About Kaempf & Harris

Since 1937, the Warner name has been synonymous with value, quality, and integrity. With Matt Warner becoming CEO in 1998, our company reached a rare accomplishment—its third generation of family ownership. Over the decades, R.W. Warner has expanded into a family of service divisions that include Warner Service, Warner Construction, Kaempf & Harris, and Warner Mechanical. Our unwavering commitment to customer satisfaction has allowed our enterprise to continually grow for over 88 years.

For more than 70 years, Kaempf & Harris has provided exceptional craftsmanship and service to the area’s most respected and well-known mechanical companies, general contractors, corporations and institutions. We fabricate more than 500 tons of metal every year, including aluminum, custom stainless steel, galvanized steel and black iron steel. We deliver precise, high-quality products from smaller, custom design solutions to the most complex design-build and spec industrial, commercial and institutional sheet metal projects.
