Here's what most homeowners don't realize about weather stripping and seals: they wear out silently, long before you notice a draft. You might blame your heating bill on the weather, but a failing bottom seal or deteriorated threshold is often the real culprit. In Fall City, where we get plenty of rain and temperature swings, your garage door's weather stripping takes a beating. Most people don't check it until they feel cold air seeping in.or worse, water pooling on the garage floor.
I've been running Fall City Garage Doors for years, and I've seen homeowners lose hundreds of dollars in wasted heating and cooling because they skipped this one maintenance step. The good news? It's one of the easiest, most affordable fixes we offer.
Garage door seals experience constant movement. Every time your door opens and closes, the rubber compresses, stretches, and flexes. Over time.typically 3 to 5 years in our Pacific Northwest climate.that rubber hardens and cracks. UV exposure, moisture, and temperature changes accelerate the breakdown.
The bottom seal takes the most punishment. It sits closest to the ground, where it collects dirt, absorbs water, and bears the full weight of the door's downward force. When it fails, you get a draft. When it really fails, you get water damage.
The threshold seal is equally important. It's the horizontal strip running along the garage floor where the door sits when closed. A compromised threshold allows rain and groundwater to seep underneath, creating moisture problems that can spread to your drywall, insulation, and stored items.
Walk outside on a sunny day and look at your closed garage door from the side. Can you see daylight between the door and the frame? That's a sign your side seals are deteriorating.
Check the bottom seal next. Does it look cracked, brittle, or flattened? Press your fingers against it.good rubber should have some give. If it feels hard as plastic, it's past its prime.
After a rainstorm, inspect your garage floor and walls near the base of the door. Water stains or dampness indicate your seals aren't doing their job. This is especially critical in Fall City, where moisture and rust can damage your door frame and springs faster than in drier regions.

Many homeowners think, "I'll wait until it gets worse." That's the wrong math. A failing seal costs you money every single month in wasted energy. Studies show that a degraded bottom seal can increase your heating costs by 10,15% during winter.
Worse, water intrusion leads to rust on your springs and brackets.and spring replacement in Fall City typically runs $200,$400, depending on the door size. We've also seen moisture damage lead to panel replacement costs that easily exceed $500. A $100,$200 seal replacement done today prevents a $500+ repair next year.
If you're already thinking about maintenance, review our preparation guide for cold weather, which covers seals as part of a broader strategy.

DIY seal kits exist, but they often don't fit right. A poor fit leaves gaps.which defeats the entire purpose. Our team measures your specific door model and ensures the seal compresses evenly when the door closes. That's the difference between a seal that lasts 5 years and one that lasts 3.

Fall City's weather is tough on garage doors. Don't let a small problem become an expensive one.
How long do garage door seals last? Quality weather stripping lasts 3,5 years under normal conditions. In Fall City's wet climate, expect the lower end. Regular inspection helps you catch failure early.
Can I replace weather stripping myself? You can, but professional installation ensures a tight seal. Gaps from improper fitting waste energy and allow moisture in. We recommend professional service for best results.
What's the difference between a bottom seal and a threshold seal? The bottom seal is the rubber attached to the door itself. The threshold seal is a strip on your garage floor. Both are needed for complete protection against drafts and water.
