How to Spot Failing Window Seals in Louisiana Humidity

Why Window Seals Fail So Often In Humid Weather

Windows in Louisiana take a beating from heat, moisture, and constant seasonal swings. A window seal is meant to hold the insulated glass unit together and keep the airspace dry. When that seal starts to fail, the glass often tells the story before the frame does.

What Failed Window Seals Look Like In Real Life
