Duration Windows celebrates 40 years of innovation and excellence

This year marks a major milestone for Duration Windows as the company proudly celebrates its 40th anniversary. Founded in 1985 by Brian Chelton and Dennis Mitchell, the business began with a single product—Secondary Glazing. Four decades later, that very product remains a customer favourite, reflecting the timeless quality and innovation at the heart of the company.

From these humble beginnings, Duration Windows has grown into one of the UK’s largest manufacturers of premium aluminium windows, doors, and roofs. A trusted, family-run business, it has earned a stellar reputation for its commitment to quality, cutting-edge design, and exceptional service. Whether for trade professionals or homeowners, Duration offers a true one-stop shop: one supplier, one delivery, one payment – a seamless customer experience from quote to delivery.

Today, the company operates from an expansive 60,000 ft² estate, comprising 18 factory units, a central head office, and a state-of-the-art showroom showcasing its latest innovations. Every product is custom-made in-house by skilled staff using advanced machinery. This in-house control ensures consistent quality, rapid lead times and all products come with a 10-year guarantee.

Speaking on the occasion, Managing Director Grant Chelton shared his pride in the company’s journey: “Reaching 40 years is a fantastic milestone. It’s all down to our loyal customers and our brilliant, dedicated team who continue to deliver high-quality products year after year.” He added that the whole family is thrilled and looks forward to marking this special occasion with those who made it possible at the launch of our brand new showroom. 

As Duration Windows celebrates this remarkable anniversary, it stands as a testament to the power of family values, relentless innovation, and unwavering dedication to quality. Here’s to 40 years of excellence—and many more to come.
