The installer matters more than the brand. Here's how to separate a pro from a problem before you hire.
You can buy the best water heater on the market, but if it's installed poorly it'll fail early—or worse, create a safety hazard. The installer matters more than the badge on the tank. Here's how to choose a good one in New Jersey.
Non-negotiables
- Properly licensed (NJ requires licensed plumbers for this work)
- Pulls the required permit and schedules the inspection
- Carries insurance
- Gives a written, itemized estimate
- Includes code upgrades (expansion tank, venting, T&P discharge)
Green flags
- Explains the work and answers questions patiently
- Recommends the right unit for your home, not the priciest
- Stands behind the work with a labor warranty
- Has a real local presence and reviews
- Discusses maintenance to protect your investment
Red flags to avoid
- A quote far below others (often skips permit/code work)
- Won't pull a permit or says you 'don't need one'
- Cash-only, no written estimate, no license number
- Pressures you to decide on the spot
- Vague about what's included
The cheapest quote is often the most expensive in the end—it usually leaves out the permit, the expansion tank, or proper venting that you'll pay to fix later.
Questions to ask
- Are you licensed and insured in NJ? (Get the license number.)
- Will you pull the permit and handle the inspection?
- Is the expansion tank and disposal included?
- What labor warranty do you offer?
- Is the estimate written and itemized?
