Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1951. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The building immediately east of this property along NE 45th Street was occupied by Laurelhurst Cleaners, a dry cleaning operation, from 1951 through 1970. Chlorinated solvents released during those two decades of dry cleaning activity have migrated to the subject property, and halogenated solvent contamination has since been confirmed on-site. The property is enrolled in Washington's Standard Cleanup program and is awaiting active remediation; no cleanup work has yet commenced. 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.

Dry cleaning operations at Laurelhurst Cleaners began in 1951 — more than three decades before 1986, the year occurrence-based Commercial General Liability policies with no effective pollution exclusion stopped being the industry standard. The halogenated solvent contamination confirmed at this property is the product of a slow, ongoing subsurface release tied directly to those pre-1986 operations. The investigation and remediation costs this property now faces could plausibly be funded by historical carriers whose policies were in force during the years those solvents were being released next door.

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.
