What is actually being replaced in St. Augustine
St. Augustine is the nation's oldest continuously occupied European settlement, with housing that ranges from 17th–19th-century historic singles downtown to mid-century singles in West Augustine to 2000s–2020s subdivisions on the south and west edges. Window scopes vary dramatically by area.

Greater Jacksonville housing stock and conditions
Duval and Clay counties hold substantial 1950s-1970s concrete-block ranches with original aluminum single-pane windows, and St. Johns County adds a fast-growing 2000-2020 subdivision belt with impact-rated or standard dual-pane vinyl.
Coastal and near-coastal exposure brings Florida Building Code impact requirements into play for many replacement jobs, and concrete-block openings often need different anchoring than wood-frame construction elsewhere.
- Impact-rated window replacement is specified in most coastal and near-coastal Duval and St. Johns County jobs
- Original single-pane aluminum windows in 1950s-1970s concrete-block ranches remain a large replacement segment
- Retiree-driven low-maintenance vinyl and fiberglass conversions are rising in Clay and St. Johns
What a window project costs in St. Augustine, FL in 2026
Construction costs in Greater Jacksonville run about 7% below the national average. The ranges below take national project anchors and apply that local index, so they reflect what local crews actually quote rather than a national average that fits nowhere.
Costs run below national, and coastal wind-load code shifts where the money goes: more into impact-rated glass and reinforced frames, less into basic single-pane replacement.
Midpoint of the typical range for each project type.
| Project | Greater Jacksonville range | National range |
|---|---|---|
Partial replacement (6 openings) The worst half-dozen windows swapped as same-size inserts, usually the drafty street-facing elevation first. | $3,500 – $8,500 | $3,500 – $9,000 |
Whole-home vinyl replacement Every opening replaced in one pass with mid-range Low-E vinyl inserts, existing frames kept where sound. | $8,500 – $18,500 | $9,000 – $20,000 |
Whole-home fiberglass or wood-clad Same coverage in a premium frame material, narrower sightlines and paintable exteriors, often part of a facade update. | $15,000 – $35,500 | $16,000 – $38,000 |
Full-frame tear-out (8 openings) Frames, sills, and trim removed to bare rough opening so rot can be repaired and the opening flashed and insulated properly. | $7,500 – $18,500 | $8,000 – $20,000 |

Any St. Augustine window project that enlarges a rough opening, alters a header, or changes an egress window needs a permit. In Florida that goes through the County or city building department.
Typical permit cost for a window project: $150–$600 for a window replacement permit. Confirm current fees with your local office before signing a contract, and make sure the contractor pulls the permit, not you.
How St. Augustine compares with the national picture
The national direction is consistent everywhere: Low-E coated, gas-filled glass is the baseline spec, vinyl takes most openings with fiberglass gaining at the top of the market, and insert replacement handles same-size openings unless the sills have failed. What changes locally is how much of that work is triggered by failure versus choice, and how much the same scope costs.
