A patio pet door is extremely useful to cat and dog owners because it helps decrease the likelihood of your pets having accidents inside the house. Once the pets are trained to use the pet door, they will be able to get outside themselves. Also, if you have a job that requires you to be out of the house all day, you will feel less guilty about leaving your pets at home all day. With a patio pet door, they can go in and out as they please.

Step 1 – Measurements

Measure your pet's height and width with a tape measure to ensure that you make the patio pet door large enough for your pet to pass through comfortably. As pets vary so much in height and width from breed to breed, there are no set measurements for this project.

Step 2 – Mark the Area

Use masking tape to mark the screen door where the patio pet door will be placed. Using tape is more practical than using a pen, as it is easier to see and remove.

Step 3 – Remove the Screen Door

It is easier to install the patio pet door if the screen door is not attached to the door frame. Therefore, try to carry out this job on a pleasant day with good weather. Remove the door with a screwdriver, and use a utility knife to remove the portion of the screen door inside the taped area.

Step 4 – Construct the Pet Door Frame

Create a wooden frame for the patio pet door so that the inside dimensions match the measurements you made earlier. Construct the frame with four pieces of wood secured together with waterproof wood glue and nails. The glue should be placed along the joints, and two nails should be used to secure each joint.

Step 5 – Construct the Door

Attached the door using a hinge. Secure one-half of the hinge to the side of the wooden frame that will be indoors, and the other half of the hinge to a sheet of plastic that will act as the door for your pet. The plastic should be cut to a snug fit to prevent drafts.

Step 6 – Install the Pet Door

Attach the wooden frame to the hole that you cut into the screen earlier using epoxy, and leave it to dry. Make sure that the flap is positioned so that it is facing inside the house.

Step 7 – Replace the Screen Door

Once the epoxy has dried, you can replace the screen door. Place it back into the door frame, and secure it with a screwdriver.

Step 8 – Optional

If you live in a cold climate, you might want to put another flap on the pet door. The second flap should be situated on the outside of the wooden frame as well to prevent heat escaping and cold air getting in through the patio pet door.
