Keller and sons recently installed new gutters and reroofed our back roof which had started leaking. I was very impressed throughout the entire process Amanda was very detailed and thorough with the estimate, the installers did great work and left zero mess. Would absolutely use them again and recommend there services to anyone needing gutter, roofing, or siding work done.

The folks at Keller were a pleasure to deal with. Their quote was very close to two others I solicited, but was by far the most complete in explaining what it included. Their work was great. With the new roof and gutters, the house looks like new. For the most part, they were timely and cleaned up well and the people in their office were very responsive to any questions or concerns. Highly recommended.

We rcvd estimates from 3 diff companies & went with George J. Keller as they seem to really know what they were doing & addressed details that other companies overlooked. The workmen were very professional & courteous. They worked quickly & efficiently & did proper clean-up. Communication with company was clear. We are very satisfied with our new roof & are very relieved it's not leaking during rainstorms anymore! Thank you!
