Sash Window Experts in Clapham
Period homes across Clapham are defined by their original timber sash windows, and our secondary glazing is engineered to protect them. Rather than replacing irreplaceable joinery, we install discreet vertical-sliding panels behind the existing sashes, retaining the proportions and sightlines that give Clapham properties their character while delivering modern thermal and acoustic comfort.
Victorian and Edwardian terraces and mansion flats dominate, with many properties retaining original features. Traffic noise on main roads drives acoustic glazing demand. The active landlord market means many seek EPC improvements.
