A damaged bottom seal on your garage door lets heat escape in winter and cool air leak out in summer, inflating your electric bill every month. Replacing it typically costs between $150 and $400 in Wellington, depending on whether you need just the seal or the entire threshold assembly. Most homeowners can avoid paying premium repair costs by catching wear early.
Your garage door's bottom seal is the rubber or vinyl strip that runs across the lowest edge of the door. It compresses against the threshold (the metal or concrete strip on the floor) to block drafts, pests, and water from entering your garage.
Over time, Wellington's heat and humidity cause rubber to crack, harden, and separate from the door. Once that seal fails, you're essentially leaving a gap open to the elements. The threshold can also warp or corrode, which prevents a new seal from sealing properly.
If you've already dealt with a stuck garage door, a failing seal may have been part of the problem. We covered that scenario in detail over at our garage door getting stuck in Wellington heat guide, which also touches on how seals interact with overall door operation.
Look for visible cracks, chunks missing from the rubber, or daylight visible under the closed door. If you feel a draft near the threshold on a calm day, the seal has likely failed. You might also notice an uptick in your cooling costs or see insects and debris in your garage.
A seal typically lasts 5 to 7 years in Florida's climate. If your door is older and you've never replaced the seal, now is the time to get an estimate.
A bottom seal alone (just the rubber strip) costs $150 to $250 installed in Wellington. If the threshold itself is bent, rusted, or damaged, you'll need the full threshold assembly replaced, which runs $300 to $400.
The good news: most seals fail before thresholds do. A quick inspection tells you which you actually need. Garage Door Wellington can assess your door and quote you the right fix, not the expensive one.

You can replace a bottom seal yourself if you're handy. The seal typically slides or screws into a channel at the base of the door. However, if the threshold is damaged or the door hangs unevenly, a professional should handle it to avoid creating new problems.
If you're unsure, schedule a free quote and let a technician decide. It often costs less than a botched DIY job.
Beyond stopping drafts, a good seal keeps your garage insulated. That matters if you use the space for storage, a workshop, or if your home office is nearby. Even if your garage door insulation is already solid, a worn seal undermines those benefits.

A single-car door seal replacement: $150 to $250. A double-car door seal replacement: $200 to $300. Full threshold replacement (either size): $300 to $400.
Labor is included in those figures. Parts alone are cheap; labor and proper installation are what you're paying for.
If the seal is cracked but still attached and the threshold looks straight, replacement is the move. If the threshold is severely warped or corroded, you need the full assembly. A technician can tell you in minutes.
Don't wait for the seal to completely disintegrate. Small cracks become big gaps fast, and that costs you money every day.
Your next step is simple: call (561) 530-2287 or request an estimate online to lock in a fair price. Most jobs wrap up the same day you book them.
How long does a garage door bottom seal last? In Wellington's heat and humidity, rubber seals typically last 5 to 7 years. Regular inspection helps you catch wear before it becomes a problem and drives up your electric bill.
Can I replace the bottom seal myself? Yes, if you're comfortable with basic tools. The seal slides or bolts into a channel at the door's base. If the threshold is damaged or the door hangs unevenly, hire a pro to avoid creating new issues.
What happens if I ignore a worn bottom seal? Your garage loses temperature control, pests and moisture enter, and your cooling and heating costs climb. A $200 repair now beats a $500+ bill later from water damage or pest infestation.
Do I need to replace the threshold if I replace the seal? Not always. If the threshold is straight and clean, a new seal alone works fine. A technician will inspect and tell you exactly what's needed, not what's profitable.
How quickly can you install a new bottom seal in Wellington? Most jobs take under an hour. Same-day service is available for many appointments. Call (561) 530-2287 to check availability.
