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!

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?

Jason was response and attentive from start to finish! He replied within 24 hours of my initial inquiry and scheduled an appointment within a week. I had several questions and it's clear he really knows his craft. The door was received within three weeks of our meeting. The day of the installation couldn't have taken more than an hour and it looked beautiful. The only issue we had was the lock on the door cover breaking within a week of installing it. Apparently this is quite rare and Jason immediately said he'd replace it. Overall I found Jason to be compentent, professional, and trustworthy; all qualities that are becoming harder and harder to find.

Jason was always prompt and explained the process of replacing the glass in our large sliding glass door. The door is western-facing, and we were concerned about the high winds up on the ridge where we are. The door seals tightly and hasn't needed the cover to keep the wind out. We highly recommend this dog door and Through the Glass Dog Door.

Jason with Through the Glass Dog Doors did an outstanding job for us. He was always prompt, polite, courteous and cleaned up after himself. Because our slider door was either not installed properly by the installers years ago or possibly the door along with the house settled/shifted it was not your typical job but with Jason’s experience and know how he was able to dismantle as well as install the new door without too much trouble. The door is beautiful and our pooch loves being able to come and go on her own. We would confidently recommend Jason with Through the Glass Dog Doors for your doggie door needs!

I had a considerable experience with Jason at Through the Glass Dog Doors! He was in constant communication with me through out the process. When he came to my home, he was kind, and considerate of his surroundings. When he was finished with the doggy door he cleaned up and disposed plus extra. Then took his time with me to ask and answer any thoughts or concerns to insure a flawless outcome! The door looks great, seals out all wind, and more importantly my two puppers love it as well! I would highly recommend Jason and Through the Glass Dog Doors!

Amazing door, absolutely no draft when standing right next to it. Keeps the weather out and the heat in. And its amazing beginning able to have the whole sliding glass door back.

Wonderful experience. Very happy with my doggy door that is in glass. It’s double flapped and I don’t feel wind blow through like one I put in in NY. The owner was responsive and dependable. A great experience and worth the money.

Ashley Mcclure

Very professional, quick, honest and helpful. Jason was great to work with and had our new door installed right in the window he quoted. No more drafts coming in the house, dog adjusted quickly to the new door and we are very happy with the product and service.

Conor Linehan

Great job by Jason on our Through the glass dog door. We previously had the standard panel dog door which was terribly energy inefficient and our kitchen was freezing on these cold wintery days. Though it was a tad expensive it’s been totally worth it. I highly recommend Jason and Through the Glass Dog Doors. Exceptional quality and highly professional !! We love our new dog door.!
