Things You'll Need:
- Jigsaw with two blades in case one breaks
- Power drill with 3/8 inch drill bit
- Phillips and slotted screwdriver
- Pencil
- Measuring tape
- Metal file
- Work gloves
- Safety goggles
- Level
- Stud finder
-
Step 1
Locate near-by studs with a stud finder.
-
Step 2
Tape the template of the pet door on your wall and trace the outline of it. Be sure to mark holes where you need to drill. The cut-line should be 1 1/4 inch or more above the dog's shoulders for a single flap wall mount, and 2 inches for a double wall mount.
-
Step 3
Measure the outer-most distance between the walls. The wall must be framed out like an exterior door or window. This will create a box to install your dog door in.
-
Step 4
Locate, cut out, and frame the dog door tunnel (as you would a door or window) that is properly sized for your new dog door. Build the frame in square and level for best results.
-
Step 5
Dry-fit the doggie door to your cut hole.
-
Step 6
Secure pet door in frame using door jam stock or similar material inside and out.
-
Step 7
Screw together the four screws and caulk around the edges to form a nice weather-tight seal. Have your dog do a test run to make sure it can fit through the door comfortably.
