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.
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.
Why are my windows steamed up on the inside?
This is the question most people actually type, and the answer depends on where the steam sits. If the misting is between the two panes and won't wipe off, the sealed unit has failed and moisture is trapped inside the glass — that needs a replacement unit. If you can wipe the steam away from the room-side surface, it is everyday condensation from cooking, drying washing or humidity, and the glass itself is fine. The trapped kind is the one we repair.
Steamed up, foggy, cloudy or blown — same problem?
Customers describe it in lots of ways: steamed up, foggy, cloudy, hazy, misty or "blown" double glazing. They almost always mean the same thing — a sealed glass unit that has lost its seal and let moisture in. Whatever you call it, the fix is the same: measure the failed unit and fit a fresh sealed unit into the existing frame.
Can steamed up or foggy windows be fixed without a new window?
Yes, in the great majority of cases. Where the frame is sound and the window still opens and locks normally, only the glass unit is replaced — not the whole window. Replacing the frame is only worth considering if it is rotten, warped or insecure, which is uncommon on otherwise healthy uPVC windows. This is the repair-first approach: deal with the failed part, keep what still works.

What this service usually involves
Double glazing problems fall into two types — glass failure and hardware failure — and each needs a different fix. 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.
The failed sealed unit is usually replaced. That restores the glass while keeping the existing frame if it is still sound.
Is condensation inside double glazing normal?
No. Condensation between panes usually means the seal has failed and moisture has entered the unit.
Do you need to replace the whole window?
Not always. If the frame is in good condition, replacing the glass unit is often enough.
Why are my windows steamed up on the inside of the glass?
Steaming between the panes that won't wipe off means the sealed unit has failed. Steam you can wipe off the room-side surface is just everyday condensation, not a fault.
Can foggy or steamed up windows be fixed?
Yes — a new sealed glass unit is measured and fitted into the existing frame, so the glass is clear again without replacing the whole window.
How much does it cost to fix misted double glazing?
A typical A&E guide is from £65 per unit fitted, or from £400 for several units or a whole house in one visit. Your exact quote is free after inspection.
