A customer called last Tuesday asking why their heating bill had jumped forty dollars a month. We drove out to their Manzanita home, pulled up the garage door halfway, and found the culprit immediately: the bottom seal was cracked and peeling away from the frame. Cold air was pouring in like water through a broken dam. One afternoon of work replacing the weather stripping and seals, and their draft problem vanished. That's what we mean by fixing it right the first time.
Weather stripping and seals are the unsung heroes of garage door performance. They stop drafts, keep moisture out, and hold your conditioned air inside. Most homeowners ignore them until energy bills spike or water starts pooling near the threshold during our coastal rains. By then, the damage is already done.
Our Oregon coast climate is brutal on rubber and foam. Rain, salt air, UV exposure, and constant temperature swings break down seals faster than in drier regions. The bottom seal typically lasts five to seven years before it hardens, cracks, or pulls away from the door completely. Side and top seals fare a bit better, but they're not immune.
Thermal cycling makes it worse. Your garage swings from cold mornings to warmer afternoons. That expansion and contraction works the seal like a rubber band until it loses its grip. Add mud, debris, and the occasional impact from bumping the door, and failure accelerates.
The threshold (the metal or vinyl strip at the base where the door meets the floor) also deteriorates. It bears the weight of the closing door repeatedly and collects standing water. Corrosion and warping follow quickly if the seal above it fails.
Look for these red flags. A visible gap between the door and frame means air is moving through freely. You might see daylight around the edges in direct sunlight. Feel for drafts with your hand near the bottom and sides on a windy day. Water stains or pooling inside the garage after rain point to a failed bottom seal. Some customers notice condensation on windows or a musty smell that wasn't there before.
Energy loss is harder to spot visually but shows up on your utility bill. If your heating costs jumped unexpectedly and you can't blame your furnace, your seals are likely the culprit. A professional inspection catches problems before they become expensive.

The bottom seal is the most critical piece. Rubber and vinyl are the standard materials. Rubber lasts longer but costs more. Vinyl is cheaper and easier to install, though it doesn't hold up quite as long in harsh weather. We typically recommend marine-grade rubber for homes near the coast because it resists salt air better.
Side seals and top seals are usually foam or rubber bulbs that compress when the door closes. They fill the gaps between the door panels and the frame. Top seals see less traffic, so they last longer than bottom seals. Side seals can wear unevenly if your door isn't perfectly aligned.
The threshold is a separate component that works with the bottom seal. A damaged threshold can undermine even a brand-new seal. Both often need replacement together for the best results.
If your door is also losing energy through poor insulation, we've written a detailed guide on what R-value your garage door needs in Manzanita to maximize efficiency.
A bottom seal replacement typically runs $150 to $300 depending on the door size and seal type. Side and top seals add another $100 to $150 each. If the threshold needs replacement, budget an additional $200 to $400. Most jobs are simple enough that we can finish them in under two hours, which is why we offer same-day estimates and quick turnarounds.
Don't skip the threshold. A seal alone won't stop water if the threshold is warped or rusted. We inspect both during every service call and recommend replacing them as a pair. Your cost is lower upfront when we do it together rather than waiting six months and calling us back.
Labor varies slightly based on whether your door is aluminum or steel and whether we need to remove and reinstall panels. Get a free estimate from Garage Door Manzanita to see your exact cost. Schedule a free quote by calling us or filling out our online form. We'll inspect your seals, measure your door, and give you a number with no surprises.
Once new seals are installed, keep them healthy. Clean the bottom of your garage door monthly, especially after rain or storms. Remove debris from the threshold so water doesn't pool. Check the seals visually twice a year (spring and fall). A small crack can be sealed temporarily with weatherproof caulk, but plan for full replacement within a few months.
Lubricate moving parts of your garage door system annually. This reduces strain on seals and extends their life. Our maintenance guide covers the full routine you can handle yourself.
Keep your door aligned. A misaligned door puts pressure on seals unevenly and wears them faster. If your door sticks, binds, or closes unevenly, have it inspected before seals fail.
Weather stripping and seals aren't glamorous, but they're fundamental to a working, efficient garage door. Fix them now, and you'll sleep better knowing your garage stays dry and your heating bill stays reasonable.

How long do garage door seals last? Bottom seals typically last five to seven years in our coastal Oregon climate. Side and top seals may last seven to ten years. Salt air, temperature swings, and moisture accelerate wear. Inspect annually and replace when you see cracks or gaps.
Can I replace weather stripping myself? Yes, if you're handy. Bottom seals and side seals are straightforward. You'll need a screwdriver, a new seal kit, and about an hour. Thresholds require more precision. If you're unsure, call a professional to avoid misalignment and wasted material.
Why is my garage door leaking water? A failed bottom seal or warped threshold is the usual cause. Water pools against the door during heavy rain and finds gaps. Inspect both the seal and threshold. Replace whichever is damaged. Ensure the floor slopes slightly away from the garage to encourage drainage.
What's the difference between rubber and vinyl seals? Rubber is more durable and handles coastal weather better but costs more. Vinyl is affordable and adequate for many situations but degrades faster in UV and salt exposure. For Manzanita homes, we recommend rubber seals for longevity.
How much does a weather stripping replacement cost? A bottom seal runs $150 to $300 installed. Side and top seals add $100 to $150 each. Threshold replacement is $200 to $400. Full seal and threshold replacement typically costs $400 to $600 depending on door size and materials.
