Steel, Aluminium, Wood or Composite: Which Door Suits Florida?

Each material behaves differently in heat, humidity and salt. Here is how they actually hold up here.

9 December 2026 6 min read By the BH Garage Door team

Material choice is usually made on looks and price. In Florida it is worth thinking about climate first, because that is what decides how the door looks in ten years.

How each holds up here
MaterialIn FloridaBest suited to
Insulated steelHandles heat and humidity well; watch cut edges near saltMost homes — the default for good reason
AluminiumWill not rust, which is a real advantage on the coastBeachfront, modern full-view designs
Composite / faux woodWood look, no swelling or rotCharacter homes without the upkeep
Real woodHard work here — sun and humidity both attack itOnly with committed maintenance

We fit a lot of insulated steel and very little real wood. Wood doors look wonderful for about three years here and then need serious attention.

The coastal exception

Within sight of salt water, aluminium becomes genuinely attractive. It costs more and dents more easily, but it does not rust, and rust is what finishes steel doors near the beach.

Do not judge steel by gauge alone

A lower gauge number means thicker steel. But construction matters more — a two or three layer door with a polyurethane core is stiffer and quieter than a thicker single skin.

Whatever you choose

  • Confirm the wind-load rating for your address.
  • Check what the finish warranty covers, and for how long, in coastal conditions.
  • Ask about the hardware — galvanised or coated makes a real difference near salt.
  • Match the Garage Door Opener to the finished door weight.

What actually matters when you are choosing

A garage door is often a third of everything you see from the street. It is also the largest opening in the building.

So what does that mean day to day? So it is two purchases at once: a design decision and a structural one.

In Florida the structural half is not optional. The wind-load rating has to match your address, and in Miami-Dade and Broward the requirements are stricter again. We say that from experience, not from a brochure.

Where the money actually goes

Two quotes for what looks like the same job can differ a lot, and the difference is rarely the labour.

Let us be honest about this bit. It is usually part quality. A ten-thousand-cycle spring and a thirty-thousand-cycle spring take the same time to fit and last very differently.

It is also construction. A two or three layer door with a polyurethane core is stiffer, quieter and holds its rating better than a thicker single skin.

Ask what is going on the door, not just what it costs. That single question makes quotes comparable. We say that from experience, not from a brochure.

What we go through before quoting

Opening width, height, headroom and side room — these decide what track is even possible.

That is the theory. Here is the reality. The wind-load requirement at your specific address, not a state average.

Whether the garage is attached, and what sits above or beside it, which drives insulation.

Whether your existing opener is rated for the weight of the door you are choosing.

The spring specification for the finished door weight. It is a small thing that turns into a big thing.

The mistake we see most

Picking the door on looks, then finding the approval does not exist for that address.

One more thing, because it matters. It is a genuinely miserable conversation to have after someone has set their heart on a design.

Have the code conversation and the design conversation at the same time. It costs nothing up front and it stops the whole project stalling. Nobody enjoys hearing it, but it saves money.

The short version

If you take one thing away from all of that: a door that is balanced, lubricated and has working safety reverses will outlast one that is not. By years, not months.

Almost everything we get called out to was preventable. Most of it was cheap to prevent, too.

So if any of this sounds like your door, get eyes on it while it is still an inconvenience rather than a breakdown. We would rather do the small job.

FAQ

Questions about Buying Guide

Get quick answers to common questions about our garage door repair, installation, and maintenance services.

How quickly can someone get out to me?

We cover Florida every day and most jobs are same-day. Emergencies — a door stuck open, a snapped spring, a door off its track — jump ahead of routine work.

Do you work on every brand?

Every major door and opener brand. The hardware varies far less than the badges suggest.

What if it turns out to be something else entirely?

Then we tell you. We would rather do the smaller job honestly than sell you the bigger one.

Do you carry parts on the van?

Common springs, cables, rollers, hinges and brackets, yes. That is why most visits finish on the first call instead of turning into a return trip.

Is it worth repairing an older door?

Usually. The moving parts are consumables and the door itself is the asset. We only push replacement when the structure has gone or the door cannot meet the wind rating for your address.
