About SASH WINDOW WIZARD
Sash Window Wizard repairs and replaces timber windows and doors, including sash window draught-proofing, double-glazed sash upgrades and bespoke replacements. The small company is based in Chessington and typically works in Surrey, South London and West London.
Owner and managing director Andy Williamson is a qualified carpenter with 25 years’ experience in the timber window and door industry. Replacement windows and doors are spray-painted before fitting; the company says it makes good wall damage and removes waste, and provides a 10-year insurance-backed guarantee with a FENSA certificate.
