Period windows in Dartford

A lot of Dartford’s period housing sits within earshot of the A2, the A282 or the railway. Most of the noise coming through an old sash window is not through the glass at all — it is through the gaps around the sashes and the meeting rail. Sealing those properly is cheap, quick and makes an immediate difference, and it is worth doing before anyone sells you new glass.

  • Concealed draught-proofing that cuts rattle and road noise — £280 + VAT
  • Secondary glazing for the worst-affected rooms
  • Slim double glazing at £980 + VAT where the sash allows it
  • Cords, weights and balance put right — £250 + VAT
  • Rotten rails and sills spliced in new timber — from £80 + VAT

Frequently asked questions

What is the cheapest way to make my windows quieter?

Draught-proofing, every time. It is £280 + VAT per window and it deals with the gaps, which is where most of the noise gets in.

Does secondary glazing work for traffic noise?

It is the most effective option on a sash window, because the wide air gap between the original glass and the inner pane is what blocks sound.

Do you cover Bexley and Sidcup?

Yes, along with Crayford, Swanscombe and Greenhithe. No travel charge.
