"Our roof and gutters were badly damaged with storms last spring (2024). Our insurance (State Farm) initially denied our claim. Enter Excel and the amazing Amanda and other team members. They went toe to toe with our insurance company for months. Finally, a year later, State Farm relented and approved for us an entire new roof and gutters. Amanda always kept us in the loop, worked closely with our insurance company and made sure we were approved for everything we need. The roof and gutters were done in 1-1/2 days (we have A LOT of roof) and the yard was left immaculate after they left. From our great salesmen at the start, to Amanda in the office, to the crew that finished the work, our experience with Excel was 10 out of 10."

Kevin, homeowner

"Love my new front door! Matt is a great salesman who knows his products front to back. He was super helpful and patient choosing the best design for us. My wife and happy with our choices. Installation was great and painless. Steve cleaned up after his installation and made sure my children stayed clear of the work area. Couldn’t recommend this company anymore."
