Testimonials

  • Gary and the others were extremely reliable. The job was finished within 2 days (a day quicker than quoted) working late hours to double glaze the windows to my property in Cambridge. When they had to come back for a little adjustment they organised it within hours. We are very pleased with the outcome both in terms of insulation and looks. I would recommend Sash Window Preservation without hesitation.

  • 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!

  • Very impressed with the service from Sash Window Preservation. Staff dealing with the quote were very helpful and professional nothing was too much trouble even when I changed the requirements. The work was completed on time to a very good standard and the refurbished sash windows have really improved the overall appearance of my Cambridge house. The windows are no longer draughty and the house is quieter - now looking forward to cheaper heating bills

  • I was very happy with Darren and Jesse who completed the work. They were tidy, polite and careful workmen.
    — Mim Ramsby, Norwich
  • A feat of pefectionism. These guys achieved a near miracle to restore my seven sash windows with such expertise that they now look magnificent. This was no easy job. The boxes had moved and distorted in every conceivable direction. SWP stuck at it until all windows were free-running and perfectly balanced. Far better to repair than replace, but far harder. Achieved because SWP really care about the locality. The cost was super-competitive for the work done. I could not be happier with the end result. Thank you SWP.
