Jacksonville Homeowners: Protect Your Garage Door From Salt-Air Corrosion
Florida’s coastal beauty comes with a hidden enemy—relentless humidity and salt air that accelerates garage door rust. If you’ve noticed orange-brown spots, peeling paint, or weakened metal, your garage door could be deteriorating faster than you think.
This guide covers garage door rust repair in Jacksonville, whether aluminum or steel doors hold up better, and the best protective coatings to prevent future damage. Plus, discover when it’s time to call Palm Valley Garage Doors for professional help.
Why Florida’s Climate is a Garage Door’s Worst Enemy
Jacksonville’s salt-laden ocean air, high humidity, and frequent storms create the perfect storm for rust and corrosion. According to the Florida Department of Environmental Protection, coastal areas experience 3x faster metal corrosion than inland regions.
How Rust Forms on Garage Doors:
✔ Salt Air – Speeds up oxidation, especially on steel doors.
✔ Humidity – Traps moisture against metal surfaces.
✔ Storm Exposure – Rain and wind drive salt deeper into door panels.
Left untreated, rust weakens structural integrity, jams rollers, and ruins curb appeal.
Aluminum vs. Steel Garage Doors: Which Holds Up Best in Florida?
1. Steel Garage Doors (Most Common but Rust-Prone)
✅ Pros: Affordable, strong, and customizable.
❌ Cons: Requires regular maintenance to prevent rust.
Best for: Inland homes (less salt exposure) with protective coatings.
2. Aluminum Garage Doors (Rust-Resistant but Less Durable)
✅ Pros: Naturally corrosion-resistant, lightweight.
❌ Cons: Dents more easily, less insulation.
Best for: Coastal homes in Jacksonville Beach, Ponte Vedra, or Palm Valley.
How to Repair Garage Door Rust in Jacksonville (DIY Steps)
1. Assess the Damage
🔍 Surface Rust (Early Stage): Light discoloration, no flaking.
🔍 Moderate Rust: Paint peeling, small pits in metal.
🔍 Severe Rust: Holes or weakened panels—may need replacement.
2. Remove Rust (Step-by-Step)
A. Light Surface Rust
- Tools Needed: Wire brush, sandpaper (80-120 grit), rust converter.
- Steps:
- Scrub off loose rust with a wire brush.
- Sand smooth.
- Apply rust converter gel to stop spread.
B. Moderate to Heavy Rust
- Tools Needed: Angle grinder (with flap disc), epoxy filler, primer.
- Steps:
- Grind away rust until bare metal is exposed.
- Fill pits with metal epoxy filler.
- Sand smooth and prime.
3. Apply Protective Coatings
After rust removal, seal the metal to prevent future damage:
✔ Rust-Oleum Garage Door Paint – Extra moisture resistance.
✔ Marine-Grade Clear Coat – Best for coastal homes.
✔ Galvanized Spray – Adds a zinc layer for steel doors.
Pro Tip: Repaint every 2-3 years in coastal zones.
5 Ways to Prevent Garage Door Rust in Florida
1. Install a Protective Overhang
- A 6-inch roof overhang reduces direct rain/salt exposure.
2. Rinse Monthly with Fresh Water
- Spray down doors to remove salt buildup.
3. Lubricate Moving Parts
- Use silicone-based lubricant (not WD-40) on hinges and rollers.
4. Upgrade to Stainless Steel Hardware
- Replace rusty bolts, hinges, and springs with 316-grade stainless steel.
5. Consider a Fiberglass or Vinyl Door
