About Cornerstone Builders

Cornerstone Builders works with homeowners planning meaningful renovations and custom spaces where process matters as much as the final finish. We guide design, budgeting, selections, scheduling, and construction with one clear line of communication.

Company story

Built on steady local reputation

Cornerstone Builders was founded to serve homeowners making major decisions about the homes they plan to stay in. Mark and Amy's kind of project is exactly the kind the company was built for: substantial, personal, and too important to hand to a disorganized team.

Over the years the firm developed a structured design-build process for kitchens, baths, additions, outdoor living spaces, and custom homes. That process creates clarity early, when the budget, selections, and timeline are still flexible enough to shape well.

Clients stay with Cornerstone because the team communicates clearly, manages trade partners carefully, and protects the experience as much as the finished craftsmanship. In custom work, trust is earned long before the trim goes on.
