General Contractors in Indiana are not required to carry general liability insurance. It is always a good practice to only hire contractors with active liability and workers' compensation insurance policies. Request a copy of each certificate for your records before the project starts.

Indiana has a Plumbers Recovery fund to protect consumers from faulty workmanship, or damages incurred during plumbing related projects.

Due to Indianas minimal regulation regarding contractor licensing, consumers should be extra vigilant when hiring contractors, check on BuildZoom for customer reviews, and permit history as indicators of quality businesses.
