Professional foggy window repair and insulated glass unit replacement for homeowners near the Chain Bridge Road corridor and McLean's established residential neighborhoods. We fix cloudy, hazy, and moisture-damaged windows without replacing the whole window.
If you're seeing foggy, cloudy, or hazy glass in your McLean home, the problem is almost always a failed window seal — not dirty glass. Homeowners near the Chain Bridge Road corridor and McLean's established residential neighborhoods call us when they notice condensation or moisture trapped between their window panes.
The good news: in most cases, you don't need to replace the entire window. We replace only the insulated glass unit (IGU) inside your existing frame — saving McLean homeowners 60–80% compared to full window replacement.
McLean has one of the widest ranges of window age in Northern Virginia — long-established neighborhoods with original or first-generation replacement windows sit alongside newer custom-built and rebuilt homes, so we see everything from decades-old original glass to recently installed units already showing early seal issues.
The Northern Virginia climate — with its hot humid summers and cold winters — puts significant stress on window seals everywhere in the region. Once the hermetic seal of your insulated glass unit fails, outside humid air enters between the panes and creates that characteristic foggy, cloudy appearance. This is 100% a broken window seal issue, not dirty glass — the condensation can't be cleaned away because it's inside the sealed unit.
Yes, custom and oversized window glass is common work for us in McLean; we measure each opening individually rather than assuming a standard size.
Seal failure can happen within the first decade on some units, especially lower-quality replacement glass, so it's not exclusively an older-home problem — though it's more common past the 15-20 year mark.
