London and herts sash windows sash window specialists in restoration draught proofing double glazing

We fully recommend the installation of draught proofing to all our London, Hertfordshire, Essex and Middlesex customers' sash and timber windows to eliminate draughts and reduce noise, while not effecting the traditional look of the windows.


Once installed, draught proofing your sash windows will not only have a dramatic effect on the thermal efficiency of your residence, but your sash window will function with ease, moving smoothly and more jams or rattles! With any restoration or repair job, where sash windows are removed, we thoroughly suggest installing sash window draught proofing at this point, maximising on the window improvements whilst the windows have been removed.


With any restored and refurbished sash windows from London & Herts Sash Windows, draught proofing will be fitted as standard.
