The 30-Second Verdict
Fiberglass doors resist Florida's humidity and salt air better long-term and can mimic wood beautifully; steel doors cost less upfront but can rust in coastal Florida environments. Both can be impact-rated.
Head-to-Head Breakdown
Fiberglass Doors
Pros
- Won't rust, rot, or warp—ideal for Florida's humidity and salt air
- Can be made to look like real wood grain
- Excellent insulation value (foam core)
- Impact-rated options available for hurricane protection
- Low maintenance—doesn't require repainting as frequently
- Won't dent as easily as steel under impact
Cons
- Higher upfront cost than steel (typically $300–$600 more per door)
- Can fade in intense Florida UV if low-quality finish
- Repairing deep scratches is more difficult than steel
Steel Doors
Pros
- Lower upfront cost ($200–$500 less than comparable fiberglass)
- Excellent security—harder to kick in than fiberglass
- Good insulation with foam fill
- Impact-rated options widely available
- Easier to paint and repaint
Cons
- Can rust in coastal Florida environments if finish is damaged
- Dents more easily under impact
- Higher thermal conductivity (transfers heat more than fiberglass)
- Requires more maintenance in salt air/coastal areas
Side-by-Side Comparison
| Fiberglass Doors | Steel Doors | |
|---|---|---|
| Starting Price (pre-installation) | $400–$1,200 for the door | $200–$900 for the door |
| Installed Cost (door + labor) | $1,200–$3,500 | $900–$2,800 |
| Maintenance in Florida | Low—occasional cleaning and resealing | Moderate—watch for rust on coastal properties |
| Rust Risk | None | Yes, particularly within 5 miles of the coast |
| Wood Appearance | Excellent (grain embossed in fiberglass) | Limited; smooth or basic textured only |
| Insulation (R-Value) | R-5 to R-10 typically | R-5 to R-7 typically |
| Impact Rating Availability | Yes, widely available | Yes, widely available |
| Best For | Coastal Florida, high-humidity areas, homeowners wanting wood look | Inland Florida, budget-conscious buyers prioritizing security |
Frequently Asked Questions
Which door type is better for hurricane protection in Florida?
Both fiberglass and steel doors can be manufactured to meet Florida's impact-resistant (hurricane) standards. Look for Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval when purchasing an impact-rated door. The door frame and proper installation are equally critical for hurricane performance.
Do I need an impact-rated door in Florida?
Florida Building Code requires impact-rated or shutter-protected openings (including entry doors) in the High Velocity Hurricane Zone (Miami-Dade and Broward counties) and in wind-borne debris regions. Even outside these mandatory zones, impact-rated entry doors qualify for homeowners insurance wind mitigation discounts.
Which brand of entry doors is best for Florida?
Well-regarded brands for Florida include Therma-Tru (fiberglass), ProVia (fiberglass and steel), Masonite (both), and PGT for impact-rated products. Brands like Andersen and Pella also make quality entry doors. Ask for the specific product approval or NOA number for any impact-rated door you're considering.
