"Peter and his team did a wonderful job of presenting the product, discussing the job, giving a fair price, constant communication, as well as a wonderful install process. We would absolutely recommend this company for vinyl siding replacement and will be calling them for windows in the future."

"I'm so happy with my new windows! My only regret is that I don't have more windows to replace! Aaron and his team were a dream to work with - communicative, friendly, and direct. They worked with me to scope out exactly what I wanted and they were very transparent and fair on price. The installation team was efficient and respectful, making sure everything was done to the utmost standards. My windows look amazing but more importantly they work fantastically! I was shocked at how much quieter and cooler my house was after the new windows were installed, and they are so much easier to keep clean. I will be recommending Thermo-Seal to everyone!!"

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."
