    Sash Window Draft Proofing & Installation of New Sash Cords

    Posted 03 February

    I had sash window draft proofing done at very short notice just before Christmas. Jason also installed new sash cords. He is professional, cleans up after himself and good at his job. I am a repeat customer. I used him 10 years ago to do some sash window refurb. He gives advice, is easy to speak to and polite.

    Insulating and repairing our sash windows and doors

    Posted 05 December 2024

    Jason insulated all our windows and doors and repaired three of the Sash windows which he identified as being rotten. He also put locks on all the windows. He did this quickly and efficiently and tidied up after himself. He explained what he was doing as he went along and was always cheerful and punctual.

    Window Refurb + Draft Proofing - Top-notch service and expertise – highly recommend!

    Posted 20 October 2024

    Jason did a great job refurbishing and draught-proofing all the windows in my new house (sash, casements, and French doors). He also put in new sash cords and fixed up a few things like a rotten wood sill and a new casement window. The work was really professional, and the price was very reasonable. Communication was always clear, and he clearly knows his stuff. No mess left behind either—they cleaned up every day. Jason’s not only great at what he does but is also a nice guy who gave me some good tips for other parts of my refurb. Highly recommended, and I'll definitely be using him again for

    Jason has done a few different jobs for me on some very tall windows and on a full sash repair. Always does a professional job for a fair price and problem solves as he goes along. Highly recommended.

    Bedroom window frame with door and windows.

    Posted 19 June 2024

    We had a damp ridden window frame the windows were black from water seeping through the gaps and the door to the balcony was so rotten we didn’t want to open it, we needed new windows and a door and it was replaced with a service I have never received before, the courtesy and respect for my property was exemplary, No mess they left the room clean and tidy every evening.They had to remove the whole frame and I live on the fourth floor with no lift!! the whole thing is beautiful looking and I cannot wait to show my friends such quality work. Thank you so much Dr Sash.

    Refurbishment of double glazed wooden sash windows.

    Posted 01 May 2024

    Jason was prompt He clearly knew what he was doing, and kept me informed as to what he found and actions he took to fix any issues. Before he left he made sure I could open all the windows and is a whiz with the hoover. I've asked him to come back to do the same refurbishment to the lounge windows.

Based in London, we are the sash window refurbishment and draught proofing specialists.

Lower your heating bills with our draught proof sealing system, guaranteed to stop all draughts and rattles.

Speak to us today for a test window.


Our services include the following:

  • Sliding wooden sash windows
  • Draught proofing
  • Sash cords repair
  • Relieving jammed sashes
  • Treatment to decaying timber
  • Full renovation service
  • Security locks and stops

Sash Doctor uses a method for reducing draughts with discretely positioned seals that conserve energy and improve thermal comfort.

Many timber windows are inherently draughty. With gaps of 3mm and more around the edge, they typically account for 20% of the heat loss from your home.


Our sealing system will usually reduce this heat loss by about 80%. It will also reduce noise transmission, dust penetration and eliminate rattles during windy weather.

While you may wish to retain the weathered fixtures of your windows, a complete range of quality brass locks, stops and fasteners are available.
