  • Your chaps were cheerful, upbeat and quick, they turned up when they said they would and were quick and efficient and did a good tidy job. House was left locked up and clean. Messages were communicated and were pleasant and polite at all times. And one more thing I slept till 10:30am on Saturday morning.....no noise!

  • We were actually considering replacing our sash windows when we met with Gary to discuss renovation. They were able to offer exactly what we wanted - replacing the glass in the sash frames with double glazed units. The wood and sills were repaired and the windows really do look and work great again. We are so glad we decided to keep them. Gary and his team were really helpful and informative and got the work done very quickly. Thanks!
    — Mrs Saunders, Cottenham, Cambridgeshire
  • We are extremely happy with the work carried out by Sash Window Preservation, from the initial quote to the restoration work and the draft proofing. All work was done to an extremely high standard and special attention was paid to our original stained glass windows. The staff we dealt with in the office and when carrying out the works were very helpful. I would definitely recommend Sash Window Preservation and am very happy with the work carried out, and looking forward to a warmer winter!
