How to Choose a Plumber in Tucson: 7 Questions to Ask Before You Hire

In a market with dozens of plumbing companies serving Tucson, the difference between a great experience and a costly one often comes down to questions you ask before the technician arrives — not after. Here are the seven questions every Tucson homeowner should ask, and the answers that indicate a legitimate professional contractor.

1. Are You Licensed by the Arizona ROC?

Arizona's Registrar of Contractors (ROC) licenses all contractor categories, including plumbing. A licensed plumber has passed state examinations, carries required insurance, and is subject to oversight. You can verify any license number at the ROC website (azroc.gov). Ask for the license number and look it up — takes 30 seconds. A legitimate contractor will give it to you without hesitation. Trusted Plumbing's license: ROC #361362.

2. Do You Carry Liability Insurance and Workers Comp?

Liability insurance covers damage caused by the contractor's work. Workers' comp covers their employees if injured on your property. Without both, you may be liable for injuries that occur during a job at your home, and damage caused by uninsured work is your problem. Ask for a certificate of insurance and ask it to be provided before work begins.

3. Do You Give Upfront Written Pricing Before Starting Work?

A professional contractor provides a written quote that you approve before any work begins. Time-and-materials billing ('we charge $X per hour and we'll see how long it takes') is appropriate in some diagnostic situations, but for any defined repair, you should know the total cost before work starts. If a plumber is reluctant to commit to a price before opening your wall or your drain line, that is a significant warning sign.

4. What Warranty Do You Provide on Your Work?

A professional plumber stands behind their work with a written warranty on workmanship — meaning that if the repair fails due to their work, they return and fix it at no charge. Ask for the warranty term and what it covers. A 90-day warranty is the minimum for a credible contractor; longer terms on specific services reflect greater confidence in the work.

5. Are Your Technicians Licensed or Just the Company?

In Arizona, the business license covers the company, but individual technicians should be supervised by or trained under a licensed master plumber. Ask whether the person coming to your home is a licensed journeyman plumber or an apprentice, and whether a licensed plumber reviews all work before job completion. This matters on anything beyond basic fixture replacement.

6. Do You Pull Permits for Work That Requires Them?

In Tucson and Pima County, plumbing work beyond simple fixture replacements requires a permit. A contractor who offers to 'skip the permit to save you money' is asking you to accept unpermitted work that can affect your insurance coverage and resale disclosure requirements. Permits exist because inspections exist — they protect you, not just the contractor.

7. What Do Your Recent Reviews Say — and Can I Speak to a Reference?

Google reviews tell you something, but they are curated by recency and volume. Ask for a recent reference in your neighborhood or for a similar job type. A contractor who cannot provide a satisfied recent customer for a reference is a contractor who does not expect you to follow through — which tells you something.
