How to Choose the Right Plumber: Credentials, Questions, and Red Flags

When your basement fills with water or the kitchen sink won’t drain, you need help. Fast. Choosing the right plumber can mean the difference between a quick fix and a long, costly headache. It’s not just about stopping the leak—it’s about peace of mind for your family or business.

At National Plumbing, we understand how stressful a plumbing emergency can be. That's why we’re here to help you know what matters most when hiring a plumber—so you get it right the first time.

Must-Have Credentials: The Real Mark of a Pro 🛠️

Think of credentials as a plumber's ID badge—proof they're qualified to be in your home or business. Without them, you’re taking a risk. Here’s what to look for:

Licensing

A licensed plumber has proven knowledge of local building codes, safety standards, and best practices. States and municipalities require licensing for good reason. Always ask to see a physical license, and don’t be shy—reputable plumbers expect the question.

• Tip: You can verify a plumber’s license through your state’s licensing board or local municipal website.

Insurance

Accidents happen. Without insurance, you could be liable for injuries or property damage. A trustworthy plumber carries both general liability and workers’ compensation insurance.

• Why it matters: If a pipe bursts or a tool goes flying, you won’t be left holding the bill.

Certifications

Look for plumbers who invest in ongoing training. Certifications from organizations like the Plumbing-Heating-Cooling Contractors Association (PHCC) or the American Society of Plumbing Engineers (ASPE) show dedication to the craft.

Background Checks

You’re inviting someone into your home or business. Ask if technicians are background-checked. At National Plumbing, every team member is thoroughly vetted for your safety.

Questions to Ask Before Hiring

Before you say “yes,” have a real conversation. Here are the questions that matter—whether you’re searching for “Pipe Repair near you” or emergency plumbing help at 2 a.m.

• Are you licensed and insured? (Get proof, not just a quick “yes.”)
• How long have you been in business? Longevity signals reliability.
• What’s your experience with my issue? Not all plumbers tackle gas line installation, leak detection, or complex commercial plumbing.
• Do you offer written estimates? Verbal quotes can disappear like water down a drain.
• Are your rates flat or hourly? Understand what you’ll pay—and what’s included.
• What’s your emergency response time? Emergencies can't wait.
• Do you warranty your work? Ask about the details.
• Can you provide references or reviews? Real feedback paints the clearest picture.

A solid plumber welcomes these questions. It shows you care about your property—and so should they.

Red Flags to Watch For 🚩

Not every plumber is a keeper. Some signs should send you running in the other direction.

• Unclear or shifting pricing. If you can’t pin down the cost, beware.
• No proof of licensing or insurance. No papers, no deal.
• Reluctance to provide references. A good reputation speaks for itself.
• Poor or few reviews. Check Google and trusted review sites.
• High-pressure sales tactics. A reliable plumber lets you choose—no scare tactics.
• Unmarked vehicles or lack of uniform. Professionals look the part.
• No physical address. Fly-by-night outfits vanish overnight.

If something feels off, trust your gut. Plumbing is too important for second guesses.

Practical Tips for Choosing Your Plumber

• Check local regulations. Plumbing codes vary, and the right pro knows your area’s rules.
• Get multiple bids. Don’t settle for the first estimate, especially for big jobs like repiping or boiler repair.
• Read the contract. Make sure you understand what’s included—and what isn’t.
• Ask about cleanup. A true professional leaves your space better than they found it.
