Bonding and insurance are two different things, but ideally you want a contractor who has both. Think of bonding as protection once the job is complete and insurance as protection while the work is going on. When you choose a bonded contractor, you're protecting yourself in case he fails to pay subcontractors or just plain does a terrible job. If your contractor isn't bonded and flakes on something like this, you're the one who foots the bill. The contractor's insurance covers you for on-site problems, like an injured worker who otherwise might sue you for medical costs or damaged property that you'd have to replace out of your own pocket.
