Look for contractors with extensive experience completing projects similar to yours. Ask about their typical job size, specialty areas, and design-build capabilities if needed. More experience brings knowledge and efficiency.
Verify they are properly trained and licensed for the work needed. Specialty certifications show expertise like LEED for green buildings or aging-in-place for accessibility. Membership in reputable home builder associations also indicates dedication.
Request photos/examples of previous work that demonstrate mastery of the style and features you want. A portfolio shows the quality and capabilities of their team.
