Misted Double Glazing Repair Cambridge
SJC Glass
Replacement of misted or blown double glazing units in Cambridge. SJC Glass replaces failed sealed units in UPVC and aluminium windows.

Signs Your Double Glazing Unit Has Failed
Misted double glazing is usually caused by a failed sealed unit. When the seal breaks, moisture can enter between the panes of glass, creating condensation that cannot be wiped away.
Common signs include:
• Condensation or mist between the glass panes
• Windows that appear cloudy or steamed up
• Water droplets trapped inside the glass
• Reduced insulation or colder rooms near the window
If you notice any of these problems, the sealed unit inside the window may need replacing. In most cases the entire window frame can remain in place while the glass unit is replaced.

Why Replace the Sealed Unit Instead of the Whole Window
When double glazing becomes misted, many people assume the entire window needs to be replaced. However, in most cases only the sealed glass unit needs changing.
Replacing the sealed unit is often a quicker and more cost-effective solution. The existing window frame remains in place while the failed glass unit is removed and replaced with a new energy-efficient unit.
At SJC Glass we replace misted double glazing units in UPVC and aluminium windows and doors across Cambridge and surrounding areas, restoring the appearance and insulation of your windows without the need for a full replacement.
