Expert timber sash window restoration for period homes, listed buildings and conservation areas across Cornwall

Crowd of people walking down a lively street decorated with colorful flags hanging overhead. Shops with storefronts and buildings with different styles line both sides of the street under a clear blue sky.

Cornwall is home to some of Britain’s finest period architecture : Victorian terraces, Edwardian villas, Georgian townhouses and traditional Cornish cottages, many with original timber sash windows that deserve to be preserved, not replaced.

Thomas Weston Sash Windows is relocating to Cornwall in Summer 2026, bringing years of specialist expertise in traditional sash window restoration. We use time honoured techniques and authentic materials, including traditional linseed oil paint to restore your windows to full working order while preserving every detail of their original character.

Whether your sashes are painted shut , rattling in the frame, or suffering from decades of paint build up and rotten timber, we’ll bring them back to life without the unnecessary cost and heritage loss of replacement.

 

WHY CORNWALL HOMEOWNERS CHOOSE RESTORATION OVER REPLACEMENT 

•       Listed buildings and conservation areas often legally require like for like restoration

•       Original timber sash windows, properly maintained, can last another 100+ years

•       Retain the authentic character and kerb appeal of your period home
