Client Experience
Trusted for Detail-Driven Construction Work
“My original call was for a single door knob installation that others couldn't be bothered with. He later solved a structural design flaw in my 1970s home. The tall buckling living room wall was compromised structurally by roof load. D&D repaired the structural defect without tearing out a single living room wall. He's the contractor I've called back for every project since."
