A customer called last Tuesday complaining her heating bill had jumped $40 a month. She'd noticed cold air seeping under the garage door, especially on Winlock's chilly mornings. The fix? Fresh weather stripping and a solid bottom seal. Within two hours, the draft was gone. Her energy waste stopped immediately. That's the power of proper weather stripping and seals.
Most homeowners don't realize how much heat or cool air escapes through a worn garage door. A damaged bottom seal or deteriorated weatherstripping acts like an open window. In Winlock's climate, where winters dip below freezing and summers stay mild, that gap costs real money every single month.
Weather stripping and seals serve one job: create an airtight barrier between your garage and the outside. When they fail, you lose conditioned air. Your furnace or AC runs longer. Your utility bill climbs.
Rubber and foam deteriorate over time. Temperature swings crack them. UV light hardens them. Dirt and debris compress them flat. In the Pacific Northwest, moisture accelerates that breakdown. Most seals last 3 to 5 years before they stop doing their job.
The bottom seal takes the worst beating. It sits on concrete, absorbs moisture, flexes every time you open and close the door. A cracked or missing bottom seal is like leaving your garage door open 24/7. Heat pours out. Pests creep in. Moisture invades.
Energy waste is invisible until you see it on your bill. A poorly sealed garage door can cost you $30 to $60 per month in wasted heating or cooling. Over a year, that's $360 to $720. A new weather stripping and seal kit costs between $150 and $400, installed. The payback period is less than a year.
Beyond energy, drafts allow moisture and pests into your garage. Water damage to stored items. Rodents nesting in corners. Rust forming on tools and equipment. These secondary costs multiply fast.

Not all stripping is created equal. Foam tape is cheap but wears out quickly. Rubber bulbs last longer and seal tighter. Vinyl and silicone hybrid materials resist cracking in extreme cold.
Your bottom seal matters most. Vinyl bottom seals are standard and affordable. Astragal seals (which replace the entire bottom frame component) cost more but last 7 to 10 years. Threshold seals fit under the door and add extra protection.
The right choice depends on your door's age, condition, and your budget. An honest estimate should break down which seal type solves your specific draft problem. If you're seeing condensation or feeling air movement, you need an inspection before you buy anything.

You can buy weather stripping kits at any hardware store and install them yourself. Peeling off old foam and pressing on new tape takes 30 minutes.
But bottom seals require removing the door's bottom bracket. That's where it gets tricky. If the bracket isn't perfectly aligned or the seal isn't seated right, you'll still have drafts. Worse, a misaligned seal can bind when the door opens, wearing out your opener or springs.
Professional installation ensures the seal sits flush and level. A technician adjusts the bracket if needed. You get a warranty on the work. Same-day service means no week-long wait in cold weather.
For Winlock residents, a professional weather stripping and seal service includes inspection, removal of old material, proper surface prep, and correct installation. The cost is typically $200 to $400 depending on seal type and door condition.
A real estimate tells you exactly what's failing. Is it the top weatherstripping? The side seals? The bottom threshold? Each problem has a different solution.
The technician should measure your door's dimensions, inspect all four sides, and note any alignment issues. If your door is sagging or out of square, no seal will work perfectly until that's fixed. A good estimate mentions this upfront so you understand trade-offs.
If your garage door has bigger structural issues, check our post on signs your garage door needs professional repair to see if seals alone will solve the problem.
Pricing should be transparent. Labor. Materials. Disposal of old seals. Tax. No surprise fees. Call Garage Door Winlock at (360) 637-1102 for a free estimate, or schedule a free quote online to discuss your draft problem and get an exact cost.
Winter is peak season for seal calls. Cold air is obvious. But fall is smarter timing. Repair seals before winter hits, not during the coldest week when everyone's desperate. You'll get faster service and better availability.
Spring is also good for checking seals. Winter damage shows up. Summer heat can be the first sign something's wrong if your AC bill spikes.
Don't wait until a seal fails completely. Small cracks and compression can be fixed before they become major drafts. A quick inspection costs nothing and saves money in the long run.
How long do weather stripping and seals last? Foam weatherstripping lasts 2 to 3 years. Rubber and vinyl seals last 3 to 5 years. Bottom seals may need replacement every 4 to 7 years depending on climate and use. Regular inspection helps you catch wear before drafts start.
Can I replace weatherstripping myself? Yes, basic weatherstripping tape is DIY friendly. Remove old material, clean the surface, and press new tape on. Bottom seals and thresholds are trickier because they require bracket adjustment and precise alignment to work properly.
What's the difference between weatherstripping and a bottom seal? Weatherstripping is the rubber or foam material along the top and sides of the door frame. The bottom seal (or threshold) is a separate component at the bottom that creates a barrier between the door and the concrete. Both are essential for a tight seal.
How do I know if my seals need replacing? You'll feel cold air or drafts around the door. Moisture may collect inside the garage. Your heating or cooling bills may increase. Visual inspection shows cracks, hardening, or missing pieces in the rubber or foam material.
Will new seals stop all noise and drafts? Quality seals eliminate most drafts and reduce outside noise significantly. If your door is misaligned or warped, seals alone won't fix everything. A professional inspection identifies whether the door itself needs adjustment or replacement.
