Exterior commercial painting typically costs 20-30% more than interior work due to additional prep requirements, weather protection needs, and specialized materials. Exterior projects require pressure washing, extensive surface prep, and weather-resistant coatings.
Interior projects focus on surface preparation, primer application, and finish coats with standard commercial-grade paints. The controlled environment allows for more predictable scheduling and material usage.
Factors affecting both include square footage, surface condition, paint quality, and project complexity. You’ll receive separate line items for each aspect, so you understand exactly what drives the cost.
