Replacement Sash Windows
Have your windows reached the end of their lifetime?
Are they rotten, broken, or beyond repair?
Would you like to relax and enjoy the benefits of new windows?
The London Sash Window Company installs brand new bespoke sash or casement windows to order. As well as sash window replacement too.
All windows are made to measure using traditional joinery methods, yet fitted with modern requirements and meet current building regulations.
Using quality materials whether hardwood or treated softwood we provide new windows that reflect the character and look of your original windows, yet are double glazed and fully draught-proofed.
We pay particular attention to all detailing, such as glazing bars and moulding, to ensure your new windows are fully in keeping with your property. Our expert craftsmen have extensive experience working with windows in listed building or conservation areas, so you can be sure we treat your property with the respect it deserves.
All new windows are pre-painted in our own workshop, to ensure the very best finish without the need to involve other tradespeople.

Certified & Guaranteed
Giving you peace of mind
Since 2002 replacement windows are governed by strict building regulations. We will ensure that all relevant building regulations are met. Once an installation is complete clients are provided with a FENSA certificate to confirm the regulations have been met. Should you decide to sell your property confirmation that building regulations have been meet will be required by your solicitor in the form of a FENSA certificate.
All replacement windows are fully guaranteed. This is our own guarantee, which is then further endorsed by a Lloyds of London insurance backed guarantee.
