Weather stripping and seals do one job: block air, dust, and pests from sneaking into your garage. A worn bottom seal lets drafts pour in. Damaged threshold seals waste energy and invite rodents. The fix is straightforward: replace them before they fail. Most homeowners ignore this until they notice cold spots or see light creeping under the door.
Our Texas climate is brutal on rubber and foam. Summer heat, winter cold snaps, and sudden temperature swings cause materials to crack and shrink. A seal that works fine in spring may harden and split by July. The bottom seal of your garage door takes the worst beating. It flexes every time the door opens and closes, rubs against the concrete floor, and absorbs moisture from humidity.
After three to five years, most weather stripping loses its grip. You'll notice gaps widening, air leaking around edges, or visible daylight under the door. That's your signal to act.
Skipping maintenance on weather stripping and seals costs more than the repair itself. Air leaks force your HVAC system to work harder, especially if your garage is conditioned or connected to your home. Energy bills creep up. In Mckinney summers, that means cooling loss. In winter, warmth escapes.
Beyond cost, gaps invite pests. Rodents, insects, and spiders use those openings as highways into your garage. Once inside, they move toward your home. A $200 seal replacement beats a $2,000 pest control nightmare every time.
Weather stripping also protects your door itself. Water intrusion accelerates rust on metal frames and warping on wooden panels. Proper seals keep moisture out, extending your door's lifespan by years.

When we talk about weather stripping and seals, most jobs involve two components. The bottom seal is the rubber or vinyl strip that hangs from the bottom edge of your door. It compresses against the floor as the door closes. Over time, it hardens, cracks, or tears.
The threshold is the weatherproofing along the sides and top of the door frame. Side seals prevent drafts from entering along the vertical edges. Top seals block light and air from leaking above the door. All three wear at different rates depending on sun exposure and usage.
Replacing them requires the right materials and technique. A poor fit leaves gaps. Too much compression wastes energy on friction. We size each seal to your specific door frame and opening. That attention matters. A mismatched bottom seal won't sit flush against the concrete, defeating the purpose.

How long do weather stripping and seals last? Most garage door seals last three to five years in Mckinney's climate. Texas heat accelerates deterioration. Inspect them annually and replace them when you see cracks, hardening, or visible gaps.
Can I replace weather stripping myself? Yes, basic bottom seal replacement is a DIY task if you're handy. Measure twice, buy the correct profile, and install carefully. Side and top seals are trickier. Improper installation leaves gaps that defeat the purpose.
What's the difference between a bottom seal and a threshold? The bottom seal hangs from the door and compresses against the floor. The threshold is fixed weatherproofing along the frame edges. Both prevent drafts, but they wear and fail independently.
Why does my garage door draft in winter? Worn side seals and top seals let cold air pour in as temperature differences increase. Winter cold also makes rubber stiffer and more prone to cracking. A complete seal inspection catches all leak points.
How much does weather stripping cost? Prices vary by door size and seal type. A basic bottom seal replacement typically costs less than $300. Get a free estimate to know your exact cost.
