About this guide

Long Island Oil Tank Guide is an independent, hand-verified directory of oil tank removal and abandonment companies serving Long Island, New York. It was built from a Phase 2 research file dated 2026-11-03, company by company, from each company's own website, and the 20 companies were approved one by one in review on 2026-11-03.

How listings were verified

• A company's own website beats directories whenever they conflict. Directory phone numbers, addresses and license numbers were deliberately not used where they differed from the company's own site.
• License numbers appear only where the company's own website publishes one. None of the 20 companies in this guide publishes a license number on its own website. The rest publish only a claim of being licensed and insured, without a number, or publish no license mention at all. A waste-transport permit under Part 364 is not a tank-removal license, and a Design Professional Corporation registration is not a tank-removal license either.
• Ratings appear only where the research file records one from the company's own site, with source and count where given. Only 1 of the 20 companies in this guide publishes a rating with a review count on its own website: Long Island Oil Tank Service, with a conflict noted between two sections of its own site.
• Prices appear only where a company publishes one on its own website. No company in this guide publishes a fixed tank-removal price. Ranges, averages, discounts, coupons and guarantees found on company sites are quoted in the cost guide, labeled as such, never as fixed prices for every home. Public county and municipal fees are labeled as public fees, never as company prices. Third-party national averages quoted on a company page are labeled as third-party averages, never as that company's prices.
• Companies that publish no street address on their own site are marked as such. No address was invented for them. 5 of the 20 companies in this guide are service-area companies.
• Company types are labeled. Some companies in this guide are tank specialists on their own site; others are environmental firms, general HVAC and plumbing firms, general fuel companies, or conversion-only companies, and the profile states that plainly. One entry is abandonment only, clearly labeled, and is not a verified removal company.

Featured listings

Featured listings are currently off for every company in this guide. No company paid for placement, and no company is marked as featured in the data. If a featured listing ever appears in future, it will be clearly labeled as a paid placement and will not change the verified facts in the profile. A featured label is never a quality endorsement.

Service-area companies

A service-area company serves Long Island but publishes no street address on its own site. Those companies are marked as service-area companies in this guide.

Corrections
