Foggy Glass Repair in Thornhill
Thornhill straddles the Vaughan-Markham border, and its housing reflects that dual character: established mid-century brick bungalows along Centre Street, large estate homes in Royal Orchard, and modern townhomes near the Promenade. Many of these homes carry original double-pane windows now well past their seal lifespan. LuminaSky restores foggy windows across Thornhill by replacing only the sealed glass unit, leaving frames and trim untouched.
How Sealed Glass Unit Failure Works
A sealed glass unit (the industry calls it an IGU, insulated glass unit) is two or three panes of glass separated by a spacer bar and sealed at the perimeter. The space between is filled with argon or krypton gas and desiccant beads that absorb moisture.
When that seal breaks down: argon gas escapes, outside air seeps in bringing moisture, and the desiccant saturates. Once saturated, condensation forms between the panes: the familiar 'foggy window' look. From that point, the fog will never clear on its own.
The frame, sash, and hardware are usually still fine. Only the sealed glass unit needs replacing. That's why we can restore a foggy window for 60–80% less than a full window replacement.
