"Gary and his crew did a excellent job replacing 5 windows.. I had a few other companies give me quotes and Gary's was the best by far. His crew replaced the windows with speed and cleaned and removed all the debris within a few hours. So far the windows meet all my expectations and really make a difference in the comfort of the rooms ."

"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!!"

"Had a problem with a pet tearing my screens. Jay gave me his expert opinion and recommended a pet proof screen. He installed that in the back and a regular screen for my front door. They both look great. So far so good with the pet screen! ?"

"I waited a while because they are backed up due to Covid but they were definitely worth the wait. They were precise, quick and extremely detailed. They put two windows in for me (where windows didn't exist before) and covered up a window. They insulated and everything. No painting but that was cool. I was very impressed. Definitely would recommend them and hire them again...and again....and again"

Windows questions, answered by experts

Yes, every window needs a lintel. The lintel is necessary for redistributing the load above the window to the walls around the window. Windows aren’t meant to support a load, so lintels are an important part of a window installation. If you go to replace your windows and discover there are no lintels, you may need a window company or structural engineer to install lintels for your new windows.

Whether you need a permit to install a bay window depends on the project's scope. Replacing an existing bay window typically does not require a permit. However, if you are adding a new bay window, requirements can vary. Adding a new bay window to the front of your house usually requires a building permit, while adding one to the side or back of your house often does not. It's always best to check with your local municipality to confirm the specific requirements in your area. Additionally, if you live in a historic district, you should consult your neighborhood association to ensure your project complies with their construction guidelines. If you're unsure about the process, a professional can provide guidance.

The best time to remove and restore old windows is during temperate weather. Late spring and the early onset of winter are ideal seasons. While summer has its challenges (e.g., bugs, heat, and dust), it’s also a good time to do restoration work. The worst time to restore old windows is during the winter, especially if it is particularly cold and snowy.

Yes, most manufacturers offer warranties for materials and performance. Confirm terms before purchasing.

Awning windows can have screens, but it depends on your manufacturer. If your awning window does have a screen, it will be on the interior side so it doesn’t get in the way when you crank the window open. Having the screen on the inner part of the window also makes it easier to clean from inside your home.
