On the linked episode of This Old House, starting at 16:00, they install an extra large PlexiDor Wall Series door for the homeowner’s Newfoundland. They go above and beyond, replacing the exterior siding around the door for a classic look that blends right in to the adjacent house door.
The PlexiDor dog doors and cat door are available for door or wall installation. The door kit makes it easy to install the pet door through a standard house door. A somewhat handy person can do this themselves and it doesn’t take long.
The house door isn’t always the best place for the pet door – sometimes a wall fits better. The PlexiDor wall kits can be installed in cement, stud, brick or block walls up to 12 inches thick. The kits come with an aluminum tunnel to connect the interior and exterior frame.
Installing through a wall can be trickier than installing through a door – it is more difficult to make a hole in the wall than through a door. (An important tip is cutting from the outside – keep the mess outside the house!) You also need to check if it’s a load-bearing wall or not.
This video shows how to install a PlexiDor through a door and through different forms of walls. It begins with installing through a door. Wall installations start around 9 minutes in and will go through the installation process through different wall materials.
When installing a pet door, it’s usually easiest to put it through a door. However, the PlexiDor cat doors and dog doors can be installed in all sorts of walls, and the PlexiDor wall unit gives a professional grade wall installation.
The wall units can be installed into stud, brick, block, or cement walls up to 12 inches thick. Each wall unit includes a sloped aluminum tunnel that connects the interior and exterior frame. The tunnel will not rust, and it is easy to clean.
If your wall is thinner than 12 inches, just trim the tunnel pieces down with included jigsaw blade or tin snips.
The PlexiDor wall units come in the same sizes and specifications as the door units: Small, Medium, Large, and Extra Large. Colors available are silver, white, or bronze.
Tools needed for installation are: jigsaw, drill, and screwdriver. (Jigsaw blade is included with the unit.)
If you need a pet door, the PlexiDor is sturdy, secure, energy efficient, and comes with a five year warranty. Here are answers to some frequently asked questions.
Where can I install a PlexiDor?
The PlexiDor can be installed through a door, a wall, or even through glass. The part you see next to the doggie on the picture goes on the inside of the house.
The PlexiDor units for door installation fits a standard US house door of 1.75″ and the frame covers the cut-out edges of the house door.
The units for wall installation come with an aluminum wall tunnel that is adjustable from 4″ to 12″ On the image to the right, the door is seen from the outside of the house. The aluminum tunnel is angled to drain water and snow to the outside.
When it comes to installations in glass, every size door from the small one to the extra large and the electronic PlexiDor can be mounted in a sliding glass door, french style door, or window. To read more about this and to see installation photos, please follow this link.
What kinds of pets can use a PlexiDor?
The PlexiDor comes in several sizes to accommodate everything from cats to dogs weighing up to 200 lbs. The doors on the larger models swing so easily that smaller pets can use a bigger door.
The door looks so small. Will my dog really go through there?
If you have the right size according to the PlexiDor SizeChart, the answer is generally “Yes.” The door isn’t meant to be mounted flush with the floor; the pets lift their legs and walk/run over a threshold. The reason for this is that you want the opening to be as small as possible while still being big enough for your pet.
Looking at the chart above, the extra large PlexiDor, for example, should be mounted 12″-14″ up from the floor, unless a dog needs it to be lower.
Is it hard to teach a pet to use the door?
Pets generally catch on to the idea quickly. Prop the panels open and tempt your cat or dog with a treat. Once they go through with the panels open, try the same thing with panels closed. Many pets who won’t use other pet doors still like the PlexiDor because they can see the other side through the panel.
What warranties do you have?
The PlexiDor comes with an unconditional 90 day money back guarantee. Shipping charges are non refundable, but the factory will refund the purchase price in full.
The PlexiDor also comes with a 5 year warranty. Any defective part will be repaired or replaced, including standard shipping charges, for five years from the purchase date. Labor is not covered.
This warranty covers residential use. Commercial kennels should use the BiteGuard line of pet doors.
Do you have a door that will let my dog out but keep the cats inside?
We can’t guarantee that. The PlexiDor Electronic opens only for pets with a key, but cats are quick and can follow the dog outside.
How does the PlexiDor Electronic work?
It’s like a miniature garage door for pets. The pets allowed to use the door get collar keys with RFID. The keys are waterproof, shock proof, and do not require batteries.
When the key comes close to the door, the panel slides up. You can program how long the door will stay open, and since there are thousands of RFID codes you can feel confident the door will only open for your pets, even if other animals in the neighborhood have similar keys.
