License classes in Kentucky
Kentucky 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:
- Apprentice Plumber — works under a licensed plumber while accumulating qualifying experience
- Journeyman Plumber — individual license to perform plumbing work under a master plumber
- Master Plumber — may contract plumbing work and pull permits; must carry general liability insurance on file with DHBC
Experience and training
Journeyman: at least two consecutive years of experience as an apprentice plumber, or completion of a department-approved course plus one year of apprenticeship; applicant must be 18 and a high school graduate or GED holder (815 KAR 20:030). Master: hold a valid journeyman license for at least two years within the past five years plus two years of active employment under a licensed master plumber; alternate paths exist for Kentucky-licensed engineers, for holders of an out-of-state plumbing license held two of the past five years, and for four consecutive years of practice in a state that does not license plumbers.
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 by the DHBC Division of Plumbing. The journeyman examination has both a written portion and a hands-on practical portion (2.5 hours each), with a 75% passing score; the master examination is written, 2.5 hours, with an 80% passing score.
Renewal and continuing education
Annual — licenses expire on the last day of the licensee's birth month. Six hours of approved continuing education taken within the twelve months before renewal are required for both master and journeyman plumbers; no more than 2 of those hours may be safety practices and procedures. The CE requirement is waived for the first renewal if the license was issued within twelve months of that 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
Master plumbers must submit with each renewal a certificate of general liability insurance in an amount not less than $250,000 listing the Department of Housing, Buildings and Construction as the certificate holder (KRS 318.030). Journeyman licenses carry no separate insurance requirement.
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 Kentucky. 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
Kentucky still gives a hands-on practical exam for the journeyman license alongside the written test — 2.5 hours of actual pipe work — which blindsides plumbers relocating from states that test on paper only. The master exam is written but sets a higher 80% cut score than the journeyman's 75%. Renewal is annual and keyed to your birth month rather than a fixed statewide date, so two plumbers in the same shop will have different deadlines; the six CE hours must be earned in the twelve months immediately preceding renewal, and stockpiling old hours will not satisfy it. Master plumbers must file a current $250,000 general liability certificate naming DHBC itself as certificate holder — insurers frequently issue it naming the customer instead, and the renewal is rejected. Kentucky does not publish a reciprocal-state list, but its regulations do provide an endorsement path for people who held an out-of-state license for two of the past five years, and even a path for four consecutive years of practice in a state with no licensing at all.
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.
