The Pet Door Guys: Pet Door In the Glass

The best way to install a pet door through your existing sliding glass door frame is by replacing the glass with a Pet Door Guys unit! The new glass will have a pet door installed at the bottom, and you’ll be able to use your sliding glass door like normal. A glass professional will be needed to come measure your current glass and later swap it out for the new glass that has the pet door. The pet door that is used is the energy efficient Endura Flap, which is an insulating, flexible flap perfect for extreme weather. The flap system is extremely durable and carries a 15 year warranty.

How to Order

  1. First, check that one of the installation options is suitable for you. They are:
    • 2 Panel Slider: Installation in either side of the inside track panel. When using the center-post side, it's important to ensure that the screen will not interfere with the action of the pet door flap.
    • 3 Panel Slider: Installation may be in either side of inside track slider or jamb side of 3rd panel. The same concern applies to the screen as above.
    • 4 Panel Slider: Installation may be on either side of either inside track panel
  2. Review How to Measure Your Pet to choose the appropriate size opening for your pet. The unit will have a minimum 3 3/4" step-over height in addition to your existing frame, so be sure to take that into account!
  3. Engage a local glass shop willing to do the measuring and installation. The glass shop installer disassembles your sliding glass door (a very easy job), takes width, height and thickness measurements then re-installs your glass slider. He completes his portion of the Order Form.
  4. Read our Detailed Information Page to get more specific information about how this works. Be sure to share this information with the local glass shop. If the installer has questions have them contact us directly and we can answer any specific questions they may have.
  5. Purchase the product. Your total for merchandise, shipping and any sales tax will be shown. Charges from your local glass shop are not included, so you would pay your installer separately.
  6. Once we receive your order, we'll send you an email with a form that asks for the measurements of your glass.
  7. We then arrange with the factory to custom-build a new piece of glass with the pet door in the lower corner that you specify. We have that unit shipped to your glass shop.

At your convenience the glass shop installer returns to your home, uninstalls your glass panel and replaces it with the new panel containing the pet door.

You are responsible for payment to the glass shop for the measurement and install. We will charge you only for the pet door. In our experience, the cost for these two service calls will likely be between $120 and $200 but you may want to establish this cost in advance.

More Important Info

  • Click here for more information about LoE glass.
  • The vinyl framing is available in white or beige and that's what you're choosing in the drop down product select. The pet door framing comes only in white.
  • Because this is a custom order all sales are final.
  • Glass that is 34" x 76" or smaller is considered "standard" size.
  • Glass that is larger than 34" x 76" is considered "oversize".
  • You can get an approximation of your actual glass size right now by measuring the "daylight" dimension (just what you can see) and adding 3/4" in both dimensions. This is NOT accurate enough to order the product.
  • Allow about 3-4 weeks plus transit time for delivery.

  • Fantastic review by Betty

    5 5 Fantastic

    Love this! We took a gamble living in Canada and had it shipped to a U.S. Address and picked it up. Our glass installer measured for the order and installed it today. We love it! So glad to get the full width of the door back. The panel was good but this is amazing. When we saw it we weren't sure it would work. It comes not as just a pice of glass but a glass in a frame that fits into your door frame. Very minimal reduction in view. Genius really. Thank you!!!

    5 5 An awesome pet door

    This is the most awesome pet door we have ever come across. Upon stumbling onto Pet Door Guys, I was wondering how a pet door would fit into my sliding glass door. I was also concerned with my dogs breaking it. But I must say when it arrived and was installed, It was quite impressive. The dog door is fantastic for my two medium size dogs. We opted for the large door because of friends dogs that we watch that are quite large. Now I see that I made the best choice. Our dogs go in and out without having to stop and arch their body to get through. This is the best purchase made for our home and the dogs just love it. Highly recommended.

  • good product review by Yuma AZ. retiree
    How do you rate this product?
    5 5 good product

    The door has been a relief to us. Our dog is a hunter/pointer of anything that moves. She sits inside looking for lizards and birds in "her backyard". It was a constant motion letting in or out all day long. In the Yuma heat the out part is very short.
    I think you could sell a bunch of these doors if you would find a local dealer that would advertise in the paper. The glass man never heard of this product. When I did call some glass companies before I found your internet service they had not a clue of what I was wanting.
    The flapping of the door when the dog goes thru it is like a loud door knocker. Very loud at noise in the dead of night...

