About Thomas Weston Sash Windows .

At Thomas Weston Sash Windows, we specialise in the full restoration of original timber sash windows using time honoured techniques and authentic materials to preserve the character of your period home while bringing your windows back to perfect working order.

Based in Cornwall, we work with homeowners across the county, from Truro and Falmouth to Penzance and St Ives. Whether your sashes are stuck, rattling, draughty or suffering from rotten timber, we'll restore them properly no unnecessary replacement, no compromises on quality.

My specialisation: Traditional linseed oil paint
I use authentic, plant based linseed paint for priming and finishing. It penetrates deep into the timber, stays flexible, allows the wood to breathe (preventing rot), resists peeling, and lasts far longer than modern alternatives – often 10+ years with simple maintenance. This gives a classic, subtle sheen perfect for heritage homes, while improving efficiency and reducing noise.
