A customer called last Tuesday in a panic. Her electric bill had jumped $200 in one month. She assumed her furnace was failing. After a quick inspection, we found the culprit: a deteriorated bottom seal on her garage door, letting cold air pour into the attached garage and bleeding into her home. Weather stripping and seals in Burbank are your first line of defense against drafts, energy waste, and pest infiltration. When they fail, you notice it fast.but most homeowners don't know what to look for until damage spreads.
Garage door seals take a beating. They expand and contract with temperature swings. In Burbank winters, that cycling accelerates wear. UV exposure during summer hardens the rubber. Heavy use compresses the material over time. Most seals last 5,8 years before they stop doing their job effectively.
Here's what happens when seals fail: cold drafts enter the garage. If your garage is attached to your home.and most are.that draft travels through walls and into living spaces. Your heating system works overtime. Rodents and insects find gaps to slip through. Moisture accumulates, encouraging mold growth in corners and along the threshold where the door meets concrete.
I've seen homes lose 15,20% of heating efficiency due to a compromised bottom seal alone. That's not theoretical. That's real money leaving your house every month.
Walk around your closed garage door on a cold day. Feel along the edges with your hand. You should feel minimal air movement. If you detect a strong draft near the bottom seal or side jambs, you've found your problem.
Look for these warning signs:
- Visible gaps between the door and frame (especially at corners) - Cracked, hardened rubber that doesn't bounce back when pressed - Missing chunks of seal material - Water pooling inside the garage after rain - Daylight visible around the threshold area
Don't ignore these. A failing seal is a gateway issue.it leads to imbalance problems and opener strain. We've written a detailed guide on balance adjustment that explains how poor seals contribute to mechanical wear.
Your garage door has multiple seal points. Knowing them helps you diagnose problems faster.
Bottom seal (threshold). This is the strip that runs along the floor. It takes the most abuse and fails first. Replacement is straightforward and affordable.
Side seals (jamb seals). These run vertically on both sides. They prevent lateral drafts and keep insects out. Damage here is less common but still critical.
Top seal. This sits above the door when closed. It's usually tougher but can harden and crack over time.
Header seal. The gasket around the frame opening. Often overlooked but essential for complete weatherproofing.

Can I replace weather stripping myself? While possible, garage door removal and seal installation require mechanical skill. Springs are dangerous. Professional installation is safer and often more durable.
How long do garage door seals last? Quality seals typically last 5,8 years depending on climate and usage. Burbank's temperature swings can accelerate wear. Annual inspection helps catch problems early.
Will new seals reduce my heating bill? Yes. A properly sealed garage door can reduce heating costs by 10,15% in attached garages. Energy savings often recover the cost within one heating season.
What's the difference between a bottom seal and a threshold seal? They're the same thing.different names for the weatherstripping that runs along the garage floor where the door closes.
