What Are The Benefits Of An In Glass Pet Door?
There are so many benefits to installing a pet door that you and your companion will enjoy including:
- Convenience: You will no longer have to adjust your schedule to let your pet outside. No more rushing home from work, getting up in the middle of the night or waking up early to take them outside.
- Comfort: When you are gone, your pets have to wait until you return to use the restroom. This can cause your pets a lot of discomfort. Allowing them to go outside when they need to go can offer pets a more comfortable life.
- Fewer Accidents: Giving your pet access to the outdoors can reduce the number of accidents around the home. Instead of having to wait until you let them out, they can go when they need. A pet door is especially great for puppies and senior dogs who do not have good control of their bladders.
- Healthier Lifestyle: Giving your pet the freedom to go outside and play can help them lead a healthier lifestyle with more exercise and activity.
- Happier Pets: Happy pets are well-behaved pets. Most pets act out because of boredom or stress. Giving them the ability to go outside when they want can reduce behavioral problems.

I’ve had my “through the glass door” doggie door for just over a year now. Jason did an excellent job when he installed it last November. I couldn’t be happier with it over the last year. It’s well worth the money because of the convenience, quality and aesthetics. I am so glad that I didn’t buy one of those dog door inserts for my sliding glass patio door. My puppy easily adapted to using it, and so have my kid’s dog’s that come to visit. I love the fact that I can close it at night or at other times.The double insulated flaps really work well in keeping the cold air out even when it’s windy and they’re easy to clean. II wouldn’t think twice about getting a “Through the glass dog door”. You won’t be disappointed, it’s worth the investment!

Amazing. I am so thankful for the wonderful work that was done. My dog thanks you too.

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.

Jason is amazing and provided impeccable service . Door is high quality and looks very nice . Highly recommend.

Jason was timely, professional, and did an excellent job replacing our sliding glass doors and installing a dog door for our pup. Strongly recommend TGDD to anyone looking for similar work.

I am so happy with my dog door. It looks great - our sliding glass door is a focal point in our main living area so we didn't want just an insert. This looks really nice! We've had compliments on it even. And working with Jason was great. He was quick and explained everything to us. I would highly recommend them!

Through the Glass Dog Doors did an amazing job on the installation on the installation of our new dog door and I would highly recommend them. We were using an insert that went between the sliding glass door and the wall and the difference is amazing. The new door does not blow open in the wind, we are saving a ton on heating and cooling since the door can stay closed and sealed now, and it is great being able to open the sliding glass door all the way.

Jason went above and beyond helping me get my second dog door installed in my new kitchen door- Beautiful job and the dogs and I are so happy w the results!! Only way to make us all happy was "through the glass" !!!

Jason was extremely responsive to our inquiry, and delivered the final product not only on time, but it exceeded our expectations. High recommend Jason and his team for your reimagined dog door!

Through the Glass responded quickly when I reached out looking for an in-door dog door. The service was prompt and efficient. My new door looks amazing and the dogs are happy with it. I appreciate the safety of being able to lock the sliding door and the dog door. Would definitely do use them again if I ever need another one.

Quick and easy installation and has made a huge difference in convenience for us and our 3 dogs. Highly recommend!

We love our new dog door. Installation went well and efficiently. It’s everything we expected.

Jason was so professional and quick to respond! The quality of his work is fantastic and he explained the whole process why there has to be a new door made as opposed to simply cutting the old door. He uses both energy efficient glass and an energy efficient dog door! It is one of the nicest looking dog doors we have ever had. We absolutely recommend his quick and kind service to others!
Great service , On install day the door was on in one hour.Came out better than I had imagined.I would definitely recommend them. I was going to install one myself but man am I glad I called these guys zero stress.
There was no good place in our house to put a dog door until we found Through The Glass Dog Doors. We've had our door for about two years and it has paid for itself many times over now that we don't have to board our dog somewhere else every day we go to work.

Our dog LOVES his new dog door. Through the Dog Door was prompt with estimate and install. Very professional with whole process. Highly recommend!

The dog door in our sliding glass door has been a game changer for our pups! These guys were quick, professional, and recommended some extras without doing a hard upsell. Turnaround time was quicker than expected, and the door works great! I definitely recommend their product and service!

I was very impressed with the process of getting our custom sliding door made. They friendly guys from Through the Glass took just a few minutes to measure the sliding door and returned in 3 weeks with the new door which was installed in less than half an hour. They also fixed the lock on our door which had been broken for years and carried the old piece of glass down to my storage room for me. We are very happy with the door itself, as are our four pets! Our big dog had it mastered almost immediately and our little dog took some coaxing but soon figured it out. Our cats appeared to not understand it for a while and then one day they just started using it. Typical cats. Now we can seal up the old hole in the wall dog door and keep our sliding door closed and the pets can still come and go. And without one of those inserts that make the opening awkwardly skinny for people when it is open... The glass sliding door behaves as it always has, but now the pets can go through it. It's the perfect solution!

We looked and thought about getting a dog door installed in our sliding door for a couple of years. I had several estimates done. Through the Glass Doors was professional and above all else the most knowledgeable. I had the most comfort with the answers to my questions. The install was fast and proficient. We love it and our two fur kids love it!!

Really happy with our new doggy door, and the dogs are too! Excellent customer service and very professional and Covid-safe installation. Our glass arrived 2 weeks earlier than originally quoted and Jason was a breeze to work with! Definitely recommend Through the Glass Dog Doors if you are looking for a high quality and space saving option for your pups.

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.

Great communication, service and product! Our dog learned how to use the door quickly. He loves being able to go in and out when he wants. We love that he doesn’t scratch our door anymore when he needs out. Would highly recommend this company if you are in the market for a wonderful dog door!

Thank you Jason!!!! We love our door!! Jason was so nice and professional he went above and beyond.

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.

Installers were very professional and on time. Quality of door was great and works well.

Very pleased with my dog door! It has good insulation and very pleasing to the eye!

What an amazing job Jason did! The glass is perfect as is the dog door. My dogs have been using it since we put it on and 0 issues with install or design.

Best investment for our family. She was using the door after 2 days and the quality is better than the door qe started with!

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 really great. He came out to my home promptly, took the measurements, and once the door/glass came in, he installed it super quickly. The door looks great and I get so many compliments! The dog loves it too.

Fantastic! Timely response. Excellent product. I highly recommend Through The Glass!

Awesome experience. It took a couple weeks to get the glass in but absolutely worth the wait and the $. The dog door itself is high quality and I don’t feel the drafts like I did with a single flap door. The dogs and humans are very happy.

We highly recommend Jason and Through the Glass Dog Doors. Jason offered superior customer service throughout the process. He was informative, prompt, and communicated well from start to finish. We are impressed with the quality of the product and the install. Thanks, Jason!

Fast and easy.. the door works great for our boy. These guys knocked it out of the park

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!
