What Guthrie & Frey Water Conditioning does
Guthrie & Frey Water Conditioning is a family-owned water treatment company headquartered in Hartland, Wisconsin, founded in 1974. The firm designs, sells, installs, and services water conditioning and filtration systems for residential and commercial customers across Southeastern Wisconsin, operating three branch offices (Hartland, Mequon, Wales) and a direct field-service technician workforce. Its core product portfolio centers on ion-exchange water softeners (proprietary GF Series, GF Twin Alternating Series, and the H-125 through H-300 commercial line sourced from manufacturer Hellenbrand), chemical-free iron and manganese filtration (ProMate 6.0 / Iron Curtain, Iron Curtain Junior), NSF/ANSI Standard 58-certified reverse osmosis drinking-water systems with specialized arsenic and PFAS modules, and the ION Cooler point-of-use filtered-water dispenser. Underlying technology is conventional water-treatment engineering — ion exchange resin regeneration, multi-stage membrane filtration, oxidation-based iron removal, and VFD constant-pressure well-pump systems — with proprietary configurations around metered demand, salt efficiency, and tank construction rather than novel chemistry.
The business operates multiple complementary revenue streams. Recurring revenue comes from a rent-to-own equipment program with one-year interest-free terms and rate-locked monthly payments (rates guaranteed never to increase), automatic salt delivery (solar salt crystals at $14.75/40 lb, rust-inhibiting pellets at $16.45/40 lb) with doorstep placement and visual inspection, and ongoing service/maintenance contracts. One-time revenue comes from direct equipment sales (with free installation on replacements), well pump and pressure tank installation/repair, state-licensed well inspections and chlorination, and on-site plus laboratory water testing (free for hardness/iron/TDS/pH; paid for PFAS, lead, bacteria, nitrates). Customers engage via a website with content-marketing blog, 24/7 phone sales, SMS/email consent-based follow-up, and walk-in service at branch offices; lead generation centers on a free no-obligation water analysis. The company reports no external funding, no institutional investors, and no PE/VC involvement — ownership is concentrated in the founding Frey family, with Robert (Rob) Frey holding Certified Water Specialist Level VI and co-running the water-conditioning LLC with his wife Susan Frey separately from the parent company's well-pumps division.
