How To Go About Wall-Installed Dog Doors

Many homeowners realize the importance of dog doors, which are structures that are typically made from aluminum frames. Most dog doors come with one or two flaps to give extra protection against rough weather conditions. If you live in a cold region, then a double-flap dog door is a must. The extra flap will keep the cold air outside, keeping you warm and cozy inside the house.

If your dog has a bad habit of interrupting you from your daily activities just to get you to open the door, then a dog door is in order. By installing one into an exterior door or wall, you can save precious time while leaving your dog free to roam at will.

Just make sure that you get a dog door that conveniently matches the size of your dog.Otherwise, you’ll be facing the original problem that was bugging you before.

Having a dog door in the house gives your pets an excellent way to exercise and explore without getting in your way. In other words, it’s a good way to save time and give your pets the independence they crave. If you’re planning to install a dog door in a wall in your house, make sure that you do it right so that you can maximize its benefits.

Installing the Dog Door

Installing a dog door in the wall is not as complicated as it seems. You don’t need any technical background to get this job done. In fact, you can probably do it in just one afternoon if you have all the right tools. Here’s a guide on how to install a dog door in a wall.

Things You Will Need

  • Tape measure
  • Pencil
  • Straightedge
  • Torpedo level
  • Carpenter’s square
  • Drill
  • 1/2-inch drill bit
  • Saber saw
  • Two-by-fours
  • 2 1/2-inch screws
  • Silicone caulk
  • C-clamps
  • 1/8-inch drill bit
  • 1 1/2-inch screws
  • Waterproof glue


Step 1

The first step in installing a dog door is always locating the best place for it. There are two main considerations when deciding on a location. First, you need to make sure that the wall allows your dog to access both sides freely.

Make sure there’s no object blocking either side. Second, you have to make sure that there’s nothing above the dog door that can impede the flap movements. Once you find the perfect place that meets both requirements, you’re ready to start.

Step 2

Now, you need a tape measure and a pencil to mark the place where you will install the dog door. Measure three inches from the bottom plate of the wall in which you wish to install the dog door.

Step 3

Once you have the initial markings, it’s time to complete the dimensions by making horizontal marks. You can use a straightedge and a torpedo level for this. If you do the markings right, you’ll end up with a rectangular illustration that reflects the dimensions of the dog door.

You can use a carpenter’s square to even out the edges. If you don’t know the exact dimensions you need, just consult the instruction manual that came with the dog door you purchased.

Step 4

Drill a half-inch hole in all four corners of the rectangle, then use a saber saw to cut along the outline. Make sure to do the interior side first and cover the outside.

When you’re done with the interior, drill four more holes through the outer wall to delineate the corners. Make sure to use the holes as a reference when drawing a rectangle and cutting it out from the other side.

Step 5

Once you have a hole in the wall, you can proceed to create a frame that will block up the gap between the wall coverings. Afterward, measure the distance between studs, then produce two lengths of two-by-fours, which you can subsequently screw into the studs using 2 ½-inch screws. Check if the faces are flush with the top and bottom edges of the hole. If they are, cut two more two-by-fours to fill the rest of the gap.

Step 6

Cut the dog door frame in half, then spread silicone caulk in the flanges of each side. After this, fit both frames on either side of the wall. You’ll know if you’re doing this right if the two halves are overlapping midway through the opening.

Step 7

Using C-clamps, join the two halves of the dog door together to hold the flanges tightly against the wall. Afterward, drill two 1/8- inch pilot holes on both sides of the frame, then drive a 1 ½-inch screw into each one to secure the dog door in place. Remove the clamps once you’re done.

Step 8

Your dog door should come with nonslip PVC strips that you can glue to the bottom and sides of the dog door. Your task is almost done; all that’s left for you to do is waterproof the door by caulking the edges of the frame on both sides of the wall.

Don’t postpone installing a dog door, especially when you see a great need to do so. With these easy-to-follow steps, you can surely accomplish this task with no trouble.
