Our Story

Local, family-owned Guthrie & Frey Inc. was founded in 1974 and expanded in 1995 to serve Waukesha County in southeastern Wisconsin, as well as Jefferson, Washington and Walworth counties.

Today, the company is split into two vital divisions—the parent company well pumps side and the water filtration and conditioning side, run by son Robert Frey and his wife Susan Frey. Guthrie & Frey Water Conditioning is headquartered in Hartland. Due to company growth, a 2nd full service location in Mequon was recently opened, to offer more complete service and products to customers in Ozaukee County and the north shore area.

Experience

Owner Rob Frey is a Certified Water Specialist Level VI, one of the highest levels of certification in the Waukesha County area. Additionally, all Guthrie & Frey technicians are Contracted Appliance Plumbers, among the most highly qualified trades people working in the plumbing industry. All of our Plumbers take part in compulsory continuing education programs each year. They also adhere to stringent regulations which ensure that customer satisfaction remains a priority.
