If you've noticed cold air creeping into your garage during winter or warm air slipping out in summer, your weather stripping and seals are likely failing. A worn bottom seal or damaged threshold lets your heating and cooling escape, raising your energy bills unnecessarily. The good news: this is one of the most affordable fixes a homeowner can make, and catching it early saves hundreds in wasted energy costs.
Our mountain location means temperature swings and moisture exposure that accelerate seal degradation. Rubber and vinyl stripping materials become brittle in cold weather and crack under UV exposure when temperatures warm up. Most weather seals last 5 to 7 years before needing replacement.
The bottom seal takes the hardest hit. It contacts your concrete floor, absorbs moisture, and flexes every time the door opens and closes. Over time, it hardens, shrinks, or tears, creating gaps where conditioned air leaks out. Even small gaps add up fast. A quarter-inch draft under your door can waste as much energy as leaving a window cracked open all winter.
Look for these red flags around your garage door. Visible cracks, peeling rubber, or daylight showing under the door edges mean replacement time. Feel along the bottom seal with your hand. It should be firm but slightly flexible, not hard or mushy.
Cold spots on your garage floor suggest the threshold is compromised. If you see water pooling inside after rain, the seal isn't doing its job. You might also notice your garage staying colder or warmer than it should, even with the door closed.
The simplest test: close the door and try to slide a credit card along the frame seals. If it glides through easily, you have a draft. Tight resistance means your seals are still effective.

A bottom seal replacement kit costs $30 to $80 at most hardware stores. If you're handy, you can tackle it yourself in an hour. Remove the old seal, clean the track, and slide the new one in place. It's straightforward.
However, if your threshold is damaged or warped, you'll need professional help. A bent threshold won't accept a new seal properly, and forcing one leads to poor performance. Professional threshold and seal replacement typically runs $150 to $300 depending on door size and damage extent.

Energy savings are real. A properly sealed garage door reduces drafts by 90 percent, which lowers your monthly heating and cooling costs by 10 to 15 percent if your garage is attached to your home. That translates to $100 to $300 per year for most households.
Beyond energy, quality seals protect your garage interior. They keep pests out, prevent water intrusion, and protect stored items from weather damage. Your car also stays cleaner and warmer when your garage is properly sealed.
Seals also protect your door's mechanical parts. Moisture that sneaks past worn seals can rust springs, cables, and hardware. Replacing a seal now costs far less than replacing corroded springs later.
Seals come in different profiles and materials. Bulb seals expand slightly when compressed, providing a tighter fit. Kerf seals fit into grooves on your door frame. Your door's design determines which type you need.

How long do garage door seals typically last? Most rubber and vinyl weather seals last 5 to 7 years in Government Camp's climate. Mountain temperature swings and UV exposure accelerate wear. Inspect annually and replace when you notice cracks, hardening, or visible gaps along the frame or bottom of the door.
Can I replace weather stripping myself? Yes, if you're replacing just the bottom seal. It's a straightforward DIY task taking about an hour. However, if your threshold is damaged or warped, professional help is needed. Improper installation leads to drafts and water leaks that cost more to fix later.
How much does weather stripping replacement cost? DIY kits run $30 to $80. Professional replacement of both seals and threshold ranges from $150 to $300, depending on door size and damage extent. Call us for an accurate estimate specific to your door.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber or vinyl strip attached to the door itself. The threshold is the metal or rubber piece on the floor where the door closes. Both must work together to prevent drafts and water intrusion.
Will new seals really lower my energy bills? Yes. Properly sealed garage doors reduce drafts by up to 90 percent, lowering heating and cooling costs by 10 to 15 percent for attached garages. Most homeowners save $100 to $300 annually, paying for the upgrade within one or two years.
