Replacing a garage door is one of those home projects that most people only do once or twice in a lifetime. You want to get it right. especially here on Merritt Island, where the climate, the building codes, and the coastal environment all factor into which door is actually going to perform well over the long haul.
This guide gives you the real picture: what doors cost in Florida, which materials make sense for our conditions, how the permitting process works in Brevard County, and what questions to ask before you commit to anything.
Located between the Indian River and the Banana River, Merritt Island is surrounded by water on both sides. That means persistent humidity, salt-laden air, and a direct exposure to Atlantic storm tracks that inland cities like Melbourne or Palm Bay simply don't face in the same way.
The housing stock here ranges from 1960s and 70s-era ranch homes and coastal cottages. many in neighborhoods like Surfside Estates and Diana Shores. to newer Mediterranean-style builds near The Savannahs golf community and luxury riverfront estates along South Tropical Trail. Older homes often have undersized single-car openings. Newer builds more commonly have two-car or split double-car configurations. The right door choice depends heavily on your specific opening size, home style, and how much weather exposure your garage faces.
Let's be direct about pricing. In Florida, a standard single-car garage door with installation typically runs $1,000,$2,200. Double-car doors range from $1,800,$3,500 or more, depending on materials, insulation, and wind-load ratings. These are installed prices. not just the door off a shelf.
Here's what moves the number up or down:
- Material: Steel is the most common and most affordable. Aluminum is lightweight and naturally rust-resistant, making it a strong choice for coastal climates. Wood looks beautiful but requires real maintenance commitment in our humidity. expect warping and paint issues within a few years without consistent upkeep. - Insulation: An insulated door costs more upfront but keeps your garage cooler in summer (Merritt Island summers routinely push into the high 80s and 90s) and reduces road noise. If your garage is attached or you use it as a workspace, the upgrade is usually worth it. - Wind-load rating: This is where Florida gets specific. Most counties require wind-rated doors for new installations, and in coastal Brevard County, that requirement is taken seriously. Wind-rated doors typically add $300,$800 to the cost but are non-negotiable for code compliance. and they may reduce your homeowner's insurance premium. - Style and hardware: Carriage-style doors with decorative hardware are popular in newer Merritt Island neighborhoods and typically run $1,800,$4,000 for a double-car configuration.
For a two-car garage, budget at least $2,000,$3,500 all-in for a quality, code-compliant installation. That's a realistic range for what most homeowners on this island are spending.
This is where a lot of homeowners make expensive mistakes. Here's an honest breakdown:
Best for: Most homeowners. Durable, widely available, and affordable. Galvanized or zinc-coated steel panels hold up reasonably well near salt air, especially with periodic washing and touch-up painting. Triple-layer insulated steel offers excellent thermal performance.
Best for: High-humidity coastal environments. Aluminum is naturally corrosion-resistant, which is a meaningful advantage on Merritt Island. It's lighter than steel, so it's easier on springs and openers. The tradeoff is that it dents more easily and costs a bit more than basic steel.
Best for: Homeowners who are committed to maintenance. Real wood looks stunning on a South Tropical Trail estate, but in our subtropical climate with summer humidity regularly above 70%, wood doors require annual sealing, painting, and inspection. A neglected wood door will warp and rot within a few years.
Best for: Homeowners who want a wood look without the maintenance headache. Fiberglass handles salt air better than most materials and won't rot, though it can become brittle over time in intense UV exposure.
Yes, you typically need a permit to replace a garage door in Florida, particularly when the new door involves a different wind-load rating or structural changes to the opening. Permit costs generally range from $50,$200, and inspections are required to confirm code compliance.
A reputable installer will pull the permit for you as part of the job. If a company offers to skip the permit to save time or money, walk away. it creates problems when you sell the home and voids your warranty protection.
Also check your HOA if applicable. Neighborhoods like The Savannahs and Villa De Palmas have architectural review processes, and certain door styles or colors may require pre-approval. Check our FAQ page for more details on what the installation process typically involves.
Before committing to a new door installation, ask these questions:
1. Is the door wind-load rated for Brevard County? Get the specific rating in writing. 2. Will you pull the permit? The answer should be yes. 3. What's included in the installation price? Confirm whether removal of the old door, new hardware (tracks, rollers, springs), and opener compatibility are included or priced separately. 4. What's the warranty on parts and labor? A quality door typically carries a manufacturer warranty of 1,5 years on hardware; ask what labor warranty the installer stands behind. 5. Is my existing opener compatible? Heavier doors sometimes require a more powerful opener motor. If your opener is older, now may be the time to address it.

A new door and an old opener is a common mismatch. If the new door is heavier or larger than what you had, an underpowered opener will strain from day one. If you're already replacing the door, evaluate the opener at the same time. Modern belt-drive and DC-powered openers are significantly quieter than the chain-drive units common in older Merritt Island homes, and many now include battery backup. important when afternoon thunderstorms knock out power across Brevard County.

Brevard County requires wind-load rated doors for new garage door installations, and as a coastal community with direct exposure to Atlantic storm systems, Merritt Island homeowners should not skip this requirement. A wind-rated door adds cost upfront but is essential for code compliance, insurance purposes, and actual storm protection. See our storm preparation guide for more on protecting your home during hurricane season.
Most residential installations take 3,5 hours for a single door and 4,7 hours for a double. This includes removing the old door, installing new tracks and hardware, mounting the door panels, and testing the opener system. More complex installations. custom sizing, structural modifications, or new opener wiring. take longer.
Aluminum and properly treated steel (galvanized or zinc-coated) both perform well in Merritt Island's salt air environment. Aluminum has a natural edge on corrosion resistance and is lighter on your spring system. Fiberglass is another solid option if you want a wood aesthetic. Whatever material you choose, rinse the door exterior with fresh water every 2,3 months to remove salt buildup. it makes a real difference in long-term performance.
