Window Condensation Problems in Arlington VA: Causes and Fixes

In Arlington VA, that shows up most often during cool mornings, wet shoulder seasons, and long stretches when the heat is on and the air inside stays too humid.

There are three places condensation can appear, and each one means something different.

• On the inside of the glass, which usually points to indoor humidity that is too high.
• Between the panes, which often means the seal has failed and the insulating gas has escaped.
• On exterior glass, which can happen when weather conditions are right for dew to form.

The inside-surface version is the most visible one, and it tends to show up in the same rooms where showers, cooking, laundry, and overnight breathing load the air with moisture. If you only see it once in a while, the window may be doing its job and the room may simply need better ventilation.

When Replacement Makes More Sense Than Repair
