Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1906. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This multi-parcel Seattle property hosted dye works and dry cleaning operations on at least two parcels prior to the 1960s, with buildings dating to as early as 1906 and historical records placing industrial use in the late 1800s. Operations involved petroleum products, solvents, and other chemicals associated with dye works and dry cleaning, along with a 300-gallon on-site gasoline tank documented in 1949 and heating oil systems in use during the property's industrial era. Adjacent properties sharing the site's contamination footprint have completed cleanup under Ecology oversight; the Tritell LLC Parking Lot has carried confirmed soil and groundwater contamination since 1997 and remains awaiting cleanup. 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.

Dye works and dry cleaning operations using petroleum products and solvents were conducted at this property for decades before 1986, the threshold year after which occurrence-based Commercial General Liability policies began routinely excluding pollution claims. The contamination identified across multiple parcels — tied to historical solvent and fuel use stretching back at least to the early twentieth century — is precisely the class of slow-onset environmental release those pre-1986 policies were written to cover. Historical carriers who issued CGL policies to operators during that long pre-1986 window may bear liability for investigation, remediation design, and cleanup costs that are only now being formally addressed.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

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 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
