Testimonials

  • We were delighted to find a company in Norwich who could double glaze our existing windows. When Sash Window Preservation came to do the work we found them to be diligent in their approach to the problem. When finished we found the work had been carried out with great efficiency and time was taken to get everything right. We fully recommend any household that is looking for an alternative to new wooden double glazed windows

  • We're very pleased with the work and the house is considerably less draughty and the slimlite glass looks amazing. Thanks again to the team!
    — Mr & Mrs King, Essex
  • 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!

    — Paul and Michelle Mersh, Colchester
  • Very good service with polite and efficient staff. I had my front sash window done which has shutters and it looks superb and doesn't rattle anymore! I wish I'd known about this company last year when I had all the other windows replaced with UPVC...the only reason they couldn't replace the front window was because of the shutters. The cost was the same.
