What Our Clients Say...

I can vouch for Grantham Builders’ professionalism and reliability. Erik Grantham is knowledgeable, patient, and a man of his word. As a woman with no construction experience, I had many questions! Erik Grantham and his team always took the time to explain and help me understand what was going on — and how to accomplish my renovation goals in an affordable, timely, and sound construction manner.  – Vicki
Grantham Builders added a garage and bonus room to our home. Erik was professional and easy to work with. He listened to what we wanted and made it happen! He kept us posted on progress and any delays. The workers who came to our house were phenomenal as well. We love our new space and highly recommend Grantham Builders!  – Nikki
