We are very happy with our new windows. We immediately noticed the house was warmer and less draughty and of course they look much cleaner and the new window trim looks nice and modern. I also want to take this opportunity to commend the 3 guys that were here to do the install. They were all professional, courteous, and very efficient and let us know how the job was progressing at every step.

Windows were beyond expectations we are extremely happy with the quality and finish.

We love that you build your product locally and that you back it with exceptional service, and accordingly, we will absolutely recommend Thermoproof to anyone asking about windows.

If I require further window services I will use Thermoproof. I am a happy customer and appreciate excellent service.

We are SO happy with our new windows!!! The process to order was super fast and the production time was only a couple weeks. The installers were the icing on the cake. Absolutely the most considerate trades people we've dealt with to-date.

Thermoproof windows in Duncan BC have good quality windows, better than all the other brands readily available in my area (South Vancouver Island). I did my research and concluded after much comparison of price, warranty, and overall product, I made the decision to go with Thermoproof. Made in Cowichan valley.
