How to Budget for Commercial Glass Replacement in Florida

Budgeting a commercial glass replacement scope in Florida starts with four variables: scope size (square footage), glass package, aluminum finish, and schedule pressure. Multiply by 2026 per-square-foot ranges, add 15-20% contingency, and you have a working budget. Here is the math, by scope type.

Scope size: get the square footage right

Commercial glass replacement budgets stand or fall on accurate square footage measurement. Storefront: width × height for each opening, sum all openings. Curtain wall: total glass-and-frame envelope area. IGU replacement: count individual lites and measure each. Re-measure on site before finalizing budget — architectural drawings are within ±5-10% on existing buildings.

2026 per-square-foot ranges by scope

IGU replacement (same frame): $45-$95/sq ft installed.

Full storefront replacement: $95-$145/sq ft installed (non-HVHZ); $105-$165 in HVHZ.

Full curtain wall replacement: $135-$225/sq ft installed (non-HVHZ); $155-$245 in HVHZ.

Single-pane to IGU conversion: $75-$115/sq ft installed.

Frame finish refresh (no glass change): $35-$65/sq ft.

Adjustments by glass package

Solarban 70XL or Viracon VRE-67 in 1" IGU: baseline. Solarban 90 or premium architectural coating: +$8-$18/sq ft. SGP interlayer instead of PVB: +25-35% on glass line. Acoustic interlayer or laminated for sound: +$12-$25/sq ft. Custom-tinted or specialty glass: +$15-$35/sq ft.

Adjustments by aluminum finish

Standard PVDF Kynar in stock color: baseline. Custom PVDF color match: +12-20%. Anodize Class II: +5-10%. Anodize Class I: +12-18%. Powder coat: -8-15% (typical lower cost, shorter service life). 2-tone PVDF (interior different from exterior): +20-30%.

Contingency reserve

Add 15-20% contingency for: substrate conditions revealed at install, schedule pressure (after-hours scope premium), AHJ rework on submittal package, hidden frame damage discovered during glass removal. Owners who skip contingency get blindsided by change orders.

Frequently asked questions

Does insurance cover commercial glass replacement budgeting?

Storm and impact damage typically covered by commercial property insurance subject to deductible. Wear-out (IGU edge seal failure, sealant aging) typically not covered. Budgeting differs: insurance scope is reactive; capital improvement scope is planned.

How long after budgeting can construction start?

Budget today, bid in 48 hours on complete RFQ package, submittal package 10-15 business days after contract award, material lead time 8-16 weeks typical, install per project schedule. Total elapsed: 12-24 weeks for new construction commercial replacement.

What if the budget is significantly under what bids come in at?

Re-spec to value-engineer: approved-equal aluminum, alternate glass package, schedule flexibility, phased install. Or expand budget. Or postpone scope. Worth a 30-minute conversation with a qualified glazier before any of these.
