Cabin John Builders is a small-volume custom builder based in Cabin John, Maryland, serving the Washington, DC area and Chesapeake Bay. Its own site describes custom homes, whole-home renovations, additions, and one-of-a-kind structures, while Houzz shows 21 projects and a long service-area list.
Recent Google reviews from April 2026 repeatedly describe clear communication, reliable scheduling, staying on budget, and strong results on large renovations, patios, basements, and additions. A 2024 one-star review alleges repeated floods and poor interior work, so plumbing, heating, insulation, windows, and subcontractor oversight deserve direct questions before a major build.
The company is best suited to substantial custom homes and whole-home renovation or addition work. Confirm the current license status, who will handle specialty trades, and how comparable recent projects can be inspected before signing.

Sudden Death Of Cabin John Builder Billy Hendricks Leaves Community Reeling - AOLDec 16, 2025
“Billy Hendricks passed away Saturday morning, Dec. 13, after a sudden medical event, according to his longtime employers at Cabin John Builders in Montgomery County.”
Working with John and Neal was an absolute pleasure. They are kind, honest, knowledgable and considerate. We started our project feeling very well informed and the Cabin John team delivered. We met our timeline and budget, and the end result surpassed our expectations. Would use them again and recommend them in a heartbeat!
Couldn't recommend CJB more highly. We hired them for a complicated and large renovation, and they exceeded our expectations in every way. They were reliable, timely, honest, able to solve complex challenges, stayed on budget, delivered beautiful design work, and were a total pleasure to work with every step of the way. Top-notch professionals from start to finish and we couldn't be happier.
We had Cabin John builders help with two separate projects. First we were building an outdoor covered patio with fireplace. We had a prior builder who fell through at the last moment, and Josh and Neal at Cabin John builders agreed to work on our project and started quickly. We were so impressed by their professionalism and their ability to jump into our project so quickly. The end result was fantastic and we are so happy with our outdoor space. We were so happy with their work that we hired them for a master bedroom renovation two years later. Our renovation involved moving the shower from one end of the room to the other in place of a bathtub. They also worked to extend the closet that backed up to the bathroom by removing a linen closet. They recommended several vendors for both stone, vanity, and fixtures which worked really well. We loved our project manager and became very close with him throughout the project. Our space now is totally changed and we have a beautiful space we'll enjoy for years. I wouldn't hesitate to recommend Josh and Neal and their team at Cabin John.
Cabin John Builders has done three projects at our home and frankly they’re the only builders we would use. We bought our house originally in 2012 and they did a total remodel. We had ultimately left the basement unfinished during our original remodel because we didn’t know how we were going to use it and several years later they came back and finished off the basement. In 2018 we added a whole home addition and they did an absolutely phenomenal job. Josh, Neal and the entire crew are absolutely fantastic to work with and I knew what was going to happen and when it was going to happen, and I was also aware of all the costs associated with each one of the projects. I really don’t understand why you’d use anyone else for a major building or remodeling project at CBJ are absolutely the best.
