Oil tank removal cost in New Jersey
The removal is usually the smaller bill. The number that matters is whether the soil around the tank is clean.
| Job | Typical NJ cost | Notes |
|---|---|---|
| Tank sweep | $300 – $500 | Searches the yard for a buried tank. Not part of a standard home inspection. |
| Underground tank removal, clean soil | $2,000 – $5,000 | Includes pumping, excavation, soil samples and backfill. A town permit is required. |
| 550-gallon tank removal | $2,100 – $2,300 | Average NJ figure reported for the most common residential size. |
| Soil cleanup after a leak | $10,000 – $100,000+ | Depends on how far oil spread and whether groundwater was reached. |
What moves the price
- Tank size and depth, and whether it's under a driveway, porch or addition.
- Town permit and inspection fees, which differ from town to town.
- Soil test results. Clean samples close the job. A leak turns it into a reported cleanup.
- Access for equipment in tight yards.
How buyers and sellers handle it
Most sellers either remove the tank before listing or give the buyer a credit. Buyers usually ask for the estimated removal cost plus a cushion of 15 to 25 percent in case contamination turns up. Get the sweep done early so there's time for quotes.
