My new roof, gutter helmet and downspouts are installed and I must say Trim A Seal did a first class job. Britt, Holland, Doug and Darrell were all very professional and the clean up was amazing. I didn't know men could clean up as well as women!! It was a totally good experience!

We are thrilled & more than satisfied with how our garage floor turned out. Pat was our salesman and presented the product and installation process professionally and without pressure.

Mike was our salesman and he was great to work with , no hard sell , no bad mouthing his competitors, unlike the other company that came out. The installers were extremely friendly , explained everything they were doing and cleaned up after they were done. Highly recommend.
We love our Sunsetter awning! From the time we met with the friendly and helpful salesperson from Trim-A-Seal to the efficient and talented installation crew everyone was courteous and professional. We face west with the sun reflecting off the lake so an awning was a must. We are very happy with our choice of product as well as Trim-A-Seal.
