Emergency and utility numbers in Missouri
For gas odor, downed power lines, or flooding, call 911 or your utility emergency line first — not a contractor. After the immediate hazard is controlled, hire licensed pros for permanent repair.
- 911 — fire, medical, immediate life safety
- Gas odor — leave the building, do not switch lights, call your gas utility emergency number from outside
- Power outage / lines down — utility emergency line; stay away from downed conductors

No listings here yet
We publish a listing only where the organization asked to be listed, or where every field came from a public licence register. Neither has happened for trade schools in St. Louis yet, so there is nothing to show — rather than a page of names scraped from somewhere and presented as vetted.
The costs, licensing and verification steps below apply regardless. If you run a business here, listing is free and always will be.
Training options in St. Louis
St. Louis is a metro of 281,754 residents, which generally means both union locals and contractor-association programmes operate in the area, alongside community college technical programmes.
Before paying tuition anywhere, apply to the registered apprenticeship programmes in the metro. A registered apprenticeship pays you from the first week and charges no tuition, which makes it strictly better than a paid programme when you can get in. Trade school is the fallback, not the default.

Verify before you hire in Missouri
Check the licence with the Missouri board
Confirm the programme is accredited, and if it presents itself as an apprenticeship, that it is registered with the Department of Labor or the Missouri apprenticeship agency.
Have the insurer send the certificate
Ask for general liability and workers' compensation to be sent to you directly by the insurance agent. A PDF forwarded by the contractor proves the document existed once, not that the policy is current.
Get the scope in writing, with exclusions
What is included matters less than what is excluded. Permits, disposal, patching, and code upgrades triggered by the work are the four line items that most often turn into change orders.
Confirm who pulls the permit
Permit thresholds are municipal in Missouri. The licence holder should pull it. If you are asked to pull it as a homeowner on licensed work, you are absorbing their liability.
Never pay the full amount up front
A deposit for materials on a large job is normal. Paying in full before work begins is not, and several states cap what a contractor may take as a deposit.
