Double glazing repairs in Cardiff
Where a Cardiff frame is sound but a sealed unit has misted or a mechanism has failed, a repair costs a fraction of replacement and is usually one visit. Blown seals on the 1990s and 2000s uPVC across Rhiwbina, Whitchurch and Llanishen are the most common call.

Frequently asked questions
Can a misted unit be repaired without a new window? Yes - it is a glass-unit swap and the frame stays in place. Around £78 to £264 per unit in Cardiff using the local 0.88x factor.
Blown seal or condensation? A blown seal mists permanently between the panes and can’t be wiped. Room-side condensation is a ventilation problem, not a glazing fault.
How quickly can you come out? Same week for most repairs; sooner for a window that will not lock or close.
