If your sash windows, frames or sills are in need of some TLC, we can offer varying techniques to solve common problems such as minor or major rot, cord renewal and window rebalancing.
At Sash Window Preservation we are market leaders in double glazing existing frames. How? By creating a deeper rebate in the original frame this allows us to fit in a slim double glazed unit.
Our special draught excluder is fitted in the meeting rail along with the staff and parting beads. This leads to vast improvements to the thermal performance of the window and heat retention.
We have restored, repaired and renovated many sash windows belonging to schools, halls, estates and other commercial buildings. Just take a look at some of our successes.
“ 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 ”— Mr Round, King's Lynn
“ 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! ”— Amy Horton, Norwich

“ 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
