Plumbing License West Virginia: The Two Cards Every Plumber Needs (2026)

West Virginia is one of the few states where a plumber and the plumbing company that employs him need two completely separate credentials from two completely separate authorities, and where holding one of them gives you exactly zero right to do what the other one covers. Miss that and you can be fully licensed, fully insured, on a job you are not legally allowed to be on.

Here is how the state actually works, straight from the West Virginia Division of Labor and Chapter 21, Article 14 of the West Virginia Code.

The two-layer system nobody explains up front

Layer one is the plumber certification. It is issued to a person by the Commissioner of Labor at the WV Division of Labor. Every single individual who performs plumbing work in West Virginia has to hold one, no matter how small the job and no matter who they work for.

Layer two is the contractor license. It is issued to a business by the West Virginia Contractor Licensing Board. A company needs one, with a classification covering plumbing, once the total contract crosses a dollar threshold.

The Division of Labor states the relationship plainly in its own plumber FAQ: if three plumbers are working on a job, all three must individually hold a plumber certification, and their employer must hold a contractor license with a classification that covers plumbing. Neither substitutes for the other.

Two more facts from that same FAQ that catch people out:

• A plumber certification can only be issued to a person, never to an entity. Your company cannot "have" a plumber certification and cover its crew with it.
• A contractor license with the Plumbing classification does not let you personally perform plumbing work. The company is licensed. You still are not certified.

Layer one: the three plumber certifications

West Virginia Code §21-14-2 defines exactly three classifications. Note what the statute actually keys on, because it is not years of school and it is not a training program.

• Plumber in Training — statutorily defined as "a person who has not passed the journeyman plumber examination." That is the whole definition. There is no exam and no experience documentation for this tier. The statute also caps this fee at $25.
• Journeyman Plumber — "a person qualified by passage of a journeyman plumber written examination with a score of at least 70 percent" who is competent to instruct and supervise the work of a plumber in training.
• Master Plumber — a person who has passed a master plumber written examination with a score of at least 70 percent and who is competent to design plumbing systems and to instruct and supervise journeyman plumbers and plumbers in training.

The one-year rule that governs your entire timeline

Buried in §21-14-2(c) is the single most important scheduling fact in West Virginia plumbing licensure, and most guides skip it entirely:

"the master plumber written examination may not be taken until one year after passage of the journeyman plumber examination."

This is a hard statutory wait. It is not a rule of thumb and it is not waivable by documenting more experience. If you pass journeyman in March, your earliest possible master exam date is March of the following year. If your business plan depends on someone holding a master card by a certain date, count backward from that sentence first.

The Division of Labor states that all Master and Journeyman applicants must certify their experience and take a written exam. Plumber in Training requires neither.

What actually counts as "plumbing work"

This matters more than it looks, because it decides whether you need a card at all.

Code §21-14-2(e) defines plumbing as the practice, materials and fixtures used within a building in the installation, extension and alteration of all piping, fixtures, water treatment devices, plumbing appliances and appurtenances connected with sanitary or storm drainage; plumbing venting systems; medical gas systems; fuel oil and gas piping for residential, commercial and institutional facilities; backflow preventers; and public or private water supply systems as defined by the state building code.

The Division of Labor's plain-English version is narrower than most people assume: plumbing work is installing water lines, vents and drains inside a building. It explicitly does not include replacing faucets, replacing washers, unclogging sinks, or installing dishwashers.

So the fuel-gas and medical-gas piping in the statute is inside the scope. Swapping a faucet is not.

Eight statutory exemptions

Section 21-14-3(c) lists eight situations where no certification is required. In summary:

• Work you personally perform on a single-family dwelling you own or lease, or one owned or leased by an immediate family member.
• Plumbing at a manufacturing plant or industrial establishment, as an employee of the operator.
• Incidental plumbing performed by an employee of a retail appliance seller during installation or repair of an appliance the employer sold.
• Plumbing performed by a public utility or affiliate employee in connection with furnishing utility service.
• Installing, altering or repairing water distribution or drainage lines outside the foundation walls, public or private sewage or water treatment systems, sewers, or underground utility services.
• Plumbing work performed while installing, extending, dismantling, adjusting, repairing, servicing or altering an HVAC, air-veyor, air exhaust or air handling system.
• Work at an actively mined coal site or coal processing facility.
• Work at manufacturing, industrial and natural gas facilities.

That sixth one is the sleeper. An HVAC technician doing the piping incidental to a system installation is exempt from the plumber certification, which is why West Virginia's HVAC and plumbing tracks touch but do not overlap.

