Tips for How to Cover Up an Old Dog Door

  1. Remove the existing dog door completely before attempting to cover it up and ensure all of its parts are gone. This is important to prevent your pet from getting stuck or hurt in the opening and to avoid any potential safety hazards.
  2. Check the area where the old dog door was located for any sharp edges or splinters that may have been left behind. Before applying any type of covering, these should be sanded down with medium-grit sandpaper.
  3. Clean the area thoroughly to ensure there is no dirt or debris that could cause problems when applying the cover. This can be done with a vacuum, broom, dustpan, or damp cloth.
  4. Measure the area carefully and cut out a piece of plywood that is slightly larger than the opening to ensure proper coverage. Mark off where any nails or screws will need to be placed to secure the wood.Cut Out a Piece of Plywood
  5. Secure the plywood against the wall with nails or screws in the appropriate positions. Ensure that the covering fits properly and is flush with the wall’s surface.
  6. Apply weather-resistant caulk or putty around any gaps that may be present between the plywood and the wall to ensure a tight seal against moisture or insects.
  7. Cover the plywood with a coat of paint or varnish to make it look more aesthetically pleasing and protect the wood from weathering. Follow up with a second coat for added protection.
  8. If desired, hang artwork or other decorations over the covered dog door to add visual interest and conceal it from view.

These steps will help ensure a safe and successful cover-up of an old dog door. With the right supplies and a bit of time, it’s easy to ensure that your pet can no longer access this hazardous opening.

How Should You Go About Insulating the New Dog Door to Prevent Drafts From Coming Through It?

  • Measure the size of your old dog door, including the frame and insulation strip surrounding it. You will need to cut new insulation slightly larger than the old one to ensure a good fit when installing it.
  • Purchase a rigid foam board designed for insulating dog doors from your local home improvement store. This foam insulation is often sold in 4’x8’ sheets and can be cut to the exact dimensions of your old dog door.
  • Cut the insulation board to fit around the frame and seal any gaps with an adhesive caulk or foam sealant. Be sure to use a product that is designed for outdoor use to provide the best insulation.
  • Install a weather stripping seal around the frame of your dog door, paying special attention to any gaps that may exist between the foam board and frame. This will help keep drafts from coming through your new insulated dog door.
  • Finally, paint or stain the frame and insulation board to give your new dog door an attractive finish. This will help make the new installation look more like a part of your home’s original design.

How Should You Go About Maintaining and Cleaning Your New Dog Door Once It is Installed? 

  • Make sure that your new dog door is properly installed and secured in place before you begin to clean or maintain it.
  • Use a damp cloth or sponge to regularly wipe down the frame and pet flap of your new dog door to remove dust and debris. Be careful not to use any harsh chemicals or abrasives that could damage the surface.
  • Check the screws, hinges, and other fasteners of your new dog door every few months to ensure they are tight and secure. Tighten them if necessary.
  • To prevent insects from entering through your new dog door, wipe down its frame and pet flap with an insect repellent.
  • If your new dog door is made of wood, treat it with a wood sealant or similar product to help protect it against rot and other damage caused by the elements.
  • For more serious maintenance needs, consult the manufacturer’s instructions or contact a professional if necessary.

By taking these steps regularly, you can ensure that your new dog door is in good condition and will last many years.

How Often Should You Check Your New Dog Door to Make Sure It is Working Properly?

It is best to inspect the door and surrounding area for damage or other signs of wear. Check that all screws, bolts, and latches are secure and in place. Make sure that no debris is blocking the flap and that it opens correctly.

If you find any signs of damage or malfunctioning, replace the dog door immediately to prevent further damage or harm. For more tips on maintaining your new dog door and keeping it working properly, consult your manufacturer’s instructions or contact a professional installer for advice. With regular maintenance and inspections, your dog door should be able to provide safe and reliable access for years to come.
