EXCELLENT Based on 51 reviews Alyssa Gallagher2025-07-22Trustindex verifies that the original source of the review is Google. We hired Dan at DMB Builders for a full remodel of our 3-bedroom, 2.5-bath townhouse—and we couldn’t be happier with the results! The project was completed ahead of schedule and on budget, which is practically unheard of. Dan’s attention to detail, professionalism, and organization were outstanding. Since we weren’t local during construction, communication was critical—and Dan delivered. He kept us in the loop with regular texts/photos, phone calls, and updates. We always felt informed and confident in his work. Dan exceeded our expectations in every way. We’ll absolutely work with him and his crew again. My only hesitation in writing this review is that he might get too busy for our next project! Joe Mason Joey2025-01-21Trustindex verifies that the original source of the review is Google.

We are more than thrilled with our kitchen/family room remodel completed by dmb builders. After interviewing several other contractors who simply wanted to rip out old and install new, it was a real pleasure to find that Dan was willing to work with us within our budget. He has a good eye for design and is an efficient project manager. He promised and delivered a 4 week timeframe. His team is wonderful to work with kept the project site clean every day. We will definitely use dmb builders for our next project! Rory Driskell2024-07-03Trustindex verifies that the original source of the review is Google.

Really fine work and fair pricing. They will do all my home improvement projects from here on out. Kayla Kremer-Holzschuh2024-06-10Trustindex verifies that the original source of the review is Google. Contacted Dan because I was unsatisfied with another, bigger contracting company in Carlsbad who did our drawings and permits. A few things he does far better than any other contractors we contacted (we received quotes from several, big to small): - Dan and DMB work on smaller batches of projects at a time making you feel like the top priority. The bigger contractors made me feel like just another number in the queue. - He's has very high integrity and strong communication. If you have a problem, he hears you out on your concerns and works really hard to make it right. Before signing anything with him, he spent hours with my family and I to hear what we wanted and provided honest consultation. - They weren't the cheapest bid I received, but they did it at a great price at top quality. Additionally, Dan has a good eye for design and can offer up some suggestions on classic looks/trends with things like tile, colors, patterns and cabinetry. His team even went above and beyond to clean up our messy backyard for us which we couldn't get to cleaning because of a family member's injury. These guys are genuinely good guys, and we are completely satisfied and utterly thrilled with Dan's work. I'd recommend him to friends, family, in laws, even my boss. Our future house projects will definitely be with DMB Builders.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
