How to Tell if Your Windows Are Failing from Florida Heat and Humidity

How Heat And Humidity Wear Windows Down

In Florida, windows take a beating from long stretches of heat, heavy humidity, salt air, and storms that never really let materials rest.

If you catch failure early, you may be dealing with one window, one seal, or one frame problem instead of a larger water intrusion or insulation issue.

Opening and closing problems also matter.

Look at the caulking and the perimeter around the window as well.

A Few Signs That Usually Point To Failure

• Moisture sealed inside the glass layers
• Noticeable heat gain near the window
• A loose fit or weakened seal
• Sticking, binding, or locking problems
• Possible perimeter leakage
