If you've noticed air leaking around your garage door, higher electric bills, or rust creeping in from outside, your weather stripping and seals are probably failing. In Fort Myers Beach, our salt air and humidity break down rubber and foam seals faster than most places. The good news: replacing them is affordable, stops drafts cold, and takes just a few hours. We'll walk you through what's happening, what it costs, and why acting now beats waiting until bigger damage shows up.
Living steps from the ocean means your garage door faces constant assault. Salt air corrodes metal. Humidity swells and shrinks rubber. UV sun bleaches foam. Over 3 to 5 years, the bottom seal and threshold that keep out wind, rain, and pests turn brittle and crack.
When seals fail, you're not just dealing with a draft. Water gets in. Insects find a highway. Your air conditioning works twice as hard. If you park a car inside or store tools, rust becomes your new problem. The threshold (that rubber piece at the base) takes the worst beating because it sits on concrete and gets walked on constantly.
The salt air situation is real. If you've ever noticed how quickly metal rusts near the beach, imagine what it does to your garage door hardware and the metal edges of seals over months and years.
Your garage door has four seal locations: top, sides, bottom, and threshold. Each one stops something different.
The bottom seal and threshold catch rainwater and block bugs from crawling underneath. Side seals stop sideways wind and drafts. The top seal keeps heat and cool air from escaping upward. When even one fails, your garage becomes a semi-open space to the weather.
Here's the real impact: a failed bottom seal can let 15 to 20 percent more air escape. That drives up cooling costs fast in our Florida climate. It also invites moisture that rusts door springs and openers. We've replaced springs that corroded early partly because water kept dripping past a dead seal.
Weather stripping and seal replacement in Fort Myers Beach typically runs $150 to $400 depending on which seals need work and your door size. A bottom seal alone costs $80 to $150 in labor and materials. A full seal kit, all four sides, runs $250 to $400. We always give a free estimate before we start, so no surprises.

Most jobs finish same-day. We come out, inspect all four seal locations, tell you exactly what's worn, quote the cost, and get it done while you wait. No markup, no upsell. If a seal has another year left in it, we'll tell you that too.
If you haven't yet, read our post on how salt air destroys your garage door. Seals are your first line of defense. When they fail, water reaches springs, cables, and the opener motor. A $300 seal replacement stops a $1,200 spring replacement down the road.
The same logic applies to hurricane season. Strong winds exploit gaps where seals have pulled away from the frame. If you're thinking about hurricane proofing your garage door, new seals are part of that package.
You can replace some seals yourself if you're handy. Bottom seals usually slide into a channel. Side seals glue on. Threshold pieces bolt down.
The catch: if you buy the wrong size or install it crooked, you're back where you started. Misaligned seals don't seal. They just look like they do. Also, removing old caulk and adhesive takes longer than most homeowners expect. If you're unsure, schedule a free quote and let us handle it right the first time.
If a seal is cracking but still mostly intact, you might caulk it for another season. If it's peeling, missing chunks, or hardened like plastic, replacement is the only fix that lasts. Same with the threshold. Once it's cracked across the width, caulk won't hold.
We recommend a full inspection every two years in Fort Myers Beach. Salt air accelerates wear. Better to catch a seal at 80 percent worn than let it fail completely and invite water damage.

Weather stripping and seals are small parts that do huge work. When they fail, drafts, water, and pests follow. In Fort Myers Beach, our climate makes them wear out faster. But replacement is fast, affordable, and prevents bigger repairs.

How long do garage door seals last? In Fort Myers Beach, weather stripping typically lasts 3 to 5 years. Salt air and UV exposure accelerate breakdown. Northern climates see 5 to 7 years because freeze-thaw cycles are gentler on rubber than constant salt exposure.
Can I replace just the bottom seal? Yes. The bottom seal is the most common failure point because it takes the most foot traffic and weather exposure. You can replace it alone without touching the sides or top. Cost usually runs $80 to $150 in materials and labor.
Do new seals really save energy? Absolutely. A failed bottom seal and threshold let 15 to 20 percent more conditioned air escape. In Florida's heat, that adds up fast. Many customers see lower AC bills within a month of seal replacement.
What's the difference between a bottom seal and a threshold? The bottom seal is a rubber or foam strip that attaches to the door itself. The threshold is a metal or rubber channel that sits on the concrete floor under the door opening. Both work together to block air, water, and pests.
How long does weather stripping replacement take? Most jobs finish in 1 to 2 hours. If we're replacing all four seal locations, plan for the longer end. Side and top seals glue on and need time to set, so we often come back a few hours later to test the door.
