In our years serving Lakewood, we've seen this problem again and again: homeowners ignore a small draft around their garage door, only to watch their utility bills climb month after month. Weather stripping and seals wear out silently, and by the time you notice the gap, you're already hemorrhaging energy. The good news? Replacing worn seals is one of the cheapest, fastest fixes you can make, often costing under $200 and taking less than an hour.
Lakewood's coastal climate isn't kind to rubber and foam. Salt air, temperature swings, and UV exposure degrade seals faster than inland homes experience. Most weather stripping lasts 5 to 7 years before it hardens, cracks, or peels away from the frame.
The bottom seal takes the most abuse. It drags along the concrete every time your door opens and closes, compressing under the weight of the panel. Over time, that rubber loses its flexibility and stops creating a tight seal against the threshold. When that happens, cold air, dust, and moisture slip underneath.
Look for these red flags during your next walk through the garage:
Light visible under the door edges or along the bottom. Even a sliver means air (and your conditioned air) is escaping. Feel for a draft with your hand on a cool day. Wet spots or rust stains on the floor near the door. Visible cracks, gaps, or peeling rubber. A musty smell in your garage, which suggests moisture infiltration.
If you spot any of these, the cost to replace seals is far less than paying higher heating and cooling bills all year. We recommend scheduling a garage door maintenance inspection to catch seal wear before it spreads to other components.

Pricing depends on which seals you're replacing and the door's condition. Here's what Lakewood homeowners typically spend:
Bottom seal replacement: $80 to $150. This is the most common job and the quickest fix.
Side and top seals: $40 to $100 each, depending on material quality.
Full seal kit (all four sides): $200 to $350 installed.
Labor usually runs $50 to $100 per seal, though many contractors bundle the work. The threshold itself rarely needs replacement unless it's cracked or severely damaged (add $150 to $300 if it does). Request a free estimate before committing, so you know the exact cost for your door and local conditions.
Compare this to what poor seals cost you monthly. A single quarter-inch gap around your door can waste 10 to 15 percent of your garage's heating or cooling. Over a year, that translates to hundreds of dollars in wasted energy.
Handy homeowners can replace bottom seals themselves if you're comfortable removing fasteners and applying new rubber. Kits run $30 to $60 online. The catch: improper installation leaves gaps, which defeats the purpose. Uneven tension or misaligned seals reduce their effectiveness significantly.
Professional installation ensures the seal sits flush against the frame and threshold, with no air gaps. Garage Door Lakewood can handle this work fast, often same-day when you call early. The small labor cost buys you peace of mind and guaranteed performance.
If your current door is uninsulated or has failing seals, you might wonder whether upgrading makes sense. Insulated doors do retain temperature better, but new seals on your existing door will solve most draft problems at a fraction of the cost. Save the door replacement for when panels actually crack or the mechanism fails. Read our guide on insulated garage door benefits if you're curious about a full upgrade down the road.
Once new seals are installed, keep them working longer. Clean the frame and threshold monthly to prevent dirt buildup, which can compromise the seal. Avoid using harsh cleaners that degrade rubber. Check seals visually every spring to catch wear early. In Lakewood, the salt air means your seals need extra attention compared to inland areas.
Don't wait until next winter to address a failing bottom seal or draft. Small leaks snowball into big energy bills and potential moisture damage inside your garage.

Your garage door seals work 24/7 to keep the elements out. When they fail, so does your home's comfort and efficiency. The fix is simple, affordable, and worth doing now rather than later.
How long do garage door seals last in Lakewood? Most weather stripping lasts 5 to 7 years. Lakewood's coastal salt air and temperature changes can shorten that to 4 to 6 years. Regular cleaning and inspection help you catch wear before drafts develop.
Can I replace weather stripping myself? Yes, if you're comfortable removing old fasteners and aligning new rubber. DIY kits cost $30 to $60. Professional installation ensures a flush fit with no gaps and usually completes in under an hour.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber gasket attached to the door's bottom panel. The threshold is the horizontal frame piece on the concrete floor. Both work together; a worn seal or damaged threshold breaks the weathertight barrier.
Does replacing seals reduce energy bills? Absolutely. Sealing gaps around your door can reduce heating and cooling waste by 10 to 15 percent. Over a year, that saves $200 to $400 for many Lakewood homeowners, depending on energy costs and climate control use.
Should I replace seals or buy a new door? Replace seals first. New weather stripping solves 90 percent of draft problems at under $200. Only consider a new door if panels are cracked, the mechanism is failing, or you want better insulation for long-term savings.
