State guidance for Missouri
For toilet repair in Missouri, prepare fixture shutoff, floor condition, drain opening, replacement fit, and bathroom access. Confirm the inspected scope, credentials, permits, inspections, exclusions, and restoration responsibility before authorizing work.
Credential verification
Missouri does not issue a single statewide plumbing license; plumbers are licensed and regulated locally by individual cities and counties. State law (Revised Statutes of Missouri, Chapter 341) sets baseline qualifications and, under RSMo 341.010, requires master and journeyman plumbers working in cities or towns of 15,000 or more inhabitants to first obtain a local certificate.
In St. Louis, the City's Board of Examiners of Plumbers and Drainlayers examines and licenses master plumbers, journeyman plumbers, and drainlayers, and St. Louis County runs its own Board of Plumbing Examiners. Kansas City licenses plumbing contractors and tradespeople through its City Planning & Development department, so the right credential to verify depends on where the work is being done.
Permits and inspections
Permit and inspection requirements in Missouri are set locally and vary by city and county. In many jurisdictions a licensed plumber must pull the permit and the work is inspected, while rules for owner-occupied homes differ from place to place. Always confirm requirements with your local building or permitting department before work begins.

Toilet Repair in Missouri: FAQs
How do I prepare for toilet repair in Missouri?
Document whether the issue occurs during filling, flushing, draining, or when other fixtures run and prepare fixture shutoff, floor condition, drain opening, replacement fit, and bathroom access. Ask the professional to confirm the inspected scope, credential, permit responsibility, and exclusions in writing.
Does Missouri guidance diagnose my toilet repair problem?
No. State information helps with credential, permit, and planning questions. The cause, responsibility, and repair or project scope still need to be confirmed for the specific property.
Why does my toilet keep running?
A constantly running toilet is usually caused by a worn flapper, a misadjusted float, or a failing fill valve. These are common and fixable. Our guide on running toilets walks through what to look for.
Is a leaking toilet base serious?
It can be. Water pooling at the base may mean a failing wax ring, and over time that can damage the floor and subfloor. It is worth addressing promptly.
Should I repair or replace my toilet?
Many issues are simple repairs. But if a toilet cracks, clogs constantly, or needs frequent fixes, replacement may be more cost-effective. A professional can help you decide.
