Replacing Garage Door Seals to Keep Pests Out Prudential Pest Solutions


Mice are persistent pests that can squeeze through the tiniest of cracks and crevices, making their way into garages, homes, and other buildings. Sealing the gaps and cracks around your garage door is an essential step in keeping these and other pests out of your home. Here we’ll discuss how to keep these unwelcome guests out by sealing your garage door effectively.

How to Seal Garage Door Gaps Mice

The best way to seal your garage door against mice is to use a weatherproof caulk that can be applied to the edges of the door. Start by inspecting the entire door frame, looking for any gaps or holes that a mouse could squeeze through. If you find any, use a utility knife to cut away any old or damaged weather stripping or caulk, then apply a new bead of caulk along the door frame. Make sure to get into the nooks and crannies, as a mouse can squeeze through incredibly small gaps.

Once you’ve sealed the door frame, you can seal the door itself. If your garage door is made of wood, use a paintable silicone caulk to fill in any gaps that you can see. If your door is metal, you may be able to use a metal weatherproof sealant to fill any gaps. Make sure to use a sealant that is appropriate for the type of door you have so that it will form a strong seal.

The Pros of Sealing Garage Door Gaps Against Mice

Sealing your garage door gaps against mice is a great way to keep them out of your home. It’s also relatively inexpensive and can be done in a few hours. Additionally, sealing your garage door will also help keep out rain, wind, and other elements that can damage your home over time.

The Cons of Sealing Garage Door Gaps Against Mice

The biggest con of sealing your garage door is that it may not be effective if the mice already have access to your home or garage. You may need to take additional steps, such as using traps or poison, in order to completely get rid of a mouse infestation. Additionally, if not done correctly, the sealant may not form a strong enough bond and the mice may still be able to get in.


Sealing the gaps around your garage door is an effective way to keep mice out of your home. It’s relatively inexpensive and easy to do, and the seals will help keep out the wind and rain as well. However, if you already have an infestation, additional steps may be necessary to get rid of the mice. Be sure to consult with a professional before attempting any pest control measures.
