Sash Window Restoration in Bristol, Bath & the South West
Original timber sash windows are among the finest features of any Georgian, Victorian or Edwardian home, yet decades of weather and wear leave many rattling, draughty and sticking. Professional sash window restoration returns them to smooth, quiet, weathertight operation while preserving the character and joinery that give a period property its value. At Avon Sash Window Specialists we restore, repair and draught-proof timber sash windows for homeowners, landlords, architects and heritage bodies across Bristol, Bath and the wider South West.
A typical restoration begins with a free, no-obligation survey to assess each sash, its cords, weights, pulleys and timber. Where decay has set in we carefully splice in new hardwood or Accoya rather than replacing the whole frame, retaining as much original material as possible. Broken sash cords are replaced, weights rebalanced and pulleys serviced so the sashes glide as they were designed to. We then route discreet brush-pile seals into the parting and staff beads — virtually invisible once fitted — which can cut draughts by up to 90%.
For owners seeking warmth and acoustic improvement without sacrificing period detail, we bond authentic slimline double-glazed units into existing sash frames. The result is modern thermal performance behind traditional glazing bars, and because the units sit within the original joinery, the appearance of your windows is preserved. We also work regularly on listed buildings and within conservation areas, sourcing reclaimed and mouth-blown cylinder glass and supporting listed building consent applications where required.
Every restoration is surveyed, priced and delivered by our own small team of time-served, fully insured joiners from our Bristol workshop. There are no subcontractors and no surprises — just a fixed written quotation before any work begins.
