Common Window Condensation Problems in Arlington VA Homes

What Window Condensation Usually Means

Window condensation is one of those problems that looks simple until you pay attention to where the water is sitting.

If the water is on the room side of the glass, the house is often holding more humidity than the window can handle on a cold morning.

Moisture trapped between the panes is a sign the insulating seal has failed, and cleaning will not fix it.

A window can look wet from the outside and still be performing exactly as designed.

Around Arlington VA, you will see everything from newer double pane windows to older sash units, and each type handles condensation a little differently.

Why Condensation Shows Up In Arlington VA Homes

The most common cause is excess indoor moisture trapped inside a relatively tight house.
