Jason is very knowledgeable and caring. Would highly recommend. Final product looks clean and we are happy. Far superior to any insert you would get.

Jason was really great to work with! I had a pretty custom need which he was able to accommodate. The entire process was smooth and straightforward, and we now have an awesome dog door in our existing sliding glass. It is absolutely perfect. Secure, wind and weatherproof, looks great, and all of our dogs love it!

Jason did a very good job and even came back to deal with a touch-up issue. I recommend him highly.

Through the Glass was fantastic! The scheduling process was easy. They made two visits to my house. The first was the measure. The second was to install. It took no time at all and saves me time every single day. They were super friendly and professional. And, to top it off, the size of the dog door is perfect and the quality is the best I’ve seen. Thanks to Through the Glass, I did not need to create a hole in the house. I am not sure who is happier, my dogs or me?

Did a great job with the dog door! The dogs love their new freedom. Very professional, reliable and great work!

Very professional install. Well worth the money. Jason was very knowledgeable and nice. The door is way more energy efficient than the old panel insert. Looks gorgeous.

Jason and his crew are wonderful to work with. Fantastic energy savings with high quality materials and workmanship! Well worth the investment, and professional service. Highly recommended!
