Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1977. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

The Cleaning Shoppe dry cleaning facility began operating at this Renton property in 1977, with a PCE-based dry cleaning unit installed in 1978. Remediation under the Voluntary Cleanup Program included a Soil Vapor Extraction system operated for nine months in 2018–2019, excavation of 7,140 tons of PCE-impacted soil to a depth of 17 feet in 2021, installation of a 20-mil impermeable vapor barrier in 2021–2022, and four quarters of post-remediation groundwater monitoring completed in 2023–2024. The site has since achieved No Further Action status. 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.

The PCE contamination at this property traces directly to dry cleaning operations that began in 1977 and 1978 — nearly a decade before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. The scale of remediation required here — nearly 7,200 tons of excavated soil, a vapor extraction campaign, a permanent vapor barrier, and multi-year groundwater monitoring — reflects the full cost trail of a slow subsurface release tied to those pre-1986 operations. Historical carriers who issued CGL coverage during the facility's active dry cleaning years may bear liability for the costs already incurred to reach No Further Action.

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.
