Your garage door's bottom seal is doing heavy lifting you probably don't see. It's the rubber strip between your door and the concrete threshold, and it's the difference between a sealed space and a drafty mess. When that seal fails, cold air pours in, your heating bill climbs, and pests find an easy route indoors.
That rubber strip running along the bottom of your garage door performs three critical jobs. First, it seals the gap between your door and the threshold, stopping drafts from sneaking into your garage and the rest of your home. Second, it acts as a weather barrier against rain, snow, and debris that would otherwise pool on your garage floor. Third, it keeps out spiders, rodents, and insects that exploit even tiny openings.
After 15 years on service calls in Burbank, I've seen what happens when homeowners ignore this detail. A worn bottom seal costs you money every month in lost heating and cooling. It also lets moisture creep in, which damages concrete and invites rust to settle on tools and vehicles stored inside.
A draft starts small. Your weather stripping and seals wear down from friction, UV exposure, and temperature swings that crack rubber over time. The seal shrinks or peels away from the door frame, leaving a gap. Cold air rushes through that gap in winter, and humid air seeps in during summer.
You'll notice drafts first around the edges and threshold. If you place your hand near the bottom of the door on a windy day, you'll feel air movement. Some Burbank homes also report a slight whistling sound when wind hits the garage. These are signs your bottom seal needs attention now, not later.
The cost of ignoring this is real. A failing seal can add 10 to 15 percent to your monthly heating bill if your garage is attached to your home. That's money going straight to heating outdoor air.

Not all bottom seals are the same. The most common type is the rubber blade seal, which hangs from the bottom of your door and compresses against the threshold when closed. These are affordable and easy to replace, but they wear out faster than other options.
Another option is the bulb seal, which is thicker and shaped like a bulb when compressed. It offers better sealing and lasts longer, though it costs a bit more upfront. Some commercial doors use drop seals or threshold seals that create a double barrier against drafts.
At Burbank Garage Doors, we help homeowners pick the right seal for their door type and climate. Your choice depends on how often you open and close the door, your local weather, and your budget. Schedule a free quote to discuss which seal works best for your garage.
Most rubber seals last 3 to 5 years in Burbank's climate. You'll notice visible cracks, hardening, or gaps before they fail completely. If your seal is cracked, peeling, or no longer compresses fully when the door closes, replacement is overdue.
Seasonal temperature swings in Washington take a toll on rubber. Winter cold makes seals brittle, and summer heat accelerates breakdown. If you've been delaying maintenance, now is a smart time to act. Learn more about the common signs and costs of replacement to plan your budget.
You can inspect your seal yourself. Close the door and look for visible gaps, cracks, or hardening. Try the flashlight test: shine a light around the edges from inside the garage. If you see light coming through, your seal has failed.
Replacement is straightforward for homeowners with basic tools, but improper installation can leave gaps and drafts. A professional can ensure your new seal sits flush against the threshold and compresses evenly across the entire width of the door. Poor installation often costs more in wasted energy than professional labor would have.
Once you've replaced your weather stripping and seals, keep them clean and free of debris. A quick sweep of the threshold every month prevents dirt from building up and creating gaps. In winter, clear snow and ice away from the seal to prevent damage.

What's the difference between a bottom seal and a threshold seal? A bottom seal (or blade seal) attaches to the bottom of your garage door and compresses against the concrete threshold when closed. A threshold seal sits on top of the concrete itself. Many homes benefit from both working together to eliminate drafts completely.
How much does weather stripping and seal replacement cost in Burbank? Costs typically range from $150 to $400, depending on your door size and seal type. A basic rubber blade seal is cheaper; heavier bulb seals cost more but last longer. Call (509) 283-8247 for an exact estimate based on your door.
Can I replace the bottom seal myself, or should I hire a professional? You can do it yourself if you're handy with basic tools. Most seals pop out and snap back in. Professional installation ensures a perfect fit and eliminates drafts. If you're unsure, a technician can complete the job same-day.
Why does my garage feel cold even after I sealed the bottom? Cold air may be entering through side seals or the top of the door. A full weather stripping inspection catches all leak points. Ask your technician to check the entire door frame, not just the bottom.
How often should I replace my weather stripping and seals? Plan for replacement every 3 to 5 years in Burbank's climate. If you notice cracks, hardening, or visible gaps sooner, don't wait. Catching wear early prevents energy loss and bigger repair costs.
