Repair before replacement

Most window faults are cheaper to fix than to replace

A blown sealed unit is a glass problem. A draught is usually a gasket. Faded frames are a finish, not a failure. Below, each common fault has its own guide covering causes, the fix we'd recommend, what to check yourself first, and typical cost — written for individual towns rather than as a generic template.
