A customer called last Tuesday morning. His electric bill had jumped forty dollars a month, and he couldn't figure out why. After pulling into his driveway, I spotted the problem immediately: the bottom seal on his garage door had rotted and peeled away. Hot, humid air from outside was pouring straight into his conditioned garage. Weather stripping and seals in Intercession City fail faster than most homeowners expect, especially in our subtropical climate. The good news? This is one of the easiest fixes we handle, and it pays for itself in energy savings within weeks.
Florida's heat and humidity are brutal on rubber. The sun bakes it. The moisture swells it. Temperature swings crack it. Most garage door weather stripping lasts between 5 and 7 years here in Central Florida, not the 10 years manufacturers claim.
Your door has seals in four places: the bottom seal (the rubber piece that touches the ground), the side seals (jamb seals running vertically), the top seal, and sometimes a threshold at the floor. Each one works to block drafts, pests, and water. When any of them fail, you lose conditioning, invite bugs, and risk water damage inside your garage.
I've been installing and replacing these seals for fifteen years. The bottom seal goes first almost every time. It takes the most abuse. It flexes every time the door cycles up and down, and it sits closest to ground moisture and UV radiation.
You might think skipping a seal replacement saves money. It doesn't. Energy loss from a missing or crumbling bottom seal can add 15 to 25 dollars monthly to your cooling costs. Multiply that by twelve months, and you're looking at 180 to 300 dollars a year wasted.
Beyond energy, failed seals let in: - Moisture and mold growth, Insects and rodents, Dust that damages your car and belongings, Heat transfer that makes your HVAC work harder

Replacing weather stripping and seals is straightforward work. We remove the old seal (which usually crumbles or slides out), clean the track or frame where it sits, and install new material. The entire job takes under an hour for a standard residential door.
Cost varies depending on which seals you need. A bottom seal alone runs between 80 and 150 dollars installed. A full seal kit (all four positions) typically ranges from 200 to 350 dollars. For a detailed breakdown of garage door pricing, read our honest cost guide.
We use commercial-grade seals rated for Florida weather. Cheap rubber fails fast. I've seen homeowners buy hardware store kits and replace them twice in three years. Better to invest once in a quality threshold and seal package from someone who knows the local climate.
Look for these warning signs:
Visible cracks or peeling. If you see rubber that's torn, cracked, or separating from the frame, replacement is overdue.
Daylight showing under the door. Close your door at night and go inside the garage with lights off. Shine a flashlight along the bottom and sides. Any light leaks mean seals have failed.
Drafts or cold spots. Feel around the bottom of the closed door in winter. Cold air rushing in signals a gap.
Water pooling inside after rain. Failed bottom seals let water run straight into your garage.
Increased pest activity. Gaps that let air through also let insects through.

Regular maintenance extends seal life. Keep the door clean and dry. Avoid parking wet vehicles inside, which adds humidity. Keep debris out of the tracks. And inspect seals every six months, especially before summer and after heavy rains.
Weather stripping and seals aren't glamorous, but they're essential. Think of them like the weatherstripping around your front door. Nobody notices it until it fails. Then everything goes wrong fast.
The customer from Tuesday? He approved the seal replacement on the spot. His next bill dropped twenty-two dollars. He called back two weeks later to say he'd also noticed the garage felt less humid and he hadn't seen a single roach. Small fix. Big difference.
Don't wait for your energy bill to spike or pests to move in. Call Intercession City Garage Doors at (863) 267-9123 and get a same-day estimate. We'll inspect all four seal positions and give you an honest assessment of what needs work and what can wait.
How long do garage door weather seals last? In Intercession City's heat and humidity, most seals last 5 to 7 years. Bottom seals often fail first due to constant flexing and ground moisture exposure. Annual inspections catch wear early.
Can I replace weather stripping myself? Yes, bottom seals are DIY-friendly if you're comfortable with basic tools. Side and top seals are trickier. If you're unsure, professional installation ensures proper fit and avoids air gaps that waste energy.
What's the difference between a seal and a threshold? A threshold is the metal or rubber piece at the floor where the bottom seal attaches. The seal is the rubber component. Both may need replacement if your door has a draft problem.
Do I need to replace all seals at once? Not necessarily. If only the bottom seal has failed, replace just that one. But if multiple seals show cracks, replacing all four at once saves labor costs and ensures uniform protection.
Will new seals reduce my AC bill? Yes. A missing or failed bottom seal can cost 15 to 25 dollars monthly in cooling loss. New seals typically pay for themselves within two months during summer months.
