Cannot begin to say how amazing this company and the owner, Jason, is. The installation was done with the upmost professionalism and highest quality. The installation process was quick and easy. Highly recommended! Best dog door business in Colorado hands down!

It's been several months now and I wanted to post to say how much we love our pet door. Jason was great to work with and the process was quick and very professionally done. Looking back we wonder how we ever got along without it. And I know our puppy is much happier now. Worth every penny. I highly recommend Through the Glass for anyone looking for a high-quality solution.

We love our new doggie door! Jason was great to work with. We were needing to match tinted glass on our sliding door and had talked to a number of other companies who couldn't do it. Jason came through and the dogs love it. Worth every penny.
Shelley Maher
Jason was very responsive and helpful. He worked with our property manager to complete the work prior to our move in date so we had one less thing to worry about. Work was done timely and as specified.
