Who We Are

Jon Chambers Windows has been established since 2013 and has since gone from strength to strength with the help of our loyal and valuable customers. We have expanded from a small 1,500 square foot facility to a purpose-built 3.5-acre site, featuring a showroom and a conservatory show park. Our showroom is being expanded this year to include a garden room, a solid roof conservatory, an orangery, a glass-roofed conservatory, and a polycarbonate-roofed conservatory.

Our Services

At Jon Chambers Windows, we pride ourselves on providing a wide range of services, including the installation of windows, doors, conservatories, garden rooms, orangeries, and solid roof conservatories. We cater to a 50-mile radius from our premises in Kings Lynn, which is situated on the borders of Cambridgeshire, Norfolk, and Lincolnshire. Our prices are highly competitive, and our main focus is on customer satisfaction.

Our Team

The company is led by Managing Director Jon Chambers, Sales Director Paul Clarke, and Finance Director Lynne Chambers. All three are ably assisted by Sonia Clarke, Paul's sister, who serves as our receptionist. With over 70 years of combined experience in the window industry, Jon and Paul have built a reputation for honesty and trustworthiness.

We install windows, doors, conservatories, and garden rooms from the advanced Liniar range profile, which has an A+ thermal rating. Our prices range to suit all requirements, allowing homeowners to choose the perfect product for their needs and budget.
