Sealing Gaps Between Siding and Foundation With Sheet Metal
One of the most effective barriers against mouse infiltration is custom-bent galvanized sheet metal, which you’ll find superior to softer materials that rodents can easily chew through.
This approach gives you complete control over sealing large gaps between your siding and foundation, eliminating potential entry points that mice commonly exploit.
Install the sheet metal during dry weather to guarantee proper caulking adhesion. Focus particularly on corners, where siding installations often leave vulnerable areas unsealed.
The galvanized material’s durability makes it an ideal barrier that resists rodent damage while providing long-lasting protection.
After installation, conduct regular inspections to maintain the sheet metal’s integrity. Check for any loosening or damage that could compromise your foundation sealing efforts and allow future mouse access.
Protecting Utility Entry Points and Meter Boxes
While your foundation and siding provide the primary barrier against mice, utility entry points and meter boxes create some of the most vulnerable access routes into your home.
Meter boxes often contain baseball-sized holes for power cables that become major entry points if you don’t seal them properly. You’ll find similar vulnerabilities around pipes and electrical lines where they enter your house.
Regular inspections are essential to spot gaps or damage that compromise your defenses. When you discover openings, use stainless steel mesh or custom-bent sheet metal to seal these areas effectively.
These materials provide long-lasting protection that prevents rodent access. Don’t overlook these important spots – mice can easily navigate through utility entry points, making proper sealing vital for maintaining a mouse-proof environment.
Weatherproofing Garage and Basement Access Areas
Your garage and basement access areas represent critical vulnerability points that mice exploit to enter your home.
You’ll need to focus on sealing garage doors properly and securing all basement entry points to create effective barriers.
These spaces often connect directly to your home’s interior, making them high-priority areas for thorough weatherproofing efforts.
