I wanted to take a moment and share my experience with Jeff at Valley Pet Door. Seldom do I write a review, but I figure Jeff has been so exceptional in all ways possible I needed to give him a nod. His attention to follow up was great. The pet door his company installed has proven to be worth every penny I spent. My lab loves it and so do my daughter’s and son’s dog’s totaling 5. The door has been proven to be exceptional and my lab and all her guest love it. Jeff is worth call. Mario Garcia2025-04-26Trustindex verifies that the original source of the review is Google. When we were looking for a door for a pet door for our home, we initially bought one of those partition doors. We didn't like it. The price for a door from here is significantly higher but it's worth every penny. Our dogs are so happy now that they can go in and out of the house as they please. If you're on the fence on buying one of these doors, just buy it. You won't regret it. Kym Wilkerson2025-04-22Trustindex verifies that the original source of the review is Google. Truly a life saver!

Found Valley Pet Doors during the Home and Garden show in the AV. An appointment was set up quickly to come measure. While the door was to take 4-6 weeks to get manufactured, it took less than 4 weeks. It was shipped to National Glass in Valencia, who promptly contacted me to have the new pet door installed. From the very beginning, Valley Pet Door was very informative and keep me up to date on the progress. National Glass did an awesome job with the installation. I am very happy that I now have full access to my sliding glass door.

Our doors come in a variety of sizes and opening options. Whether you have a German Shepherd, a Terrier, or any size dog in between, our doors have a build that can work for them.
Do you have a feline friend? Cats can use our doors as well. In fact, our small flaps are light enough to open easily and are more flexible and safer than the rigid cat flaps on the market.
Glass doors and windows are actually made from any one of a number of kinds of glass. Each one of these will need a different procedure to cut into or replace.
Attempting to cut a hole in tempered or dual pane glass will shatter it. Other kinds of glass will crack badly, creating an unsightly and potentially dangerous hazard.
New advancements in technology have made pet doors significantly more energy efficient.
Our pet door insert utilizes the finest glass and vinyl materials available to ensure an energy efficient solution for you and your beloved pet. The insert will allow your patio door to slide, function, and lock as originally designed.
