Came home to find my new doors installed - they were able to schedule us a couple of days early and put two crews to work, so everything was done, from arrival to clean up and gone, in less than 8 hours. The 3 new doors look great, and more importantly, immediately made the house more comfortable and secure.

Thermal Gard is the best around! The last installation was on S. Baxter. My tenant was amazed at the knowledge and professionalism of the installation crew, I told him they are the best. He agrees!

I cannot say enough good things about Thermal Gard. We recently had two new doors installed and new windows a few years back. The quality is outstanding….our heating/cooling bills have gone down and the house is quieter. The employees are very friendly and professional as well. Thank you for the great product and installation
