|---|---|---|
| Single room | $300 – $800 | Walls only, basic prep, 2 coats |

The average cost to paint a full house interior in 2026 ranges from $2,000 to $6,000 for a standard three-bedroom home. This includes labor, primer, two coats of paint, and basic surface prep. Larger homes or those requiring extensive preparation, crown molding work, or premium paints can cost $8,000 or more.
Professional painters typically charge $300 to $800 per room depending on room size, ceiling height, and the amount of prep work required. A small bedroom may cost as little as $250, while a large living room with vaulted ceilings and multiple windows can exceed $1,000.
DIY painting costs roughly 50–70% less than hiring a professional since you eliminate labor costs, which make up about 70–85% of the total project price. However, professional painters deliver faster turnaround, cleaner lines, and better surface prep. For complex jobs with high ceilings, lead paint, or extensive repairs, hiring a pro often saves money in the long run by avoiding costly mistakes.
A professional painter can typically finish a standard 12×12 room in 4 to 6 hours including prep, priming, and two coats. DIY painters should expect to spend 8 to 12 hours on the same room. Large rooms, rooms requiring extensive prep, or color changes from dark to light can take significantly longer.
Exterior house painting costs between $3,000 and $8,000 for an average-sized home in 2026. Factors that drive cost include the home's square footage, number of stories, siding material, and whether power washing or scraping is needed. Multi-story homes may require scaffolding, adding $500 to $1,500 to the total.
Most interior walls should be repainted every 5 to 7 years under normal conditions. High-traffic areas like hallways, kitchens, and kids' rooms may need repainting every 3 to 4 years. Using higher-quality, washable paint can extend the life of your paint job and reduce long-term costs.
