When hiring a general contractor in New York, verify they have proper licensing through the state and local municipalities, plus current liability and workers compensation insurance. Check their Better Business Bureau rating and ask for recent references from similar projects in your area. A reliable contractor provides detailed written estimates, clear project timelines, and regular communication throughout the work. They should handle permits, coordinate subcontractors, and maintain clean, organized work sites. Red flags include door-to-door solicitation, requests for large upfront payments, or contractors who can’t provide local references and proof of insurance.
