Oil Tank Removal & Environmental Cleanup in Sammamish, WA

If your property has an old oil tank, especially one underground, it’s important to consider having it removed. These tanks were once common for storing heating oil, but over time, they can rust and leak without any obvious signs. Leaks lead to soil and groundwater contamination, which can be expensive to clean up and harmful to the environment. Besides decreasing your property’s value, a leaking tank can also make it harder to sell or insure your property.


Removing an oil tank isn't exactly something you'd want to try doing yourself. Usually, professionals have special equipment that helps them locate and carefully excavate the tank without messing up the surrounding area. But removing the tank is just one part of the process. Environmental cleanup is just as important.


Environmental cleanup plays a critical role in protecting your property and the environment. After the tank is removed, experts check the surrounding soil and groundwater for any signs of contamination. If they find pollution, they get to work removing the contaminated soil immediately, treating the contaminated water, and making sure everything is safe again.


Professionals follow strict environmental regulations throughout the process, disposing of materials responsibly and minimizing any risk to your property and the community. Hiring experienced professionals protects your property, avoids costly future damage, and helps keep your environment safe and healthy. If you suspect an old oil tank on your property, don’t wait. A professional assessment and cleanup can help you save time, money, and reduce stress in the future.
