The Complete Window Maintenance Guide for Florida Homes

Impact windows are a significant investment — and like any investment in your home, they benefit from consistent maintenance. The good news: window maintenance is simple, inexpensive, and takes about an hour per year for most homes. Here's exactly what to do and when.

Twice Per Year: Clean the Frames and Glass

Florida's combination of salt air, pollen, and humidity means window frames and glass accumulate deposits faster than in most climates. Twice-yearly cleaning prevents buildup that becomes harder to remove over time.

For vinyl frames: Mild soap and water, soft cloth or sponge. Rinse thoroughly. Never use abrasive cleaners, acetone, or alcohol — they can dull or damage the frame finish.

For aluminum frames: Same approach, plus a wax or sealant application annually. This provides an additional barrier against salt air oxidation.

For glass: A squeegee and mild glass cleaner gives streak-free results. For stubborn salt deposits near coastal homes, a solution of white vinegar and water cuts through mineral buildup without damaging glass or Low-E coatings.

Annually: Inspect and Lubricate Hardware

• Locks and latches — Every window lock should engage smoothly and fully. Apply a dry silicone lubricant to moving parts (never WD-40 on window hardware — it attracts dust and degrades over time).
• Operators — Casement cranks should turn easily. If they're stiff, the mechanism needs lubrication or possible replacement.
• Sliding door rollers — Clean the track and lubricate rollers. Florida's salt and sand environment degrades roller function faster than in most climates.
• Hinges — Inspect for corrosion on any exposed metal hardware. Address early corrosion with a corrosion inhibitor spray.

Annually: Inspect Caulking and Weatherstripping

Caulk around exterior window frames degrades under UV exposure and thermal movement. Check for any cracks, shrinkage, or sections that have separated from the frame or wall surface. Recaulk any problem areas with a paintable silicone or polyurethane exterior caulk rated for Florida's climate.

Door weatherstripping — the seal at the bottom of the door (sweep) and around the frame — compresses over time. If you can see light around a closed exterior door, the weatherstripping needs replacement.

As Needed: Check Weep Holes

Window frames have small holes at the bottom designed to drain water from the track or sill. In Florida's environment, these can plug with debris, salt deposits, or insect material. Check them once or twice a year — a straightened paperclip clears them in seconds. Plugged weep holes are a leading cause of interior water intrusion.