Fees, exam vendor and renewal

Plumber certification fees (West Virginia Division of Labor, verified September 2026):

• Master Plumber, initial certification and renewal — $75.00
• Journeyman Plumber, initial certification and renewal — $75.00
• Plumber in Training, initial certification and renewal — $25.00
• Duplicate certification — $10.00
• Late fee — $25.00

Fees are set by the Division of Labor and are subject to change. Verify current amounts with the Division before you write a check.

Notice how low those are. If you have seen a figure in the hundreds of dollars quoted online for a West Virginia master plumber license, you are almost certainly looking at an aggregator adding up an application fee, an exam fee and a license fee from a different state's structure. West Virginia's certification fee is $75.

Exam vendor: Prov, Inc. The Division of Labor names Prov (866-720-7768, provexam.com) as the testing vendor for plumber certification. Exam fees are set by Prov and change; confirm the current fee with Prov directly.

Renewal: the renewal date is printed on your certification card, and the Division says you should receive a renewal form roughly 45 days before it is due.

Grandfathering is long closed. The Division states the grandfathering period ended July 1, 2009. Everyone applying for Master or Journeyman now tests. There is no experience-only path.

Veterans: §21-14-3a lets a service member who completed a plumber, utilities worker or equivalent rating course submit the certificate and an honorable discharge with the application and fee, and sit the same examination as any other applicant. If more than 30 years have passed since completing that course, the Commissioner may require additional training first.

Penalties for working without a card

Section 21-14-7 sets a graduated structure, and the first step is not a fine.

Working without a certification gets you a cease and desist order. The fines attach to continuing after that order:

• First offense — not less than $200 and not more than $1,000
• Second offense — not less than $500 and not more than $2,000
• Third and subsequent offenses — not less than $1,000 and not more than $5,000

And the multiplier: each day after official notice that a person performs non-compliant plumbing work is a separate offense. A two-week job run after a cease and desist is not one violation, it is fourteen. The Commissioner can also go to circuit court for an injunction, represented by the Attorney General.

Penalty amounts are statutory and can be amended by the Legislature; verify against the current code.

One thing West Virginia does that helps you

Section 21-14-8 preempts local licensing outright: on and after January 1, 2009, no political subdivision of the state may require a person holding a valid Division of Labor plumber certification to hold any other license or evidence of competence as a plumber as a condition of performing plumbing work there.

That is a genuinely contractor-friendly provision and it is rarer than you would think. Your state card travels. You are not collecting municipal plumber cards county by county the way you would in states that leave licensure to cities.

Note the limit: this preempts local plumber licensing. It does not touch permits, inspections, business registration, or the separate contractor license.

Layer two: when your company needs a contractor license

This is where the individual track hands off to the business track, and where most one-truck plumbers get blindsided.

Under WV Code §30-42-3(d), a "contractor" is a person who, for compensation and other than as an employee of another, undertakes or bids construction work "where the cost of the undertaking is $5,000 or more for residential work or $25,000 or more for commercial work."

The Division of Labor's plumber FAQ applies that directly: plumbing work performed on a residential project of $5,000 or more, or a commercial project of $25,000 or more, requires a contractor license with the Plumbing classification. Critically, the FAQ specifies total contract amount, not just the plumbing portion. A $60,000 kitchen remodel where you are doing $6,000 of plumbing is measured against the $60,000.

Getting that license means passing two Prov exams: the Plumbing Contractor trade exam and the Contractor Licensing Act exam.

Plumbing Contractor exam (per the WV Contractor Licensing Board Candidate Information Bulletin, dated May 7, 2026): 100 questions, 3 hours, open book. Cut score 70%. Subject weighting includes Water Supply and Distribution (14 questions), Drain, Waste and Vent Systems (14), Isometrics (13), General Knowledge (10), Fuel Gas Systems (10), Plumbing Math (9), Safety (7), Water Heaters (7), Fixtures and Fittings (6), Storm Drainage (5) and Plumbing Tools (5). Primary references are the 2018 International Plumbing Code (53% of questions) and the 2018 International Fuel Gas Code (10%).

Contractor Licensing Act exam: 90 questions, 3 hours, drawn from WV Code Chapter 30 Article 42, Title 28 Legislative Rule Series 2, Title 28 Procedural Rule Series 4 (written contracts for services), and WV Code Chapter 21 Article 11A (notice and opportunity to cure construction defects).

Exams cost $59.95 each, first attempt or retake, per the Board's bulletin. There is no waiting period between attempts. Prov has four West Virginia testing centers (Charleston, Martinsburg, Morgantown and Wheeling) plus remote proctored testing. Exam fees are set by the Board and Prov and are subject to change.

