How to Hire a Plumbing Professional — What to Look For

A bad plumber can turn a simple fix into a costly nightmare. Whether you're replacing a faucet, fixing a leak, or rerouting your sewer line, choosing the right professional is key. This isn't about vague recommendations; it's about knowing what to ask, what to watch for, and how to avoid getting burned.

Below is a straightforward, no-fluff guide based on 20 years of trade experience. Follow it, and you'll significantly reduce your risk of hiring a bad plumber.

What a Good Plumbing Professional Looks Like

1. Licensing

• Ask for their license number upfront.
• Verify it through your state’s licensing board (most states have online databases).
• Confirm the license is current and in good standing.

2. Insurance

• Request a current certificate of insurance for general liability (minimum $1 million coverage) and workers' compensation if they have employees.
• Contact the insurance provider if you want to verify coverage.

3. Written Estimates and Contracts

• Get the estimate before work begins.
• Ensure it spells out the scope of work clearly.
• Ask if there are potential additional costs (e.g., unforeseen repairs).

Red Flags to Watch For

• No licensing or license not verifiable.
• Demand full payment upfront — especially without a contract.
• No written estimate or contract.
• Unusually low bid — often a sign of cutting corners or using subpar materials.
• Pressure to sign immediately or discourage getting other quotes.
• Refusal to pull necessary permits.
• Lack of references or poor reviews online.
• Disorganized or unprofessional appearance, such as a dirty truck with no branding or license info.
• Unwillingness to show proof of insurance.
• Using unlicensed subcontractors without disclosure.

Key Questions to Ask

• Are you licensed and insured in this state?

• Can you provide references from recent jobs similar to mine?

• Will you handle pulling the necessary permits?

• What warranty do you offer on parts and labor?

• Who will actually do the work — you or a subcontractor?

Practical Tips for a Smooth Hire

• Get everything in writing. Never rely on verbal promises.
• Check reviews and references. Contact at least two previous clients. Ask about timeliness, quality, and if they’d hire the same plumber again.
• Inspect their license and insurance. Call the licensing board if necessary.
• Ask about permit handling. A reputable plumber will pull permits and coordinate inspections.
• Avoid cash-only deals or offers that seem “too good to be true.” These often hide subpar work or illegal practices.
