Foggy Window Repair in Woodbridge, VA: What Causes It and How It Gets Fixed
Most homeowners see that cloudy film between the panes and assume the whole window needs replacing. It does not. What failed is the seal on the insulated glass unit inside your frame. Once that seal breaks, moisture enters the airspace between the panes and gets trapped there permanently. No amount of cleaning from the outside will reach it because the problem is locked inside the glass.
Here is what actually happened to your window:
The insulated glass unit, or IGU, is made up of two panes sealed around a gas-filled cavity. That gas, usually argon, improves the thermal performance of the window. When the seal fails, the gas escapes, humidity enters, and condensation forms on the inner surfaces. Temperature cycling between seasons accelerates the spread until the entire pane looks milky or streaked.
Builder-grade seals in homes built between 1990 and 2010 typically start failing between 10 and 15 years of use. South and west facing windows in Prince William County see even faster degradation because of direct afternoon sun exposure year round.
The fix is replacing only the glass unit inside the existing frame. The frame stays. The hardware stays. The cost is a fraction of a full window replacement and the result is a clear, properly insulated window again.
