Built for 36 Inches of Rain
Garage Door Weather Seal Replacement in Tigard, OR
Weather seal replacement renews the rubber barrier between your garage and Oregon weather: the bottom seal, side and top weatherstrip, and thresholds. Small parts that decide whether your garage stays dry.
- Typical market cost: $80 to $200
- Water, drafts, and rodents blocked
- Often same-visit with any repair
Why Seals Matter More Here Than Most Places
Washington County averages roughly 36 to 40 inches of rain a year, nearly all of it in the eight months when your garage contents least want to be damp. The bottom seal is the only thing between that water and your slab. Once it cracks or flattens, the sequence is predictable: a wet stripe inside the door, then rust starting on the door’s bottom section, then that musty garage smell that never quite leaves cardboard boxes.
The bottom two feet of a garage door system takes almost all the weather damage we see in Tigard, Metzger, and Aloha: rusted bottom sections, corroded track feet, and frayed cable ends all start with splash-back a healthy seal would have shed.
The Four Seals On Your Door
| Seal | What it does | Typical failure sign |
|---|---|---|
| Bottom seal (astragal) | Compresses against the slab across the door width | Daylight or a wet line under the closed door |
| Side weatherstrip | Seals the vertical gaps at the jambs | Drafts, wind noise, wasps exploring the gap |
| Top seal | Closes the header gap | Rain streaks inside the top section |
| Threshold | Raised floor barrier for sloped driveways | Water flowing in despite a good bottom seal |
What We Do On a Seal Visit
- Measure the gap pattern with the door closed. Uneven daylight sometimes means the door is out of level, a balance issue rather than a rubber issue, and we say so.
- Replace the bottom seal in the correct retainer style, T-end, bead, or bulb, matched to your door brand.
- Renew side and top weatherstrip with UV-stable material, nailed or screwed to the jambs with proper compression.
- Add a threshold ramp where driveway slope pushes water toward the garage.
- Check the bottom section and track feet for the early rust the old seal let in.
A Small Job We Are Happy to Bundle
Seals ride along perfectly with any other visit: a spring replacement, a tune-up, or roller upgrade. We carry standard widths for Tigard, King City, Sherwood, and Tualatin doors on the truck, so it is usually a same-visit add rather than a second appointment. More rain-country advice lives in our Oregon maintenance guide.
Weather Seal Questions
How much does garage door weather seal replacement cost?
A bottom seal replacement typically runs $80 to $150 in the Portland market, and a full perimeter refresh with side and top weatherstrip usually lands between $130 and $200. It is one of the smallest tickets in the trade and one of the most noticeable improvements in a rainy climate.
How do I know my garage door seal is done?
Look for daylight under the closed door, a wet stripe on the slab after rain, drafts you can feel at the floor, cracked or flattened rubber, and rodent chew marks at the corners. A healthy seal compresses against the floor evenly across the full width of the door.
Will a new seal stop rain from getting into my garage?
If water is blowing under the door, yes, a new bottom seal or a raised threshold usually ends it. If water is flowing downhill into the garage on a sloped driveway, the seal needs help from a threshold ramp or drainage. We tell you which situation you have before you spend anything.
Do new seals help keep mice out of the garage?
Meaningfully, yes. A mouse needs about a quarter-inch gap, and worn corner seals offer exactly that. Fresh bottom and side seals close the easy routes. For garages backing to greenways and creek corridors around Tigard and Sherwood, we also add rodent-resistant corner guards on request.
How long does a garage door seal last in Oregon?
Expect 5 to 10 years from quality rubber here. Our wet winters and warm summers cycle the material between swollen and baked, and south or west facing doors age faster. An annual look at the seal is part of our maintenance tune-up for exactly that reason.
