Repair or replace?
A sound frame with a faulty component may be suitable for repair. A failed glass unit does not automatically mean replacing the whole window. The frame condition, damage and availability of compatible parts determine the options.
When you call, have your postcode, a description of the fault and the number of affected windows ready. Mention difficult access and any window or door that cannot be secured. Ask how best to send photographs.
There is no fixed repair price here: the team provides a free, no-obligation quotation for the work assessed.
Discuss your repair with the teamIs condensation always a failed double-glazed unit?
No. Moisture on an accessible glass surface can be surface condensation. Misting trapped between the panes may indicate a failed sealed unit. Tell the team where the moisture appears.
Can I keep using a sash window that drops?
Stop using a dropping sash and keep people clear until it has been assessed. A balance or supporting mechanism fault needs the correct parts and assessment.
What determines the cost of a window repair?
The fault, compatible parts, number of windows and access affect the quotation. A component repair may be suitable if the frame is sound. Ask for a free, no-obligation assessment and quotation.
