These tanks are often well past their useful service life and have often leaked. Buying a contaminated property means you are responsible for the cleanup costs even though you may have no prior knowledge of the contamination. Cleanups (remediations) are costly – ranging from $5,000 to $100,000.00.  These tank leaks are often excluded from insurance policies, so you the homeowners will not pay for the loss and you the homeowner wind up paying for someone else problem.   # Tank Sweep Questions # Call our Office Monday to Friday Eastern Standard Time # 888-301-1050   **Did You Know?** 1. Oil heat was popular from the 1940s into the 1990s. 2. A typical life span of an oil tank is similar to a roof.  Meaning if a roof was replaced so should a tank. 3. Many oil tanks were abandoned with oil in them when homes were converted to from oil to gas.   So abandoned tanks were just that abandoned. 4. Some homeowners have removed tank piping to disguise a tank location to avoid having to deal with the tank themselves.  Tank sweeps can find these tanks. 5. Tank Sweeps with GPR (Ground Penetrating Radar) are the most though way to scan for a tank.  Tank Sweeps using only metal detectors can give false information as the metal detector is subject to interference from metal siding, mesh in stucco, metal in concrete, buried metal pipes, and ferrous present in the ground. 6. Home inspections do not include Oil Tank Sweeps as part of their inspection.                                                                            **Curren Environmental has over 25 ****years of experience**** with oil tanks and that translates into the performance of experienced and thorough Tank Sweeps.  Our technicians have years of knowledge in dealing with oil tanks, including**: - Knowing of how oil tank systems work. - What piping to look for when performing a tank sweep. - The difference between single and supply and return oil lines. - Direct fill and remote fill bungs. - Typical and unusual locations of buried oil tanks. - Geophysical signature interpretation of buried tanks with GPR [More About Tank Sweeps](https://www.currenenvironmental.com/More%20About%20Tank%20Sweeps)   ![tank sweep with GPR](https://www.currenenvironmental.com/hs-fs/hubfs/tank%20sweep%20with%20GPR.jpg?width=4032&height=3024&name=tank%20sweep%20with%20GPR.jpg)   ![tank sweeps](https://www.currenenvironmental.com/hs-fs/hubfs/Curren%20Equipment-1.jpg?width=4032&height=3024&name=Curren%20Equipment-1.jpg)   [LSRP ](https://www.currenenvironmental.com/njdep-lsrp-licensed-site-remediation-professional/)| [ISRA ](https://www.currenenvironmental.com/NJDEP-ISRA-Industrial-Site-Recovery-Act-Process-/)| [Services](https://www.currenenvironmental.com/services/remediation/remediation-overview/) | [Tanks](https://www.currenenvironmental.com/services/ust-removal/commercial-tank-removal/) | [Remediation](https://www.currenenvironmental.com/services/remediation/remediation-overview/) | [Real Estate](https://www.currenenvironmental.com/Environmental-Issues-in-Residential-Real-Estate) | [Mold Remediation ](https://www.currenenvironmental.com/mold-remediation--/)| [Blog](https://www.currenenvironmental.com/blog/) | [Contact](https://www.currenenvironmental.com/contact-us/) | [Foam Tank Filling](https://www.currenenvironmental.com/foam-tank-filling) | [Insurance Restoration](https://www.currenenvironmental.com/insurance-restoration/) |[UST AST Closure](https://www.currenenvironmental.com/ust-ast-closure/) Curren Environmental is your environmental services company servicing Delaware, New Jersey and Pennsylvania. *Nothing on this web page, or anywhere on this website, is to be construed as giving legal advice, nor is it intended to replace the counsel of your own legal and financial advisors.   The information supplied is intended to help make you more aware of issues that you should consider and then discuss with your own legal and financial advisors. * [*Privacy Policy.*](https://www.currenenvironmental.com/curren-environmental-privacy-policy) © 2026 Curren Environmental, Inc. - All Rights Reserved.
