Questions

Frequently asked questions

How are winners chosen?

Winners are chosen by our editorial team using five criteria: local ownership, response time, included testing, transparent pricing, and service-area fit. A category is only awarded when a clear winner emerges under those criteria. The full process is published on our methodology page.

Who won Best Overall for 2026?

Jones Air & Water took Best Overall for 2026. The company is family-owned, has operated since 1995, is owner-operated, includes free in-home water testing, and serves St. Charles, Lincoln, Warren, Franklin, and Jefferson counties plus the St. Louis metro.

Is Best Water Companies STL affiliated with the companies it features?

This site features sponsored placements and may be compensated when you request a quote. Awards reflect our editorial criteria, and every company named on this site is described factually and neutrally.

Do St. Louis area homes really need water treatment?

Many homes in the greater St. Louis region deal with hard water, and homes on private wells in outlying counties can face additional water quality concerns. A professional water test is the only reliable way to know what is in your water, which is why included testing is one of our award criteria.
