Bespoke Timber
Sash Windows Restoration, Draught-Proofing & Installation across South London.

Many original sash windows are condemned unnecessarily when they can be saved through precise joinery. Our restoration process addresses the key wear points of traditional box frames. We carefully remove the sashes, scrape back old paint layers, and inspect the sash stiles and meeting rails. Where decay is present in the lower box or sill, we perform durable timber sill splice repairs using seasoned hardwood or Accoya, bonding them with advanced epoxy resin. To restore the effortless glide of your windows, we replace snapped cords with heavy-duty wax-impregnated cotton sash cords, service the pulley stiles, and calibrate the internal lead or iron counterweights to ensure perfect balance. This meticulous care ensures a smooth operation that lasts for decades.

Old sliding sashes are notoriously prone to rattles and cold drafts. Our draught exclusion system is completely hidden from view, preserving the authentic visual profile of your windows. We machine precise grooves directly into the new timber parting beads and staff beads, installing high-performance brush seals that seal the gaps around meeting rails and sash stiles. This system prevents cold air ingress and eliminates rattles entirely. Homeowners in busy South West London areas, such as those near the South Circular or Battersea Park Road, will also notice a significant reduction in street noise, turning draughty period rooms into quiet, energy-efficient spaces.

Maintaining the strict aesthetic demands of historic districts requires specialised glazing solutions. Our bespoke timber sashes integrate A-rated double-glazed units, which utilise low-emissivity (low-E) glass, argon gas filling, and warm-edge perimeter spacers. At just 11mm to 14mm thickness, these ultra-slim units replicate the elegant, narrow sightlines of original single-glazed panes and are finished with traditional putty lines. This makes them highly acceptable to conservation planning officers across Wandsworth, Lambeth, Richmond, and Merton, allowing you to enjoy modern thermal insulation without sacrificing the heritage value of your home.

If your property is subject to Article 4 Directions, such as those on the Shaftesbury Park Estate in Battersea or Albert Square in Lambeth, window alterations require careful compliance. Like-for-like timber repairs do not typically require planning permission, but replacing entire windows usually does. Charlie Burgess provides experienced advice on local authority guidelines. As a FENSA-registered business, we ensure all complete replacements are fully compliant with current building regulations. We back all new timber window installations with a comprehensive 10-year guarantee, supported by £2m public liability insurance for absolute peace of mind during the project.
