Period windows in Margate

Thanet has some of the finest Regency window joinery in the South East, and some of the most neglected. Dalby Square, Hawley Square and the Old Town are full of sashes that have been painted shut, had the cords cut, or had the lower rails patched with filler that has since let water in behind it. Almost all of it is repairable, and on a listed building repair is what consent is given for.

  • Regency and Georgian squares, much of it listed
  • Cliftonville terraces converted to flats, with sashes long since jammed
  • Old Town cottages with small-pane sashes and original glass
  • Filler repairs cut out and replaced properly in timber
  • Draught-proofing for houses exposed on three sides

Frequently asked questions

The windows in my flat are jammed shut — is that a cords job?

Usually it is cords plus paint. We free the sash, re-cord it, re-balance it and draught-proof it in the same visit. That is £250 + VAT for the cords and £280 + VAT for draught-proofing per window.

My building is listed. What can be done without consent?

Repair and like-for-like restoration normally needs no consent; glazing changes and replacement do. We can supply the specification for an application.

Do you cover Broadstairs and Ramsgate?

Yes, and Westgate, Birchington and the villages. No travel charge.
