  • I am delighted by the work carried out by Sash Window Preservation Ltd. James and the team were professional and courteous at all times, always keeping me up-to-date with how the job was progressing and leaving the house and drive tidy after each day. I am really pleased with the end result, my original sash windows are now double glazed with no alteration in their appearance, and am now looking forward to a draught free winter.

  • Thank you so much for the wonderful job that the sash window team did for us in here in Bedford. All of the team worked so hard and seemed to do a thorough job, very tidy and made the whole process as easy and professional as possible. Thank you all for a wonderful job.
    — Sarah & Simon Blair, Bedford
  • 4 days solid work undertaken to repair and draught proof 7 sash windows, to install one new sash window (with SWP's slim double glazing, which allows for a slim frame in keeping with the original windows), work on sills, and draft proofing 3 outside doors. Ben and Scott were knowledgeable, friendly and tidy, and a pleasure to have around the house (tea and coffee for both: strong, white and 2 sugars). No draughts anymore in the house, smoothly sliding sashes - the kind of workmanship ones hopes for but rarely gets to enjoy. Strongly recommended for anyone who needs work on sash windows undertaken!
