If your garage feels drafty, lets in rain, or your energy bills spike in winter, worn weather stripping & seals are likely the culprit. A damaged bottom seal or threshold can cost you hundreds annually in wasted heating and cooling.plus invite pests and moisture damage. The good news: fixing this is affordable and often preventable with routine maintenance.
Weather stripping and seals take a beating in Lafayette's mild but variable climate. Rubber and vinyl degrade from sun exposure, temperature swings, and repeated door cycles. Most seals last 3,5 years before they crack, harden, or separate from the frame.
Common warning signs include:
- Visible gaps around the door frame or bottom - Light streaming in around edges on a sunny day - Drafts you can feel with your hand - Water pooling inside after rain - Pest droppings or debris near the threshold - Higher heating/cooling costs with no other explanation
A damaged bottom seal is especially problematic because it's the first line of defense against weather. Unlike a crack in drywall you can patch later, a failing threshold needs attention before moisture penetrates your garage floor and framing.
Check our garage door maintenance checklist for a step-by-step inspection routine that catches these issues early.

How long does weather stripping last? Most rubber and vinyl seals last 3,5 years in California's climate. Inspect annually and replace when you spot cracking, hardening, or gaps.
Can I replace seals myself? Yes, if only the bottom seal is damaged and you're comfortable with basic tools. Side and top seals are trickier; professional help ensures proper fit and alignment.
What's the difference between a seal and weatherstripping? Weatherstripping is the material that fills gaps around the door frame. A seal (or bottom seal) is the rubber strip on the bottom of the door itself. Both serve the same purpose: block drafts and weather.

How much can I save by fixing seals now? Depending on your region and season, a well-sealed garage saves $10,$30 monthly on heating/cooling. Over a year, that's $120,$360.often paying for the repair itself.
