Removing a buried residential heating-oil tank in New Jersey typically runs about $1,500–$3,000 when there's no leak. A leaking tank means soil remediation, which can push the total into five figures — which is why a pre-purchase sweep (~$200–$500) matters. A certified firm gives a firm quote after locating and assessing the tank.
Yes. Underground tank closure and removal in New Jersey is regulated by NJDEP and the local construction and fire officials — the work must be done by an NJDEP-certified firm, with permits pulled and the closure properly documented. That paperwork is what protects you and any future buyer.
26 NJDEP-certified UST firms are based in Middlesex County, and statewide firms serve Metuchen as well.
