Our History

Refined & Pure. That's Sterling Quality.

Our Company

In a day and age when face-to-face expertise is hard to come by, Sterling Quality Water, LLC, takes pride in providing a personal and professional water treatment service. Sterling Quality Water was founded in 1992 by Charles Sterling in Westminster, MD, on the belief that our business should be conducted on a personal and professional level, and provide an honest, expert, and specialized experience for our customers. We are a family-run business and we value that our employees and customers be treated as a part of the Sterling family.

For over forty years, I have been working in the water treatment industry. I started shortly after completing my service in Vietnam in the US Navy working for an international water treatment sales company on the west coast. After meeting my wife and moving to the east coast to raise a family, I put my experience in the industry serving in the US Army Reveres with a water treatment unit. As my employer’s sales philosophy changed, I left the corporation to start my own treatment company, Sterling Quality Water, in 1992. During this time, I also served on mission teams through the United Methodist Church to provide water treatment in Central America.

In 1993, we opened our first store on Main Street in Westminster, and throughout the years we have shrived to provide the best method of water treatment to meet individual needs with quality products. In 2008, Sterling Quality Water expanded and reorganized into an LLC to include its second generation of Sterlings. Now celebrating our 25th year! We are proud to be back on Main Street with the downtown community. Stop in and visit with us and bring a water sample for a free water test.

We are an independent water treatment company, which gives us the ability to offer a wide variety of personalized treatment solutions, and over the years we have improved our product lines by offering lifetime factory warranty stainless steel tanks, which are Made in the USA and manufactured in Mechanicsburg, PA. Our equipment lines are internationally recognized brands and industry-standard. We serve thousands of homeowners and businesses throughout Maryland and South Central Pennsylvania who have taken advantage of our products and services.
