I am completely satisfied with Trim-A-Seal installers. They did a great job installing my SunSetter motorized awning. They explained and showed me how it worked and answered all of my questions. I definitely would recommend them.

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. Tom and Jerome were our installation team and were professional, conscientious, thorough and were very hard working. Based on our experience we would not hesitate to recommend Trim-A-Seal.

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.

Shelley Black

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.
