One job, many small decisions
Repainting a whole interior sounds like one project, but a painter prices it as dozens of small ones: each room, each ceiling, each run of trim, each door. Two bids for the same house can land far apart because one painter counted the closets and the stairwell and the other didn't. This guide walks through what moves the price, so you can see why, and so you can compare proposals on the same terms. It quotes no prices; only a painter who has seen the rooms can do that.
Counting the surfaces
The basic measure is surface area, but it's broken up by type, because each type takes a different amount of time:
- Walls are the largest area and usually the quickest per square foot.
- Ceilings are slower, because the painter is working overhead, and they often need a flat ceiling paint in a different color from the walls.
- Trim such as baseboards, casings and crown molding is priced by length or by room, and it's slow: every edge is cut by hand.
- Doors are counted one by one, with both faces and the edges. Paneled doors take longer than flat ones.
- Closets, stairwells and hallways are small but awkward, and easy to leave out.
When you compare bids, check that each one lists the same rooms and the same surfaces in each room.
The condition of the walls
Prep time is where interior bids diverge most. Nail pops, cracks at drywall seams, dents, old anchors and holes from pictures all need filling, sanding and spot-priming. Water stains and smoke need a stain-blocking primer. Glossy old paint needs scuffing. A house that has been lived in for years usually needs more of this than people expect, and the more there is, the more the job costs. Our drywall repair and surface preparation guide shows what each repair involves.
Color changes and coats
Repainting a room the same color, or a similar one, may be done in fewer coats. Going from dark to light, or light to a deep color, can need a tinted primer and extra finish coats. Each added coat adds labor and paint. A good proposal states how many coats each surface gets.
Heights and access
Standard ceilings are done from the floor or a short ladder. Vaulted ceilings, open stairwells and two-storey entries need taller ladders, planks or scaffolding, and more time to set up and move. Expect them to be priced separately.
Furniture and protection
Moving furniture, covering floors, removing switch plates and masking fixtures all take time. You can lower that part of the cost by clearing rooms yourself, but agree on it in writing so nobody's surprised on the first morning.
The product class
Paint lines range from contractor grades to premium grades, and from flat to gloss. Better paints usually cover and wear better, which can mean fewer coats and fewer touch-ups later. Ask which product line and sheen the painter is quoting for walls, ceilings and trim. Our paint sheens and finishes guide explains the choices.
Older homes and lead-safe work
EPA says approximately three-quarters of U.S. homes built before 1978 still contain some lead-based paint, and that any renovation, repair or painting project in a pre-1978 home with lead-based paint can easily create dangerous lead dust.
On a pre-1978 home, sanding and scraping inside call for containment: sealed doorways, covered floors and vents, wet methods and careful cleanup. All of that adds time and materials, and it belongs in the price. Ask the painter how they plan to handle it.
Painting while the heat is on
NOAA's engineering weather data for Provo lists about 5,083 heating degree days and 937 cooling degree days in an average year (base 65°F).
Heating degree days measure how much heating a place needs over a year. For an interior repaint, a large heating figure points to rooms that are often painted with the windows shut. Drying slows without fresh air, and a crew may need fans or more time between coats. Ask whether the schedule allows for that.
What a clear proposal includes
- every room and surface, with ceilings, trim and doors listed;
- repairs and priming, room by room;
- products, sheens and coats;
- who moves furniture and how floors are protected;
- containment and cleanup on pre-1978 homes.
