I cant express how happy I am with the work Capital Builders that did on our house. David and his crew stepped into a nightmare when we discovered dry rot and termite damage to the back of our house of a scope we could not have foreseen. It was definitely nerve racking to face not only the initial damage we found out about, but how extensive it became. David was sensitive to how he communicated bad news to us as he kept us informed. Since the scope of the work was unknown, David charged man-hours instead of a flat rate which made sense due to the nature of this job. It was very difficult, though

The project delivery was excellent. David under-promised and over-delivered. His crew was punctual, efficient and very courteous. The final product exceeded expectations. The Capital Builders team helped us out with several exterior improvement projects we had been struggling to complete, let alone, start. His team did work in 5 days that would have taken me 6 months (on top of the 2 years I've been sitting on them). Being in the construction industry myself, it was difficult for me to accept hiring an outfit to come in to do work that I can (theoretically) do myself (but not as well). But after

Capital builders has been amazing more than once. They have been responsible, respectful and diligent. They did a downstairs remodel and it was great. I will continue to use them and refer them to friends, family and anyone looking for a professional team.
