Impact Glass Replacement Cost in Florida (2026)
If your impact window's frame is fine but the glass is cracked, foggy, or failed, you usually don't need a whole new window — just the glass unit. Here's what glass-only replacement costs in South Florida, what drives the price, and when it's the smart move.
The short answer
Glass-only (IGU) replacement runs $250–$600 for most residential impact windows in South Florida — versus $500–$900+ for a full window. You save the most when the frame is sound and the matching glass is in stock.

What Drives the Price
Glass size
Bigger units cost more in both material and labor — pricing scales with square footage.
Glass type
Clear laminated is cheapest; insulated, low-E, tinted, and obscure impact glass add cost.
Brand & stock
If the matching IGU (PGT, ESW, Mr. Glass) is in stock, you skip the custom factory order and markup.
Permit & re-inspection
Florida requires a permit; some jobs need a re-inspection to keep the NOA and insurance discount valid.
When Glass-Only Replacement Is Possible
- The frame is undamaged and structurally sound (almost always the case with fog or a cracked outer pane).
- A matching IGU size is available in stock or from the manufacturer.
- The original product's NOA / Florida Product Approval is still current.
- No frame hardware, track, or weatherstripping damage.
If the frame is bent, the product is discontinued, or the NOA expired, a full in-stock window replacement is the better value — and still 30–60% below custom retail through Windows Stock Market.
Frequently Asked Questions
How much does it cost to replace just the glass in an impact window?
In South Florida in 2026, replacing only the insulated glass unit (IGU) of an impact window typically costs $250–$600 total — roughly $150–$400 for the glass unit plus $100–$200 labor, depending on size and glass type. That's far less than $500–$900+ for a full window replacement. Glass-only replacement is possible when the frame is sound, the size is available, and the product's NOA is current. Buying the replacement glass in-stock through Windows Stock Market cuts the material cost 30–60%.
Is it cheaper to replace the glass or the whole impact window?
Glass-only replacement is almost always cheaper when the frame is undamaged — often less than half the cost of a full window. A full window replacement makes sense only when the frame is bent, warped, or corroded, the product is discontinued, the NOA has expired, or the replacement glass size isn't available. A free assessment confirms which path fits.
What affects the cost of impact glass replacement?
The biggest factors are size (square footage of the glass), glass type (clear laminated vs insulated, low-E, tinted, or impact-rated obscure glass), the brand and whether the matching IGU is in stock, access and floor level, and whether a permit and re-inspection are required. Laminated impact glass costs more than standard glass because of the certified interlayer.
Does replacing impact glass require a permit in Florida?
Yes — glass and window work in Florida generally requires a building permit, even for a like-for-like glass unit replacement, so the work stays code-compliant and your insurance discount and warranty are protected. Vieser Construction handles permitting and any required re-inspection as part of the job.
Can I save money by supplying my own impact glass?
Yes. Because Windows Stock Market is a marketplace of in-stock impact glass and windows, you can source the matching IGU at wholesale instead of paying a custom factory order and markup — typically 30–60% less. Send the exact size and glass type and we'll check inventory, then Vieser Construction installs it with the permit.
