Serving Molalla, we see this problem again and again: homeowners lose hundreds in heating costs every winter because their garage door weather stripping and seals have deteriorated. A worn bottom seal or threshold lets cold air pour into your garage, which then seeps into your home. The good news? Fixing it costs far less than paying higher energy bills all season long, and most repairs happen the same day you call.
Your garage door's weather stripping creates an airtight barrier. The bottom seal (also called a threshold gasket) sits at the garage floor. Side seals run vertically. Top seals cap the frame. Together, they block drafts, keep moisture and pests out, and maintain your home's temperature.
When seals fail, warm air escapes in winter and cool air bleeds out in summer. Your HVAC system works overtime. Over a heating season in the Molalla area, that draft costs real money.
Look for these red flags around your garage door:
Visible gaps between the door and frame. Daylight peeking through at the bottom, sides, or top. Cold air flowing into your garage on winter mornings. Water pooling inside after rain. Pest droppings or insect activity near the door threshold. Cracked, hardened, or missing rubber material.
If you notice any of these, your weather stripping and seals have likely reached the end of their useful life. Most seals last 5 to 7 years depending on sun exposure and climate. The Willamette Valley's wet winters accelerate wear, so Molalla homes often need replacement sooner than expected.
Weather stripping and seal replacement cost significantly less than spring repair or door replacement. A typical bottom seal runs $80 to $200 installed. Side seals add $60 to $150 each. Full weatherization (all seals plus any threshold repair) typically ranges from $200 to $400 for most Molalla homes.
That estimate depends on your door type, frame condition, and whether the threshold itself needs rebuilding. Check our guide on garage door cost and pricing in Molalla to understand what drives your specific quote.

Some homeowners try replacing seals themselves. It's tempting because kits cost $30 to $80. But here's the catch: improper installation leaves gaps. A seal installed crooked or at the wrong tension won't seal properly, defeating the entire purpose. Poor installation also voids manufacturer warranties on the seal material itself.
Professional installation ensures correct fit, proper compression, and longevity. You pay more upfront but avoid costly redo work and energy waste. For most Molalla homeowners, the labor cost is money well spent.
Fall is the ideal time to address weather stripping and seals. Before winter arrives, you want your garage door fully sealed. A summer inspection catches wear early, so repairs happen before the heating season kicks in.
If your seals are already failing in November or December, don't wait. Winter drafts compound the problem, and scheduling delays waste more heating dollars. Our maintenance schedule guide explains the best times to address different garage door issues.
Worn seals often appear alongside other issues. If your door is hard to open, the track may be dry or springs may be weakening. Springs typically need replacement after 7 to 9 years, which is often the same timeframe as seal wear.
A full maintenance tune-up catches all three problems at once, saving you money on separate service calls. When you contact Garage Door Molalla for a seal inspection, ask about lubrication and spring tension while we're there.

How long do weather stripping and seals last? Most seals last 5 to 7 years. Oregon's wet climate and temperature swings accelerate breakdown. Sun exposure, door frequency, and material quality also affect lifespan. Regular inspection helps catch wear early before energy loss becomes severe.
Can I replace seals myself? It's possible but risky. Improper installation leaves gaps, voids warranties, and wastes money. Professional installation guarantees correct fit, proper compression, and reliable sealing. The labor cost typically pays back within one heating season through energy savings.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber gasket attached to the door itself. The threshold is the channel or frame piece at the garage floor where the seal sits. If the threshold is damaged, cracked, or warped, it must be repaired or replaced for the seal to work properly.
Will new seals help with pest control? Yes. Gaps around your door invite rodents, spiders, and insects. A tight seal blocks their entry points. Combined with caulking any remaining cracks in the frame, new seals eliminate most pest access through your garage door.
How do I know if my seals are failing? Look for daylight at the bottom or sides of the door. Feel for cold drafts inside your garage. Check for water stains or pooling after rain. Visible cracks, hardness, or missing chunks of rubber are also clear signs. An inspection catches early wear before it becomes expensive.
