Misted And Failed Units
The seal between the panes has gone and moisture is trapped inside. We replace the sealed unit, not the window.
Same frame retained
Most repairs done in one visit
Your windows probably do not need replacing.
A misted pane does not mean a new window. Neither does a stiff handle. We fix what can be fixed, and tell you plainly when replacing is the better spend.
- Misted and failed double glazing units replaced
- Handles, hinges, locks and friction stays
- Draughty or perished seals resealed
- Timber sash repairs in period properties
What We Fix
Nine times in ten, the frame is fine.
The frame usually outlives the parts bolted to it. Sealed units, handles, hinges and gaskets are all replaceable items, and swapping one costs a fraction of a new window.
The glass, not the windowA failed unit is lifted out from inside and a new one dropped into the same frame. The window you already have stays where it is.
Handles, Locks And Espagnolettes
Stiff, snapped or spinning handles, and the locking bar behind them. Usually a same-visit fix.
Fixed in one visitHinges And Friction Stays
Windows that drop, catch or will not stay open. Friction stays wear and are a straight swap.
Straight swapPerished Seals And Draughts
Gaskets shrink and crack with age. New seals stop the draught without touching the glass.
Draught stoppedTimber Sash Repairs
Rot in the bottom rail of a sash window is usually a splice repair, not a new window. Important in conservation areas.
Splice repairedCondensation Diagnosis
Water on the inside of the pane is a ventilation problem. Between the panes is a failed unit. They need different answers.

Common Questions
Window repair questions we get asked
Can misted double glazing be fixed without replacing the whole window?
Yes, in almost every case. The misting is a failed seal in the glass unit itself, so we lift out the old sealed unit and fit a new one into the frame you already have. The frame, sash and hardware all stay.
How much does it cost to replace a misted unit?
It depends on the size and the glass specification, but it is a fraction of a new window. We measure and give you a clear quote before any work starts.
My window is draughty but the glass is fine. What is wrong?
Usually the rubber gasket has perished and shrunk, or the hinges have dropped so the sash no longer pulls tight to the frame. Both are inexpensive fixes.
There is condensation on the inside of my window. Is that a failed unit?
No. Water on the room side of the glass is a ventilation and humidity issue, not a glazing fault. Condensation trapped between the panes is the failed unit. We will tell you which you have.
Do you repair timber sash windows in tenements?
Yes. Rot in the bottom rail is usually repaired by splicing in new timber rather than replacing the sash, which matters in a conservation area where replacement may not be permitted.
Do you charge for the assessment?
No. The assessment and the quote are free, with no obligation.
