About Us

Jon Chambers Windows has been established since 2013. Since then we have gone from strength to strength with the help of our loyal and valuable customers. We have expanded from 1,500 square feet to an all-purpose 3.5-acre site which now includes a Showroom and a Conservatory Show park which is being expanded this year to include a Garden room Guardian Solid Roof Conservatory, an Orangery, a Glass Roofed Conservatory and a Polycarbonate Roofed Conservatory.

Jon (right) and Paul (left) have been in the industry for many years and have many customers who have moved houses once, or even twice, who have always come back to us for their replacement windows etc., as they know we are honest and trustworthy.

We cover 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 with our main focus on customer satisfaction. All our Senior Installers and Surveyors have passed the MTC (a qualification in the window installation industry). We are proud members of Checkatrade, Certass Fenestration, and Quality Assured National Warranties offering a 10-year insurance-backed guarantee and are also approved by Team Guardian Solid Roof installers.
