The U.S. District Court found that the contractor was entitled to a defense in the underlying state court action. Pa. Nat'l Mut. Cas. Ins. Co. v. Zonko Builders, 2021 U.S. Dist. LEXIS 168855 (D. Del. Sept. 7, 2021).

Zonko was the general contractor for building the Salt Meadows Townhomes Condominium. This included supervising subcontractors in the installation of siding, house wrap, and flashing in five buildings between 2005 and 2007. In 2016, Salt Meadows and its individual members ("Association") found property damage in the condominiums.

The Association sued Zonko in state court, alleged that resulting damages included drywall damage in ceilings or walls, flooring and carpet, water damage around window trim, rot on window frames, incorrect flashing around roofs and windows, possible ridge vent leaks, and possible foundation issues.
