License classes in Michigan
Michigan 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:
- Plumbing Apprentice — registration (not a license), must be renewed annually
- Journey Plumber — licensed to perform plumbing work
- Master Plumber — qualifies a plumbing business and supervises journeys and apprentices
- Plumbing Contractor — business license that requires a qualifying master plumber
Experience and training
Journey: at least 6,000 hours of documented experience gained over not less than three years as a registered apprentice plumber. Master: 4,000 hours as a licensed journey plumber over not less than two years immediately preceding application.
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
State-administered through LARA's Bureau of Construction Codes (journey plumber examination includes a practical component)
Renewal and continuing education
Apprentice registrations and journey plumber licenses renew annually by April 30; master plumber licenses renew every three years by April 30 (renewal opens 90 days before expiration). No fixed annual CE hours — licensees must complete a code update course within one year of a new code adoption
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 Michigan. 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
We could not confirm any published reciprocity agreement for Michigan. That does not always mean there is none — several states evaluate out-of-state licenses case by case, or let you sit for the exam on the strength of a license held elsewhere. If you are relocating, call the board and ask specifically about endorsement or credential review rather than assuming you start over.
What plumbers actually get wrong here
Anyone performing plumbing work must register as an apprentice with LARA within 30 days of employment, and any hours worked while that registration is lapsed or expired do NOT count toward the 6,000 hours for journey licensure — this is the single most common way Michigan applicants lose credit. A business cannot hold a plumbing contractor license unless a qualifying individual holds a LARA master plumber license.
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.
