Our History

Established in July 1993 by Andy Wells and three partners, Sterling began in a small unit on Winwick Quay. Over the years, our success led to expansions across several units on the Winwick Estate.

In 2005, we moved to a larger unit in Woolston on Chesford Grange, and in 2009, we fully transitioned to Chesford Grange, now operating from three spacious units where we manufacture PVCu, composite, and aluminum products.

With 30 years of experience, Sterling proudly serves trade customers and the public in the North West, Yorkshire, North Wales, and the Midlands. We value our local team and continue to prioritise exceptional quality and customer satisfaction.
