Weather Stripping & Seals in Los Altos: Stop Drafts and Save on Energy Bills
2026-06-26 7 min read
Most people don't think about their garage door until something goes wrong. But here's what we see in Los Altos every week: homeowners lose hundreds of dollars in heating and cooling costs because their garage door's weather stripping has failed. A damaged bottom seal or worn threshold lets cold air pour in during winter and hot air leak out in summer. The good news is this is one of the easiest, most affordable fixes we offer.
Why Weather Stripping Matters More Than You Think
Your garage is attached to your home. That means it's not separate from your climate control system. When weather stripping fails, you're heating or cooling the entire neighborhood.
Most Los Altos homes experience temperature swings, especially in the hills where it gets colder at night. A worn bottom seal can create a draft wide enough to notice when you walk past the garage entry door. Over time, your HVAC system works overtime to compensate.
We've installed thousands of weather seals in the Bay Area. The cost of replacement is usually between $150 and $400 depending on door size and seal type. Compare that to the $50 to $100 extra per month some homeowners waste in energy costs, and the math is clear.
Signs Your Garage Door Needs New Weather Stripping
Look for these red flags. If you see daylight under your garage door when it's closed, that's your bottom seal wearing out. Feel for a draft near the threshold or around the sides of the door. After heavy rain, check for water pooling inside near the door frame. Visible cracks, brittleness, or gaps in the rubber also mean replacement time.
The bottom seal takes the most abuse because it makes contact with the ground every single time your door opens or closes. We typically recommend replacement every 3 to 5 years depending on use and weather exposure.

Types of Weather Seals and What Works Best
Not all seals are the same. The bottom seal is the most critical component. It's a rubber or silicone strip that sits in a track and compresses against the ground. When it wears, gaps form.
Side seals and top seals matter too. They prevent drafts from entering around the door edges. Many homeowners don't realize these are separate from the bottom seal and may need individual replacement.
We typically recommend durable silicone or EPDM rubber seals over cheaper vinyl. They last longer and handle temperature swings better. Cost difference is usually $20 to $50 extra per seal, but you get 2 to 3 more years of service.

Installation and Cost Reality
Here's where we're transparent. Some companies will quote you $600 or more for weather stripping replacement. That's overpriced. At Garage Door Company Los Altos, we charge based on actual labor and materials, not inflated margins.
A standard bottom seal replacement takes about 30 minutes. Side seal replacement adds another 20 to 30 minutes. Most homes need all three addressed at once for best results.
We offer same-day estimates. Call us and we'll tell you exactly what you need and what it costs before we do any work. No surprises. No upsells on things you don't actually need.
Seasonal changes in Los Altos make this especially relevant. Winter dampness can accelerate seal failure. If you're in the hills or near the peninsula, temperature swings are even more extreme.
When to Replace vs. Repair
Sometimes seals can be repositioned or cleaned instead of replaced. We inspect first and recommend only what's necessary. If the rubber is still flexible and the track is clean, adjustment might buy you another season. But once cracks appear or the material hardens, replacement is the only real fix.

Frequently Asked Questions
How long do garage door weather seals last? Bottom seals typically last 3 to 5 years depending on climate and how often you open and close the door. Side seals often last longer since they experience less friction. Regular inspection helps catch wear before it becomes a major energy drain.
Can I replace weather stripping myself? Bottom seal replacement is manageable for handy homeowners, but it requires removing the seal track and ensuring proper alignment. Side seals are trickier. Most people get better results hiring a professional. The labor cost is modest compared to fixing an improperly installed seal.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber strip that compresses against the ground. The threshold is the aluminum track that holds it. Both can wear out. We often replace the seal while the track remains intact, saving you money.
Will new weather stripping help in rainy weather? Absolutely. A functioning bottom seal prevents water from pooling inside your garage during rain. Check our post about how rainy season affects your garage door for more seasonal insights.
How much will I save on energy costs? Most Los Altos homeowners report $40 to $100 monthly savings after seal replacement, depending on climate control usage. Your HVAC system runs less because conditioned air isn't escaping through gaps.
