Above Ground Oil Tank Removal Cost (2026)

What Is an Above Ground Oil Tank?

Above ground oil tanks (ASTs) are storage tanks that sit on a basement floor, utility room, or outdoors on a pad. They were common in homes built before 1980 that used heating oil. Even though they are easier to access than underground tanks, removing them still requires a licensed contractor in most states.

What Affects the Cost?

1. Tank Size

2. Location of the Tank

A tank in an open basement is the easiest scenario. Costs increase when the tank is in a crawl space, needs to be cut to fit through a doorway, or requires special equipment to access.

3. Remaining Oil

Contractors must drain any remaining heating oil before removal. Pump-out typically costs $0.25-$0.50 per gallon.

4. Soil Testing

Many states require soil sampling after removal. Soil testing typically costs $300-$800 depending on sample count and your state.

5. Contamination

If heating oil has leaked, remediation costs stack on top of removal:

• Minor contamination (contained): $2,000-$5,000
• Moderate contamination: $5,000-$15,000
• Major contamination (soil + groundwater): $15,000-$50,000+

Many states have environmental cleanup funds that offset remediation costs for homeowners. Ask your contractor about eligibility.

Above Ground vs Underground Tank Removal

Above ground tanks are almost always cheaper to remove. Underground removal requires excavation, adding $2,000-$5,000+ before you even reach the tank. If you have both types, some contractors bundle the job for a discount.

Do I Need a Permit?

Permit requirements vary by state. In New Jersey, Connecticut, and Maryland, permits are almost always required. A licensed contractor will pull the necessary permits as part of their service.

How to Get the Best Price

• Get at least 3 quotes. Prices vary significantly between contractors.
• Ask what is included. The quote should cover drain, clean, cut, haul, and disposal.
• Verify licensing. Unlicensed contractors create liability issues that cost far more later.
• Ask about state cleanup fund eligibility if there is any chance of contamination.
