How Humidity Affects Windows in Northern Virginia Homes

Humidity is one of those problems that homeowners notice first on the glass, then in the frames, and finally in the monthly comfort bill.

Over time, that movement can loosen caulk, stress seals, and expose weak points that were already hiding under paint or trim.

It is also why two homes on the same street can have very different results.

What Moisture Damage Usually Looks Like

If the water is forming between the panes, that usually means the seal has failed and the insulating glass unit is no longer doing its job.
