We provide integrated solutions across cleaning and sanitation, water and wastewater treatment, agriculture, and bulk chemical delivery. Our programs combine specialty chemistry, application equipment, and on-site technical service to help customers operate more consistently and reliably.

Rather than offering one-size-fits-all products, we design solutions around how each facility actually runs—its equipment, processes, people, and regulatory requirements.

We do this by pairing innovative chemistry with practical field expertise, strong service programs, and a deep understanding of our customers’ operations.

Founded in 1968 by Wes and Marie Funston, Wesmar was built on the belief that chemical programs work best when they are supported by knowledgeable people and responsive service. Over the years, we have grown by partnering closely with customers, listening to their challenges, and developing solutions that work in real-world conditions.

Today, Wesmar serves a wide range of food, industrial, water, and agriculture customers while maintaining a hands-on, service-driven approach that has defined the company from the beginning.
