Oil Tank Removal & Environmental Cleanup in Kent, WA

Cost varies widely in Kent, WA depending on tank size, location (basement vs. yard), soil contamination, access, required testing, and disposal fees. A simple, accessible 275–330 gallon heating-oil tank with no contamination might be on the lower end, while underground tanks or ones requiring remediation jump the price. Always ask for an itemized quote from Envirotank that separates removal, testing, excavation, disposal, and site restoration so there are no surprises and you can compare apples-to-apples bids.

Typical removals in Kent, WA can be completed in a single day for an aboveground tank with easy access and no contamination. Underground tanks or those requiring soil testing, permits, excavation, and remediation can take several days to weeks. Seasonal weather, permitting, and disposal facility schedules also affect timing. Envirotank can give a project timeline after a site visit — always plan for testing turnaround time and potential remediation to avoid being caught off-guard.

Many jurisdictions require permits for underground tank removals and sometimes for aboveground tanks if excavation or disposal routes are affected. In Kent, WA, local code and county health/environment departments determine permitting. Envirotank typically helps identify required permits and can either secure them or guide you through the process. Don’t assume no permit is needed — failing to obtain required permits can delay your project or lead to fines and problems during property transactions.

Soil testing is commonly required for underground tanks and any tank with signs of leakage. In Kent, WA, environmental rules and prospective buyer/lender requirements often mandate testing. Even if testing isn’t strictly required, it’s prudent — a clean test provides documentation for future property sales and protects you from liability. Envirotank usually recommends initial screening and will perform or coordinate soil sampling if there’s any suspicion of contamination.

Yes — Envirotank provides both tank removal and remediation services. If contamination is detected during soil tests in Kent, WA, remediation may include excavation and disposal of contaminated soil, on-site treatment, or monitored natural recovery depending on contamination extent. They’ll provide a remediation plan, cost estimate, and regulatory paperwork. Early detection reduces overall cost and complexity, so prioritize testing at the time of removal to avoid compounding issues.

Removing a tank and providing clean soil documentation can actually improve your property’s marketability in Kent, WA. Lenders and buyers often require proof that tanks were removed properly and that any contamination was addressed. Conversely, an abandoned or undocumented tank can delay escrow or trigger expensive inspections. Envirotank can produce removal reports, chain-of-custody for samples, and remediation documentation to satisfy lenders, title companies, and buyers.

Risks include groundwater contact with petroleum, vapors entering the home, and physical hazards during excavation. Proper procedures—like using trained technicians, vapour monitoring, spill prevention, and secure disposal—minimize risks. For Kent, WA properties with basements adjacent to tanks, vapour intrusion can be a concern; Envirotank uses best practices such as air monitoring and containment to protect occupants. Ask for the crew’s safety plan and whether temporary relocation is advised for sensitive occupants.

Yes—if a tank leaks, petroleum can migrate through soil and potentially affect neighboring properties or shallow groundwater wells in Kent, WA. The risk depends on soil type, slope, depth to groundwater, and time since leakage. Prompt removal and testing reduce spread. Envirotank will assess migration risk and, if necessary, recommend broader sampling. Early intervention not only mitigates environmental harm but can also reduce your liability to neighbors and local authorities.

Used oil and contaminated soil must go to licensed facilities. In Kent, WA, Envirotank will arrange transportation to approved disposal or treatment facilities and provide manifests and disposal receipts. Proper chain-of-custody documentation is critical for regulatory compliance and for buyers or lenders. Ask upfront how Envirotank documents disposal, the facilities they use, and whether any salvageable heating-oil is reclaimed — this transparency helps with auditing and future property transfers.

In some areas there are cleanup funds, low-interest loans, or tax incentives for environmental remediation—but availability changes over time. For Kent, WA homeowners, it’s worth asking Envirotank to check recent local and state programs (e.g., county environmental funds or state petroleum cleanup assistance). Even if no direct grant exists, properly documented removal can prevent costly future liabilities and may qualify you for incentives tied to brownfield cleanup or property redevelopment.
