No more flooding! This September / October, they worked a huge project that involved creating landscape steps, more hard space with pavers, relocating our fire pit, and new landscaping. While the project took longer than planned, it turned out great. They have a top notch team and really care about their work. Wouldn't hesitate to offer a recommendation...which is why we keep returning to them! ### All 6 reviews **★★★★★ — Jennifer Romm, April 2020** > We worked with Blake to design and build our lovely garden. He is a visionary with no ego so extremely great to work with. It was an extensive project with tight deadlines that were strictly met. He developed the plans and made them a reality - with a keen eye to our budget. His attention to detail is impressive. We liked that he was both the architect and the builder. Now Dunlevy maintains the garden. It was one stop shopping. One person took full responsibility for all of the details. The Dunlevy team is hardworking, reliable, honest, polite and knowledgeable. Every interaction with them exceeds expectations. I could not be more pleased and we recommend them to you without the slightest reservation. **Comment from D. A. Dunlevy:** > Thanks Jennifer! It has been a delight working with you all! **★★★★★ — takemetothebeach, Jan. 2016** > We had D&A landscapers remove a tree from our yard. They were so professional and polite, they cleaned up, and the work was wonderful-every root was gone and the yard looked great. > We also had them install a cut flower garden. Their choices of flowers were perfect. I enjoyed the beautiful blossoms all summer long. > They also did our spring clean up, which entailed a massive cut back of all of our shrubs due to the extensive cold temperatures last year. Everything has grown back and filled into great looking plants. Now I'd trust them to do anything, they are great landscapers. **★★★★★ — lisastombaugh, Jan. 2016** > As the president of a homeowner association I am always looking for vendors that can do the work without issues and can provide us with an Assortment. A one stop shop. Someone that I can trust to do the job correctly without someone standing over them during the process or having to call them back for corrections. When you have many eyes on you all the time looking to complain like I do you don’t want to hire someone who has come up short and has not completed the work with care. I can say I have found my one stop shop. I call D&A for everything. I can call the office with a tree emergency and they will show up that day or the next to assess the situation and give me a quote so I can let the homeowners know that it will be taken care of in a timely manner. Which I love, they have done our drainage work as well as replaced and repaired our damaged sidewalks. I have never had to call them back with a complaint. It is very refreshing to have D&A on my side. I highly recommend them! **★★★★★ — pthambi, Oct. 2015** > Below is an email I sent to DA Dunlevy after the project was completed: > > "Things look great and the team that worked on the project was very professional and paid attention to the details. Please let them know how impressed we were with them. > > Also, the process, from meeting with you and Blake, the design, and implementation were done very well. I found everyone to be honest and this is important to us. Based on our past experience, we have found this is not a common quality among contractors. > > Everyone was also responsive to the few issues that arose." > > Will plan on working with them again for any of our future landscaping needs. **★★★★★ — williamprice, Sept. 2014** > D & A Dunlevy worked on our basement installing drains and new steps. We were very pleased with the work, they were neat, and on time. We would gladly work with them again. ## Selected projects - [A French Countryside Retreat in Bethesda](https://www.houzz.com/hznb/projects/a-french-countryside-retreat-in-bethesda-pj-vj~7701481) - Location: Bethesda, MD - Photos: 21 - [Where Old Charm Meets Modern Elegance](https://www.houzz.com/hznb/projects/where-old-charm-meets-modern-elegance-pj-vj~7701471) - Location: Frederick, MD - Photos: 13 - [A Modern Oasis of Function & Style](https://www.houzz.com/hznb/projects/a-modern-oasis-of-function-and-style-pj-vj~7701459) - Location: Not specified - Photos: 14 - [A Sumptuous Backyard Design](https://www.houzz.com/hznb/projects/a-sumptuous-backyard-design-pj-vj~7701442) - Location: