Estimating an interior painting job breaks down into four steps: measuring the surface area, calculating material needs, estimating labor, and adding a markup for overhead and profit. For an accurate, professional quote, it is best to itemize costs rather than relying on rough estimates.
Some contractors use a rough base rate of $1.50 or $2.00 per square foot, some multiply 4 to 6 times the paint cost, some estimate the time the job will take and add it to an estimate of materials—and some may simply offer the lowest price to outbid the competition.
Interior painting labor costs $1 to $3 per square foot of coverage area or $3 to $7 per square foot of floor space. Painters charge $180 to $650 to paint a room or $20 to $50 per hour for smaller projects. Additional factors that influence labor costs are: Wall height.
The average cost to have a professional painter paint a 12x12 room ranges from $400 to $950 for labor and basic materials. If you are only painting the walls (excluding ceilings, trim, and doors), the price drops to the lower end, typically between $300 and $600.
Painting the interior of a 1000 sq ft house typically costs between $2,000 and $6,000. This translates to about $2 to $6 per square foot. The exact price depends heavily on prep work, whether ceilings and trim are included, and paint quality.
Your quote should be broken down into three sections:
Second should be the decorating work that will be carried out – including how many coats of paint will be applied to certain areas. Lastly should be details of the materials to be used, including the make of paints used.
Is Paint Usually Included in the Quote? So most professional painters do include the cost of paint in their estimates: Professional companies typically have accounts at local paint stores. Most professional painters also get a discount on paint from the larger paint brands like Benjamin Moore and Sherwin WIlliams.
Red is universally considered the hardest paint color to cover. Vibrant red pigments are highly transparent and inherently prone to bleeding through subsequent layers. Other notoriously difficult colors to cover include black, dark blue, dark green, and bright yellow.
For a professional painter, it takes 2 to 4 hours of active labor to paint the walls of a 12x12 room (one or two coats). However, factoring in taping, drying times between coats, and cleanup, the entire job usually takes 3 to 8 hours spread across a half-day to a full day.
For a standard 20x20 room, expect to charge between $𝟖𝟎𝟎 and $𝟐,𝟎𝟎𝟎+ depending on the scope of work. Professional interior painters typically charge $𝟐 𝐭𝐨 $𝟔 per square foot of floor area, or $𝟏.𝟓𝟎 𝐭𝐨 $𝟑.𝟓𝟎 per square foot of actual wall and ceiling surface area.
The best time to paint is generally spring and early fall. During these seasons, temperatures and humidity levels are moderate, allowing paint to adhere and dry properly. However, the ideal timing depends largely on whether you are painting inside or outside.
For a 24x36 painting, you should generally charge between $250 and $800+. Because this is a large, statement-sized canvas, your price should reflect the significant time, skill, and materials invested.
Bidding on a paint job begins with inspecting the site to measure the walls and find any damage or other problem areas. Use the square footage to find the amount of paint and other materials you'll need. Estimate the labor costs of the job and add your overhead and profit margin to the final estimate.
Home Size (Square Footage)
Typically, the average interior painting cost of a home is approximately $2.75 per square foot, falling within an average painting cost per square foot range of $2–$6. If you want to paint the trim and ceilings, the painting cost per square foot increases to $4.69.
