Why Has My Double Glazing Misted Up?

Every double glazed unit is sealed around its edge and filled with air or gas. Over time that seal breaks down, letting moisture creep in between the panes. Once condensation forms inside the glass it cannot be wiped away or dried out – the unit itself has failed and needs replacing.

Misted units are not just unsightly. A failed unit has lost its insulating gas, so it lets more heat escape and your energy bills creep up.

Repair, Not Replacement

Window companies will often try to sell you complete new windows. In most cases that is unnecessary. We remove the failed sealed unit and fit a new A-rated glass unit into your existing uPVC, aluminium or timber frame – typically for a fraction of the cost of new windows.

We survey and measure on our first visit, and your replacement unit is normally manufactured and fitted within a week, or quicker for emergencies.

Before and After: Misted Units We’ve Replaced

These are real jobs, not stock photos. In each case we replaced only the failed sealed unit — the frames stayed exactly as they were, and each new unit took under 30 minutes to fit.
