Chimney Contractor Insurance in Washington State

Chimney contractors in Washington occupy a unique risk position where rooftop work intersects with fire safety, creating a liability profile that includes both immediate physical hazards and long-tail completed operations exposure that few other specialty trades face. Every chimney you sweep, reline, repair, or install is a component of a home's fire safety system, and if your work is deficient and a chimney fire results, the consequences — property destruction, bodily injury, or death — generate claims that can reach catastrophic levels.

The fire liability is the defining risk for chimney contractors. When you inspect a chimney and certify it as safe, or when you clean a flue and leave creosote buildup in an area you missed, you take on responsibility for the fire safety of that system until the next service. A chimney fire in Washington typically causes $20,000 to $150,000 in property damage if contained to the chimney and surrounding structure, but an uncontained fire that spreads to the rest of the home can generate total-loss claims exceeding $500,000. If occupants are injured or killed, the bodily injury component and wrongful death exposure can push the total into the millions. Your completed operations coverage is the critical protection here — these fires often occur weeks or months after your service visit.

Rooftop work is the other major hazard. Chimney contractors spend most of their working time on roofs — often steep-pitched residential roofs in the Pacific Northwest's wet conditions, where moss-covered shingles and rain-slicked surfaces create treacherous footing. Unlike roofers who typically work on new or stripped surfaces with safety systems already in place, chimney workers climb onto existing roofs of varying age and condition, often working alone on service calls. Falls from residential roofs are a leading cause of serious injury in the trades, and chimney workers face this exposure on every single job.

Washington requires chimney contractors to register with L&I and carry a $15,000 specialty contractor surety bond. The chimney industry also has voluntary certification through the Chimney Safety Institute of America (CSIA), and many insurance carriers offer lower rates for CSIA-certified contractors. Masonry chimney repair and relining work must comply with Washington State Building Code requirements, and any gas appliance venting work must meet mechanical code standards. The seasonal pattern of chimney work in Washington — with demand peaking in fall before heating season — creates concentrated exposure periods where crews work long hours to complete inspections and repairs before winter.
