A drafty garage door wastes energy, lets cold air in, and ruins the seal around your threshold. Weather stripping and seals wear out faster than most homeowners realize, especially here in Danville where temperature swings between summer heat and winter chill stress the materials year-round. Replacing worn seals stops drafts, lowers heating costs, and protects what's stored inside.
After 15 years on the trucks, I've seen thousands of garages losing money through bad seals. Most people don't notice until their energy bills spike or they spot water pooling near the bottom of the door. By then, the damage is done. The good news? This fix is straightforward, affordable, and makes an immediate difference.
Weather stripping comes in three main spots: the top header seal, the side jamb seals, and the bottom seal. The bottom seal takes the most abuse because it sits closest to the ground, exposed to dirt, moisture, and foot traffic. Over time, rubber hardens and cracks. Foam compresses and stops sealing. Metal thresholds bend or separate from the concrete.
When seals fail, cold drafts sneak in. Moisture follows. In Danville's climate, that means your heating works overtime in winter, and humidity creeps into the garage, damaging tools, boxes, and vehicles. A single bad bottom seal can cost you $15 to $30 per month in wasted energy during colder months.
The threshold itself is a common culprit. It sits where the garage door meets the ground, and if it's bent, cracked, or installed incorrectly, no amount of new weather stripping fixes the draft. I recommend inspecting both the seal and the threshold together.
Look for visible cracks, gaps, or discoloration in the rubber or foam. Run your hand along the seals on a cold day. If you feel air movement, they're compromised. Check the bottom seal especially. If it's hard, brittle, or separated from the door, replacement is overdue.
Another telltale sign? Water pooling on the garage floor after rain, especially along the edges near the door. That means the seal isn't doing its job. You might also notice your garage stays cold longer than it should, even with the door closed.

Some homeowners think they can swap out weather stripping themselves. It's tempting because the materials are cheap. But here's what I've learned: improper installation causes more problems than it solves. If the seal isn't cut precisely or compressed evenly, you'll still have drafts. If the threshold isn't level, water still pools.
Professional technicians have the right tools to remove old adhesive, measure the opening exactly, and install new seals so they sit flush and seal tight. We also inspect the bottom seal track and threshold to make sure nothing else is causing the draft. Read more about why weather stripping stops working and how to fix it properly.
The cost difference between DIY and professional work is smaller than you'd think, especially when you factor in the risk of getting it wrong. A botched installation might cost you more in wasted energy than the repair itself.
The cost depends on the type of seal and how much needs replacing. Bottom seals run $150 to $350 installed. Side and top seals might add another $100 to $200. If the threshold needs replacing, budget an extra $200 to $400. Most jobs finish in under an hour, so same-day service is standard.

Once new seals are installed, keep them clean. Remove debris and dirt from the bottom seal track quarterly. Don't let leaves or trash pile up around the door. In Danville's hot summers, the rubber can dry out faster than normal, so a quick visual check twice a year saves headaches.
New seals typically last 5 to 7 years, depending on weather and use. Mark it on your calendar. When they start looking worn, get them replaced before drafts become a problem.

How long do garage door weather seals last? Rubber and foam seals typically last 5 to 7 years in Danville's climate. Exposure to UV rays, temperature swings, and moisture accelerates wear. Inspect annually and replace when you spot cracks or hardening.
Can I replace weather stripping myself? You can buy DIY kits, but professional installation ensures proper fit and adhesion. Mistakes often leave gaps, defeating the purpose. Our technicians finish jobs in under an hour for a small cost difference.
What's the difference between a seal and a threshold? The seal is the rubber or foam strip that compresses against the door. The threshold is the metal or rubber piece at the base where the door meets the concrete floor. Both must work together to stop drafts.
Does weather stripping really save energy? Yes. A bad bottom seal can waste $15 to $30 per month in heating costs during winter. New seals pay for themselves within a few months of cooler weather.
