THE MATH
Exterior painting formula
Total cost = area × (paint price + labor)Exterior painting is priced per square foot and includes the paint plus labor: power washing, scraping, caulking, priming and application. A full repaint with prep costs more than a simple touch-up coat.
PRACTICAL EXAMPLE
A 1,500 sq ft exterior
1,500 sq ft × ($1.50/sq ft paint + $2.50/sq ft labor) = $6,000.
FAQ
Frequently asked questions
How much does it cost to paint a house exterior?
Most 1,500 sq ft homes run $2,500–$6,500. The range depends on paint quality, prep needed and the number of stories.
Should I use oil or latex paint?
100% acrylic latex is the standard for exteriors — it flexes with temperature changes, resists fading and cleans up with water.
How long does exterior paint last?
Quality paint lasts 5-10 years on siding and 3-7 years on trim, depending on sun exposure and climate.
