Plumber: resume screening criteria template
Successful plumbers show proof they can handle real service calls independently, not just apprentice work under supervision. They troubleshoot problems, work cleanly in customers' homes, and finish jobs without callbacks. The biggest screening mistake is overvaluing certifications while ignoring actual hands-on experience with residential service work, particularly whether they've run calls solo versus just assisted a lead plumber.
The second mistake is not checking for customer interaction skills. A plumber who can explain options to homeowners, show up on time, and leave jobsites clean will generate repeat business and referrals. Look for evidence they've worked directly with customers, handled money, or received positive feedback, not just pipe-fitting skills in new construction where they never met the end user.

The criteria (6)
Residential Service Experience
weight 10/10Resume shows at least 2 years performing service calls, repairs, and installations in occupied homes as primary duty, not just new construction or commercial work.
Strong evidence: Phrases like 'responded to 8-12 service calls daily,' 'diagnosed and repaired residential plumbing emergencies,' or 'performed drain cleaning, fixture replacement, and water heater installation in homes.'
Red flag: Only lists new construction, commercial pipefitting, or apprentice work where they clearly assisted rather than led jobs.
Valid Licensing
weight 9/10Resume lists a current journeyman or master plumber license with license number, or shows active progress toward licensing with documented apprenticeship hours.
Strong evidence: Includes specific license number and state (like 'Licensed Journeyman Plumber, State of Ohio, #12345') or 'completing 4th year apprenticeship, 6,800 hours logged.'
Red flag: No license mentioned, expired license, or vague claims like 'certified plumber' without specifics or state designation.
Diagnostic Skills
weight 8/10Resume demonstrates ability to identify problems, not just follow instructions, through troubleshooting language or variety of repair types handled.
Strong evidence: Uses terms like 'diagnosed slab leaks using electronic detection,' 'troubleshot low water pressure issues,' or lists diverse repairs beyond basic fixture swaps.
Red flag: Only mentions installing new fixtures or following blueprints with no language about figuring out existing problems or repairs.
Customer Communication
weight 7/10Resume shows direct customer interaction through sales, estimates, explaining options, or customer service recognition.
Strong evidence: Includes phrases like 'provided repair options and pricing to homeowners,' 'maintained 4.8-star customer rating,' or 'generated $180K in annual sales through service recommendations.'
Red flag: No mention of customers, homeowners, or client interaction, suggesting they only worked on job sites without end-user contact.
Reliability Indicators
weight 6/10Resume shows job stability with at least one position lasting 2+ years, or provides references, or mentions on-call or emergency service work.
Strong evidence: Shows tenure like '2018-2023' at one employer, states 'available for on-call rotation' or 'responded to after-hours emergency calls,' or lists 'references available upon request.'
Red flag: Job-hopping with five or more employers in three years, or gaps in employment without explanation.
Broad Technical Range
weight 6/10Resume lists experience across multiple plumbing systems including drain cleaning, water heaters, fixtures, gas lines, or sewer work, not just one specialty.
Strong evidence: Mentions varied work like 'installed tankless water heaters, cleared main line stoppages, replaced sewer laterals, installed gas lines for appliances.'
Red flag: Resume only mentions one narrow type of work like 'drain cleaning' or 'fixture installation' suggesting limited versatility.

FAQ
Should I require a master plumber license or is journeyman enough?
For most small business service work, a journeyman license is sufficient and opens your candidate pool significantly. Master licenses are required to pull permits and supervise others in most states, so you need one if you plan to handle commercial jobs or hire apprentices. If you're the business owner with a master license yourself, hiring journeyman plumbers to run service calls is the standard model. Just verify their license is active in your state before making an offer.
How important is new construction experience versus service work?
They're very different skill sets. New construction plumbers follow blueprints and rough-in systems in open walls, while service plumbers diagnose problems, work in finished spaces, and deal with customers. If you run a service business, prioritize service experience heavily because new construction guys often struggle with troubleshooting and the customer interaction required on service calls. A service plumber can learn construction, but construction plumbers often dislike the unpredictability and customer-facing nature of service work.
What if someone has great experience but no formal license?
This depends on your state laws and insurance requirements. Most states require licensed plumbers for anything beyond basic maintenance, and your liability insurance likely requires it too. If they have strong verifiable experience but no license, check if they're eligible to test for their journeyman license soon based on apprenticeship hours. You might hire them as an apprentice at lower pay while they complete licensing, but don't hire unlicensed workers to do licensed work independently or you risk fines, failed inspections, and insurance claims being denied.
