Company info

London Sash Works Ltd is a family run business based in Middlesex. We provide a full range of restoration and replacement services for all timber sash and casement windows. In addition to timber, we can also offer very high quality and attractive uPVC windows from 'Roseview' and 'Residence 9'

We pride ourselves on having a flexible approach, always trying to find the best overall package to suit each customer's pocket.

Both domestic and commercial contracts undertaken

NEW FOR 2018: In addition to beautiful timber casement windows, we can now supply and install the best uPVC casements on the market from 'Residence 9'

There are many ways we can improve your timber sash windows.....

UPVC sash windows from 'Roseview'
In response to demand from customers, we have now started to install new uPVC sashes from Roseview windows. Complete with wood grain finish they are very close to the originals and are significantly cheaper than hardwood. Links to their website can be found on our website.


UPVC Casement windows from 'Residence 9'
As an alternative to timber, we can now offer customers beautiful  uPVC casements from the 'Residence 9' collection. . Links to their website can be found on our website.

Who will call at my house and who will do the actual work?
Steve Vanstone (the business owner) will call at your home to explain your options and provide you with a quotation. All the on-site work is carried out by Steve's son Adam and our full-time staff including Konrad, Jack, Cameron and Sam.

Conservation area? 
No problem, your new sashes will look exactly the same as the old ones. Including configuration of glazing bars and if necessary the shape of the decorative horns and internal moulding profiles
We can even help you with gaining planning permission from your local authority.

Do we work all year round?
Yes we do. In this country it is just as likely to rain in January as in August! We use plastic sheeting to keep the rain away from the area where we are working.

How much will it cost?
We know that we can deliver a top quality job for a highly competitive price.
Naturally, the price will vary depending on the size and condition of your windows, design features such as glazing bars, arches and the glass specification you choose. 
All costs are 100% agreed after we conduct the survey, no hidden surprises, no last-minute changes, no add-ons.
