A homeowner-friendly explanation of the main factors that determine interior painting cost, from room size and paint quality to wall preparation, coats, ceilings, and additional surfaces.

Interior painting is more than simply applying paint to walls. The total cost depends on the condition of the existing surface, the preparation required, the paint selected, the number of coats, and the areas included in the project.
The type and quality of paint can have a significant effect on the total cost. Different rooms may also have different requirements.
Preparation is often overlooked when comparing painting prices.
Depending on the existing condition, preparation can involve:
Cleaning
Scraping loose paint
Sanding
Filling cracks
Putty application
Primer
Minor surface repairs
A smooth, well-prepared surface generally produces a better finish.
Painting labour depends on the size and complexity of the project and the amount of preparation involved.
The required number of coats depends on the existing surface, colour change, paint product, and desired finish.
When planning an interior painting project, decide whether the ceiling is included. If you are comparing quotations, make sure each quotation clearly states whether ceilings are part of the scope.
Doors, window frames, grills, and other surfaces may be priced separately. If you want these painted, include them when requesting a quote rather than assuming they are part of the wall-painting price.
