The question checklist
Two lists. The first protects your decision, the second protects your wallet. Together they take an hour or two of work and can save four or five figures.
Most expensive tank mistakes happen before the excavator arrives: signing with the first contractor who calls back, skipping the records search, or taking a "free removal" pitch at face value.
Before you decide
Nine things to confirm while you still have every option open.
- Confirm the tank's location and status. Vent pipes, fill caps, and a professional sweep tell you whether a tank exists and where — how to tell if you have an underground tank.
- Pull property records and permits. Your municipality's construction office may hold installation permits, prior closure permits, or nothing at all — and "nothing" is itself useful information.
- Find any prior closure documentation. If a previous owner claims the tank was removed or closed, get the closure report and soil results; an undocumented closure is treated as an open question by buyers and lenders.
- Confirm the contractor is licensed and compliant. Verification takes minutes and eliminates most bad outcomes before they start — how to choose a contractor, and the state registries.
- Understand the cost drivers before the first quote. Access, soil, groundwater, and tank contents move the number, and knowing which apply to you makes a padded quote obvious — the 2026 cost guide.
- Understand what a leak would mean. Confirmed contamination moves the job into a separate remediation tier under state oversight, so know that branch before you're standing at an open pit — the leak and remediation guide.
- Get soil testing if you're selling. Clean lab results are what buyers' attorneys actually ask for, and getting them on your own timeline beats getting them during attorney review — selling with a tank.
- Check the grant and insurance reality. The UST Fund is backlogged and the non-leaking program has been suspended since 2011, so budget as if no state money is coming — what relief actually exists.
- Secure closure documentation for future resale. The closure report, disposal records, and soil results are the proof the next buyer's attorney will demand; file them like a deed.
Questions to ask any contractor
Ask all nine of every contractor who quotes you. A good one answers without flinching.
- Are you licensed and compliant in this state? A good answer names the specific licences and offers to show them; hesitation or "we work under a partner's licence" is a walk-away.
- Do you handle permits? A good answer is "yes, we pull the municipal permit and it's line-itemed in the quote" — not "the town doesn't really check."
- What exactly is in the quote — permits, disposal, sand or foam extraction, restoration? A good answer itemises each; a single round number with "everything's included" usually means something isn't.
- Is soil sampling included? A good answer states how many samples, who runs the lab work, and what the results cost if they're extra — sampling is what proves the job ended clean.
- What happens if you find contamination mid-job? A good answer describes stopping work, documenting conditions, and giving you a separate remediation scope to approve — not rolling new charges into the open job.
- Do you provide disposal documentation and a closure report? The only good answer is yes, in writing, as a deliverable — this paperwork is half the reason you're paying.
- Are you insured and bonded? A good answer includes a certificate of insurance on request; "we've never had a problem" is not coverage.
- Do you promise "free" state-funded work? A good contractor won't make the promise at all and will tell you the fund is backlogged; one who leads with "free" is selling you a claim they can't control.
- Any warranty? A good answer specifies what's warranted (workmanship, restoration) for how long, in writing; a verbal "we stand behind our work" specifies nothing.
"Free tank removal, the state pays" is common enough that NJDEP explicitly warns homeowners about it. The UST Fund accepts and date-stamps new applications but does not review them until funding is available, and the non-leaking-tank program has been suspended since May 3, 2011. A contractor who guarantees state money is guaranteeing something the state hasn't. If the job only makes sense to you at "free," don't sign — the relief screener shows what your state actually offers.
