A customer called last Tuesday asking why her energy bills spiked in June. We drove out to her Encinitas home, checked her garage door, and found the bottom seal nearly torn in half. Hot air was pouring in unchecked. She'd spent weeks cooling a space that was leaking conditioned air faster than the system could replace it. Weather stripping and seals are not glamorous, but they're the difference between comfort and waste.
Your garage door is a thermal barrier. If the seals fail, your garage becomes a heat sink. In Encinitas, where summer temperatures climb and your air conditioning runs hard, a compromised bottom seal or threshold can cost you real money every month.
Weather stripping serves one job: it closes gaps. The bottom seal stops air and water from creeping under the door. The side seals press against the frame. The top seal caps the opening. Together, they create a barrier. When any one fails, drafts get in. Insects follow. So does dust, noise, and whatever the coastal weather throws at you.
We've seen doors with seals so worn they look like frayed rope. That's what happens when UV exposure, temperature swings, and salt air work on rubber and vinyl for five to seven years without replacement. Encinitas homeowners often don't realize how fast our climate ages these materials.
Look at your bottom seal first. Get down on your hands and knees. Shine a flashlight under the closed door. Can you see daylight? That's your answer. A healthy seal should touch the threshold with gentle, even pressure.
Check the sides next. Run your hand along the rubber strips on both sides. They should feel firm and flexible. If they're cracked, hard as plastic, or peeling away from the frame, they need replacing. Side seals that have shrunk or warped will cause the door to rattle when the wind picks up.
The threshold itself tells a story. If it's crumbling, split, or visibly sunken, air will rush past it no matter how good your bottom seal is. We often find that homeowners replace the seal but leave a damaged threshold in place. That's money wasted.
Listen for drafts too. On a breezy day, stand inside your garage with the door closed. Do you hear whistling? That's air moving through gaps. You shouldn't hear anything.
Most bottom seal replacements run between $150 and $300 installed, depending on your door model and whether the threshold needs work. Side seals typically add another $100 to $150 per side. A full seal kit with professional installation usually lands in the $400 to $600 range for an average residential door.
That sounds like money, but compare it to the cost of running your AC against open gaps all summer. A homeowner paying $180 a month for cooling could recoup the seal cost in three or four months if leaks are significant. We always provide a same-day estimate so you know exactly what you're paying before we start.

You can buy weather stripping at the hardware store. Adhesive-backed foam tape costs ten dollars. It sounds tempting. Here's what happens: the adhesive doesn't stick well to dusty, salty Encinitas air. The foam compresses under the door's weight. By fall, it's peeling off or flattened to nothing.
Professional seals use materials built for garage doors. They're compression-rated, UV-resistant, and designed to handle repeated opening and closing cycles. Our team installs them with the door's geometry in mind, not just slapped on. That's the difference between a temporary fix and one that lasts five to seven years.
If your door is part of a maintenance routine, seals should be inspected every two years. If you've never had them serviced, now is the time. Coastal weather ages them faster than inland homes experience. Our garage door maintenance guide covers seasonal checks that catch seal problems early.
If you can see light under your door or feel cold air drafting in winter, don't wait. If your threshold is damaged, your seals are torn, or your door has been neglected for years, call a pro. A quick inspection takes 15 minutes. We'll tell you exactly what needs replacing and whether other components are affected. Sometimes a worn seal is a sign that something else is misaligned or damaged.
For doors that are difficult to access or have custom frames, DIY sealing becomes risky. You might damage the door trying to fit standard seals. Our team knows how to handle every type of installation. We also check your garage door springs and openers while we're at it, making sure everything works as a system.

A functioning seal is invisible. You don't notice it until it fails. That's why we treat every installation like it matters, because it does.
How long do weather stripping and seals last? Most seals last five to seven years in Encinitas. Coastal UV exposure and salt air accelerate wear. We recommend inspections every two years and replacement when seals show cracks, shrinkage, or hardening.
Can I replace just the bottom seal without replacing side seals? Yes, you can replace seals individually. However, we often find that if the bottom seal has failed, side seals are aging too. We'll inspect all of them and recommend a full kit if cost-effective over time.
What's the difference between a threshold and a bottom seal? The threshold is the metal or rubber strip that runs along the bottom of the frame. The bottom seal is the rubber gasket that hangs from the door and compresses against the threshold. Both must be in good condition to block drafts and water.
Will new seals improve my garage temperature? Yes, especially in summer. Seals prevent hot air from entering and conditioned air from escaping. Most customers notice a difference within one billing cycle if they've been running AC against significant leaks.
Do you offer same-day service for seal replacement? We do offer same-day estimates and often can schedule installation within 48 hours. Call 619-639-1436 to check availability and get your free quote today.
