A useful painting budget is a range with assumptions, not a single number detached from the house. In Ontario, labour, preparation, access and the surfaces included usually change the estimate more than the price printed on a can of paint.
Broad Canadian planning ranges for 2026
HomeStars’ June 2026 Canadian guides publish the following broad ranges:
| Project type | Published planning range |
|---|---|
| Single interior room | $400–$800 |
| Full interior, approximately 1,500–2,000 sq. ft. home | $2,000–$5,000 |
| Full interior, approximately 2,500–3,500 sq. ft. home | $4,000–$8,000 |
| Exterior repaint, approximately 1,500–2,000 sq. ft. home | $3,000–$8,000 |
| Interior walls only | $2–$4 per sq. ft. |
| Interior walls, ceilings and trim | $3–$5 per sq. ft. |
| Exterior painting | $3–$6 per sq. ft. |
These are broad national figures. They combine projects with different preparation standards, room counts, ceiling heights and definitions of “full interior.” A detailed Niagara quote may sit below, inside or above a published range.
Why square-foot prices are easy to misunderstand
A home’s floor area is not its paintable area. Two 1,800-square-foot houses can have very different quantities of wall, trim and ceiling. Open plans reduce some wall area; stairwells, vaulted ceilings, built-ins, doors and detailed millwork add labour without increasing the advertised floor area.
Before relying on a square-foot number, ask:
- Is the measurement based on floor area, wall area or coated surface area?
- Are ceilings, baseboards, doors, frames and closets included?
- How many colours and coats are assumed?
- What preparation is included?
- Is paint included, and which exact product?
- Are taxes, equipment and disposal included?
Labour is the main cost
HomeStars estimates that labour represents roughly 60–70% of a typical professional painting project. That is why an inexpensive coating does not automatically create an inexpensive project and why preparation can move a quote substantially.
Labour includes more than applying finish paint:
- Moving and protecting furniture
- Masking floors, fixtures and adjacent finishes
- Cleaning, repairing, sanding and caulking
- Spot priming or full priming where needed
- Cutting, rolling, spraying or brushing
- Drying time and return visits between stages
- Cleanup, reassembly and final inspection
What moves an interior estimate upward
Surface repairs
Nail pops, water damage, open joints, poor previous patches and cracked plaster require different levels of work. A quote for “painting the room” should explain whether repairs are included and to what standard.
Trim, doors and cabinetry
Detailed surfaces can take more time than broad walls. Cleaning, sanding, adhesion primer, careful application and curing all matter. Cabinetry should be quoted as a dedicated coating system rather than bundled casually into wall painting.
Occupied rooms
Furniture movement, daily cleanup, dust control and maintaining access add time. An empty home is usually more efficient than a fully occupied one, but the estimate should not assume the house will be empty unless that is agreed.
High or difficult access
Vaulted ceilings, stairwells, open foyers and obstacles may require specialized ladders, platforms or lifts. Equipment and setup time belong in the scope.
Dramatic colour changes
Deep colours, bright whites and major changes can require different primers, bases or additional coats. The exact product and coverage plan should be confirmed after colours are selected.
What moves an exterior estimate upward
- Peeling or chalking old coating
- Rotten or damaged wood requiring separate repair
- Two- or three-storey access
- Detailed trim, shutters, railings and multiple colours
- Masonry, stucco or mixed substrates
- Lead-paint precautions on older surfaces
- Limited weather windows and repeated mobilization
- Extensive masking around roofing, windows and landscaping
Paint quality affects cost in two directions
Premium paint costs more per container, but material is only one part of the project. A product that hides, levels and performs reliably may reduce labour or maintenance. A cheaper product can be appropriate for a straightforward space when its performance matches the use.
Compare exact product lines, not only brand names. Flat, eggshell and semi-gloss products within one brand can have different coverage, VOC information, recoat times and durability.
Room-by-room versus one coordinated project
Painting several rooms together can reduce repeated setup, travel and protection. It can also make colour transitions and sequencing easier to coordinate. Room-by-room work may fit cash flow or occupancy better, but the total cost can be higher than completing the same scope in one mobilization.
What should be written into the estimate
- Every room and surface included
- Preparation and repair allowances
- Primer and finish products
- Number of coats or the performance standard expected
- Colours and sheen, when selected
- Furniture and fixture responsibilities
- Access equipment
- Cleanup and disposal
- Schedule and working hours
- Exclusions and conditions that could change the scope
- Whether HST is included or added
How to compare three painting quotes
Do not rank estimates by total alone. Normalize the scope first. One quote may include ceilings, trim, repairs and premium paint while another includes only wall coats over the existing condition.
| Compare | Why it matters |
|---|---|
| Preparation | Determines adhesion and finish quality |
| Included surfaces | Prevents a low total built on missing work |
| Exact products | Shows whether the systems are equivalent |
| Coat assumptions | Clarifies coverage and colour-change risk |
| Insurance and business documentation | Separates professional scope from informal labour |
| Change process | Explains how hidden damage or added work is approved |
A better first message produces a better first range
When requesting an estimate, include the address or community, approximate home size, rooms and surfaces, ceiling height, current and desired colours, known damage, occupancy, timing and photographs. For exteriors, include every elevation and close-ups of failure.
Send Gillet Painting a clear project description and photographs. Stephan can then determine whether a preliminary range is responsible or whether the surfaces need an on-site assessment first.
