Weather Stripping & Seals in South Gate: Stop Wasting Energy
2026-05-20 7 min read
Your garage door is letting cold air in during winter and hot air in during summer. A worn bottom seal or cracked threshold can cost you $20 to $40 extra per month in heating and cooling. Weather stripping and seals in South Gate stop that draft before it starts, and the fix is simpler than you think.
Why Your Garage Door Loses Energy
Most homeowners don't realize their garage door is one of the largest moving openings in their home. When the bottom seal deteriorates, you're essentially leaving a door open to the outdoors. That gap lets conditioned air escape and outside air push in.
The culprit is usually age. Rubber and vinyl seals degrade from sun exposure, temperature swings, and repeated opening and closing. In South Gate's warm climate, UV rays accelerate this breakdown. A seal that should last 5 to 7 years might fail in 3 to 4 if exposed to intense afternoon sun.
Your energy bill reflects this loss. An unsealed garage door can increase cooling costs by 15 to 25 percent, depending on how much time you spend in or near the garage. If you park there, work there, or have a laundry room nearby, that draft hits your wallet hard.
What Exactly Are Weather Stripping and Seals?
Weather stripping refers to the rubber or vinyl material that runs along the sides and top of your garage door. The bottom seal (also called the threshold seal) is the critical piece at the base. Together, they create an airtight seal when the door closes.
A worn bottom seal leaves visible daylight between the door and the floor. You might see it yourself or notice increased noise and dust in your garage. Both are signs the seal no longer grips properly.
Replacing these components costs far less than replacing the entire door. A new bottom seal or full weather stripping package typically runs $150 to $400, depending on your door's size and material. Compare that to a $1,500 to $5,000 door replacement, and the value is obvious.

How to Spot Damaged Weather Stripping
Walk around your closed garage door in daylight. Can you see light coming through the edges? That's a red flag. Press your hand near the bottom seal on the outside. If you feel a breeze, the threshold has failed.
Listen during windy days. A whistling sound near the door usually means air is finding a gap. Dust accumulation inside the garage, especially near the door, also signals a weak seal.
If you've noticed your garage feeling unusually hot or cold compared to the rest of your home, damaged seals are a likely cause. Read our garage door maintenance guide to learn how regular inspections catch these issues early.
The Right Repair Approach
Don't patch a worn bottom seal with caulk or weatherstripping tape. Those are temporary band-aids that fail within weeks. A proper replacement involves removing the old seal and installing a new one designed for your door's profile.
The job takes 30 minutes to an hour for a standard single-car door. Double-car doors take slightly longer. The labor is straightforward, but using the right seal material matters. We use seals rated for South Gate's temperature range and UV exposure.
If your door also has damaged panels or operational issues, address those too. A door that doesn't close fully negates even the best sealing work. Schedule a free quote and we'll inspect the entire system, not just the seal.
