Replacement timber framed box sash windows for Victorian, Edwardian and Georgian properties.

Church Hill, Replacement Sash Windows

Church Hill, Winchmore Hill

North London Box Sash recently completed the installation of replacement windows at this large Victorian property in Winchmore Hill, North London. 

This Victorian property was fitted with double glazed sashes throughout and draught proofed, using the existing box sash frames. The second floor window was supplied in hardwood for superior durability. The existing frames were stripped back to the original timber and fully refurbished, any inferior timber to the frames was removed, expertly spliced back and resin filled. After the new double glazed sashes were installed, our painting team gave several oil based coats of paint blending the new sashes and box frame as one.


North London Box Sash have changed all the windows in my Victorian property.

Throughout the process i.e. estimate, measuring and commencing the work Mark arrived/started at the agreed times. Mark’s team were professional and took great care with their work, cleaning before leaving each evening. The windows are exact replicas of those removed. I would recommend this company to anyone thinking of replacing their Windows.”
