Weatherseals That Keep Minnesota Winters Out (and Critters, Too)

What to Replace

Bottom seal

Match your retainer type—T-style, P-bulb, or beaded. Don't force the wrong profile.

Perimeter vinyl

Low-temp flexible seals that won't crack at -20°F like cheap rubber does.

Top seal

If you see light at the header, replace the top seal to prevent heat loss and moisture entry.

Special Minnesota Considerations

Pitted slab? Use dual-durometer bottom seals to bridge gaps and prevent water infiltration that leads to ice damage.

Real ROI

• Warmer garage (important for attached garages)
• Fewer freeze risks above the garage
• Less salt dust in living spaces
• Keep mice and insects out year-round

Quality weatherstripping pays for itself in the first winter through reduced heating costs and prevented water damage.
