Welcome to
John Knight Glass

We have been manufacturing and installing quality Steel, Alu-clad, Aluminium, Timber, Timber Alternative and UPVC windows, doors and roof lights as well as designing and installing all glass structural glazing throughout the North West since 1984. Our Heswall showroom contains a wide selection of our product ranges for you to browse through and try out. In our showroom we display examples of our bespoke premium products as well as our cost effective but still excellent quality budget ranges. Our showroom is considered one of the most extensive window and door showrooms in the UK so a visit is highly recommended for both inspiration and our expert advice.

Builder, Architect or Homeowner?

We offer a full in house design and project management service that runs from initial enquiry through to final installation. Our team will work closely with you throughout every stage of the journey from design, survey and procurement, to site preparation, installation and aftercare. This front to back approach allows projects to be completed efficiently and to the highest of standards. If preferred we can work directly with your Architect or Builder to execute the project whilst always keeping you informed and carrying out your wishes. This bespoke service and our extensive product range enable us to provide a one-stop-shop to meet all your needs.

Through our national and international partnerships with companies such as Crittall, Internorm, Rationel, Velfac, Solarlux, Evolution, Centor Europe and PanoramAH, we can offer the best available products for any home or businesses throughout the North West of England, the wider UK and now the Isle Of Man.
