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.
Just finished our exterior project. New siding, windows, gutters, soffit, and front door. it's literally like having a brand new house! We love the finished product and love the professionalism from everyone involved. You've gained lifelong customers
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.
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.
We give Adam and Richard a A+, great job enjoyed them being here on time ,friendly , explied well, couldn't ask for more!
We struggled to find a gutter guard capable to protect our new home surrounded by trees. Gutter Helmet is the CLEAR right choice. Trim A Seal handled the installation professionally and on time. We got what we were promised!!
Our Installers, Holland and Darrell, both did an exceptional job of installing our new awning. They explained the operation of the unit thoroughly. Top notch team!
I had maintenance done on my gutters and I was pleased with the work. Would use this company again.
This morning trimASeal came out to start on my siding, met with Adam and Richard, we did the walk around, Adam explained everything so I understood it, and he is very easy to talk with and very knowledgeable, will post after the job is done to.

Bruce was very personable and professional. He educated me on the product options, enhancements and construction quality of Trim-A-Seal door products. Bruce will insure you get quality and satisfaction with exactly what you want to purchase. Thanks, I will return when it's time to get my windows.
They took care of some unexpected problems for my grandfather and did what they could to make things work. Adam and Richard did a wonderful job.
