Thermo-Seal was scheduled to side our house when in one of the many storms this spring, our roof got damaged. We hired Thermo-Seal to do both jobs and could not be more pleased. The crew was efficient and neat on both jobs. The general manager Bob was on site to answer any questions or concerns that we had. They also took care of all of the paperwork for our insurance company for the roof and that was a blessing. We would highly recommend Thermo-Seal to anyone who needs work done. The owner Aaron is very proud of his company and it shows in the work that the company does and the pride that his workers take. Love them!!!!!!

What a GREAT are beautiful and the workers did an absolute perfect job...clean, neat, and finished off beautifully. They even touched up with my paint and seemed to enjoy going the extra mile to please...Aaron is a great guy who loves what he does and is proud of the company and his family of workers. I would recommend Thermo-Seal Windows and Siding to anyone who wants quality work at great prices.

I bought a condo last year that had severely damaged 35 year old windows. You could barely see out of them and they wouldn't budge. I called several companies, and Aaron was the first to take the time to explain clearly and professionally how the process would work, and he gave a very fair price. He came and measured the windows, ordered them, and his guys came to install. They were extremely professional. There was a problem with the construction of the window, there was no frame installed! So they quickly ran and grabbed the supplies, installed the frame, sheet rocked, and installed the window in the same day. They turned a possibly stressful situation into a very pleasant experience, again for a very reasonable price. I have been recommending them to everyone. Still after 10 months, the windows look and function great. I have to bring them back to change my slider, what a difference the new windows make. Definitely give them a call.

Aaron and Bob provided a wonderful team of 4 men to replace plywood and siding using Hardie cement boards on my home. Project completed in 7 days, looks fabulous and neighbors are telling me how good it looks and the great professional job that they did. I am very pleased and happy to never have to worry about peeling paint again!

— Joanne H.

I recently worked with Aaron and Bob and their outstanding crew to have replacement windows installed; and while we ran into an unforeseen water issue, Bob went above and beyond to replace a previously and poorly installed flat roof and gutter system for me - quickly. I don't usually go out of my way to give a 'rave review' about window and roofing contractors, but these guys are worthy. They're respectful of your home, neat, clean and very efficient! I plan on having them back in the near future when I'm ready to do new siding. HIGHLY RECOMMENDED.

Just got all new windows, casement, double hung, and even a big 4 panel bow for my front window. Dealt with Aaron, Bob and crew. They were courteous, professional, and really fast! House feels warmer already and windows look beautiful inside and out! Thanks guys!! Would definitely recommend!

Thermo-Seal just completed a project for me. Competitive - Competent (very) - Courteous (very). Work exceeded expectations. Highly recommended. Ask for Aaron to handle all your needs.

Aaron and Thermo-seal are the best! Always available, always on time, great prices, outstanding follow up and stand by their product. Even my general contractor couldn’t believe the high quality at their price! Now he uses Thermo-Seal, too!

— Lori D.

Very satisfied with my Thermo-Seal windows. Did the whole house last year. My heating usage was decreased and I love the windows. So easy to clean. Aaron is wonderful and I get fast responses to my issues. Very happy I went with Thermo-Seal.

— Cathy M.

Aaron and his team were amazing, from start to finish! They worked with us every step of the way and Aaron was always just a call or text away to answer any questions we had. The windows are perfect and we love them. We highly recommend working with Aaron and his team. They are professional, courteous and their work is top notch!
