Professional Oil Tank Removal & Decommissioning in Tacoma, WA

While not legally required, mortgage lenders and buyers typically require a decommissioning certificate or proof of removal. Undisclosed tanks can delay sales by weeks or result in price reductions of $10,000-$25,000. Most real estate agents strongly recommend addressing tank issues before listing to avoid complications during escrow.

Standard underground tank removal ranges from $2,500-$4,500. In-place decommissioning costs $1,800-$3,200. Above ground tank removal is $800-$1,500. Contaminated soil cleanup is additional and can range from $5,000-$25,000+ depending on the extent of contamination.

The exact cost depends on tank size, location (accessibility), soil conditions, and whether contamination is present. We provide free on-site estimates with detailed pricing.

A decommissioning certificate is official documentation from an ICC-certified specialist proving your tank was properly removed or filled in place according to Washington State regulations. It’s required for real estate transactions, provides legal protection from future liability, and gives buyers and lenders peace of mind. Without this certificate, you cannot prove the tank was properly decommissioned, which can jeopardize home sales.

The physical removal typically takes 1-2 days once we begin work. However, permitting through the Tacoma Fire Department takes 3-5 business days. If soil testing is required, lab results take another 1-2 weeks. Total timeline from initial contact to certificate issuance is usually 2-3 weeks for standard removals without contamination.

No. Washington State law requires ICC-certified decommissioners to perform the work and issue certificates. The Tacoma Fire Department requires a permit and will only approve work done by certified professionals. DIY removal won’t provide the required documentation for real estate transactions and could expose you to environmental liability. Additionally, improper removal can be dangerous due to residual fumes and contamination risks.

We handle contaminated soil remediation using excavation and bio-remediation methods. We’ll conduct soil testing to determine the extent of contamination (site characterization) and develop a cleanup plan approved by Pierce County Health Department.

We can also assist with insurance claims through the Pollution Liability Insurance Agency (PLIA) if you have coverage. Many homeowners insurance policies exclude oil tank leaks, but PLIA provides state-funded assistance for eligible properties. We’ll help navigate the claims process to minimize your out-of-pocket costs.

Look for these signs: fill pipes (2-inch diameter pipe near foundation), vent pipes, copper lines in basement/crawl space connected to old furnace, or historical use of oil heating in older homes (pre-1970s). Many homes in Tacoma neighborhoods like North End and Stadium District have abandoned tanks.

If you suspect a tank but can’t locate it, we offer professional tank locating services using ground penetrating radar (GPR) and metal detection. This is especially important if you’re planning a home sale, as hidden tanks discovered during buyer inspections can derail transactions.

A permit is required before decommissioning any residential heating oil tank. The work must be performed or directly supervised by an individual certified by the International Code Council (ICC) as an Underground Storage Tank Decommissioner. The contractor must maintain the permit on-site during work.

Upon completion, the ICC-certified decommissioner issues a certificate that gets filed with the Tacoma Fire Department. This certificate becomes part of the property records and is required documentation for real estate transactions. We handle all permitting and certification paperwork for you, ensuring full compliance with local and state regulations.
