Here's what most homeowners don't realize about weather stripping and seals: they're not just about comfort. In Banning's brutal summer heat, a failing bottom seal or worn threshold can drive your cooling costs up 15 to 20 percent. I've been servicing garage doors across the Inland Empire for 15 years, and I see the same pattern every June. Someone calls because their garage has become an oven, their energy bill is shocking, and they finally notice daylight creeping under the door.
The good news is that weather stripping and seals are one of the easiest, most cost-effective fixes you can make right now.
Our climate is brutal on rubber and foam. The desert sun, temperature swings from 105 degrees down to 50 at night, and the occasional dust storm all take a toll. Most weather stripping lasts 3 to 5 years before it hardens, cracks, and stops sealing properly.
When the bottom seal degrades, you lose the thermal barrier that keeps conditioned air inside. That draft you feel under the door? That's your AC unit working overtime. And in winter, when Banning dips into the 40s, that same gap lets warm air escape.
I've also noticed that many homeowners confuse the threshold (the piece at the base) with the weather stripping itself. They're separate components that work together. The threshold is the structural part; the weather stripping is the seal. Both matter.
A worn seal doesn't just affect temperature. It invites dust, insects, and moisture into your garage. If you have a finished garage, a workshop, or you park a car there, that draft is letting contaminants in directly.
I recently worked on a home near Redlands where the owner had ignored a failing bottom seal for two years. Dust had accumulated on everything. The garage had become a thermal liability. The cost to replace the stripping and threshold was under $300, but the energy waste had already cost them hundreds in excess cooling.
When you neglect seals, you're also putting stress on your garage door opener and springs. Your door works harder in extreme temperatures, and that accelerates wear on other components.

Look for these signs:
Visible cracks or gaps in the rubber or foam around the door frame. Daylight visible under or around the edges when the door is closed. Dust accumulation inside the garage, especially along the floor near the door. Higher energy bills without explanation, particularly in summer or winter. Drafts you can feel near the door or threshold.
If you notice any of these, don't wait. The longer you delay, the more you're paying in wasted energy. A same-day estimate costs nothing, and most repairs take under an hour.
Not all weather stripping is created equal. In Banning, you need seals rated for extreme temperature swings and UV exposure. Cheap foam tends to compress and fail faster. Quality rubber or EPDM seals hold up much better.
The threshold also matters. A worn or cracked threshold won't support the seal properly, and you'll have a gap no matter how good the stripping is. Sometimes replacing both together is the smartest move.
Our team at Garage Door Banning stocks materials built for this climate. We can schedule a free quote and walk you through your options. We'll show you the cost difference between a basic seal and a durable one rated for Banning's heat, and you'll make an informed choice.
Installation is straightforward, but it needs to be done right. The seal must sit flush against the door frame with no gaps. If it's compressed unevenly, you'll have a draft. The threshold must be level and secure.
After installation, minimal maintenance is required. A quick visual check once a year keeps things on track. Clean the seal occasionally to remove dust and debris. That's it.
Weather stripping and seals aren't glamorous, but they're essential. In Banning's climate, they're one of the highest-ROI repairs you can make. A $200 to $400 investment pays for itself in energy savings within a season or two.
Don't let another summer spike your cooling bill. Call us at 951-535-4379 or get a same-day estimate online. We'll inspect your door, identify the problem, and give you a clear cost estimate with no pressure.

How long do weather stripping seals last? Most weather stripping lasts 3 to 5 years in Banning's desert climate. UV exposure, heat cycling, and dust accelerate degradation. Annual inspection helps you catch wear early before energy loss becomes significant.
Can I replace weather stripping myself? You can, but it's fiddly work. Improper installation leaves gaps that defeat the purpose. A professional ensures the seal sits flush and is compressed evenly, guaranteeing the draft stops completely.
What's the difference between a threshold and weather stripping? The threshold is the rigid structural piece at the door's base. Weather stripping is the rubber or foam seal attached to the frame. Both work together. A damaged threshold can't support the seal, so both may need replacement.
How much does a weather stripping repair cost in Banning? Most jobs range from $200 to $500, depending on whether you need just the stripping or a new threshold too. We offer free estimates so you know the exact cost before we start.
Will new seals really lower my energy bills? Yes. A failing seal can increase cooling costs 15 to 20 percent in summer. In Banning's heat, that adds up fast. Most customers see noticeable savings within the first month.
