Between shipping delays, weather, and a smaller pool of licensed contractors, project timelines here run longer than mainland expectations almost as a rule. That's frustrating but normal, and usually not a legal problem, just an island reality worth planning around.
A contractor who takes a deposit, does little or no work, and then stops responding entirely is a different category of problem. That's not a delay. Depending on the amount and the circumstances, it can be breach of contract, and in some cases actual fraud, especially if there was never any real intention to complete the work.
Licensed contractors here are required to carry a contractor's license bond, specifically meant to provide some recovery for homeowners in exactly this situation. Filing a claim against that bond is a real, available option most homeowners don't know exists, separate from suing the contractor directly.
Small claims court is also a realistic path for smaller deposit amounts — no lawyer required, a real hearing, and a judge who looks at the actual contract and payment record rather than taking anyone's word for it.
A slow contractor is often just island life. A vanished one, with your money, is a legal situation with real paths forward, not something to just write off.
