What Our Customers Have to Say…
“We are SO happy with our new in-glass dog door! Michael was on-time, quick and helpful during installation. John, the owner, was absolutely fabulous in guiding us down the path and helping us choose the best dog door for our home. Our new dog door feels safe, there is no longer a draft, and is WAY better than our dog door insert. I highly recommend Best In Glass Dog Doors for any of your pet door needs!”
“As a home automation nerd, it was very important to me that my dog door for my new puppy be a smart door with a proximity collar. None of the home improvement stores had doors to suit my needs. I was very lucky to be recommended best-in-glass by an employee at one of the big box stores.
Security was one of my concerns as our backyard faces an open space, so they installed super tough glass both in the door and the dog door–no flaps here.
We ordered some extra supplies from the smart dog door company and they missed them. It was very nice to have John as our liason, who worked with the company directly to assure we had everything we ordered before making our final payment.
I highly recommend best-in-glass for a custom dog door solution. They delivered exactly what we needed.”
“Our door came in much sooner than expected, the installation was quick and looks incredible. And every representative we worked with was excellent!”

“Dog door was installed about a month ago and it’s been amazing! We’ve had some really strong winds in our area lately and it’s held strong. I got pretty lucky on timing because they said it could take 6 weeks due to supply chain issues but got installed 3 weeks from the day it was ordered!”

“Mike is awesome. Both the sales and install process were completed by him. Very efficient, very professional, extremely knowledgeable. He even texted the door lock part that I needed, because we had lost track of the locking mechanism after removing it for the door insert. New dog door looks and works great! You might have to wait a month plus from first visit to install, but that’s pretty typical in today’s world, across industries. Happy with our purchase! Thanks Mike, very much.”
“I was so pleased with the service we got! We had try an insert for our patio door, and when it became a burden we reached out to other places who wanted to do more or charge more and we were not finding what we wanted. John came out and walked us through the product so well and made our decision simple.
The installation was quick and easy, and everyone was so friendly. We have been so pleased with how this has alleviated so many headaches, we wish would have found Best In Glass sooner!!
The quality, cost and company are worth the five stars!”
“These dog doors are much better than anything you’ll find in a big box store! Having the dog door built inside the sliding glass door is a complete game changer.
John came over to our place and helped pick the perfect size door. And Mike did a great job with the installation. Highly recommend!”
