Why Brandon FL Humidity Makes Windows Sweat

A few common conditions make the problem worse:

• The home is kept very cool while the outside air stays hot and damp.
• Steam and everyday humidity build up inside and eventually show up on windows.
• Thin glass and leaky frames make surfaces colder and more prone to condensation.
• Warm, moist outside air can get pulled inside around frames, sliders, and doors.
