How often you replace your windows in Florida depends on more than just the age of the window. Our climate in the Sunshine State is tough on homes. Between relentless sun, salty air, humidity, and hurricane season, windows in Florida work a lot harder than windows in most other parts of the country.
Have you been wondering, “How often should you replace windows in Florida?” It helps to think in terms of both time and symptoms to determine if it’s time for a window replacement. That way, you can make upgrades before small problems turn into bigger problems and expensive damage.
Typical Florida Window Replacement Timeline
In many parts of the country, quality windows can last 25–30 years or more. In Florida, the story is a little different because of Mother Nature. The combination of UV exposure, coastal conditions, and storms often means a shorter practical lifespan.
For many homes, a realistic Florida window replacement timeline falls somewhere around 15–20 years for older, non-impact windows. That does not mean every window suddenly fails at year 16. Instead, it is the point where efficiency typically drops, seals wear out, and frames start to show their age.
Newer impact windows with modern materials and proper installation can often perform well beyond 20 years, especially if they are maintained. However, if your home still has original builder-grade windows from the 1990s or early 2000s, there is a good chance you are overdue for an upgrade.
Why Florida Windows Wear Out Faster
Florida’s climate definitely speeds up wear and tear on your home. Strong UV rays break down older frame materials and dry out weatherstripping. High humidity and driving rain test seals constantly. In coastal areas, salt in the air can corrode metal components and hardware.
The Federal Emergency Management Agency (FEMA) notes that high-wind regions benefit from stronger, better-protected window systems to reduce storm damage and water intrusion. That guidance lines up with what homeowners see in practice: older, weaker windows simply do not stand up to repeated storm seasons as well as modern, impact-rated options.
So, when you ask, “How often should you replace windows in Florida?”, part of the answer comes down to how much abuse your specific home takes from weather, sun, and salt.
Signs It Is Time To Replace Your Windows
Age is only one piece of the puzzle. The condition of your windows tells the rest of the story. You may not know the exact year they were installed, but you can look for clear warning signs.
If you notice regular condensation between the panes, the seal has likely failed. If you feel hot air pouring in around the frame in summer, or cold drafts in winter, the window is no longer doing its job. Sticky sashes, rotting or soft wood, cracked glass, or visible gaps around the frame are other signals that it is time to think about a replacement.
Noise is another clue. If outside traffic, neighbors, or yard equipment sound much louder than you think they should, your windows may not be providing much insulation at all. That is common with older single-pane units.
Safety, Codes, And Storm Protection
In Florida, you also need to think about building codes and storm readiness. Over time, codes update to reflect better storm data and improved standards. If your windows predate major code changes or were installed before your area adopted stricter hurricane requirements, they may not offer the level of protection you assume.
Many homeowners use the first major renovation, roof replacement, or exterior project as a trigger to reevaluate their windows. It is often more cost-effective to combine projects and bring everything up to current standards at once instead of doing piecemeal fixes.
Planning Your Florida Window Replacement Timeline
Practically speaking, a good rule of thumb is to start seriously evaluating your windows around the 15-year mark, especially if you live in a coastal or high-wind zone. From there, you can decide whether to replace them all at once or work in phases.
If you already see leaks, drafts, or damage, you do not need to wait. The right new impact windows can improve comfort, support better energy efficiency, and give you more confidence heading into hurricane season.
