Impact window lifespan in Florida
Quality hurricane impact windows last 20–30 years in Florida conditions when properly maintained. This is significantly longer than standard windows and longer than hurricane shutters, which typically need replacement or refurbishment every 10–15 years.
Lifespan by Frame Type
Vinyl frames: 20–25 years in Florida conditions. Can degrade faster with intense UV exposure in South Florida.
Aluminum frames: 25–35 years. More durable in Florida's sun and salt air. Generally longer-lasting than vinyl in coastal environments.
What shortens impact window lifespan in Florida
- Salt air corrosion — coastal homes within 1-2 miles of salt water see accelerated frame corrosion, particularly with aluminum frames that aren't properly coated
- UV degradation — Florida's intense UV exposure can degrade vinyl frames and window seals faster than in other climates
- Hurricane damage — impact windows are designed to survive hurricanes but extremely severe storms can damage the interlayer or frame
- Poor installation — improper installation can allow moisture intrusion that degrades frames and seals prematurely
- Lack of maintenance — neglected windows accumulate salt deposits and corrosion that accelerate wear
Signs your impact windows need replacement
- Fogging or condensation between glass panes — seal failure
- Visible cracks in the glass interlayer
- Frame corrosion or significant deterioration
- Difficulty opening, closing, or locking
- Drafts or water intrusion around frames
- Visible yellowing of the interlayer
How to extend impact window lifespan in Florida
- Annual cleaning — rinse frames and glass with fresh water to remove salt and dirt. Use mild soap for frames, never abrasive cleaners.
- Lubricate hardware — hinges, locks, and tracks should be lubricated annually with appropriate lubricant
- Inspect seals and caulking — check annually for gaps or deterioration around frames. Recaulk as needed.
- Coastal rinse after storms — rinse windows after tropical systems pass to remove salt deposits
