Pool Contractor Insurance in Washington State

Pool contractors in Washington operate in one of the highest-liability niches in residential construction, carrying exposure that spans nearly every trade discipline and extends indefinitely after the project is complete. Building a swimming pool involves excavation, structural concrete or fiberglass installation, plumbing, electrical, gas lines for heaters, and complex filtration and chemical treatment systems. Each of these components carries its own distinct liability: excavation creates utility strike and cave-in risk, plumbing creates water intrusion exposure, electrical work around water creates electrocution hazard, and gas connections create fire and carbon monoxide risk. No other residential trade combines this many high-risk activities into a single project.

The defining liability for pool contractors is drowning. Unlike virtually every other construction defect, which results in property damage claims, a pool-related failure can result in a death — most often of a child. If a pool barrier, gate latch, drain cover, or safety system you installed fails and contributes to a drowning, the resulting wrongful death claim will name you regardless of how many years have passed since construction. Pool-related wrongful death settlements routinely reach seven figures, and the emotional weight of these cases makes juries sympathetic to plaintiffs. Washington requires pool barriers under the International Swimming Pool and Spa Code (ISPSC) as adopted in the state building code, and failure to install code-compliant barriers is near-certain liability in any drowning case.

Chemical handling and water treatment systems create additional risk. Pool contractors who service and maintain pools handle muriatic acid, chlorine, and other hazardous chemicals that can cause chemical burns, respiratory injuries, and environmental contamination if mishandled. Improperly balanced pool water can cause skin and eye injuries to swimmers, and a malfunctioning chemical feed system can release dangerous concentrations of chlorine gas. These claims fall under both general liability and, in some cases, pollution liability coverage.

Washington's climate presents unique challenges for pool construction. The freeze-thaw cycles experienced in eastern Washington and at higher elevations can crack concrete pool shells, damage plumbing lines, and destroy equipment that was not properly winterized. Even in western Washington, the combination of heavy clay soils, high water tables, and seismic activity creates structural challenges that don't exist in sunbelt states where most pool industry practices were developed. A pool shell that cracks due to soil movement or frost heave generates a construction defect claim under RCW 64.50 that can cost tens of thousands of dollars to remediate. Operating a pool construction or service business in Washington without comprehensive insurance coverage is a risk no responsible contractor should take.
