Double Glazing Repairs in Leicester
Many problems with double glazing can be fixed without replacing the whole window, which saves a lot of money.
Common repairs
- Misted or foggy glass. The seal of the glass unit has failed and moisture has got between the panes. The unit can usually be replaced on its own, keeping the frame.
- Handles and hinges. Stiff, loose or broken handles and worn friction hinges are cheap to replace.
- Locks. Door locks that are hard to turn, or a failed multi-point gearbox, can be replaced. Upgrading to an anti-snap cylinder is worth doing at the same time.
- Draughts. Worn seals and gaskets can be renewed and windows adjusted.
- Dropped doors. A uPVC door that catches on the frame can usually be realigned.
What repairs cost
As a guide, Checkatrade's published data for Nottingham in October 2026 puts a typical double glazing repair at around £190 to £390, with an average of about £270. A single misted unit or a new handle is usually less; a door gearbox or several units more.
Repair or replace?
If the frames are sound and the windows are less than about 20 years old, repairing is usually the better value. If several units have failed, the frames are discoloured or warped, or the house is cold despite the double glazing, getting a quote for new windows as well lets you compare.
Common questions
Can I just replace the misted glass?
In most cases, yes. The installer measures the sealed unit and fits a new one in the same frame.
Are repairs covered by my guarantee?
If the windows are still within the installer's guarantee, contact them first. Many guarantees cover failed sealed units for ten years.
