When purchasing a home, there are various inspections and assessments to ensure that the property is in good condition. One important step, particularly in older homes, is an oil tank sweep. In this guide, we'll explore what oil tank sweeps entail, why they're essential, and what to do if an oil tank leak is discovered.
What is an Oil Tank Sweep?
An oil tank sweep, also known as an oil tank scan or oil tank search, is a comprehensive inspection conducted to detect the presence of buried or underground oil tanks on a property. These tanks were commonly used for heating homes before the widespread adoption of natural gas or electric heating systems.
During an oil tank sweep, a professional technician uses specialized equipment such as ground-penetrating radar (GPR) or metal detectors to scan the property for signs of underground oil tanks. If an oil tank is detected, further investigation may be necessary to determine its condition and whether it poses any risks to the property.
Why are Oil Tank Sweeps Important?
Oil tank sweeps are crucial for several reasons:
Environmental Protection: Abandoned or leaking oil tanks can pose significant environmental hazards, contaminating soil and groundwater with harmful substances like petroleum, heavy metals, and other pollutants.
Financial Liability: If an oil tank leak is discovered after purchasing a property, remediation costs can be substantial. Conducting an oil tank sweep helps buyers identify potential issues upfront and negotiate with sellers accordingly.
Property Value: Properties with undisclosed or unknown oil tanks may be less desirable to buyers, leading to difficulties in selling the home in the future. Knowing the condition of the property's oil tank(s) can help buyers make informed decisions and protect their investment.
Cost of Oil Tank Sweeps and Remediation
The cost of an oil tank sweep can vary depending on factors such as the size of the property, the type of equipment used, and the location. On average, oil tank sweeps typically range from $200 to $500, but prices may be higher in certain areas or for larger properties.
If an oil tank leak is detected during the sweep, remediation costs can be significant. The extent of remediation depends on factors such as the size of the leak, the extent of soil contamination, and local regulations. Remediation costs can range from a few thousand dollars to tens of thousands of dollars or more, depending on the severity of the contamination and the required cleanup measures.
It's important for buyers to factor potential remediation costs into their budget and negotiations when purchasing a property with an oil tank. Working with experienced professionals, such as environmental consultants and remediation specialists, can help buyers assess the situation and determine the best course of action.
Oil tank sweeps are a crucial step in the homebuying process, helping buyers identify potential environmental hazards and financial liabilities associated with buried or underground oil tanks. While the cost of an oil tank sweep is relatively modest compared to potential remediation costs, it can provide peace of mind and protect buyers from unexpected expenses down the road. Investing in an oil tank sweep is a wise decision for any homebuyer, particularly those purchasing older properties with a history of oil heating.
