Impact Window Repair: What Can Be Fixed, and When to Stop Fixing
Impact windows are built to take punishment, but nothing built by humans is maintenance-free: seals fail and glass fogs, balances tire, rollers flatten, locks wear, and sometimes laminated glass does exactly its job, cracking but holding, and needs a unit swap afterward. The repair conversation in Florida is plagued by two bad actors: companies that only sell replacement (so everything "needs" replacing) and handymen who void ratings with non-approved glass. Here is the honest middle: what is genuinely repairable, what it costs, and when replacement really is the answer.
Impact Window Repair by Florida Impact Shield: Licensed assessment, approved-specification repairs, seal failures, glass units, hardware, and straight answers when repair stops making sense.
The Repairable List
Seal failures (foggy glass): the insulated glass unit is replaced within your existing frame, restoring clarity and efficiency at a fraction of window cost. Laminated glass damage: cracked-but-holding impact glass gets a unit swap to matching approved glass, restoring full rating. Hardware: balances that no longer hold sashes, worn rollers on sliders, failed locks and cranks, tired weatherstripping, all routine, all parts-dependent. The gating question across every category is parts availability for your product line, which our assessment answers before anyone spends money.
The Replace-Instead List
Some conditions end the repair conversation honestly: frames corroded or water-rotted (the structure the rating depends on is gone), obsolete lines with no parts channel, chronic leakage tracing to failed installation rather than components, and the economics case, when several windows each need glass and hardware, per-opening repair totals can approach replacement pricing that resets warranties and efficiency entirely. We show the arithmetic both ways and let you decide.
Typical Repair Costs
| Repair | Typical Range |
|---|---|
| Insulated glass unit (seal failure) | $250 - $700 per unit |
| Laminated impact glass unit | $350 - $900 per unit |
| Balances / rollers / locks | $100 - $350 per window |
Ranges vary by size, product line and access; exact pricing follows assessment. Where repairs cluster, we quote the replacement alternative beside them, one visit, both answers.
Protecting Your Ratings and Credits
The cardinal rule: repair to the approved specification. Swapping impact glass for ordinary glass, or leaving a damaged unit unaddressed, undermines both your protection and the wind mitigation status behind your insurance discounts. Licensed repairs with matching approved components keep your wind mitigation documentation intact and your up-to-35% credits safe.
Book a Repair Assessment
A licensed assessor visits, diagnoses every problem opening, checks parts availability, and delivers repair pricing, with the replacement comparison included wherever the math gets close. Honest fixes, protected ratings, no pressure.
Frequently Asked Questions
Can foggy impact windows be repaired?
Fog between panes means the insulated glass seal has failed. The fix is replacing the glass unit (IGU) within the existing frame, a genuine repair far cheaper than window replacement, available when matching approved glass is obtainable for your product line.
My impact glass is cracked but intact, is that normal?
Yes, that is laminated glass doing its job: it cracks but holds together, keeping the envelope sealed. The glass unit should be replaced to restore full rating, but your home was never breached, which is the entire point of impact glass.
What impact window problems are worth repairing vs replacing?
Repair-worthy: seal failures, broken balances and hardware, rollers, locks, weatherstripping, and single glass units in otherwise sound windows. Replace-worthy: corroded or water-damaged frames, obsolete product lines without parts, and homes where per-window repair costs approach replacement economics.
Will repairs affect my insurance credits?
Properly repaired impact windows retain their protection status. What threatens credits is replacing impact glass with non-rated glass or leaving openings unprotected, always repair to the approved specification, which a licensed contractor documents.
