Window sash repair cost rarely goes up to £350. This price includes expert woodwork, treatment of window’s damaged areas, their replacement if needed, as well as refurbishment and professional painting. Chameleon decorators, for example, use top quality materials in their work, thanks to which your sash window may endure more than 7 years without any maintenance.
Window replacement requires multiple concerns – new window purchase, its installation price, and the maintenance services like painting or weatherization. This whole mass of operations will cost you no less than £1,500 – not really advantageous comparing to sash window restoration.
