The Washington Supreme Court reversed the Court of Appeals' decision that the ensuing loss provision provided coverage for a deck that collapsed due to rot and decay. Sprague v. Safeco Ins. Co. of Am., 2012 Wash. LEXIS 375 (Wash. May 17, 2012). Our prior post on the Court of Appeals' decision is here.
The Sprague's home had a deck supported by six “fin walls.” The fin walls were encased in a foam and stucco coating. Twenty years after they purchased the home, it was discovered that the fin walls were in an advanced state of decay. Engineers discovered that construction defects caused the supports to rot. The deck was in danger of imminent collapse.
Safeco denied coverage. The all-risk policy did not exclude collapse, but did exclude coverage for losses causes by mold, wet or dry rot.
