Our Story

Daniel McMahon’s passion for building started at a young age when he, as a young boy visiting family in New Jersey, drew up plans for a family room addition and redwood deck for his aunt’s house. Throughout high school he would spend summers working with his wood-shop teacher repairing the docks at the Richmond Yacht club. Throughout all of these experiences Daniel never lost his passion for hands on building which prompted him, as an adult, to found McMahon Construction Services.

From home repairs and remodels to commercial property a professional approach to constructing quality projects which meet budget and schedule goals is of top priority.
