Michael Duffy is the owner and creator of MDC Construction Services, a residential remodeling company serving homeowners throughout South Orange County. With more than 30 years of experience in whole-home remodeling, he’s built a reputation for craftsmanship, thoughtful planning, and lasting relationships with the homeowners he serves.
Michael started out on the East Coast, restoring 18th-century homes — work that gave him a lasting appreciation for preservation, detail, and the character that makes a home worth keeping. He brings that same sensibility to every project today, offering homeowners practical recommendations, creative solutions, and confidence throughout the remodeling process.
MDC Construction Services specializes in residential remodeling, home preservation, historic home renovation, and aging-in-place remodeling. Michael and his team focus on helping homeowners turn their current home into a comfortable, accessible, and luxurious “forever home” — one that fits their evolving lifestyle without losing what they already love about the space.
Proactive communication, careful planning, and attention to detail define how MDC works. Michael knows that letting a construction crew into your home takes trust, and he’s built the company around making that partnership feel steady and reassuring from start to finish.
Through MDC Construction Services, Michael brings craftsmanship and lasting value to homes across South Orange County — and to the Aliso Viejo business community.
