In our years serving San Jacinto, we've seen this problem again and again: homeowners lose hundreds of dollars in heating and cooling costs because their garage door's weather stripping has dried out, cracked, or peeled away. The good news is simple. Replacing worn weather stripping and seals is affordable, fast, and one of the smartest energy investments you can make.
San Jacinto sits in Riverside County where summer temperatures regularly hit 100°F or higher. That relentless desert heat ages rubber and foam seals faster than anywhere else in Southern California. UV rays break down the material. Thermal expansion and contraction cause seals to shrink and separate from the frame. Within 5 to 7 years, even quality weather stripping loses its grip.
When the seal fails, warm air escapes in winter and hot air leaks in during summer. Your HVAC system works twice as hard to maintain temperature, and your energy bill climbs. Many homeowners don't realize their garage door is the culprit until they compare utility costs year to year.
Weather stripping refers to the rubber, vinyl, or foam material that runs around the perimeter of your garage door. The bottom seal, also called a threshold seal, sits along the base of the door and takes the most punishment. It compresses when the door closes, creating a tight barrier against outdoor air, dust, and pests.
Side seals run vertically on both sides. Top seals seal the gap where the door meets the header. All three work together to eliminate draft and maintain your garage's climate. When any one fails, the entire system loses efficiency.
Over time, seals harden, crack, or simply fall out of their tracks. You might notice light showing under the door, cold air rushing in, or insects finding their way inside.
Look for these red flags around your garage door. Visible cracks or gaps in the rubber mean air is escaping. If you feel a draft near the bottom seal on a windy day, replacement is overdue. Peeling or missing sections of foam indicate the adhesive has failed. Light visible under the closed door signals the seal no longer compresses properly.
You might also notice your garage feels noticeably warmer or cooler than adjacent rooms, or your energy bill has spiked without explanation. These are all signs your bottom seal and side seals need attention. Addressing this during a routine garage door maintenance visit prevents bigger problems down the road.

Pricing depends on which seals need replacement and the size of your door. A bottom seal typically costs between $150 and $300 installed. Full perimeter sealing, including all three sides and the threshold, usually runs $400 to $600. These are honest numbers based on real material and labor, not inflated estimates.
The return on investment is quick. Homeowners report 10 to 15 percent reductions in monthly energy costs after sealing air leaks. In San Jacinto's climate, that easily adds up to $50 to $100 per month during peak heating and cooling seasons.

Delaying this repair costs you more in wasted energy than the repair itself. Unlike some garage door work, weather stripping replacement is straightforward and affordable.
You can buy weather stripping kits online, but professional installation ensures proper fit and longevity. Our technicians measure your door frame precisely, select the right material for San Jacinto's climate, and install seals so they compress evenly when the door closes. Poor installation leaves gaps or causes the door to bind.
We also inspect your door hardware and springs while we're here. If something else needs attention, you'll know upfront before costs spiral. That's the honest approach we take with every job.
Worn seals don't just waste energy. They allow dust and moisture into your garage, which can corrode springs, rust hinges, and damage your garage door opener. Moisture is especially harmful in areas with temperature swings. Keeping seals intact protects your entire door assembly.
Regular seasonal maintenance catches seal wear early. Spring and fall inspections catch cracks before summer heat or winter cold makes them worse.

How long do weather seals last? Quality weather stripping typically lasts 5 to 7 years in San Jacinto's climate. UV exposure and extreme heat age seals faster than in cooler regions. Annual inspections help catch deterioration early.
Can I replace weather stripping myself? It's possible, but professional installation ensures proper compression and fit. Poor DIY installation leaves gaps and may cause the door to bind or not close fully. Our technicians complete the job correctly the first time.
What's the difference between a bottom seal and side seals? The bottom seal sits under the door and bears weight when it closes. Side seals run along the sides and top. Both matter, but the bottom seal typically wears out first and needs more frequent replacement.
Will new weather stripping reduce my energy bill? Yes. Homeowners typically see 10 to 15 percent reductions in heating and cooling costs after sealing air leaks around their garage door. Savings are larger in homes where the garage is insulated or attached to living spaces.
How much does weather stripping replacement cost? A bottom seal runs $150 to $300. Full perimeter sealing with all three sides typically costs $400 to $600. Call 951-724-4202 for an estimate based on your specific door and situation.
