After 15 years working on garage doors across Lakewood and Oakland, I can tell you the most overlooked maintenance item isn't the springs or the opener. It's the weather stripping and seals around your door. When these fail, your garage becomes a conduit for outside air, pests, and moisture. Your energy bill climbs. Your HVAC system works harder than it should. The fix is simple, affordable, and worth doing sooner rather than later.
Weather stripping runs along the sides and top of your garage door frame. The bottom seal (also called a threshold seal) sits at the base where the door meets the concrete. Together, they create an airtight barrier that keeps drafts, rain, and unwanted critters out. See our guide on weather stripping & seals in lakewood, ca: why your garage door leaks air.
Most Lakewood homes use rubber or vinyl stripping because it's durable and cost effective. It compresses when the door closes, creating a tight seal. Over time, UV exposure, temperature swings, and normal wear cause the material to harden, crack, or separate from the frame. Once that happens, air leaks through. Water pools. Insects get in.
The good news? Replacing weather stripping is one of the cheapest maintenance jobs you'll do on a garage door. We're talking $150 to $400 depending on door size and seal type. Read about commercial garage doors in lakewood: types, cost & heavy-duty options.
Look for visible cracks, gaps, or areas where the rubber has pulled away from the frame. If you see daylight around the edges when the door is closed, that's a red flag. You might notice a draft when standing near the sides or top of the door, or pest damage along the bottom seal.
When you run your hand along the stripping, it should feel slightly flexible. If it's hard as plastic or crumbles when touched, replacement is overdue. Some homeowners notice increased heating or cooling costs before they spot the actual damage, which makes sense given how much air volume moves through a compromised seal.
In Lakewood's mild climate, we don't get brutal cold snaps, but the marine layer and salt air still wear seals faster than inland areas. High humidity near the coast also encourages mold growth in damaged seals.
A weather stripping replacement typically costs between $150 and $400 installed, depending on whether you need just the sides and top, or if the bottom seal requires replacement too. Bottom seals often run $50 to $150 extra because they take more labor and wear out faster from foot traffic and debris.

A small gap in your weather stripping might seem harmless, but it compounds. Over a heating or cooling season, that draft adds 10 to 15 percent to your energy costs. Moisture that seeps in can rot the bottom of your door frame and corrode hardware. Insects and rodents find their way into your garage, then sometimes into your home.
If you're planning a garage door replacement or considering insulation upgrades, weatherproofing should be your first step. We have a detailed post on garage door insulation in Lakewood that explains how seals and insulation work together.
Inspect your weather stripping now, especially if your door is over five years old. Look at the bottom seal where it meets the concrete threshold. Check for visible gaps on the sides. If anything looks cracked or loose, reach out.
Garage Door Lakewood handles weather stripping replacements as a standalone service or bundles them with routine maintenance. We use commercial-grade rubber and vinyl that holds up to Lakewood's coastal environment. Installation includes removing old material, cleaning the frame, and sealing everything properly so drafts don't return in a few months.
Don't let a small seal problem turn into energy waste and pest problems. Call (510) 694-4071 or get a same-day estimate today.
How long does weather stripping last? Quality rubber and vinyl stripping typically lasts 5 to 7 years in Lakewood's coastal climate. UV exposure and temperature changes accelerate wear. Annual inspection helps you catch deterioration early.
Can I replace weather stripping myself? Yes, but it requires careful measurement, clean frame prep, and proper adhesive or fastening. Most DIY attempts end with gaps or peeling seals. Professional installation ensures a tight fit and warranty coverage.
What's the difference between weather stripping and a bottom seal? Weather stripping runs along the sides and top of your door frame. Bottom seal (or threshold seal) sits at the base where the door meets the concrete. Both are essential for a complete seal.
Does weather stripping help with insulation? It reduces air infiltration and heat loss, but it's not true insulation. If energy savings are your goal, pair weather stripping with an insulated door. We compare both options in our garage door insulation article.
Will new weather stripping stop pests from entering? Properly installed seals eliminate the gaps pests use to enter. A tight bottom seal is especially important since rodents often squeeze under doors. Combined with threshold sealing, it's very effective.
