What this listing does and does not tell you

TW Colton Plumbing and Excavating Inc. appears on Missouri’s septic licensing records as a registered owts installer, as published August 26, 2026. That is a statement by Missouri DHSS that the licence was held when the record was compiled.

It is not a rating, a review, an endorsement or a guarantee of insurance, price or workmanship — and licences lapse. Nothing on this page comes from the company itself, and no company pays to be here.
