What painting costs

  • Interior painting in the DMV typically runs $200 to $600 per room, depending on ceiling height, prep work, and finish quality. — Source: Make It Livable pricing data (DMV) (2026)
  • Labor accounts for roughly 70–85% of the cost of a professional paint job; the paint itself is the minor line item. — Source: Painting Contractors Association (PCA) (2024)
  • Prep work — patching, sanding, caulking, priming — is the single biggest quality (and price) differentiator between painting bids. — Source: Painting Contractors Association (PCA) (2024)

Paint performance and coverage

  • One gallon of paint covers roughly 350 to 400 square feet per coat on smooth, primed surfaces. — Source: Manufacturer specifications (Sherwin-Williams, Behr) (2025)
  • Interior wall paint typically lasts 5 to 10 years before needing a refresh; high-traffic areas and low-quality paint shorten that. — Source: Manufacturer guidance (2025)
  • Exterior paint lasts roughly 5 to 10 years depending on substrate — shortest on wood siding, longest on fiber cement and brick. — Source: Manufacturer guidance (2025)
  • Americans purchase on the order of 800 million-plus gallons of architectural coatings per year. — Source: American Coatings Association (2023)
  • Low- and zero-VOC paints have gone from niche to the default for major brands over the past decade, driven by EPA rules and consumer demand. — Source: American Coatings Association / EPA (2024)

Common questions

How much does it cost to paint a room?

In the DC/Maryland/Virginia market, $200 to $600 per room is typical for professional interior painting — walls, standard prep, two coats. Tall ceilings, heavy repair work, trim-and-door packages, and premium paints push it higher.

Why do painting quotes vary so much?

Prep work. A low bid often means minimal patching, no priming, and one heavy coat; a high bid may include skim coating, full priming, and two finish coats. Ask every painter to itemize prep — it's where the real difference lives.
