Dry Cleaner cleanup site — Restorical Research
Montlake Apartments
2300 24th Ave E, Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1930. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Montlake Apartments property was constructed in 1914, and historical records document a dry cleaning business — "Montlake Dye Works - Clothes Pressers and Cleaners" — operating at this address as of 1930. Environmental investigation has identified tetrachloroethylene (PCE) and its breakdown product trichloroethylene (TCE) in soil and groundwater beneath the property, contamination directly linked to that historical dry cleaning use and recognized as an environmental condition under ASTM E1527-21 standards. The property is currently enrolled in Washington's Voluntary Cleanup Program, with active cleanup work not 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.

The PCE contamination at this property originated from dry cleaning operations conducted more than five decades before 1986, when occurrence-based Commercial General Liability policies were still the industry norm and lacked effective pollution exclusions. The slow, ongoing release of chlorinated solvents into soil and groundwater is precisely the contamination type those pre-1986 policies were written to cover. The investigation, remedial design, and cleanup costs now facing this property could plausibly be funded by historical carriers whose CGL policies were in effect during the decades when Montlake Dye Works was operating.

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.
