Cost summary
Installed price ranges (Florida, 2024–2026)
| Opening / scope | Installed range | Notes |
|---|---|---|
| Front door (single opening) | $2,200–$4,800 | Width, threshold type, and custom color drive variance. |
| Garage (single-car opening) | $2,800–$6,500 | Panel count and track mounting affect total. |
| Garage (two-car / wide opening) | $4,500–$12,000 | Often requires multi-panel deployment and heavier anchors. |
| Sliding / patio door | $2,400–$5,500 | Track adapters and sill geometry add labor. |

Methodology — Installed ranges reflect Florida residential quotes (2024–2026): aluminum modular barriers, EPDM seals, standard openings. Excludes major structural retrofit, engineered floodwall systems, and emergency surge pricing. See /methodology for full methodology.
The cost of being wrong in a flood often exceeds the cost of a properly measured barrier system. This page is the canonical reference for residential installed ranges—replacing fragmented FAQ and blog figures.
Most homeowners budget per opening (door, garage, patio) rather than a single SKU price.
Best fit for
- Single-family homes with 1–4 flood-prone openings
- Owners who want reusable dry-floodproofing vs sandbags
Not recommended for
- Below-grade living without engineered wet floodproofing plan
- Expecting permanent floodwall pricing from deployable ranges
Frequently asked questions
What is the cheapest opening to protect?
Standard front doors are often the lowest per-opening install; wide garage openings drive totals.
Does price include installation?
Yes—the table shows installed ranges including typical labor.
Why do blogs show $899 barriers?
That may reference a component or promo SKU—not a measured, installed opening. Use this page for planning.
Will NFIP pay for barriers?
Mitigation discounts may apply with compliant floodproofing documentation—see insurance benefits FAQ.
How do I get an exact quote?
Schedule measurement—width, sill, and anchors determine final price.
