Weather Stripping & Seals in Clackamas: Why Your Garage Door Leaks (And How to Fix It)
2026-07-05 7 min read A2Z Garage Doors
Here's what most homeowners don't realize about weather stripping and seals: they're not just comfort features. A failing bottom seal or deteriorated threshold gasket lets water, pests, and cold air into your garage every single time you open the door. I've seen water damage escalate from a small puddle into structural rot in basements directly below the garage because the homeowner thought "it's just a draft."
Weather stripping and seals are your first line of defense against the Pacific Northwest's wet climate. In Clackamas, where rain runs nearly half the year, a compromised seal becomes a liability. Let's break down what's happening at your garage door right now and what you can actually do about it. See our guide on 5 warning signs your garage door springs need replacement.
What Weather Stripping Does (And Why It Fails)
The weather stripping and seals on your garage door create an airtight barrier. The bottom seal absorbs the impact of repeated closings. Side seals compress against the frame. The threshold gasket sits where the door meets the ground. Over time, these rubber and vinyl components harden, crack, and lose their grip.
In Clackamas' damp environment, UV exposure and temperature swings accelerate this breakdown. Most weather stripping lasts 5 to 7 years before requiring replacement. If yours is original to the door, it's almost certainly due. Read about essential garage door safety tips every family should know.
Signs your seals have failed include visible light under the door, drafts you can feel, water pooling inside after rain, or pest entry. Don't ignore these warnings. A single season of water intrusion can cause mold growth and foundation settling that costs thousands to repair.
The Real Cost of Ignoring Worn Seals
Water damage isn't the only consequence. Every gap in your weather stripping forces your heating and cooling system to work harder. If your garage is attached to your home, that draft pulls conditioned air directly outside. During Oregon winters, this adds up fast.
I've documented cases where homeowners replaced worn stripping and saw a 10 to 15 percent drop in their heating bills. For a $200 seal replacement, that's a payback period of 18 months. Beyond cost, there's the safety angle. Pests use gaps in the threshold to enter your garage and, sometimes, your home. Rodents especially exploit even quarter-inch openings.

How to Inspect Your Weather Stripping Right Now
Get a flashlight. Close your garage door completely and look for daylight around all edges. Check the bottom seal by running your hand along it from outside. The rubber should feel flexible and slightly compressed. If it cracks, peels, or feels hard as plastic, replacement is overdue.
Check the side seals where the door frame meets the jamb. They should make firm contact without visible gaps. Look at the threshold gasket directly under the door at ground level. Water stains, cracks, or separation from the concrete are red flags.

Replacement Costs and What to Expect

Threshold work costs $100 to $250. These are among the most affordable garage door repairs available, yet many homeowners delay because they underestimate the damage.
When you schedule a free quote with us, our team inspects not just the seals but the frame, weatherproofing, and door alignment.

DIY vs. Professional Replacement
You can replace some weather stripping yourself if you're handy. Adhesive-backed foam tape is straightforward. Bottom seals require removing the door from its track, which demands proper equipment and safety knowledge. Threshold replacement often involves removing the door entirely.
Mistakes here are costly. Improper installation creates new gaps, wasting money and time. A professional handles it in 30 to 60 minutes with correct alignment and sealing. Garage Door Clackamas has the tools and experience to get it right the first time.
Why This Matters in the Pacific Northwest
Clackamas gets over 40 inches of annual rainfall. That's not a gentle mist; it's sustained moisture exposure. Your weather stripping battles this constantly. In areas like Lake Oswego and West Linn nearby, the same problem appears even more severely due to elevation and drainage patterns. If you've noticed rust on your door's bottom edge or mold on the interior walls near the garage, your seals are failing now.
Don't wait for spring when contractors are booked solid. Address this during late summer or early fall so you're protected through the wet season.
Your garage door's weather stripping and seals deserve the same attention you'd give a roof leak. The difference is that seal failure happens quietly and out of sight until water damage speaks for itself. Call (541) 725-6260 or get a same-day estimate online to schedule an inspection.

Frequently Asked Questions
How often should I replace garage door weather stripping? Most weather stripping lasts 5 to 7 years depending on climate and door use frequency. Clackamas' wet environment accelerates wear. Inspect annually; replace when you see cracks, hardening, or visible light gaps around the door perimeter.
Can I replace weather stripping myself? Adhesive foam tape is DIY-friendly. Bottom seal and threshold replacement requires door removal and precise alignment. Professional installation ensures proper compression and sealing. Most homeowners benefit from hiring a technician to avoid costly misalignment.
What's the difference between weather stripping and a bottom seal? Weather stripping refers to the side and top seals that compress against the frame. The bottom seal is a specialized component that sits at the door's base and absorbs impact. Both are essential for a complete weather barrier.
Will new seals stop drafts completely? New seals eliminate 90 to 95 percent of draft and water infiltration if the door is properly aligned and tracks are clean. If your door binds or doesn't close flush, alignment adjustment may be needed alongside seal replacement.
