Weather Stripping & Seals Gap in Sequim: How to Spot and Fix It
7 min read
A customer called last Tuesday from the Dungeness area asking why cold air was pouring under her garage door, even though the seal looked fine from inside. Turns out, her bottom seal had compressed over three winters. Weather stripping and seals in Sequim wear faster than most places because of moisture and temperature swings. A visible gap means drafts are already getting through, energy is leaking out, and pests may follow. The fix is straightforward: identify where the gap is, measure it accurately, and replace the seal before next winter.
Where Gaps Show Up Most
The bottom seal takes the hardest beating. It sits on concrete, gets walked on, and absorbs water during our rainy months. Over time, rubber hardens and shrinks. You might see daylight under the door when it closes, or feel cold air moving into the garage. The threshold (the strip at the base where the door meets the floor) can also crack or pull away from the frame.
Side seals and top seals fail too, but less often. Look for crumbling rubber, visible separation from the frame, or a dark line where the seal used to sit tight against the metal. If you can slide a credit card into the gap, cold air and moisture are definitely getting through.
Why This Matters in Our Climate
Sequim sits in a rain shadow, but we still get 16 inches of annual precipitation. That moisture creeps into garages through every gap. Warm, humid air inside meets cold surfaces, and condensation forms. Over weeks and months, that dampness encourages rust on springs, tracks, and hardware. Energy bills climb because your furnace works harder to heat a leaking space.
Pests also use these gaps. Insects, spiders, and rodents squeeze through surprisingly small openings. A compressed or missing seal becomes an open invitation.

Measuring and Replacement Cost
Measure the gap width and length before you call anyone. A quarter-inch gap is minor. A half-inch or more needs attention. The bottom seal usually runs 16 to 18 feet on a standard two-car door. Replacement cost ranges from $150 to $400 for materials and labor, depending on seal type and whether the frame needs repair too.

Don't assume the cheapest seal is the best choice. Heavy-duty rubber lasts longer than thin vinyl. If your frame is bent or the track is misaligned, the new seal will compress again quickly. That's why an in-person inspection matters before you invest.
DIY Versus Calling a Pro
Replacing a bottom seal yourself is possible if the frame is straight and the door closes evenly. You'll need a screwdriver, the right seal profile (get a sample from the hardware store), and patience. The door must be disconnected from the opener for safety.
However, if the frame is dented, the door is sagging, or you're unsure about alignment, call a technician. A misaligned door will destroy a new seal within months. We've replaced seals three times for customers who tried the DIY route without fixing the underlying issue first.
Our team at Garage Door Sequim handles the diagnosis for free. We check door balance, track condition, and seal fit before recommending a solution. That clarity saves you money in the long run.
Seasonal Timing Matters
Fall is the worst time to discover a gap. Spring and early summer are ideal for replacement because you'll use the garage door less and weather is dry. Scheduling in June gives you a fresh seal before the rainy season returns.

Frequently Asked Questions
How long do garage door seals last? Most rubber seals last 3 to 5 years in our climate. Heavy-duty versions may stretch to 7 years with good maintenance. Vinyl seals wear faster and typically need replacement every 2 to 3 years.
Can I replace just the bottom seal, or do I need to do all of them? You can replace just the bottom seal if other seals are still firm and fit snugly. However, if the door is old (10+ years), consider replacing all seals at once to ensure even protection and appearance.
What's the difference between weather stripping and a door seal? Weather stripping is the rubber or foam material itself. A seal or gasket is the complete assembly, including the rubber insert and any metal or plastic retainers. Both terms are used interchangeably in the garage door industry.
Will a new seal fix my draft problem if my door is misaligned? No. If the door sags or the frame is bent, a new seal will compress unevenly and fail quickly. Alignment must be corrected first for the seal to work properly.
How much does weather stripping replacement cost near me? Cost typically runs $150 to $400 for a standard two-car door, depending on seal type and labor. Get a free estimate from our team to know the exact price for your situation.
