Underground Oil Tank Sweep in New Jersey
Underground Oil Tank Sweeps in New Jersey
Eagle Eye Inspections, LLC provides non-invasive underground oil tank sweeps for home buyers, sellers, and property owners throughout Northern New Jersey. This service is especially valuable for older properties and homes that were converted from oil heat to natural gas or another fuel source.
An abandoned underground heating oil tank may not be visible from the surface. Our sweep combines a visual evaluation with specialized magnetic detection equipment to look for evidence of a possible buried metallic tank or related components.
The oil tank sweep can be scheduled separately or added to a comprehensive New Jersey home inspection.
What Is an Underground Oil Tank Sweep?
An underground oil tank sweep is a non-invasive search of readily accessible areas of the property for indications of a buried metallic heating oil tank. The evaluation may identify a magnetic response, abandoned fill or vent piping, foundation penetrations, patched openings, or other visible evidence associated with a former oil-heating system.
A sweep does not involve excavation, opening a tank, testing its structural integrity, or collecting soil samples. If a suspicious underground metallic anomaly or possible tank is identified, further investigation by a qualified underground storage tank contractor may be recommended.
What Our Oil Tank Sweep Includes
- Visual evaluation of accessible exterior areas around the building
- Search for abandoned oil fill and vent pipes
- Evaluation of visible foundation walls for patched penetrations or other evidence of a former oil-heating system
- Inspection of accessible basement or utility areas for disconnected oil lines and related components
- Magnetic scanning of accessible portions of the property around the home
- Use of specialized detection equipment to help identify underground metallic anomalies
- Documentation of relevant observations and suspected locations
- A written report explaining the findings and recommended next steps
Professional Underground Detection Equipment
We use professional equipment, including a Schonstedt Maggie magnetic locator and Fisher TW-6 pipe and cable locator. These instruments help detect changes in the magnetic field and responses associated with buried ferrous metal.
Using more than one detection method helps us evaluate suspicious responses more carefully. However, detection equipment cannot independently determine whether every underground metallic response is an oil tank. Buried pipes, utility lines, reinforcing steel, construction debris, and other metal objects may produce similar indications.
Why an Oil Tank Sweep Is Important
Older New Jersey properties may have previously used heating oil even when the current system operates on natural gas. Records may be incomplete, and visible fill or vent pipes may have been removed during a prior conversion.
A buried tank that leaked may affect surrounding soil or groundwater and could lead to significant investigation, removal, and remediation expenses. Identifying evidence of a possible tank before purchasing a property gives the buyer an opportunity to request additional information or further evaluation before closing.
Information about unregulated residential heating oil tanks, closures, and remediation is available from the New Jersey Department of Environmental Protection.
What Happens If We Detect a Metallic Anomaly?
If the sweep identifies a response consistent with a possible underground metallic object, we document the approximate area and explain the finding in the report. Detection of an anomaly does not by itself confirm that an underground oil tank is present.
The next step may include reviewing municipal or property records and consulting a qualified underground storage tank contractor. The contractor may recommend additional investigation, excavation, tank closure or removal, integrity testing, or soil sampling depending on the circumstances.
Limitations of an Underground Oil Tank Sweep
An oil tank sweep is a visual and non-invasive evaluation and cannot guarantee that no underground tank exists. Detection may be limited by reinforced concrete, metal fencing, vehicles, stored materials, utilities, landscaping, inaccessible areas, excessive tank depth, property conditions, or interference from other buried metal.
The service does not include excavation, tank entry, pressure or integrity testing, environmental testing, soil sampling, laboratory analysis, tank removal, or remediation. These services must be performed by appropriately qualified contractors or environmental professionals.
Frequently Asked Questions
Is an oil tank sweep included in a standard home inspection?
No. An underground oil tank sweep is a specialized additional service that requires separate equipment and must be requested when scheduling the inspection.
Can you determine whether a buried tank is leaking?
No. A non-invasive sweep searches for evidence of a possible buried metallic object. Determining tank integrity or whether surrounding soil is contaminated requires additional evaluation by qualified tank and environmental professionals.
Can a property have an underground oil tank if it currently uses natural gas?
Yes. Some homes were converted from oil heat, and the former tank may have been removed, abandoned in place, or left underground. A current natural-gas system does not confirm what happened to the former oil tank.
Does a clean sweep guarantee that no tank is present?
No non-invasive detection method can provide an absolute guarantee. We report the conditions and responses observed in accessible areas at the time of the sweep and explain any limitations that affected the evaluation.
Should municipal records also be reviewed?
Yes. Permit, property, and tank-closure records may provide useful historical information. However, the absence of a record does not necessarily prove that a tank was never installed.
