Before you sign anything

  1. Ask whose Master Plumber license the work runs under and check the 36BI number at newjersey.mylicense.com.
  2. On well water? Ask directly: how much of your work is on private wells and softeners? The wrong answer sounds like a pause.
  3. For emergency calls, ask the dispatch fee, the hourly or flat-rate structure, and whether travel time is billed, before anyone drives anywhere. That one question prevents most of this trade's billing horror stories.
  4. Water heater replacement should be quoted flat with the model number named. Tank swaps are commodity jobs; price them like one.
  5. Anything touching the septic line or the well equipment may cross into other licensed trades. The good shops tell you when it does.

The local picture

The local independents are strong but aging through ownership transitions, while franchise brands and a national drain chain contest the emergency-call market.

Questions neighbors actually ask

Is my plumber required to be licensed in New Jersey?

Yes. New Jersey licenses Master Plumbers individually through a state board, and plumbing businesses operate under a licensed master’s number (starting 36BI). Check at newjersey.mylicense.com.

Why is the emergency rate so high?

Nights and weekends legitimately cost more; the abuse is in how the meter runs. The billing practices worth asking about up front: dispatch fees, minimum hours, mandatory two-person crews, and travel time billed at the emergency rate.

Tank or tankless water heater?

On well water, the honest answer starts with your water quality: hard or iron-heavy water scales tankless units and eats their efficiency without pretreatment. A shop that asks about your softener before quoting tankless is a shop that's done this here before.
