How to Hire a Plumber in Utah (2026)

Plumbing work is one of the most license-regulated trades in Utah — and for good reason. Faulty plumbing causes water damage, mold, and health hazards. Here's how to hire right.

Licensing Requirements

Utah requires plumbers to hold a DOPL license (S340 category). There are three levels:

• Apprentice Plumber — Works under supervision, cannot pull permits
• Journeyman Plumber — Licensed to do most work
• Master Plumber — Can pull permits, supervise others

Always verify a plumber's license at the DOPL website before hiring.

What Plumbers Should Cost in Utah (2026)

• Service call / diagnostic: $75–$150
• Drain cleaning: $100–$300
• Water heater replacement: $800–$1,800 installed
• Full bathroom rough-in: $3,000–$8,000
• Whole-home repipe: $5,000–$15,000

Red Flags to Avoid

1. No license number available — Walk away
2. Demands full payment upfront — Standard is 50% down, 50% on completion
3. Won't pull permits — Unpermitted plumbing kills home sales
4. No written estimate — Get everything in writing
5. Unusually low bid — Usually means inexperience or cut corners

Questions to Ask

• Are you licensed with DOPL? What's your license number?
• Do you pull permits for this type of work?
• What's your warranty on parts and labor?
• Are you insured for property damage?
