Most homeowners don't think about their garage door until something goes wrong. But if you're losing heat in winter, seeing daylight under the door, or noticing bugs getting in, your weather stripping and seals are already failing. On Camano Island, where we get rain, salt air, and temperature swings, a compromised bottom seal isn't just an annoyance. It's money walking out the door and moisture creeping in.
Camano Island sits in the Puget Sound region with a marine climate. That means wet winters, cool springs, and high humidity year-round. Your garage door is one of the largest openings in your home. If the weather stripping and seals are worn, drafts form, and you're heating the outdoors instead of your space.
A failing threshold or bottom seal allows:
- Cold air and moisture to enter, Heated air to escape (costing real money on utility bills) - Pests, insects, and debris to get inside, Water pooling near your foundation or garage floor
Most people assume this is just how garages are. It's not. A properly sealed garage door keeps your attached home warmer, protects your vehicles and stored items, and prevents costly water damage.
Weather stripping degrades for predictable reasons. UV exposure, repeated opening and closing, temperature cycling, and salt air (especially on the island) all break down rubber and foam materials. Most seals last 5 to 7 years before they crack, shrink, or lose their grip.
Once the bottom seal fails, you'll notice:
- Light visible under the door, Drafts you can feel with your hand, Water stains or puddles on the garage floor after rain, Higher heating or cooling bills, Insects or rodents finding their way inside
The cost to replace weather stripping and seals is modest compared to the damage of ignored moisture or energy waste. A new bottom seal or full threshold replacement typically runs between $150 and $400, depending on your door type. That investment pays for itself within one heating season on the island.

Not all seals are the same. Your garage door may have a rubber bottom seal, foam weather stripping around the sides, or a combination threshold system. Each serves a purpose.
Bottom Seal (Sweep) The rubber or vinyl strip at the base of the door that makes contact with the floor. This is the most critical seal and the first to fail.
Side and Top Stripping Foam or rubber gaskets that run along the sides and top of the door frame. They fill gaps between the door and frame, stopping drafts from the sides.
Threshold A raised section of the floor or a mounted seal that creates a barrier for water and pests. On Camano Island, a proper threshold is essential during heavy rain.
If you're unsure which type your door has or what needs replacing, we can assess it during a free estimate. Most doors benefit from a complete seal replacement, not just one component.
You can extend the life of your weather stripping by keeping it clean and dry. Remove debris from the threshold. Don't let water pool around the base of the door. If you notice the seal starting to harden or crack, call early rather than waiting for complete failure.

How often should I replace garage door weather stripping? Most seals last 5 to 7 years on Camano Island. Salt air and moisture accelerate wear. Inspect yours annually and replace when you see cracks, hardening, or visible gaps.
Can I replace weather stripping myself? The bottom seal can be a DIY job if you're handy, but side and top stripping often require precision. Improper installation leaves gaps. We recommend professional installation for best results and warranty coverage.
What's the difference between a bottom seal and a threshold? A bottom seal is attached to the door itself and moves with it. A threshold is fixed to the floor or frame and provides a permanent barrier. Many doors use both for maximum protection.
Will new weather stripping lower my heating bill? Yes. A properly sealed garage reduces draft and heat loss, especially if your garage is attached to your home. You'll see savings during colder months, typically recouping the cost within one season.
How do I know if my seals are failing? Look for light under the door, feel for drafts, check for water stains on the floor after rain, or notice insects inside. Any of these signs means it's time for an inspection and likely replacement.
