How to Estimate Painting Costs
Painting costs depend on square footage, number of coats, paint quality, and whether the job is interior or exterior. One gallon of paint typically covers about 350 square feet per coat. Most jobs require 2 coats for proper coverage.
Labor rates average $2-3 per square foot for interior work and $3-4 for exterior work. Exterior work costs more due to preparation requirements (power washing, scraping, priming) and the need for weather-resistant materials.
Additional costs may include primer (if changing colors dramatically), repairs to drywall or siding, caulking, tape, drop cloths, and equipment rental. For DIY projects, you will save on labor but should budget for supplies and equipment.
