What Affects Painting Cost Most
- Surface condition: Extensive prep (scraping, patching, priming) adds 30–60% to cost
- Number of colors: Multiple colors, trim contrasts, and accent walls add cost
- Ceiling height: Above 9 feet requires scaffolding — adds 15–30%
- Paint quality: Premium paint ($50–$70/gallon) vs. budget ($25–$35/gallon) — professional painters often use premium for better coverage and durability
DIY vs. Professional
Interior rooms are very accessible for DIY — particularly bedrooms and living areas on a single story. Rolling walls is straightforward; cutting in edges and painting trim takes practice. Exterior painting involves height, surface preparation, and weather timing — hire professionals for anything above single-story. Professional exterior painting includes pressure washing and prep that significantly impacts longevity.

Frequently Asked Questions
How much paint do I need per room?
One gallon covers approximately 350–400 sq ft with one coat. For a 12×12 bedroom with 8ft ceilings: (4 walls × 12ft × 8ft) = 384 sq ft ÷ 350 = 1.1 gallons per coat. Two coats = ~2.5 gallons accounting for waste. Subtract large window and door areas. Always buy slightly more than calculated — sheen matching from different batches is difficult.
What is the lifespan of exterior paint?
Quality exterior paint properly applied lasts 7–12 years in most climates. South-facing walls and areas with intense sun exposure fade and fail faster. Moisture is the primary enemy — ensure caulking is intact around all windows, doors, and trim before painting to prevent premature paint failure.
