About Our Company
At GM Renovation, we bring over 15 years of hands-on experience to projects that add real value to your home. We’re a local, owner-involved general contracting company that’s fully licensed and insured, and we work closely with our clients from planning to final walkthrough. While we specialize in building high-quality home additions that expand living space and integrate seamlessly with the existing home, we focus on strong structure, clean finishes, and a smooth process from start to finish.
Homeowners trust us because we’re reliable, communicate clearly, and stay involved every step of the way. In addition to additions, we also handle attic conversions, basements, kitchens, bathrooms, decks, windows & doors, flooring, and more—bringing craftsmanship and attention to detail to every project.
