Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1979. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

Woodgate Cleaners operated as a dry cleaning facility at this Woodinville property from 1979 to 2022, using tetrachloroethylene (PCE) throughout its four-plus decades of operation. Cleanup under the Voluntary Cleanup Program included excavation and off-site disposal of 170 tons of PCE-contaminated soil and 7.3 tons of investigation-derived waste, along with ozone sparging, air sparging, and dewatering of more than 1.3 million gallons of water between 2022 and 2024. The site has reached No Further Action status, subject to ongoing monitoring, periodic reviews, an Environmental Covenant, and the future installation of a Vapor Intrusion Mitigation System for any residential buildings constructed on the property. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.

Why Historical Insurance Policies May Be Accessible

Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.

PCE contamination at this property traces to dry cleaning operations that began in 1979 — seven years before the 1986 threshold after which occurrence-based Commercial General Liability policies routinely incorporated enforceable pollution exclusions. The documented remediation expenditures here — soil excavation, millions of gallons of groundwater treatment, vapor intrusion controls, and long-term monitoring obligations — represent costs tied directly to releases during that pre-1986 window of exposure. Historical carriers who issued CGL policies to Woodgate Cleaners during those early operating years may still be obligated to recover those cleanup costs.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
