Sash Window Restoration and Draught Proofing

One of the most popular services we provide at Sash Restoration London, is the draught proofing and renovation of your original sash and casement windows, to bring them up to modern standards of draught proofing and insulation. The sashes are removed and the whole window is overhauled. The windows are thoroughly inspected for rot and any rotten timbers are carefully cut out and replaced.

A typical sash window refurbishment will involve: 

  • replacing any broken glass

  • replacing any rotten sections

  • re-balancing and re-weighting the windows

  • fully draught proofing the sashes

  • restoring the original boxframe

  • replacing the external pointing

  • replacing all the ironmongery where needed

  • fit new heavy duty pulley wheels

All draught proofing is discreetly run into the windows and does not  alter the appearance of the windows in any way. This service is particularly suited to clients who live in  listed buildings, as planning restrictions will mean that upgrading to double glazing is often not an option.

Draught Proofing Your Sash Windows

If your sash windows are in extremely good order, draught proofing only is an option. This involves the installation of draught proofing into the parting beads and baton rods and running a seal for the mid rail and base of the window.
This is a more economical way of improving the thermal efficiency of your windows, however it is not nearly as comprehensive as a full sash restoration.

This service complies with all new conservation regulations and planning guidelines

The vast majority of sash and casement windows in London are repairable, but should your existing sashes be beyond repair, we can manufacture individual sashes to match the original, as well as offering a complete sash window restoration service.