The contractor license fee is capped by statute at $150 under §30-42-7(a). Verify the current amount with the Board, since the statute sets a ceiling rather than a fixed price.

One more §30-42-12 detail worth knowing before you bid anything: your contractor license number must appear on any bid submission, and a subcontractor has to furnish its license number to the general contractor before the contract is awarded.

Where the qualifier problem starts

Read §30-42-7(b) carefully, because one clause reshapes the whole hiring question:

"a license holder may hold a license on behalf of only one business entity during a given time period."

That is the constraint. The person whose exam results carry your contractor license can carry it for exactly one company. Not two. Not a parent and a subsidiary.

Then layer on the Board's own rule from its Candidate Information Bulletin: the qualifying individual taking the exam must be part of responsible management or a full-time employee of the entity seeking licensure. The Board's bulletin also notes a company can have multiple qualifiers, but backups are not permitted.

Put those together and the practical picture is this. If you are a plumbing company in West Virginia that needs a contractor license, you need a specific human being who has passed the Plumbing Contractor and Contractor Licensing Act exams, who is not already carrying somebody else's license, and who is genuinely inside your business as management or as a full-time employee. Not a name on a form. Not a consultant on retainer. A real, payrolled person.

That is the whole reason the qualifying agent role exists as a profession. When an owner has the crews, the customers and the work but nobody in the building holds the right exam credentials, the answer is to bring in a qualified individual as a full-time W-2 employee of the company. That is the only structure that satisfies what West Virginia's Board is actually asking for, and it is the only structure The Licensing Company uses. Percentage deals, per-project arrangements and "license rental" are not what the rule contemplates and are not something a reputable firm will offer you.

If you are on the other side of that equation, a master plumber with the credentials and no interest in running a company, becoming a qualifying agent is a way to put a license you already hold to work as a full-time employment position.

Frequently asked questions

How much does it cost to get a plumbing license in West Virginia?

The Division of Labor certification itself is inexpensive: $75 for Master or Journeyman, $25 for Plumber in Training. Add the Prov exam fee for Master and Journeyman applicants. If you also need the business-side contractor license, add two Prov exams at $59.95 each plus the Board license fee, which §30-42-7 caps at $150. Beyond those government and vendor fees, the real cost of getting a company licensed depends on your structure, whether you already have a qualified person inside the business, your insurance and bonding profile, and how many classifications you need. There is no single number, which is why we quote it against the actual situation on a consultation rather than publishing a rate card.

How long does it take to become a master plumber in West Virginia?

The binding constraint is statutory, not administrative. Section 21-14-2(c) prohibits taking the master plumber exam until one year after you pass the journeyman exam. So the minimum realistic sequence is: pass journeyman, wait a full year, then sit for master. Processing time at the Division of Labor is separate and on top of that.

Do I need a plumber certification if I subcontract all the plumbing work?

No. The Division of Labor's FAQ is explicit: a plumber certification is only required for the person who performs the work. If you bid and win a plumbing project but subcontract the actual work, or your employees perform it, you do not personally need the card. Your employees each do, and your company still needs the contractor license if the contract crosses the threshold.

Does a West Virginia contractor license with the Plumbing classification let me do plumbing work?

No, and this is the most common misunderstanding in the state. Since January 1, 2009, every individual performing plumbing work needs a plumber certification regardless of the job value or their affiliation with a licensed company. The contractor license covers the business. The certification covers the person.

Do I need a city plumbing license in Charleston, Huntington or Morgantown?

For plumber licensure, no. WV Code §21-14-8 bars any political subdivision from requiring a separate plumber license or other evidence of plumbing competence from someone holding a valid state certification. Permits, inspections and business registration are separate matters and still apply locally.

Is the $5,000 residential threshold changing?

There was a 2026 proposal to raise it. House Bill 5489, introduced February 13, 2026 by Delegate Campbell, would have amended §30-42-3 to move the residential figure from $5,000 to $10,000. Its last recorded action was referral to House Government Organization on the day it was introduced, and it did not become law. The current threshold remains $5,000 residential and $25,000 commercial. Watch future sessions, but do not plan around the higher number.

What does the Plumber in Training tier actually let me do?

It is the entry credential and it requires no exam, only a completed application and the $25 fee. The statute defines a plumber in training as someone who has not passed the journeyman exam, and the Division describes the role as a person with interest and aptitude who alone is not capable of performing plumbing work. In practice you work under the instruction and supervision of a journeyman or master.
