How to Choose a Plumber in Connecticut

Step 1: Verify the license — it's Connecticut law, not a formality

Connecticut licenses plumbers in two main grades: P-2 (journeyman), who performs the work, and P-1 (contractor), who can run the business and pull permits. Plumbing work on your home must be done by a licensed plumber or a registered apprentice working under one. Ask for the license number — every legitimate plumber carries it and prints it on trucks, invoices, and quotes — and verify it through the Connecticut Department of Consumer Protection's online license lookup. It takes two minutes and it is the single most effective filter in this entire guide.

Why it matters beyond the law: unlicensed work can void your homeowners insurance coverage for resulting damage, surface as an unpermitted-work problem when you sell, and leave you with no DCP complaint path if the job goes wrong.

Step 2: Match the company to the job

• Big-ticket underground work (sewer, water service): you want a company that owns its camera and excavation equipment and does this weekly — not a generalist renting a machine for the first time on your yard.
• Water heaters and fixture work: any well-run residential shop handles these daily; speed and warranty terms matter more than specialization.
• Emergencies: the best emergency plumber is often the company that already knows your house. If you find a good one on a small job, keep the relationship warm before January does its work.

Step 3: Read the quote like a contract (because it is one)

• Itemized scope: pipe material and footage, equipment make and model, depth and route on underground work — not "fix sewer, $8,000."
• Restoration: who patches the driveway, the wall, the lawn — and to what standard. If it's not written, it's not included.
• Permits: named in the quote, pulled by the plumber, inspection included.
• Warranty: labor warranty length in writing (one year is a reasonable floor for major work), separate from the manufacturer's parts warranty.
• Change-order rule: how surprises found mid-job get priced and approved — before they're done, in writing.

Questions that separate pros from order-takers

• "Can I see the camera footage of my sewer line — and do I get a copy?" (For any sewer diagnosis beyond a cleaning.)
• "If this were your house and your money, repair or replace — and why?"
• "What's NOT included in this price that I might end up paying for?"
• "Who actually does the work — your licensed crew or subcontractors?"
• "What does your labor warranty cover, and for how long?"

Red flags, in rough order of seriousness

• No license number, or resistance to providing it. Walk away.
• A sewer replacement quoted without a camera inspection. That's a guess wearing a uniform.
• Pressure to decide today on a non-emergency job, especially with a "discount that expires."
• Cash-only, or a large deposit before work starts on a routine job. Modest deposits on big scheduled projects are normal; most of the money should move when work is complete.
• Suggesting you skip the permit "to save money." The savings are theirs, the risk is yours.
