Window Repair Questions

If the fault is with the glass, seals, hinges, locks, or a localised frame crack, repair is usually possible. Full replacement becomes necessary when the frame is badly warped, structurally weak, or has failed across its full length. The on-site survey will tell you which applies.

Yes, in most cases. Blown double glazing is caused by a failed sealed unit. The unit is replaced with a new double-glazed pane sized to the existing frame. If the frame and hinges are still sound, only the glass unit needs attention.

No. Misting between the panes means the sealed unit has failed, not the frame. The frame, handles, and hinges are often still in good condition and can be reused once the sealed unit is swapped out.

A cracked pane is a security and safety risk and can worsen with temperature changes. A draught left unaddressed allows heat loss and moisture ingress, which can lead to frame deterioration and higher energy bills over time.

Minor cracks, movement, and fitting issues can often be repaired or adjusted in place. If the frame is split along its length, badly warped, or no longer holds the glazing securely, the installer will advise on replacement as the safer option.

The written quote lists each component, glass or sealed unit, sealant, hinges, locks, alongside labour and waste removal as separate line items. Both repair and replacement costs are set out where relevant, so you can compare before committing.
