If you've ever felt cold air seeping under your garage door in winter, or noticed bugs and dust finding their way inside, you already know the problem: worn weather stripping and seals don't work. Replacing them stops drafts, keeps your garage warmer, and saves money on heating and cooling costs year after year.
Our coastal Bay Area climate is tough on garage doors. Salt air, temperature swings between 50 and 80 degrees, and occasional rain all wear down rubber seals faster than you'd expect. Most weather stripping lasts 3 to 5 years before it hardens, cracks, or peels away from the frame. See our guide on garage door openers in redwood city: which type costs less to own?.
A failing bottom seal is the most common culprit. It takes the brunt of every garage door cycle, flexing thousands of times per year. When it deteriorates, you lose the threshold barrier that keeps pests, water, and cold air out. If your door has gotten stuck before, damaged seals often contributed to the problem. We covered this in depth in our guide to garage doors stuck in Redwood City, where seal damage is a frequent root cause.
Here's the honest truth: a new weather stripping and seal job typically costs between $150 and $400, depending on your door size and seal type. That's not expensive. What is expensive is heating a garage that leaks energy every single day. Read about how much do garage door springs cost in redwood city?.
A home with a poorly sealed garage door loses roughly 10 to 15 percent more heating energy in winter months. If your garage is attached to your house (as most are in Redwood City), that cold air creeps into your living spaces. You end up running your furnace harder. Over a year, that adds up to real money. A fresh seal pays for itself in 6 to 12 months through lower utility bills.

Weather stripping comes in three main types. The bottom seal runs across the base of your door and takes the most punishment. The threshold is the metal or rubber strip on the garage floor that the door rests on when closed. Side seals run vertically along both sides of the frame.
All three wear out. When we inspect your door, we check each one. Sometimes the bottom seal alone needs replacing. Other times, side seals have dried out or the threshold is bent. We give you a clear estimate before any work starts. No surprises, no padding the bill with unnecessary repairs.

You can buy weather stripping kits online. They're cheap. But installation matters. If the seal isn't compressed evenly against the frame, it won't seal properly. Gaps remain. The door may not close smoothly. You end up wasting the material and still have a draft.
A professional knows how to remove old adhesive, prep the surface, and install new seals so they sit flush. The job takes about an hour. We use commercial-grade materials rated for California's climate swings. Your door closes tight and stays that way for years.
Watch for these warning signs. Cold air leaking under the door in winter. Daylight visible around the door frame when it's closed. Water pooling inside after rain. Insects or spiders nesting near the garage opening. Any of these means it's time for new seals. Don't wait for spring or next year. The sooner you seal the gap, the sooner you stop losing money.