Bethesda, MD - Photos: 15 - [Serene Garden Sanctuary](https://www.houzz.com/hznb/projects/serene-garden-sanctuary-pj-vj~6714770) - Location: Washington, DC - Photos: 13 - [Olde Washington Heritage](https://www.houzz.com/hznb/projects/olde-washington-heritage-pj-vj~7223390) - Location: Chevy Chase, MD - Photos: 13 - [A Modern Retreat](https://www.houzz.com/hznb/projects/a-modern-retreat-pj-vj~7223405) - Location: New Market, MD - Photos: 14 - [Sea La Vie](https://www.houzz.com/hznb/projects/sea-la-vie-pj-vj~7043426) - Location: Woodbine, MD - Photos: 18 - [Kinship & Reciprocity with Nature](https://www.houzz.com/hznb/projects/kinship-and-reciprocity-with-nature-pj-vj~7043417) - Location: Poolesville, MD - Photos: 14 - [Historical Upgrade](https://www.houzz.com/hznb/projects/historical-upgrade-pj-vj~7031738) - Location: Frederick, MD - Photos: 14 - [A Backyard Destination Made Just in Time](https://www.houzz.com/hznb/projects/a-backyard-destination-made-just-in-time-pj-vj~7025297) - Location: Bethesda, MD - Photos: 21 - [Dolce Far Niente](https://www.houzz.com/hznb/projects/dolce-far-niente-pj-vj~7025250) - Location: Glen Echo, MD - Photos: 22 - [Water-Lovers Paradise](https://www.houzz.com/hznb/projects/water-lovers-paradise-pj-vj~7025224) - Location: Washington, DC - Photos: 13 - [The Luxury of Balance](https://www.houzz.com/hznb/projects/the-luxury-of-balance-pj-vj~7025161) - Location: Mount Airy, MD - Photos: 10 - [Stylish Whimsy](https://www.houzz.com/hznb/projects/stylish-whimsy-pj-vj~6830789) - Location: Chevy Chase, MD - Photos: 14 - [Innovation Meets Elegance](https://www.houzz.com/hznb/projects/innovation-meets-elegance-pj-vj~6830781) - Location: Bethesda, MD - Photos: 13 - [A Verdant Courtyard](https://www.houzz.com/hznb/projects/a-verdant-courtyard-pj-vj~6719449) - Location: Washington, DC - Photos: 11 - [Modern Meets Classical](https://www.houzz.com/hznb/projects/modern-meets-classical-pj-vj~6719444) - Location: Washington, DC - Photos: 13 - [A Luxurious Addition](https://www.houzz.com/hznb/projects/a-luxurious-addition-pj-vj~6719437) - Location: Washington, DC - Photos: 13 - [Beautifully Intelligent Design](https://www.houzz.com/hznb/projects/beautifully-intelligent-design-pj-vj~6719434) - Location: Washington, DC - Photos: 10 [See all 34 projects](https://www.houzz.com/professionals/landscape-architects-and-landscape-designers/d-a-dunlevy-pfvwus-pf~1703656905) ## Video - [Company video](https://player.vimeo.com/external/851358868.m3u8?s=e3b9355766ca829c2f00845c805e7c5dd6da48d6&oauth2_token_id=1384357804) ## Community Q&A **Q: How far is this pool from the house?** *(in Photo Questions)* Trying to plan pool placement for large open back yard A: Hi! This pool is approx. 50-60' from the back of the home. Thank you, Evan Moreland Marketing Coordinator **Q: Plaster color?** *(in Photo Questions)* Do you know what color the plaster finish is? A: It is Bella Blue Pebble Fina. **Q: What are the 7 trees that create the privacy?** *(in Photo Questions)* A: Those are Nellie Stevens Holly trees. These trees are not only great for creating privacy screens, but are also low maintenance as they will keep a uniform shape as they grow (no pruning!). **Q: decking** *(in Photo Questions)* Hi - can you share info on the decking? Is it concrete with pavers? A: The pictured pool decking is exposed aggregate (a type of decorative concrete) with Pennsylvania flagstone border and banding. This is a great example of combining beauty with function as the exposed aggregate provides a non-slip surface while the flagstone adds a pop of color. **Q: What is underneath the japanese maple?** *(in Photo Questions)* Are there azaleas underneath the japanese maple? A: Hi Jennifer - While those plants look like azaleas at first glance, those are actually Knockout roses without any flowers in bloom yet. The red parts on the tips of the branches are new plant growth that will later turn green. Thanks for reaching out! **Q: Crepe myrtle** *(in Photo Questions)* The crepe myrtles look beautiful around this patio in this photo. What type can handle exposure in zone 6? Thank you A: Hi Lovit - Thanks for reaching out! It's a pretty interesting answer, actually. The crape myrtle that have Native American names tend to be more cold hardy. These include: Natchez, Hopi, Muskogee, Tuskegee, etc. Any of these of would be a great choice for planting in zone 6. --- *Source: Houzz professional profile. Reflects the profile as of 2026-09-08.*
