License classes in Louisiana
Louisiana issues the following classes. Getting the class right matters — several states have residential-only or limited-scope licenses that will not cover commercial or multifamily work:
- Registered apprentice — works under direct supervision of a licensed plumber
- Residential Plumber (limited license) — one- and two-family dwelling work only
- Journeyman Plumber — full-scope plumbing under a master plumber
- Master Plumber — may contract, pull permits and supervise
- Gas Fitter — gas piping license by written and manual exam
- Medical Gas Piping Installer — requires approved training course and exam
- Medical Gas and Vacuum Systems Verifier — requires nationally recognized organization exam
- Water Supply Protection Specialist — endorsement added to a journeyman or master license
Experience and training
Residential (limited) license requires 4,000 hours as an unindentured apprentice or 3,000 hours as an indentured apprentice under direct supervision (La. R.S. 37:1368); journeyman apprenticeship hours — verify with the board
One thing worth knowing regardless of state: the hours only count if they were logged properly at the time. Several boards require you to register as an apprentice before the clock starts, and hours worked while unregistered are simply gone. If you are early in the trade, get the registration paperwork right now rather than reconstructing it four years later.
The exam
Board-administered written and manual examination for journeyman and gas fitter; the master plumber exam is a standardized, nationally recognized test
Renewal and continuing education
Annual — all licenses expire December 31; 3.5 hours of continuing professional education required each year before renewal
Letting a license lapse is more expensive than it looks. Some states allow a short grace period with a penalty fee; others treat a lapsed license as forfeited and make you retest from scratch. Put the renewal date in your calendar with a 90-day warning, not a 7-day one.
Insurance and bonding
We could not verify a published state bond or insurance minimum for Louisiana. That does not mean you should work uninsured — local permit offices, general contractors and property managers routinely require a certificate regardless of what the state demands.
Separately from whatever the state requires: Pipe Well requires every plumber on the network to carry current general liability insurance and to upload the certificate before the first appointment is sent.
Working across state lines
Louisiana has reciprocity or endorsement arrangements involving Arkansas, Texas. Reciprocity almost never means "your license is automatically valid here" — in practice it usually waives the trade exam while you still file a full application, pay the fees and meet the insurance and continuing-education rules. Confirm the current terms with the board before you rely on it.
What plumbers actually get wrong here
A master plumber license normally requires a current Louisiana journeyman license, or a Louisiana professional engineer license plus five years of plumbing experience (La. Admin. Code 46:LV-306). Reciprocity is limited; out-of-state licensees who do not qualify may still use their license to sit for the Louisiana journeyman exam — confirm current terms with SPBLA before relying on it.
Once you are licensed: getting the work
A license gets you legal. It does not get you a full schedule. The usual next step is buying leads — $40 to $85 for a contact that three or four other shops bought at the same moment, which at a realistic 10–20% close rate works out to somewhere between $300 and $1,000 for every job you actually book, plus the unpaid hours spent chasing the ones that go nowhere.
Pipe Well works the other way round. We book appointments, not leads, and we handle everything up to the moment you knock on the door: the advertising, the phone call, qualifying the job, getting the address and access details, and agreeing a date and time window with the homeowner. What reaches your phone is a scheduled appointment — name, address, time window and what is wrong. You reply YES and it is yours.
What it costs
Nothing to join. No subscription, no per-lead charge. You do the job, you set your own price, and you collect payment from the customer directly. Then Pipe Well is paid 50% of the job after your documented materials come off the top:
(amount collected − documented materials) × 50%
| Collected | Materials | Net | Pipe Well | You keep |
|---|---|---|---|---|
| $400 | $40 | $360 | $180 | $220 |
| $1,200 | $520 | $680 | $340 | $860 |
| $2,800 | $800 | $2,000 | $1,000 | $1,800 |
| $8,500 | $3,200 | $5,300 | $2,650 | $5,850 |
Due within 48 hours of the customer paying you. If they never pay, you owe nothing. And look honestly at that last row — on a big repipe our share is a large number. If your book is already full of $8,500 jobs you are better off filling that capacity yourself. We are worth most to a shop with open capacity it cannot currently fill.
