We repair and restore sash windows across Whitstable, Tankerton and Herne Bay. Salt air, driving rain and small original sashes make this very particular work — a lot of what we do here is careful splicing and re-glazing rather than anything wholesale. Draught-proofing £280 + VAT, cords £250 + VAT, full restoration £1,280 + VAT.

Period windows in Whitstable

Whitstable’s cottages were never built for the weather they get. Small sashes in thin softwood sections, often with original crown glass, sitting in walls that take rain off the sea. We repair the sections that have gone, keep the glass, and draught-proof the sash so the wind stops getting past it — which in a cottage makes a bigger difference than any glazing upgrade.

  • Small-section cottage sashes repaired, not replaced
  • Original glass retained and re-puttied
  • Weatherboard and render details made good around the frame
  • Herne Bay Victorian seafront terraces with tall sashes
  • Island Wall and Whitstable conservation-area properties

Frequently asked questions

Will draught-proofing spoil the look of an old cottage window?

No. The seals are routed into the sash and the beads, so there is nothing to see from inside or out. It also stops the rattle.

Can you keep my old glass?

Yes, and we would push you to. Old cylinder and crown glass cannot be bought back once it is gone.

Do you cover Tankerton and Seasalter?

Yes, and Herne Bay, Chestfield and Swalecliffe. No travel charge.
