What oil tank removal costs in Long Island
There is no fixed tank-removal price in this guide, because none of the 20 companies publishes a fixed tank-removal price on its own website. Every dollar figure on this page is a range, an average, a discount, a coupon, a guarantee or a public fee found on a company's own site, labeled as such. None of them is a fixed price for every home, and none of them is a quote for your home: final prices depend on the tank type and size, whether it is above ground or buried, access, soil condition, permits, and how much work the job takes, as the companies themselves state.
Published figures (labeled, never fixed removal prices)
- Lighthouse Oil Tank Services: a new 275-gallon tank supplied and installed, an average of $2,990 to $3,790 (standard Granby 275 at $2,990; Granby 275 Ecogard at $3,590; Roth 275 at $3,790; each average includes removal and disposal of the old tank, oil transfer and sludge disposal). These are installed-tank averages, not a removal-only price. Abandonment: around $800 to $1,500 or more, a range, not a fixed price. Removal alone, without replacement, has no published price.
- All Island Mechanical: a conversion range of $5,000 to $15,000. That is a conversion range, NOT a removal price, because its old-tank removal is offered only within oil-to-gas conversions.
- Certified Oil Tank Services of Nassau County: a leak-cleanup range of $4,500 to $15,000. That is a leak-remediation range, NOT a removal price.
- Domino's Oil Tank Service: a discount promotion of $50 off any oil tank project. That is a coupon, not a price.
- Oil Tank Abandonment Long Island: a price-match guarantee, promising to beat a lower price by $100. That is a guarantee, not a price.
- Levittown Oil Tank Services: new Roth and Granby oil tank installations start at $2,800. That is a starting installation figure, NOT a removal price. The company says expressly that it does not quote flat rates sight unseen.
- Windmill Oil Tank Service: an old and ambiguous figure for a new 275-gallon Granby tank at $600 on its older About page, without clarifying whether installation is included. That is an old and ambiguous figure, never a removal price, and it conflicts with the installed-tank averages above.
- Burt's Reliable: no fixed price. Its site says the cost can run to several thousand dollars, and cites a potential leak-cleanup cost of $20,000 or more if there is a leak. That figure is a potential leak-cleanup cost, NOT a service price.
- All Island Comfort: no tank price. Figures it mentions for heat-pump rebates, $4,000 to $7,500, are rebates, not a removal price.
- Domino Fuel: no fixed price. Its own site says expressly that there is no flat rate and offers a free written estimate. Its abandonment page cites ranges for abandonment of $1,000 to $3,000 and for removal of $593 to $2,155, attributed expressly on that page to HomeAdvisor and Angi national averages for 2026. Those are third-party national averages, NEVER Domino Fuel's own prices.
- Every other company in this guide publishes no price figure at all. Several offer a free estimate, a free consultation or a free quote instead.
Public fees are not company prices
Nassau County Department of Health, Article XI: a public county fee of $90 for a tank removed and $70 for a tank abandoned in place, with 7 days of notice before the work. The Village of Hempstead municipal permit fee cited on a company site is $25 for a boiler plus $20 for a gas meter. These are public fees, not prices charged by any company in this guide, and they are never presented as company prices.
What drives a tank-removal quote
- Tank type and size: above-ground, basement or buried tank, and its capacity.
- Condition: age, corrosion, whether the tank has leaked, and what soil testing finds.
- Access: how easy it is to reach, cut and haul the tank, and whether excavation is needed.
- Permits: county notice and permit requirements, which vary with the county and the job.
- Scope: removal only, abandonment in place, or removal plus replacement with a new tank; those are different jobs with different prices.
- Soil work: sampling, cleanup and restoration if contamination is found.
- Who does the work: the company's own crew or subcontractors, and whether disposal and documentation are included.
- Timing: routine service versus emergency service for a leaking tank, which companies price differently.
What a written quote should itemize
- Exact scope: removal, abandonment, or removal plus replacement, and which parts of the job are included.
- How the price is calculated: by job, by tank size, or as a flat scope price, and what would change it.
- Permits: which county notices and permits are needed, who obtains them, and whether public fees are included.
- Soil testing: whether sampling is included, and what happens if contamination is found.
- Who does the work: the company's own crew or subcontractors.
- Total price and what would change it: extra work found during removal, added parts, or added excavation and cleanup.
Ask every company the same questions and compare itemized quotes, not headline figures. The quote-questions checklist on the Get quotes page is built for exactly that comparison.
