About Keystone
The honest alternative to big-box water treatment.
Keystone Water Company is a family-owned Mid-Michigan business built to give homeowners a straightforward path to better water — without inflated pricing, scare tactics, or all-day sales presentations.
Our Story
Built for Michigan families.
Keystone was founded by Christian Dunn to help Greater Lansing homeowners solve real water problems without the tactics that give the industry a bad name.
We keep our process lean, our consultations remote, and our recommendations tied to your specific home. When a homeowner doesn't actually need a system, we'll tell them so.
Every install is completed by a professional Michigan team, and every quote is written down so it can be reviewed calmly, without pressure.
Family-owned & local
Owned and operated in Michigan. We answer the phone ourselves.
