What Does a Real Workers Comp Claim Look Like for This California Class?
A window installer drops a large dual-pane window unit while installing it on a second-floor bedroom in a Sacramento new home — severe lacerations to hands and forearms, tendon repair surgery, and permanent partial disability in California can result in $90,000+ in workers comp costs. California's DWC rates finger and hand lacerations with tendon involvement at 5–20% PD depending on which fingers are affected.
Why Does a PEO Make Sense for California Workers Comp in This Class?
California door and window contractors benefit significantly from PEO group programs because their injury frequency is moderate but their claim severity — driven by glass-related lacerations — is high. Standard carriers often surcharge window contractors after a single severe glass injury. PEO group programs absorb individual claim volatility within the group's broader loss experience, providing stable pricing for contractors with clean records.
CA Rate Context
At $6.13/100, California door and window installation rates are moderate, reflecting the cut risk from glass handling and the back strain of heavy window unit installation. California's Title 24 energy efficiency requirements have driven a significant increase in window replacement work across the state, increasing the volume of window installation claims and contributing to the gradual rate increases seen over the past 5 years.
