In Utah, a Contractor with LRF refers to a licensed contractor who holds a License Recovery Fund (LRF) certificate. This fund is designed to protect consumers by providing financial compensation in cases where a licensed contractor fails to fulfill their contractual obligations or commits fraud. Contractors can apply for this designation to demonstrate their commitment to ethical practices and consumer protection in the construction industry.
Being licensed basically states that the contractor has the knowledge expected to perform the services indicated on the license.Being insured means that while he's doing the job you hired him to do, if he backs his truck into the wall of your garage or sets fire to your home, he has insurance that can pay for damages or to have it fixed.

Licensed
Generally, your state maintains a repository or data base of current contractors' licenses. You can also ask for proof of license. In this case, educate yourself about what to look for in the physical document.

Licensed tradies know what their licence covers and usually respects the rules (because if they don't obey them their licence will be revoked).
