The Best Home Builder in Northern Virginia

After moving into our home, we did a series of renovations (kitchen, bathrooms, finished basement) before building a two-story addition. We encountered Ridgeline when we were searching for a builder for the addition and our only regret is that we didn't meet them sooner. I wish they had done all of the renovations in our house! Working with them was such a smooth process...

I'm an architect in the DMV. We recently met Ridgeline on an extensive home addition/renovation project. I was impressed with their professionalism and thoughtfulness. They are attuned to the details of construction, focused on project success, and experienced in local rules and regs. I look forward to our next project with Ridgeline Contractors.

Malcolm and his team are Ridgeline are the best contractors we have ever worked with period. In late May of 2024 we had a severe water leak that damaged our primary bathroom, kitchen, laundry room (basement) and basement bathroom. To be blunt - our insurance tried to low ball us on damages. Malcolm personally handled our insurance claim....

My first time using this company. They were polite and professional and flexible to send their tech out very soon after my request. I appreciate their tech's ability to quickly diagnose and address our concerns related to a residential house structure and air flow. This is a great company when you can't figure out who to call for unusual residential issues. Hope to work with them again. Thanks!

Malcolm, Jose, and the team rescued our DC rowhome after water intrusion significantly damaged our 3 primary floors + english basement.

Malcolm, Jessy, Tony, and the whole Ridgeline team were great! We had a very challenging design for an entire bathroom remodel, and they provided great feedback and were able to roll with it when the design failed to account for practical use. They were very quick to respond when problems inevitably arose, and made sure that everything was working exactly the way we wanted....

Malcom and his team are great! They get the job done quickly. They changed some flooring, painted the entire house, completely refinished the basement and laundry room, and made amazing custom closets. Malcom is super easy to work with and great communicator!

Ridgeline did an amazing job on our HOA project. Not only did the crew perform great work, but everyone was timely, and considerate. Malcolm communicated every day and was proactive in managing the project. He reviewed all work, stopped by daily for updates, revised the punch list as needed, redid work as necessary and left a thoroughly finished product. This was one of the easiest renovation projects to manage. Would definitely use Ridgeline again.

The Ridgeline team did an amazing job bringing my project to life. I had a boring room from the 70s that needed a facelift. The team helped me redesign the room around the fireplace by adding in built in shelving which was complemented by millwork, crown molding, shoe flooring, and a fresh coat of paint. I couldn’t be happier with the new modern look!! Can’t wait to hosts guests in my new room. Thank you guys!

Malcolm and his crew did an incredible job fixing an emergency ceiling repair at my home. I had received his contact information as a reference from a friend who was highly satisfied with his work in their home. He immediately scheduled someone to come out and get started on the patch, knowing I had family visiting later in the week. He went above and beyond to ensure the work was completed in two days, just hours before my family arrived.

I used Ridgeline to repurpose an old dining room into a living room. These guys were amazing. They built me a custom cabinet for a built in TV to redesign the room lay out. The custom woodwork was unmatched to anything else I've done at my house. The work was done quickly and at a good value. Ridgeline ensured I was 100% satisfied. I couldn't ask for more.
