Sash Masters London Ltd

Sash Masters restores and makes traditional wooden windows in London. Founded in 2021 by classically trained joiner Milan Buček, the company works on sash and casement windows, including those in listed buildings. It aims to restore original frames wherever possible, repairing timber, glazing and moving parts while retaining as much of the existing window as it can.

When a window cannot be repaired, the team makes and installs new wooden frames to order, with choices including single or double glazing and different hardwoods and softwoods. It also makes wooden doors and garden gates. The company uses salvaged or recyclable materials where possible and says new timber is FSC certified. Quotes are provided for proposed work, with the company stating that it does not upsell.
