Why choose us?

The Sash Window Workshop

The Sash Window Workshop was founded in 1994 by our Managing Director, Richard Dollar.  We manufacture, install and repair timber windows and doors across London and the South.  We are proud to be members of Made in Britain, with all our replacement windows and doors are made by us in our Berkshire workshops.

We believe that windows and doors are an important feature in any home and that they must not only be as energy efficient as possible, but also be in keeping with the architectural style of the building.  Our goal is to ensure that they enhance both the look and value of your property. With that in mind, we offer a bespoke service tailored to your needs.

We recognise that windows and doors must be installed efficiently with both consideration and the minimum of disruption.  We are proud to be able to offer our customers, over 20 years knowledge and experience in the timber window and door industry, combined with excellence in the delivery of both products and service.

One Stop Shop Windows and Doors

One Stop Shop

Operating from one central location in Berkshire we are able to ensure a consistently high standard of work.

Providing an installation service, alongside the manufacturing of your new windows and doors, means we can provide a one stop shop for replacing your timber windows and doors.  View our replacement services.

We also provide a repair and draught proofing service if your windows and doors do not require replacement.  View our refurbishment services.

Customer Service

Whether you are looking to draught seal a couple of windows in your home, or working on a large project to replace multiple windows and doors, we recognise the importance of providing excellent customer service, and tailor made solutions to suit your requirements.

We have worked on a wide range of properties, from small flats to prestigious projects, such as our work for the Oxford Wildlife Trust and The Admiralty Buildings.

Customer service is very important to us. We value and rely on customer recommendations for much of our new business. As such, we pride ourselves in offering all our customers professional, friendly advice on replacing or restoring their timber windows and doors.

We understand that your requirements are unique and have set ourselves service standards to ensure that we meet your precise needs. Our aim is to ensure that you will want to recommend us to others!

We are very proud to be Which? Trusted Traders and to have a 5 star Trustpilot rating.
