Hiring and keeping plumbers and apprentices

Ask any owner what caps their growth and you will usually hear the same answer: not leads, not trucks, but people. Good plumbers are hard to find and easy to lose, and the ones you train up are the ones a bigger shop will try to poach. Building a crew that stays is less about paying the most and more about being the shop a good plumber does not want to leave. Both hiring and keeping matter, and they are different problems.

Grow your own more than you hunt

The finished journeyman you want is also the one everyone else wants, so competing purely on offers is a losing game. The shops with stable crews mostly build them, taking on apprentices and helpers and bringing them up. It is slower, and yes, some will leave once they are trained, but the ones who stay know your systems, your customers, and your standards in a way no lateral hire ever will.

That means you need an actual path, not just a warm body riding shotgun. Pair the apprentice with a plumber who can teach, give them progressively harder work, and be clear about what earns the next raise and the next level of responsibility. An apprentice who can see the ladder climbs it. One who feels like permanent cheap labor leaves the day something better calls.

Hire for attitude, verify the rest

Skills you can teach, and code knowledge you can check. What you cannot install in a hire is showing up on time, treating a customer’s home with care, and telling you the truth when a job goes sideways. Interview for those, and lean hard on references from people who actually worked with the candidate, not the names they hand you.

For a licensed hire, verify the license and confirm they can do the work you are hiring for, not just talk about it. A ride-along on a real job tells you more in half a day than an hour across a desk. Watch how they treat the homeowner and how they handle a surprise in the wall.

Keep the ones you have

Retention is mostly the boring stuff done consistently. Pay fairly and on time, keep the trucks stocked so techs are not scavenging for parts, and back them when a customer is unreasonable. Plumbers quit chaos and disrespect far more often than they quit over a small pay gap.

Give them tools that make the day easier too. A field-service app that lets a tech quote and collect in the driveway removes the paperwork they hate. See the software guide for that. And when the pipeline is dry, that is felt in the truck as much as in the office, so keeping work flowing is a retention tool. Browse vetted pros and suppliers in our directory.

Make leaving cost something

You will never win by locking people in, but you can make staying the obviously better deal. Tie raises to earned skill, share a little of the upside when the shop has a good year, and build enough bench that no single departure sinks you. The owner who treats plumbers like the scarce, valuable people they are keeps a crew. The one who treats them as interchangeable spends every year rehiring.
