What Homeowners Say
“We completed our ADU project in Costa Mesa and it was a great experience overall. Ron handled the project from planning, design and permits throughout the construction. Huge benefit to work directly with the owner and not a project manager or salesman. Two weeks after completion the unit has been rented.”
Leo N. — Costa Mesa
“Just finished a garage conversion in Lake Forest and could not be happier working with Ron, who handled everything from start to finish. Accuracy in each detail! Looking forward to more work with him and his team soon.”
Larissa K. — Lake Forest
“Ron and his team updated our kitchen — painting cabinets, tiled backsplash and new countertops — painted the entire house, replaced several windows and retiled our bathrooms. The quality of work was outstanding, and the price was excellent. Communication was seamless.”
