Thermo-Tech Support When You Need It

With Thermo-Tech Premium Windows and Doors, you're always working with a knowledgeable team that's ready to answer your questions. Call us. E-mail us. Drop us a line. We're here to help with selection recommendations, questions, installation instructions and trouble-shooting. We loaded this section of the website with videos, brochures and other support materials for easy click-to reference.

We highly recommend that homeowners arrange for professional installation to make sure that your window or door investment fits and functions the way you imagined. Your dealer should be able to recommend installers in your area.

Of course, even the most experienced contractors can't always know what's behind every replacement project. Talk to the professionals at Thermo-Tech when you run into those unexpected situations or odd measurements. You'll get all the support you need, from start to finish.
