What does it cost to fix a foggy dual-pane window?
Costs & Estimates · Answered by Lake Tahoe Glass, the CA shore’s glass shop.
The short answer
If the frame is good, you replace only the sealed glass unit — typically $150–$400 per unit nationally, versus $450–$1,000+ for a whole new window. Multi-window jobs usually price better per unit.
The full picture
Fog between the panes means the insulated glass unit (IGU) failed — and the fix is swapping that sealed unit inside your existing frame. National figures put IGU-only replacement around $150–$400 per unit for common sizes, while full window replacement typically starts around $450–$1,000+ per opening before you're into premium products.
That gap is why our first question is about your frames, not your glass. Sound frames: unit swap, most of your money saved. Rotten or failing frames: we'll say so, and quote a proper replacement — as an Andersen PREMIER Certified Contractor we do those right, but we won't sell you one you don't need.
One Tahoe-specific note: the replacement units we order are built for altitude. A sea-level unit installed at 6,200 feet starts life with stressed seals — the very failure you're paying to fix. Details in our altitude glass answer.
Fogged units tend to fail in cohorts (same age, same sun exposure), so if three windows are milky, have us look at the whole elevation while we're there — multi-unit orders price better per window.
