Who handles what
In Delaware, contractor complaints usually move through five channels. Start with the contractor in writing and preserve contracts, photos, payments, permits, insurance certificates, county inspection notes, and DELPROS screenshots before involving an agency. The Delaware Department of Justice Consumer Protection Unit handles deceptive trade practices, false credentials, deposit fraud, door-to-door pressure, and repeat patterns; it normally does not act as your private lawyer. Use the Delaware Division of Professional Regulation and DELPROS for electrical, plumbing, HVACR, home inspection, manufactured-home installation, and other licensed trade checks, and confirm construction contractor registration and local permits separately. BBB is a private marketplace channel, not a regulator, but a BBB complaint can create a dated public record. For insurance, use the Delaware Department of Insurance to understand how to verify a contractor's general-liability or workers' compensation certificate with the listed carrier or agent. Small claims in Delaware Justice of the Peace Court is commonly capped at $25,000. Escalate in this order: written demand, license and permit verification, DPR or local building complaint, state consumer complaint, BBB record, insurance verification, then small claims or counsel. Breach-of-written-contract claims are commonly 3 years. The mechanics-lien window tracked here is 120 days for residential planning under Del. Code tit. 25, ch. 27; treat any lien paper as urgent.
