Step 1: Cut Wooden Plywood to Fit Dog Door
The first step should be to buy plywood and cut it to the size of the interior door. The key is to cover the doggie door if you don’t plan on using it during the winter. Take the necessary measurements of the interior space within the dog door.
Then cut the plywood according to those measurements.
Step 2: Cut Insulation Foam to Fit Dog Door
You should also purchase your choice of insulation foam. You can use the cut plywood as a reference for cutting your insulation foam.
Step 3: Check That It Fits
Taking your cut pieces of plywood and foam, you should check to see if they fit inside of your dog door. Simply place them on the outside of the door to see if they fit within the door. If there are any gaps, then you may want to consider filling those areas with more insulation foam.
Step 4: Install Foam
Once you’re ready to install the foam, you simply need to place the insulated foam inside the dog door. It should be able to rest snugly between the wooden plywood (to be installed next) and the flap or dog door on the other side.
Step 5: Paint Plywood
If you want the wood to better match the door, then you may consider painting it. A painted slab of plywood looks better than an unpainted version.
Step 6: Install Plywood
Once the foam is in the door, you can place the plywood within it the doorframe. It should be pressed tightly to the foam to create a firm seal.
Step 7: Seal the Door
Taking your choice of caulk, you should then seal the edges around the plywood. You may want to perform a few passes in order to create a strong seal.
If you don’t want to permanently close up your dog door, then you may want to use magnetic weatherstripping instead. These are straps that can secure the wooden plywood to the door throughout the winter. It seals the gaps without permanently doing so. During the warmer months, you can simply remove the weatherstripping, then take out the plywood and insulation foam to restore access to your dog.
Step 8: Seal Interior Dog Door
Take some time to pass your hand along the interior of the dog door. If you feel any cool air coming from small gaps, then you may want to seal those areas with caulk.
How Do I Stop Wind From Blowing In My Dog’s Door?
There are a few ways that you can keep the wind from blowing through your dog door. A study by Green Builder Media showed that dog doors can actually increase your heating costs by 6%. To stop that increase, you’ll want to include another flap for your door.
If you only have one door flap, then the cool air will quickly pass through it to access your home. A second flap further insulates the door and makes it harder for air to pass through the door.
Another way to keep the window from blowing through your dog’s door is to replace flimsy flap doors with an industrial plastic curtain material. These are thicker flaps that can still be used by a dog. However, because of their thickness, they keep cool air from easily accessing your home. Installing two of these into your dog door will be an effective way to keep the frozen temperature outside.
Adding a magnet to the bottom of your flap is also an effective method for keeping air from accessing the home. When the flap door closes, the magnet keeps the door snapped tightly to the bottom of the door. This removes gaps that may emerge otherwise.
How Do You Keep A Dog Door From Freezing?
Electronic dog doors may pose a problem with freezing. If the electronics inside of the door freeze, then they may not open. You can find a solution by adding insulation to the door. If the door is installed on a wall, then you can add the insulation on either side of the door. You may also want to add insulation between the door and its frame.
Dog doors that are installed to a door should also have insulation foam added between the door and the frame. This can keep the electronics from freezing.
If you’re unable to add insulation foam, then you can also purchase heat tape. Use this tape to cover the edges of the door and any areas where the bulk of the electronics are kept. Heat tape keeps the area within it insulated.
How Do You Seal A Doggie Door?
Sealing a doggie door can be messy. Follow these steps to make it easier.
Step 1: Choose the Proper Sealant
There are tons of different caulks and sealants for sealing objects. You should choose your caulk based on the kind of finish that you want to have. Do you want the seal to match the color of the door or dog door? Do you want it to be translucent? Answering these questions should help you decide which sealant you need.
Once you’ve chosen your caulk, you’re ready to start preparing your dog door.
Step 2: Apply Masking Tape to the Exterior Dog Door
Using masking tape, you should run the tape along the edges of the dog door. Make sure that you press firmly down on the tape. It needs to follow any dips that the door’s texture provides.
Masking tape is important in helping your sealant keep to the gaps rather than spreading all over the door.
Step 3: Apply Sealant
Once you put your caulk inside of a caulking gun, you can run it along the seams of the dog door. It should be the seams that fit the door to the human door rather than the interior of the dog door.
Step 4: Clean Sealant
You may notice there are a few globs. The masking tape will take care of most of the globs, but you may want to clean up a few other areas. Using a paint stirring stick, you can scrape away or spread the sealant to create a smoother surface.
Step 5: Remove Masking Tape
Before the sealant dries, you’ll want to remove the masking tape. Do so by pulling up on the tape.
Step 6: Wipe Off Excess Sealant
You can choose to clean up the sealant again by carefully wiping it with a cloth or paper towel.
Step 7: Seal the Interior
Following the same steps above, you’ll want to do the same thing for the interior of the dog door. Use tape to keep your sealant controlled. Then apply the sealant, clean it, then remove the tape.
Step 8: Let it Dry
Depending on the sealant that you bought, you may have to wait several hours for it to cure. You may also have to apply another layer. If you do, then simply repeat the steps to create a clean, sealed, dog door.
