Oil Tank Sweep Specialists

Helping you find 
what others left behind


Oil Tanks and their potential liabilities are a major concern in residential real estate transactions. Leaking oil tank issue can impose a serious financial burden on homeowners. Therefore, it is highly recommended that every property purchaser performs an oil tank sweep to protect themselves from this open ended liability.

Scope of Work Step 1: Interior
A Hawkeye technician will generally start on the inside of the home looking for evidence of previous oil service by the heating system. The technician will then perform a detailed inspection of all interior basement walls that are accessible as well as crawl spaces (if accessible) and garages. The technician is looking for evidence of previous oil service generally indicated by copper fuel lines, trenching towards the furnace area or patching of basement walls.

Step 2: Exterior
The technician will perform a visual inspection of the outside of the home looking for evidence of oil tank piping along the exterior structure of the home.

Step 3: Sweep
A full property scan is conducted using a Schonstedt GA-52Cx Magnetometer. This equipment is capable of detecting metallic objects to a depth of 8' below grade. The technician will walk in a grid pattern scanning the property for the presence of oil tanks. If a large area reading is detected, it will be marked for further investigation. Hawkeye Services will generally scan the entire property. Unlike most of our competitors, our scans are not limited to a 30' radius around the home. Pricing is based on property size. Hawkeye services prides itself on accuracy and thoroughness. Therefore, we request that all large metal objects be moved off the property prior to the sweep. These objects include: cars, boats, trailers, dumpsters, moving containers (PODS, etc.) or any other large objects that cannot be moved by our technician. If the property is not entirely clear of these objects, Hawkeye will exclude these areas from the sweep and it will be noted in the final report.

Step 4: Report
Hawkeye Guarantee and Piece of Mind Protection- Hawkeye Services stands behind our work. A report is issued on every tank sweep performed documenting our findings and is generally available next day. If no tank is located, Hawkeye will include in the report a guarantee. Hawkeye Guarantee: If an oil tank is ever found while our client is the owner, Hawkeye will remove the tank at our cost. To stay within the guarantee limits, Hawkeye will be solely responsible for choosing the tank removal contractor and coordinating all services. Guarantee is limited to oil tank removal only and does not include costs for remediation associated with leaking oil tanks. Hawkeye Services holds insurance for General Liability, Errors and Omissions, Pollution Liability and Personal Injury.

Because Hawkeye Services conducts a comprehensive scan of an entire property, our pricing is directly linked to lot size.

Pricing is as follows:
Up to 1/2 Acre - $275
1/2 Acre to 2/3 acre - $325
2/3 to 1 Acre - $375
50' Radius Around Main House - $325
Over 1 Acre - Call for Pricing


Radon is an odorless and colorless naturally occurring radioactive gas that has been found in most soil types throughout New Jersey. It is estimated that radon gas contributes to 15,000 - 22,000 lung cancer related deaths annually. Radon is typically found in the lower level of homes and a build up to over the allowable state standard of 4.0 pCi/L is considered a health risk to property owners. Much like oil tank sweeps, radon testing is a vital component to the inspection process for property purchasers. Hawkeye Services holds a NJDEP certification as a Radon Measurement Technician (Certification #: MET13353). This certification allows Hawkeye to perform radon testing services to residential and commercial home buyers.

Radon Canister Pick Up Services
In working closely with licensed NJ Home Inspectors, Hawkeye Services provides radon canister pick-up services performed in conjunction with residential home inspections. If a canister pick-up is requested at the same time as an oil tank sweep, Hawkeye will perform this service at no charge. If a Home Inspector or Realtor requests a radon canister pick-up independent of an oil tank sweep, the cost for the pick-up is $35.00.

Ground Penetrating Radar (GPR) is a geophysical investigation used to image subsurface soils using radar pulses. High frequency radio waves are transmitted into the ground and bounce off buried objects which are then received by a receptor that then shows an image on a screen. GPR is generally performed in conjunction with Metallic Anomaly (MA) detection, Radio Frequency (RF) line tracing and Magnetic Field Anomaly (MFA) detection. GPR is a very accurate means to determining the presence/absence of possible Underground Storage Tanks (USTs) when excavation or other investigative options are not possible. Hawkeye Services provides Ground Penetrating Radar (GPR) services in cases where there are suspect tanks and the area above the suspect object is inaccessible due to asphalt, concrete, patios, etc...

In cases where a large area reading characteristic of an Underground Fuel Oil Storage Tank (UST) is detected, Hawkeye Services can provide Exploratory Excavation services. SCOPE OF WORK

Step 1: Paperwork Hawkeye will provide a written proposal to the client for the exploratory excavation services. Upon receipt of a signed contract with a deposit, Hawkeye will call in a utility markout on the property through NJ One Call.

Step 2: Excavation Work Once the utility markout is clear, Hawkeye Services will mobilize to the property to excavate the suspect area. If the area is under grass or soil, Hawkeye will attempt to remove the sod over the suspect area for re-use. If the suspect area is under a concrete or asphalt surface, the area will be saw cut with a concrete saw. Hawkeye will then hand excavate the suspect area to confirm/deny the presence of a UST. Upon completion, the excavated area will be backfilled to grade level. Restoration of the disturbed area is not conducted by Hawkeye personnel.

Step 3: Reporting A formal report will be issued to the homeowner indicating Hawkeye's findings. If a UST is located, Hawkeye can provide a trusted reference to a reputable oil tank removal contractor for tank removal work. If a UST is not located, Hawkeye will reflect these findings in the final report and a Hawkeye Guarantee will be issued to the client.