    5 5 In Glass Door

    Brought a new home in May. the dilemma what to do with fido.
    options patio door insert, didn't seal well and made it difficult to get to the patio, other option was to cut a hole in the house or put dog doors in 2 doors. found Pet DOORS in a search and thought it was a good option. Best buy i have made in a while. works great and looks wonderful.

    5 5 Excellent product!

    Wish I had know about this product when we first moved to Colorado! I spent lots of money, which was wasted in the end on the doors you put inside the sliding glass door. They never fit right and you could never really seal it up.

    I wound up cutting a hole in the house and putting one of those in. That worked great.

    When we moved into our new home I could not put one in. Once again I tried the type you fit into the door. Once again could not get to fit and could not seal.

    Did a search and found pet door guys. Excellent product! We erred on the side of caution and got one bigger then we needed and the step over for our dogs is a bit too high. We had to do this because there is no returns on their products.

    When it is all said and done we love the product.

  • "In The Glass" review by SG in Virginia

    5 5 "In The Glass"

    I absolutely love this dog door in the glass. Now my patio door opens, shuts, and locks normally again. All my friends are very impressed when they see it. We tried the panel insert first, but our patio door is fairly small (3 foot wide slider), so the panel didn't leave much of an opening for us. So we really needed the "in the glass" feature. Fit and finish on the "in the glass" door (and the panel door too) are flawless. We have owned several pet doors over the years and these are definitely top of the line pet doors. Definitely worth the price, especially when the winter wind howls, the magnetic edge really holds it closed. Our previous pet doors did not stay closed when the wind blew.

    We purchased our door a couple of months ago and we love it. It is so much better than the panel door we had before. My husband installed it himself and it fit perfectly. The dogs like it too.

    And my door is working well. My English Springer Spaniel uses it appropraitely! One day, we were playing Tennis in the house! Right in the middle of the game. He picked up the ball, went outside,went Pee, then came back in to continue the ball game! Yeah!!

    I have since let the Pet Nanny go! And, only worry about some of the surprises! One of my cat's uses the door! They both catch Gecko's and Lizards as gift's. Life is good over here in Spring TX!

    Thanks again!

  • The Perfect Solution review by Prano

    5 5 The Perfect Solution

    We have used panels in the past and have never been happy with how they kept the elements out. The "In the Glass" door solved several problems for us.
    Our door opens immediately to steps, there is no landing at the same height as the flooring. Our last pet doors had such a high rise that we needed to have a deck built over our steps to allow our dog to easily go in and out. The low rise on your door and the height of your door opening works perfectly with our step up.
    Our pup needed to adjust to the strength of the magnetic seal, but now she flies in and out of the door easily.
    Best of all is that we can open our door completely. We had trouble moving our recycling bins when we used a panels.

    My spoiled puppy knows how to go in and out the door...for treat's. He still wants me to open the door for him for potty time! Once I had my budget for the door, everything went smoothly with ordering and delivering. Thanks Pet Door!!

  • Looks great review by Chris

    5 5 Looks great

    I wish it also had RFID like the Cat Mate doors we used to have, as we just had a neighbor cat try to get in just before this review. Other than that, it is wonderful. Looks very nice. We were faced with having the cats go through 2 doors, into and out of the garage, to the front yard, when then want to get to the back yard. I know my cats and they wouldn't put up with that. They would just paw their muddy paws on the sliding glass door until I let them in.
    I was not clear what we'd have to go through to get this done. You get a professional glass person to come measure your glass and get specs. You send in this info. The product is made in Lynwood, WA and I was able to pick it up to avoid shipping. You bring back the professional and they install. You get the glass and it is inserted into your existing sliding glass door frame.

    5 5 Great product and service during product research, purchase, and installation.

    I purchased one of your "In The Glass" pet doors last spring. I was a little leery about this type of door "keeping the weather" out in our cold winters. We get lots of snow and wind during the winter. The door and flaps worked great for our 2 dogs, a German Shepherd and Dalmatian. My wife has complained for years about the draft from our previous sliding glass door panels. But the "in The Glass" door worked great. I would not hesitate recommend these doors for anyone considering this option. They have been very sturdy with virtually no wear. Both of our dogs tend to "bolt" through the door. The door appears very durable. I would purchase one to put in any sliding glass door.

    Great product and service during product research, purchase, and installation.
