Your comfort is our priority — and has been since day one.
On Call NJ was founded on a simple frustration shared by homeowners everywhere: when something goes wrong with your plumbing, heating, or cooling, it's nearly impossible to find a company that answers the phone, shows up when they say they will, and charges a fair, honest price.
We set out to be that company for Northern New Jersey. Today, our licensed and insured technicians serve more than 200 towns across Bergen, Essex, Hudson, Morris, Passaic, Sussex, Union, and Warren counties, handling everything from middle-of-the-night burst pipes to planned water heater installations.

Every decision we make comes back to one idea: treat every customer's home the way we'd want our own treated. That means:
We're fully licensed and insured, so every job is done to code and you carry zero liability. Just as importantly, we're local. We know these towns, the age of the housing stock, and the problems that come with Northern New Jersey's climate and water. That local knowledge means faster, more accurate service for you.



Our promise: When you call On Call NJ, you reach real people who care about getting your problem solved — day or night, every day of the year.
