How long does it take to paint the inside of a house?

Quick answerHow long interior painting takes depends on the number and size of the rooms, how much prep the walls need, whether trim and doors are included and the drying time between coats. A single room can often be done in a day, and a whole house usually takes several days.

Nobody wants painters in their home longer than necessary, and nobody wants a rushed job either. Timelines come from a few clear factors.

Key takeaways
  • Rooms and size set the base
  • Prep adds time but protects the finish
  • Trim and doors take longer than walls
  • Drying time can’t be hurried
  • Ask for a timeline in writing

Rooms and ceiling height

More rooms and bigger rooms mean more surface. Tall walls and open stairwells slow things down because they need extra equipment and care. A house with ten ordinary rooms isn’t the same job as one with a two-storey entry.

Prep time

Filling cracks, sanding, cleaning and taping can take as long as painting. In an older house with many layers of paint, prep can take longer than the painting itself. It’s worth every hour, because paint over poor prep fails early.

Trim, doors and detail

Trim, baseboards, doors and frames are slow work, because they need careful cutting in and several coats. If you include them, expect the job to take noticeably longer than walls and ceilings alone.

Drying and recoating

Each coat has to dry before the next goes on, and the time depends on the paint, the temperature and the humidity. A good painter plans the order of the rooms so work continues in one room while another dries.

Getting a realistic timeline

Ask for a start date and a finish date in writing, and ask what could change them. We confirm a timeline when we confirm your price in person. You can start by pricing your rooms with our online estimate.

Quick questions

Can painters finish a house in a day?

A single small room can often be done in a day. A whole house takes longer, and rushing the prep or the drying time usually shows in the finish.

Does cold weather slow interior painting?

It can. Paint needs a minimum room temperature to dry properly, and cold rooms dry slowly. Our winter guide explains how to plan for it.
