In our years serving Redwood City, we've seen this problem again and again: homeowners lose hundreds of dollars heating or cooling their homes because worn weather stripping and seals let air escape around the garage door. The good news? Replacing these components costs far less than you'd expect, and the payback happens within months through lower energy bills.
Your garage door isn't just an entry point for your car. It's one of the largest moving parts of your home's thermal envelope. A single worn bottom seal or damaged threshold allows conditioned air to leak into unconditioned space, forcing your HVAC system to work overtime.
Most homeowners don't realize how much they're spending. A gap of just one quarter-inch around your garage door can cost $15 to $30 per month in wasted heating or cooling energy, depending on local temperatures and how often the door opens and closes. Over a year, that adds up fast.
The Bay Area's mild winters mean some Redwood City residents procrastinate on this repair. But spring and fall temperature swings, plus moisture from coastal fog, make weather stripping maintenance just as critical here as anywhere else.
Look for these red flags:
Visible cracks or gaps. Run your hand along the bottom seal and sides. If you feel drafts or see daylight, replacement is overdue.
Rubber that's hard or crumbly. Quality weather stripping stays flexible. When it hardens, it no longer seals properly.
Water pooling inside the garage after rain. A failed bottom seal lets water infiltrate during storms, leading to rust, mold, and structural damage.
Increased utility bills with no explanation. If your heating or cooling costs spike, a draft around the garage door is often the culprit.
The threshold, which runs horizontally at the bottom of the door opening, deteriorates fastest because it bears weight and exposure every time the door cycles. Most thresholds last 5 to 8 years before needing replacement.

Let's talk cost versus benefit. A full weather stripping and seal replacement typically runs between $150 and $400, depending on your door size and whether the threshold needs replacement too. Check our garage door pricing guide for a detailed cost breakdown.
That investment pays for itself in 4 to 8 months of energy savings. After that, every dollar saved is profit. Over the 5 to 8 years before the next replacement, you're looking at $1,000 to $2,400 in cumulative savings. That's the kind of ROI most home improvements can't match.
Beyond energy, proper seals protect what's inside your garage. Tools, holiday decorations, and vehicles stay safer from moisture and pests when the door seals tightly. If you've already invested in weatherproofing your garage door for Bay Area seasons, fresh seals are the logical next step.
Some homeowners attempt this repair themselves. Removing old adhesive, measuring correctly, and aligning new seals requires patience and precision. If the bottom seal sits even slightly off-center, it won't seal properly.
Professional installation ensures the job is done right the first time. Garage Door Redwood City technicians bring proper tools, quality materials, and experience hanging thousands of seals across the Bay Area. We also inspect the door frame and hinges while we're there, catching small problems before they become expensive repairs.

Sometimes weather stripping alone isn't enough. If the threshold itself is cracked, bent, or rotted, replacing just the rubber seal won't stop drafts or water infiltration.
A full threshold replacement runs $200 to $350 and takes about an hour. It's a worthwhile investment if the threshold shows structural damage. Ignoring this leaves your garage vulnerable to flooding and pest entry.
Don't confuse a threshold with a weatherseal. The threshold is the metal or composite frame piece. Weather stripping is the rubber gasket that seals the gap. Both work together. Both wear out. Both need attention.

How long do garage door weather strips last? Most rubber weather stripping lasts 5 to 8 years before hardening or cracking. Exposure to California sun, coastal salt air, and temperature swings accelerates wear. Annual inspection helps catch deterioration early and prevents costly secondary damage.
Can I replace weather stripping myself without removing the door? Yes, most side and top seals can be replaced without removing the door. However, the bottom seal often requires careful alignment and adhesive application. Professional installation guarantees a tight, lasting seal and saves frustration.
What's the difference between a bottom seal and a threshold? The threshold is the structural frame piece at the base of the opening. The bottom seal is the rubber gasket attached to the door itself. Both seal the gap. Both wear out independently and may need separate replacement.
How much money can I save by replacing worn weather stripping? Energy savings typically range from $15 to $30 per month, totaling $180 to $360 annually. Over a 6-year lifespan, that's $1,080 to $2,160 in recovered utility costs. Actual savings depend on your climate, energy rates, and how often you open the door.
Is weather stripping replacement covered by warranty? Most seals and thresholds come with 2 to 5 year warranties against manufacturing defects. Labor warranties vary by company. Ask about coverage when you request your estimate.
