Foggy Window Repair That Restores Clear Views & Energy Savings
Cloudy glass, condensation between panes, or a failed window seal? Our certified glaziers defog and replace insulated glass units (IGUs) for homes, businesses, HOAs, and property portfolios — usually the same day, at a fraction of full replacement cost.

TL;DR — Foggy Window Repair at a Glance
Foggy windows are caused by a failed insulated glass seal. You do not need to replace the whole window — in most cases we defog the pane ($85–$175) or swap the insulated glass unit ($175–$385) while keeping your existing frame. Repairs take under 2 hours per window, restore up to 50% of lost R-value, and cost 60–80% less than full window replacement. Call (877) 356-8839 for a free on-site quote.
Signs You Need Foggy Glass Repair
A cloudy or hazy window is more than a cosmetic problem — it's the first visible sign that your insulated glass unit (IGU) has failed. Watch for these red flags:
- Persistent fog, haze, or cloudiness between the two glass panes
- Water droplets or condensation that will not wipe away
- White chalky mineral streaks or "rain trails" on the inside of the glass
- Visible distortion or a wavy appearance in the glass
- Cold spots or drafts near the window frame
- Rising heating and cooling bills without other explanations
