Double glazing services you can rely on
Sash Window Preservation is an established company based in Norwich. We have an excellent reputation, providing a wide range of services across Greater London and the eastern counties. We specialise in double glazing, draught proofing and bespoke sash window repair, working with both domestic and residential clients alike.
You can be confident choosing us, we have an exceptional team of staff and are CERTASS qualified and an accredited CHAS contractor. In almost all cases our windows are manufactured locally using local suppliers. If you would like to arrange a free onsite or video quotation, just get in touch with us and we will be happy to help.
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.
