Oil Tank Removal & Environmental Cleanup in Issaquah, WA

Oil tank removal and environmental cleanup are essential for maintaining property safety, preventing costly contamination, and supporting the long-term health of surrounding land and water. When outdated tanks begin to corrode, they can release fuel that spreads quietly through soil and groundwater, creating hazards that escalate if ignored. Addressing these issues responsibly reduces liability, prevents regulatory complications, and restores confidence in the stability of the site. By managing materials properly and following established environmental standards, these services help protect communities, safeguard resources, and keep properties in dependable working condition.


Hiring professionals for oil tank removal and environmental cleanup ensures that each phase of the process is completed with accuracy, regulatory understanding, and documented safety. Trained specialists can detect hidden concerns such as residual fuel, unstable excavation zones, or undocumented connections that untrained individuals might miss. Their expertise reduces the likelihood of secondary damage and keeps the project moving efficiently. Professional oversight also simplifies permitting, testing, disposal, and reporting requirements. By using qualified experts, property owners gain stronger protection, smoother real estate transitions, and confidence that environmental responsibilities have been fulfilled thoroughly and correctly.

Happy Customers in Issaquah, WA

We would like to recommend a very capable family-owned business called Envirotank. We had a polluted underground oil tank in a very challenging spot. Ross Agledal, owner, is a talented heavy equipment operator that can navigate tight places like he is on a dance floor. His command of an excavator is like an extension of his own limbs. His wife Melissa and son Evan work alongside to make a great team. His excavation work is meticulous, with tight coordination of sub-contractors, plumbers, inspections and soil testing all scheduled for maximum efficiency. The Envirotank team is hard to beat.

I hired Envirotank to pull a 500 gallon butted oil tank from my yard. They were timely, efficient, ery careful about the surrounding vegetation and they cleaned up thoroughly.  We're very happy with the work they did.

Ross and the rest of the Envirotank crew were a pleasure to work with. I’m so happy to have the old oil furnace gone (and tank) and also very pleased to have the leaked fuel / contaminated soil removed and backfilled with good clean fill.
