I am absolutely thrilled with my garage floor! They did a fantastic job. It's so beautiful it looks good enough to be another room addition. I highly recommend Trim-a-Seal

I had to wait a long time for my awning to arrive, but it was worth the wait. Tim's crew was here early and on time. Got the job done, cleaned up and left me with instructions and a new awning. Hope to enjoy it for many years

I want to say thank you to the trim a seal team especially to Mr. Weiss and the the install team led by Holland. They made a difficult situation turn out absolutely beautiful. Mr. Weiss is a man of his word. We will be using trim a seal in the future fir some concrete work and garage floor work. I highly recommend this company and I will always recommend them to friends and family.

Outstanding experience from start to finish. Office staff kept us informed of the expected service date. We had an awning installed on our lake home. Installers came on time and they were very friendly and professional. Installed unit and did a wonderful job of matching to our siding. Thoroughly explained operation before they left. Great product and service. Highly recommend this company.
