Frequently Asked Questions

How much does it cost to paint a house interior in 2026?

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.

How much do painters charge per room?

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.

Is it cheaper to paint yourself or hire a pro?

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.

How long does it take to paint a room?

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.

How much does exterior house painting cost?

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.

How often should you repaint interior walls?

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.
