What do "licensed," "bonded," and "insured" actually mean?
Licensed means Rockland County checked the contractor's work experience and insurance before letting them operate here. If a licensed contractor treats you badly, you can file a complaint with the county — real leverage you don't have with an unlicensed one.
Bonded means the contractor has a surety bond — money held by an insurance company that you may be able to claim if the contractor takes your deposit and doesn't finish, or the work fails. Not every licensed contractor is bonded; ask directly.
Insured means their insurance — not your homeowner's policy — pays if a worker is hurt or your property is damaged during the job. Ask to see a current certificate of insurance before work starts.
