Very happy with the investment.Posted on Google Curt WastradowskiTrustindex verifies that the original source of the review is Google. No hassle install. Miss Marple loves the door.Posted on Google Faith NouriTrustindex verifies that the original source of the review is Google. We love our pet door. I have 3 cats and they all use the door. My male cat likes to go in and out 20 times a day and he gets to do that. When I installed the door, I was concerned whether my cats will use it. I used the installer advise to use their clip until they get used to it. Once my male cat started using it, the other two females began using the door. It is a good door and no issues. Thank you.Posted on Google Walt DulaTrustindex verifies that the original source of the review is Google. Hi Jeff, thanks for reaching out and checking up on the status of our doggy door. Both pups have been using it constantly with no problems. They figured it out on the 2nd day and haven't missed a beat. We are definitely happy with our Valley Pet Door.Posted on Google Jonathan SturmTrustindex verifies that the original source of the review is Google. So pleased with our purchase and the whole experience. Found the product I liked but struggled to find someone to work with until I found Valley Pet Door. They were quick to come out and measure, order and coordinate installation. Really seamless and we could not be happier with the product. It is far and away better than the typical insert for sliding doors. It's solid, air tight and our large dogs no longer have to duck to get in and out. It looks amazing and gives us our full door width back. Definitely recommend!Posted on Google Tori CTrustindex verifies that the original source of the review is Google.

Although it took our stubborn dog some time to learn, since then the freedom of the dog door itself has been awesome! Lucy now goes in and out as she pleases. The owner Jeff is amazing!

I am so pleased with this Pet Door; do not hesitate, you will not be disappointed! Jeff who sold me the door, is honest and trustworthy. The kind of salesperson that is rare to find. The installers were efficient, courteous and clean. The door is beautiful and far superior to the old pet door I was using.

The result is fantastic and even better than I imagined.Posted on Google James SwartzTrustindex verifies that the original source of the review is Google. Super happy with our new pet door.

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.
