Failed sealed units replaced
Misted double glazing repairs in Essex.
If condensation is trapped between the panes, the sealed unit has failed. A&E Window Doctor replaces misted double-glazed units across Essex without pushing full-frame replacement where the frame is still sound.
Why has my double glazing gone misty?
Misted double glazing usually means the sealed glass unit has failed and moisture has entered between the panes. The frame may still be usable, so the practical fix is often to replace the sealed unit rather than the whole window.
What customers notice first
The glass looks cloudy, foggy or permanently wet inside the unit. Cleaning the outside will not clear it because the condensation is trapped between the panes.
How the repair works
The unit is assessed, measured and replaced with a new sealed unit that fits the existing frame. This gives the customer a targeted repair and avoids unnecessary disruption where the frame is still in good condition.
Where this page fits
This is one of the highest-intent problem pages because customers know the symptom before they know the trade term. It links naturally into glazing replacement, window repairs and double glazing repair pages.
What this service usually involves
Double glazing repair is a broad search intent, so the page separates glass failure from hardware failure. A misted unit normally points to sealed-unit replacement, while stiffness, draughts or poor closing can point to hinges, locks, seals or alignment.
How customers can describe the fault
This distinction helps customers avoid the common trap of assuming all double glazing faults need new frames. In many cases, targeted repair restores the unit, opening or door without turning the job into a full installation project.
Repair or replace: the decision rule
A repair is normally preferred when the frame, sash or door is still sound and the failed item is a part, sealed unit, lock, hinge, handle, roller, barrel or seal. Replacement becomes the better answer when the structure, security, finish or long-term performance cannot be restored by targeted work. That distinction is important for Misted double glazing repairs because it protects customers from paying for unnecessary full replacement.

Not always. If the frame is in good condition, replacing the glass unit is often enough.
