How to Choose an Oil Tank Sweep Company in NJ
Most people hire an oil tank sweep company under time pressure. The home inspection came back, the buyer’s attorney mentioned the heating history of the house, and closing is a few weeks away. A few clear questions will tell you a lot about who you are dealing with.
Start with what the state does and does not certify
New Jersey certifies the people who remove underground heating oil tanks and the people who investigate and clean up a leak. According to the NJDEP’s homeowner FAQ, removing an underground tank requires a closure-certified individual working for a closure-certified firm, and investigating a leak requires a certified subsurface evaluator or a Licensed Site Remediation Professional.
A sweep, which only locates a tank, is a different service. The NJDEP’s FAQ does not describe a state certification for sweeps. So “certified sweep inspector” is not a credential you can look up. That is why the questions below matter more than a logo on a truck.
Ask how they search
A good company can explain, in plain words, what equipment it uses and why. Metal detection and electromagnetic locators respond to buried steel. Ground penetrating radar builds a picture of what is under the surface and can also show tanks that are not metal. Many properties are best checked with more than one method, because each has blind spots.
If the answer is vague (“we have a machine”), keep asking. If the company can describe the method used on your type of lot, that is a good sign. You can read how we approach it on our oil tank sweep page and our ground penetrating radar page.
Ask what the report will say
You are paying for the answer, not the walk around the yard. A useful report states what area was searched, what methods were used, what was found, and where. Photos and a simple sketch of the property help. Honest reports also say what could not be searched, such as an area under a deck, a driveway, or thick brush.
Be wary of a company that promises it will “find everything.” Reports from tank sweeps commonly note that no sweep can guarantee detection of every target, because vegetation, structures and buried utilities limit what the equipment can see.
Ask what happens next
Sometimes a sweep finds nothing. Sometimes it finds a signal that could be a tank, a pipe or buried debris. The next step is usually an exploratory dig, a small excavation that confirms what is down there. Ask whether the company does that work, what it costs to add, and who handles removal if a tank turns up.
Ask for proof, not promises
Ask for proof of insurance and make sure the company name matches the one on the quote. Read recent reviews and look for details: did the company arrive when it said it would, and did the report answer the question? Ask whether the company works with real estate agents and attorneys and understands closing deadlines.
About price
The cheapest quote is not always the best one, and the most expensive is not always better either. Compare what each quote includes: area searched, methods, written report, and travel. A quote you can compare line by line beats a low number you cannot explain.
