Colgate is an unincorporated community in the southeastern corner of Washington County, within the Village of Richfield near the Waukesha County line. It’s known for rolling, wooded terrain and single-family homes on larger lots, with Highway 164 providing access to Menomonee Falls and the rest of the metro area.
Many Colgate homes use private wells and septic systems. The Colgate mailing address is also used by some homes in neighboring municipalities, so it’s worth confirming which village or town a property is actually in for taxes and services.
