The cost to paint the interior of a house is $1 to $3 per square foot of floor space or $1,300 to $6,300 for an average-size home. The average cost to paint a room is $300 to $1,000, depending on the size and complexity. Prices increase when including the ceilings, baseboards, and trim.

Interior painting is a cost-effective way to add value and boost home appeal. Interior painting has a 107% return on investment (ROI), while exterior painting has a 55% return on investment on average.

Interior walls need painting every three to seven years on average, depending on the room type, traffic and condition, and previous paint job. Ceilings need painting every 7 to 10 years, and baseboards and trim need repainting every 2 to 4 years.

Signs interior walls need painting:

• Paint is peeling, flaking, bubbling, cracking, faded, or chalky
• There are stains and mold on the walls
• The walls are damaged
• The last paint job was longer than 7 years ago
• You're tired of the current color
• You're selling the home and want to increase the appeal

Painting a room takes two to six hours on average. The time it takes to paint a room depends on the prep work, primer requirements, room size, if ceilings need painting, number of coats, and clean up.

Painting an entire house interior takes two to six days on average. The time it takes to paint a house interior depends on the home size, painting team size, prep work, number of coats, and clean up.

Interior house painters do not expect a tip. However, if they go above and beyond or spend more time than expected, a cold drink, hot lunch, or $10 to $20 tip is appreciated. Giving the painter a positive review on HomeGuide, Yelp, or Google is better than a tip.
