Testimonials

  • Fantastic way to double glaze and maintain character of house. The work was carried out with great efficiency and on time. The lads were a pleasure to have in the house. Immediate elimination of draughts and increase in warmth. Strongly recommend without reservation.
    — Mr Albert, Norwich
  • This company were very reasonable in price compared to other companies that we got a quote from. They were very professional and arrived on time when they said they would, something rare in tradesmen! We were very pleased with the work they did for us and have gone from having rickety windows to ones that are draught free, easy to put up and down but still retaining the character of our lovely old windows.
    — Mrs Matthews, Norwich
  • I am really pleased with the sash windows which were double glazed in my property in Cambridge, and was really impressed with the way you all worked. You were a pleasure to have in my home.
    — Mrs Hemming, Cambridge
  • Thank you Gary for doing the job quickly and tidily.
    — Mr Atkins, King's Lynn
  • 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.
    — Jane Le-Surd, Diss
  • 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.
