About Us

beforeFounded in 1975 by Clarance and Sue Kersemeier, K-tech Kleening Systems still thrives today as a 2nd-generation family-owned business after more than three decades of serving Central and Northern Wisconsin customers with superior commercial and residential cleaning and restoration solutions. The 100-plus employees that comprise the K-tech team pride themselves on upholding the values of this locally-owned company. An integral part of this value system is giving back to the communities in which it serves. In 2006, the company established K-tech Charities, Inc., a 501(c)(3), to serve as a way to fundraise and provide support to numerous area families and non-profit organizations in an effort to help people in need of a helping hand.

Headquartered in Weston, Wisconsin, K-tech serves customers in Central Wisconsin, throughout the Northwoods communities such as Minocqua, Eagle River, and Rhinelander, and as far east as Door County. Our multiple offices and 45-plus fleet of vehicles provide us with an extensive reach to outlying rural and metropolitan locations.
