Condensation Between Window Panes in Arlington VA: What It Means

Why Window Seals Fail In The First Place

Over time, that movement weakens the perimeter seal and allows moisture to creep in.

A few conditions show up again and again in the field:

Seal breakdown from simple wear over time Slight shifting in the frame that stresses the seal Repeated heat and cold cycles, especially on sun-exposed elevations An early manufacturing or installation weakness Physical damage, even if it was minor and happened years ago

The sash, frame, and hardware may still be in decent shape while the insulated glass unit has gone bad.

If the moisture is trapped where you cannot reach it, the seal has likely breached.

Repair, Glass Replacement, Or Full Window Replacement?
