Sash window draught proofing services in the East Counties and Greater London

Based in Norwich, Sash Window Preservation works across a wide area, helping our clients with our sash window draught proofing services.


Sash window draught proofing

Our draught proofing system is a very effective and popular service. By using a brush system, draughts are virtually eliminated whilst the beauty and aesthetics of the sash window remain the same. English Heritage released findings that:


  • Air infiltration can be reduced by as much as 86% by adding draught proofing

  • This results in vast improvements for the thermal efficiency of the window


When choosing our draught proof system, sash cords are renewed, and windows are balanced to ensure perfectly weighted windows. Sash Window Preservation provides our services across the surrounding area for both homeowners and commercial clients. We are CERTASS qualified and a CHAS accredited contractor with a great reputation. To arrange a competitive quotation, just give us a call or send us an email and we’ll get straight back in touch with you.
