The average cost to paint a 3000 sq ft house depends on factors such as paint quality, labor rates, the number of coats, and the condition of the walls. On average, homeowners can expect to spend between $4,500 and $10,000 for a complete interior or exterior paint job. Premium paints, detailed trim work, and surface repairs can increase the final cost. Getting multiple estimates from experienced contractors is the best way to ensure fair pricing.
