How much does sash window draught proofing cost in London?
Silver Saints draught proofing is fixed price and starts with a £35 plus VAT survey and quote visit, after which a firm written quote is given for the windows, with frayed sash cords optionally renewed at £25 plus VAT per cord.
How long does it take to draught proof a sash window?
A standard sized sash window takes about two hours to draught proof, covering the meeting rail, the parting beads and seals to the top and bottom of the sashes.
Will draught proofing stop my sash window rattling?
Yes, draught proofing stops the rattle caused by poorly fitted sashes because the brush pile and compressible seals close the gaps the sashes move in, and it also improves noise resistance.
What does the draught proofing process involve?
Silver Saints removes the lower sash and routes a groove into the meeting rail for a brush pile and carrier, replaces the parting beads with new beads containing an integral brush pile, adds compressible seals to the top and bottom sashes, reassembles the window and makes good any decoration disturbed.
Can you draught proof sash windows in a conservation area or listed building?
Draught proofing keeps the original sash windows and adds discreet seals rather than replacing the windows, which is usually the preferred approach in London conservation areas and listed buildings, though formal consent should always be confirmed with the local authority for listed properties.
Do you also replace the sash cords?
Silver Saints renews frayed sash cords during draught proofing at £25 plus VAT per cord, and for cords that have already snapped the dedicated sash cord replacement service can be booked instead.

Our Process
The draught proofing process

- Replace parting beads with new parting beads containing brush pile
- Add compressible seals to the top of the top sash and bottom of the lower sash

The draught proofing process:
- The lower sash is removed from the frame. A groove is routed into the meeting rail (where the two sashes meet in the closed position) a brush pile and carrier is fitted into the groove.

- A hard wearing compressible seal is added to the top of the top sash and to the bottom of the lower sash.
- The window is then reassembled. Any disturbance we have made to the decoration is made good.
- The end result is a sash window draught proofed around it's perimeters, rattles are eliminated and noise resistance is improved.
- If sash cords are a bit frayed, replacing them while draught proofing is a good idea. Add £25+vat per cord.
