Our history

Grab a cuppa, take a seat and settle in to read all about Watermark's History

Having been great friends for many years and with decades of combined experience in both the independent and corporate sector of the plumber’s and builder’s merchant industry, Mick Dodson, Glenn Moxon & John Helliwell opened Watermark in March 2005, in the North Yorkshire market town of Malton.

The vision for the business went beyond the provision of quality products, great service and competitive pricing. Mick, Glenn and John wanted Watermark to be a “hub” for the plumbing industry and a business built on strong family values.

Following the success of Malton, two further branches were opened in quick succession, York in April 2008 and Huddersfield in September 2009.

Karen Thornton joined the team in 2009 sharing the same vision and values as the owners, Karen was soon appointed Managing Director. Over the course of the next few years showrooms were added at each branch in order to attract retail customers and provide a full bathroom design service further enhancing the Watermark brand.

Watermark's journey is truly inspiring, rooted in a vision of not just providing quality products and services but also fostering a sense of community and family within the plumbing industry. Mick, Glenn, and John's dedication to these values laid a solid foundation that has endured even through the challenging loss of Glenn in 2012.

Karen's contribution as Managing Director further propelled Watermark's growth, and her retirement in 2021, marked a transition to a new phase of leadership with Del Martyn, Kate Hustler-Wraight, and Liz Steel stepping up to the plate. Their fresh ideas and commitment to keeping the company centered on its people and customers have undoubtedly played a significant role in maintaining Watermark's success.

While Kate's departure, in 2024, signifies change, it's evident that the ethos established by the founders remains intact. John and Mick are still here, their passion for the company, coupled with the dedication of the entire team, ensures that Watermark is poised for continued growth and success as we approach Watermark's 20th Anniversary.
