Step 2: Tape a plastic sheet on the interior of the cut out that prevents debris from going inside the house and makes clean up easier.

Step 3: Now, start drilling through the complete wall in a way such that the holes over the exterior wall will help you cut the wall from the outside. Step 4: Also, you can tape the perimeter of the required opening from the outside. By taping off the desired area, it will ensure that the cut does not extend and further reduce the crumbling of the edges. Step 5: In order to cut through the stucco, you can make use of a putty knife. To smooth the edges (of the cut), either a putty knife or a key-hole saw is preferred. Step 6: After getting a clean hole in the wall, place the pet door into that hole from the inside. Use a pencil to mark the tunnel’s portion that you need to chop off. Now, make use of tin snips or jigsaw with the appropriate blade to trim the tunnel. Step 7: Another step is to fasten the exterior part of the pet door.

  • In case the outside ground is comparatively lower than the inside flooring, you can use a platform which makes it easy and safe for your dog to go through.
Stucco walls are generally less than 8” in thickness, so the tunnels don’t need to be as long as those for brick or concrete walls. Also, Stucco walls are typically found in climates that are more moderate (think central California), so the energy efficiency isn’t as necessary. A few good doors for walls like this would be the Ideal Ruff Weather or the Endura Flap (in the single flap version). A cat door for interior walls might follow a similar installation process, but always read the manufacturer’s installation instructions!

Cost of Installing A Dog Door In A Wall

Installation of a dog door in a wall comes up with some challenges especially if you don’t have an idea what to do. Since it’s a labor-intensive task (cutting a hole through the wall) which requires construction know-how, we recommend you to hire a professional pet door installer in your area to install the dog door for you. Also, the presence of electrical wires and pipes in the wall makes it more crucial to hire some professional help. Installing a door through a wall can be less expensive if you are doing it yourself, but if you are not very handy the time and effort you put in maybe worth more than the ‘$200-$300’ you would pay to have a pro tackle the job for you (not to mention the cost of any repairs if something wasn’t done correctly the first time). The overall cost may vary depending upon the tools that are needed and the type of wall wherein you want to install your dog door. Moreover, it also depends upon what the contractor finds when they make a test hole. If there are studs, electrical fittings, or plumbing, then they might likely have to make some changes if you still want to put the dog door there. This may include reframing or rerouting electrical wiring and piping which will further add to the cost of installation in time and parts.

Have these 5 significant points in mind before you start installing the pet doors yourself -

1) Ask yourself how handy you actually are? If you have any doubts, hire out!

2) Knowing where the wires/studs resides in the wall? This is crucial as cutting through electrical, pipes, or load bearing studs can cause serious injuries to you and damage to your home. You can use a stud finder tool to help with this process.

3) Will your pet door fit between the studs? Some doors have wider rough openings than others and depending on how your home is framed and where you are putting the door you may not have enough space.  And the last thing you want to do is find out after making a hole in your wall.

4) How high off the ground should you install your pet door? In general you only want your pets to have to step over about 3” – 5” and will want to make sure the top of the flap is mounted at least 1” above the tallest part of your dogs back. The installation instructions for your pet door should have recommended template placement tips for you.

5) Read through the included installation instructions (and watch online videos) beforehand This is very helpful and even if you aren’t installing it yourself.  You and your contractor can go through it together and that way you make sure they are also installing it correctly.
