Foggy, hazy glass panels on a commercial skylight or atrium are usually a seal problem, not a structure problem. When the seals on insulated glass units fail, the fix is to replace the failed glass while keeping the sound frame. On a commercial roof with many panels, doing only the ones that have actually failed is the cost-effective move.
What seal failure looks like
An insulated glass unit is two panes with a sealed space between them. When that edge seal breaks down, moisture gets in and you see permanent fog or condensation between the panes that cannot be cleaned. The unit loses clarity and insulating performance. On a big glazed roof, a scattering of fogged panels stands out and drags down the whole look.
The cost-effective approach
- Replace only the failed units. The sound panels stay. You pay for the glass that actually needs it.
- Match the existing glass so the roof looks uniform again.
- Upgrade while you are at it if you want low-E or laminated glass in the replacements.
Why this beats full replacement: When the frame and structure are sound, replacing the entire skylight system is a lot of money to solve a glass problem. Targeted reglazing of the failed units gets you clear glass again for a fraction of that.
How pricing works
Priced per project based on how many units have failed and access to the roof or atrium. We survey first and quote the actual scope, not a flat per-panel rate.
How it goes
We survey the glazing, identify every failed unit, confirm the frame is sound, and quote replacing the failed glass. See the commercial overview for the rest of the rooftop scope we handle.
