About us

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. With a highly experienced team at the trade counter helping independent plumbers find solutions for their clients, they quickly achieved this.

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 December 2009 bringing a wealth of expertise with her. 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.

Whilst there is always a keen emphasis on providing that expert “shoulder to lean on” for trade customers, the showrooms have proven to be a great success and are regularly updated and refreshed to showcase the latest products and technology.

As with any business there have been challenges along the way and perhaps one of the greatest was the sad loss of Glenn Moxon who passed away suddenly and unexpectedly in October 2012. Since Glenn's passing in 2012, the team has carried on his legacy by ensuring Watermark Plumbing Supplies offers independent plumbers advice, support, and cost-effective solutions at their trade counters. Glenn’s legacy carries on through his daughter Kate who works with us.

However, the success of Watermark is testament to the original vision and values of Mick, Glenn and John. Those family-orientated values still hold true and are demonstrated day to day by the branch managers and wider team.

Karen Thornton retired from Watermark in December 2021 Karen developed and drove the business forward, we at Watermark wish Karen all the very best for the future.

Watermark has in place a new management team comprising of Del Martyn as the Operations Manager, Liz Steel as the Systems and Compliance Manager and Kate Hustler-Wraight as the Finance Manager. The new management team have over 35 years combined experience within Watermark. The Management Team bring fresh and innovative ideas with Watermark customers and staff at the heart of the decision making process.
