| Labor & Installation | $1,000 | $2,200 | $3,800 | Removal, site prep, install, testing. |
| Permits & Inspections | $200 | $600 | $1,000 | Local rules vary by county. |
| Delivery & Removal of Old Tank | $150 | $350 | $800 | Hauling; disposal fees may apply. |
| Contingency & Misc | $150 | $400 | $900 | Unforeseen fixes; trenching, seals. |
| Total Project Range | $2,700 | $5,550 | $9,500 | Prices reflect common scenarios with varied labor + permits. |
Overview Of Costs
Typical cost range for replacing a 275 gallon oil tank spans from roughly $2,700 to $9,500, depending on tank material, installation complexity, and local permit requirements. The per-unit influence often comes from the tank type (steel vs fiberglass), soil conditions, and whether existing piping needs upgrading. The project can be broken into two broad parts: hardware and labor plus regulatory steps. For a straightforward replacement in a standard residential setting, expect the middle of the range, around $4,800-$6,200, with higher-end jobs reaching near $9,500 when excavation or corrective work is necessary.
Assumptions: standard steel 275 gal tank, basic piping, level site, in-ground install where permitted.

What Drives Price
Tank material and condition primarily affect hardware costs. Steel tanks are typically less expensive upfront but may require more corrosion protection; fiberglass options can be pricier but offer longevity. Assumptions: fiberglass adds roughly 25–40% to tank cost versus steel.
Installation complexity includes soil type, existing piping, distance to vent and fill, and whether a trench or sump is needed. In-ground installations with difficult access often raise labor and equipment costs.
Regional Price Differences
Prices vary by region due to labor rates, permitting fees, and disposal costs. In the Northeast, higher permit activity can push totals toward the upper end of ranges. The Midwest often shows mid-range totals, while parts of the South may trend lower due to labor and disposal variations. Expect regional deltas in the ±10–30% band for both materials and labor.
Labor, Hours & Rates
Typical installation takes 6–18 hours depending on site access, tank type, and backfill requirements. Labor rates commonly range from $70 to $180 per hour for licensed installers. For trenching or soil remediation, additional hours may be needed and drive up the final price.
Assumptions: standard city/urban settings with accessible plumbing and minimal backfill.
Additional & Hidden Costs
Hidden costs can include old tank certification, soil remediation, extra piping, venting upgrades, or emergency service calls outside normal hours. Some jurisdictions require a soil test or concrete pad installation, which adds $300-$900 more to the project. Always confirm whether removal of a contaminated tank triggers additional disposal fees.
Assumptions: no major environmental hazards; standard disposal permitted through local waste authority.
