable, very competent and worked incredibly hard. They even suggested a slight change in the design of the wall which turned out to be a great idea. Overall, we are very pleased with East Coast Landscaping. We plan to continue working with Mark for additional post-project landscaping.

Description of work:

We have a significantly sloped, large backyard that has suffered constant erosion over the past 30 years. East Coast constructed an 8 foot high wall, then back filled, and then sodded what is now a wonderful back yard.


Absolutely Thrilled!

I received Mark's voicemail yesterday and wanted to get back to you to say that we are absolutely THRILLED with the work that was done on our patio. It is such a huge improvement and allows us to really enjoy our backyard now. And I can't even say enough about the professionalism of the crew. We will definitely call you again when we are ready to upgrade our front walkway.

Thank you very much.


You Guys Were Great!

Just a quick shout out to you and especially, Roberto, for taking on this project and getting it done, and done well. Here's to the 10 ( or 5) percent that can actually do what they say! I know Roberto and the guys are out there humping once more through this heat - god bless 'em.

You guys were great.

Cheers, best of luck with all your projects!

Impressed With The Artistry!

I like many others often complain that no one takes pride in their work product anymore. That is why I was so incredibly impressed with Roberto , who regraded and redid our backyard patio to improve water drainage.

Roberto is a perfectionist who obviously takes great pride in his work. In fact, our patio now looks better than when it was first installed. We were so impressed with his artistry. He is a master in his profession.

Hardscape & Landscape Plan

Mark developed a hardscape and landscape plan for us and was very responsive to our ideas and suggestions. His estimate was competitive with or lower than others we received, and once we were ready to begin work, he was able to schedule us within two weeks. His team was prompt, professional, courteous, and worked hard, long hours. They finished extensive hardscaping, including a retaining wall, in a matter of days, and always left the worksite tidy. Neighbors constantly mentioned how impressed they were. Pavers, bed building, and tree planting came next and was similarly done in an efficient and professional way. They provided same-day responses to any concerns we raised. Can't recommend this team highly enough!

Incredibly Hardworking, and Also Prompt, Professional, and Courteous

We've had a lot of work done at our house, and Mark and his team have been by far the most impressive. Mark worked with us to develop landscaping and hardscaping plans, and waited patiently while we decided what to do. Once we committed, he was able to schedule us within two weeks, even during the busy season. His hardscaping team was incredibly hardworking, and also prompt, professional, and courteous. They finished what could have been a multi-week job in a matter of days. The landscaping team was also great. Mark responded to our questions and concerns same-day. We've been so pleased with the final results and get compliments from our neighbors daily!

Would Definitely Hire Again

Managed to stay on time and on budget all while we lasted through the wettest spring and summer on record. Mark runs a tight ship and his crew is clean, courteous, and professional. Would definitely hire again.

Expertise Was Superlative

We contacted East Coast Landscaping after other contractors did a poor job with a retaining wall. They came in, gave a quotation, and came up with a good design, worked with available materials and budget. Their pricing was competitive, but their expertise was superlative. I would highly recommend for hardscaping projects.

Front Yard Is Transformed Into A Beautiful Space

The main reason for me to choose East Coast Landscape Design among all other companies I interviewed is their ability to understand my vision for a front yard makeover and to provide good suggestions for my design concerns. They beautifully executed the planned design with skillful workers who finished the job timely and professionally. Thanks for their craftsmanship and professionalism, my front yard is transformed into a beautiful space.

Impressed With The Quality, Punctuality, and Professionalism

So far, we are very happy with the work that Roberto's crew did on our patio/retaining wall. Blades of fresh grass are now poking up through the straw. The soil at the base of the wall if still very soft, but I expect it will settle. I am hopeful that from now on the maintenance and management of the patio will be much easier, and cleaner.

I was quite impressed with the quality, punctuality, and professionalism of your crew, and I'm so far quite pleased with the result.

Very Hard Working, and Professional

Mark came out as scheduled we talked over several options. A couple of days later I had a est. and start dates. The crew showed on time and completed the job on time. Mark is great he really knows his business. The crew was very hard working, and professional. At the end of each day they cleaned up the site. East Coast Landscape Design has a great team. Try them.

They did a retaining wall. It's perfect. They showed up when they said they were going to and finished the job up nicely. I hadn't worked with them before...I have some jobs in the works, and I plan on reusing them...I would call on them again...
