What Is the Average Cost of Painting a House?

What Is the Average Cost of Painting a House?

Rodrigo Pereira Teixeira |

Painting your home is one of the most cost-effective ways to refresh its look and protect it from wear and tear. But how much should you expect to spend on a painting project? The answer depends on whether you’re painting inside or outside, the size of your home, the quality of paint, and whether you hire a professional or go the DIY route. Below, we answer the most common cost-related questions homeowners have.


1. What is the average cost to paint the interior of a home?

Interior painting typically costs between $2 and $6 per square foot, depending on the paint quality, number of coats, and surface preparation needed. For a standard 1,500 sq. ft. home, this means a range of $3,000–$9,000 if you hire a professional.


2. How much does it cost to paint the exterior of a house?

Exterior painting usually costs between $1.50 and $4 per square foot. On average, homeowners spend $4,000–$8,000 for a medium-sized home. Larger homes or those with complex architecture, multiple stories, or textured siding can cost more.


3. What factors affect the cost of painting?

  • Size of the home – more square footage means more labour and materials.

  • Surface condition – damaged or peeling surfaces require prep work.

  • Number of coats – dark-to-light transitions often require more coats.

  • Paint quality – premium, low-VOC, or specialty paints cost more but last longer.

  • Labour – professional rates vary depending on experience and region.

4. Is DIY painting cheaper than hiring a professional?

DIY painting saves on labour costs, but you’ll need to buy brushes, rollers, drop cloths, ladders, and high-quality paint. Mistakes or uneven finishes may require a pro to fix later, which adds cost. Hiring professionals ensures efficiency, safety, and a long-lasting finish. Submit our Painter Order Form to connect with trusted local painters.


5. How much should I budget for paint and supplies?

Paint alone typically costs $40–$90 per gallon, covering about 350–400 sq. ft. You’ll also need supplies like rollers, brushes, trays, tape, and drop cloths. Explore Randall’s paint collection for premium paints and painting tools.


6. How do I know if I need multiple coats?

  • Dark to light color changes often need 2–3 coats.

  • High-traffic areas like hallways and kitchens benefit from extra coverage.

  • Exteriors exposed to harsh weather may also need multiple layers for protection.

7. Are there hidden costs I should expect?

Yes, some additional costs may include:

  • Repairing drywall, cracks, or wood damage

  • Removing wallpaper or old finishes

  • Power washing or priming exterior surfaces

  • Moving furniture and cleanup
