Knight’s Mark team specialises in manufacturing and installing wooden windows all across London and surrounding areas including timber windows for conservation areas as well as listed buildings. We supply and fit the highest quality made-to-measure double or triple glazed wooden windows.


All our projects are bespoke therefore you can create a unique style by choosing from different softwood and hardwood types: eucalyptus,  meranti, engineered pine, sapele. And wooden window styles: English sash windows (read more), casement windows (read more), French doors (read more), heritage windows.

Modern technologies allow us to create durable wooden windows with excellent U value rates and at the same time to retain traditional features that can complement your property. Whether you are an individual customer or a developer, rest assured that we will fulfil your needs and will improve the value of your refurbishment or new build project.


High performance timber windows are now significantly easier to maintain compared to when they were originally implemented, able to incorporate such features as double glazing and multi-point locking for optimal security. In addition to their natural, beautiful look, wooden windows have a long service life, are more eco friendly and extremely easy to clean than other materials.

We offer customers insurance backed warranties – as we are CERTASS approved installers, and up to 10 years window warranties.
