Hardwood sash windows for period homes
We supply and install quality hardwood sash windows across Kingston upon Thames and south-west London. Much of the housing here is Victorian or Edwardian and was built with timber sashes, so we match new windows to the original proportions, glazing bars and profiles.

Conservation areas and listed buildings
Many streets in Kingston, Surbiton, Richmond, Putney and Barnes are in conservation areas. Where permitted development applies, replacement windows should be similar in appearance to the originals. An Article 4 Direction can remove that right, so that a change of window style needs planning permission.
Listed buildings need listed building consent for window replacement. We check the position for your address before ordering.
Richmond alone has 85 conservation areas, Wandsworth 46 and Kingston 26, so it is worth checking before you choose a window.
How sash windows are priced
Sash windows are priced on the number and size of windows, the glazing and the finish. We measure and quote in writing.

Frequently asked questions
Can I replace sash windows in a conservation area?
Often yes, if the new windows look like the originals, but an Article 4 Direction or a listing can mean you need consent. We check your address first.
Can timber sash windows be double glazed?
Usually yes, with slim double-glazed units, depending on the property and any conservation restrictions.
How long do hardwood sash windows last?
Well-made hardwood sashes that are painted and maintained can last for decades. The finish and maintenance matter more than anything else.
What should I send with an enquiry?
The address, photographs of the existing windows and approximate sizes.
