# How Much Does It Cost To Paint a House in Canada?

Statistics from 2017 show the average to paint the exterior of a house in Canada is around $2,500, while an interior average is $2.50 per square foot. Of course, size matters. Without a basic idea of all the factors that determine the final cost, there isn’t a simple way for a homeowner to know if the painting costs per square foot Canada companies charge is fair, which is frustrating.

So how do you know if a painting estimate is reasonable? **To do that you need to take into consideration the type of paint, the application products, whether it’s interior or exterior, and the need for any special painting equipment.**

These factors come into play when determining the cost of painting a house in Canada, so read on to learn more about what is included in that estimate to determine if the price per square foot is reasonable.

**Interior vs. Exterior Painting Cost Factors**

Painting costs differ per square foot depending on environmental conditions. Interior spaces are weather and temperature controlled, and exterior surfaces demand a perfect seal from the elements.

## Cost of Painting Interior of Your House in Canada?

The average cost to paint a ten by twelve-foot room ranges from $350-$800. This cost varies due to the paint formula selected and whether or not wall repairs, ceiling paint, or trim painting is needed. Trim painting alone can cost $200-$300 on average per room.

Will you need a primer to cover the current paint color? If so, this is an added cost. Figure the average of 200 square feet of coverage per gallon of primer at an average price of $25. You can skip primer if the old color is relatively close to the new paint shade and no major wall repairs were done.

Choosing the correct paint for your project is critical to achieving lasting, quality results. When you hire a professional, you will waste money and end up with peeling, scuffed, or faded paint if you do not pay more for quality paint.

### Interior Paint Costs

An average for a good quality interior paint is $45 per gallon. The price difference between a flat finish and a high-gloss finish can be around $20 per gallon within the same brand of a paint company.

Interior paint and primer is typically water-based and is made to resist stains and allow you to clean off dirt.

A professional painter knows that good paint is worth every cent. Quality paint goes on smooth and provides a vibrant solid color that is durable, which makes their customers happy.

### Interior Painting Costs Per Square Foot in Canada

To calculate interior paint cost, determine the square footage of the space you need to paint then divide that number by 350, which is the average square-foot coverage of a gallon of paint.

The final number will be the gallons you need times the cost per gallon of the formula you choose. This number is only for the price of the paint alone, without labor or other materials.

For example, a 12×15 foot room with eight-foot-high ceilings is 1,440 square feet of wall space. That number divided by 350 is 4.11. Since you would need to buy five gallons of paint at say $35 a gallon, your cost would be $175.

## How Much Does it Cost to Paint a House Exterior in Canada?

At an average of $2500 for an exterior paint job, again many factors determine the final cost, like actual size, or if a contractor needs a sprayer, scaffolding, or has to hand-paint decorative trims in different colors.

Exterior paint and primer are made to withstand the elements, protect against fading and deter mildew growth.

### Exterior Paint Costs

The average cost for a gallon of exterior paint is $48. Exterior paint needs a high number of resins to aid in weather protection and wear. Costs will vary when painting over different substrates such as:

- Stucco
- Cement board
- Wood
- Vinyl
- Metal
- Concrete block

Expect to pay from $400 to $900 per 250 square foot of exterior surface depending on the substrate and prep work involved. Also, add in an average of $35 per gallon if an exterior primer coat is needed. So the average cost to paint the exterior of a 2,000 square-foot home would be between $3,200-$7,200.

Did your neighbor paint their wood-sided house for a certain amount, and you assume your vinyl-sided house quote will be the same? These surfaces require different prep-work before painting so your estimate may be higher or lower.

The additional work of painting trim or changing the color of paint for soffits and eaves will increase the estimate.

**Other Costs That Determine The Final Estimate**

**Supplies**

The additional cost of the extraneous gear needed for paint prep like drop cloths, rags, wall putty/filler, caulk, and tape add up quickly and will add to the final estimate to the tune of $200-$300.

Professional companies provide all of the essential extras to prep and finish your painting project. They also tend to use more expensive products because they do a better job, like a painters’ tape that does not allow paint to bleed under the edge.

Using quality products eliminates extra work for your painter, but also provides you with excellent final results and the additional cost on your estimate for this expense is justified.

**Final Questions**

*Why** sh**ould** you hire a professional painting service?*

It’s worth paying a professional for such a large task since they already own all the equipment needed for your job aside from the paint. If you decide to do it yourself, you will have to buy and store a large number of painting supplies that you may not need again for years.

Stairways, bathrooms (especially around the commode), and high exterior eaves create extra work that many times demand lots of flexibility and special ladders, scaffolding, and safety equipment. Professionals spot these issues during a consultation, but a homeowner may not find them out until it is too late and they are stuck with an unpainted area.

Do expect a higher per-square-foot charge for a well-regarded painting contractor. Don’t assume an estimate is more than average for no reason. If you do not see a breakdown of costs within your estimate, ask questions of your painter to get clarification of why a charge is a certain amount.

A good company knows their reputation relies on quality results, so they use top-of-the-line products and the safest equipment and practices that make their job easier and results in a superior finish for their customer.

*Should you insist on inexpensive paint and supplies to save money?*

As much as you would like to save money, inexpensive paint and supplies result in a poor paint job with a short lifespan. When it comes time to wash the surface, interior paint may scrub right off. Exterior paint may peel or fade quickly.

Low-priced paint and supplies do cost less. But, your contractor will have to buy more gallons of that inexpensive paint to adequately cover your walls, which then negates any price savings.

Cheap brushes and rollers leave you with splotchy, fuzzy walls and unclean edges, so don’t insist your painting contractor skimp on supplies either.

Painting is one job you never want to “go cheap” on. Spend more now on quality products so your completed project will look fantastic and be durable. By not having to repaint your home for many, many years, the overall cost is less.

*Should you hire the painter with the lowest estimate?*

*Should you hire the painter with the lowest estimate?*

A low estimate doesn’t mean you’re getting a bargain. One reason you could attribute the low cost-per-square-foot is the use of poor-quality paint and supplies by the painter.

They may be inexperienced and wish to gain more customers by underbidding the competition, but be aware that the inexperience of a painter means a job will take longer to finish and the results may not be as clean.

A low estimate can also be because a painter is not licensed and insured and does not have to factor those costs into a bid.

By taking what you’ve learned here, you can figure out the cost of painting a house in Canada. Now you have the tools to understand what factors in your home could adjust the total from the average cost when you receive a professional estimate to paint your Canadian home.

How did you arrive at a total of 1440 sq.ft of WALL space for a 12 x 15 room with 8 foot ceiling?

12x15x8…

12×15 room w/ 8′ H. is = to 432 sq. ft. After that mistake, I didn’t bother reading the rest of your info.

Thanks Theo, but how did you arrive at 432? To measure the area we used 12x15x8 = total area of 1440

This is worrisome. The correct wall space is 432 sqft. You’ve calculated the volume of the room in cubic feet.

Two walls at 12’x8′ = 96sqft each

Two walls at 15’x8′ = 120sqft each

96 + 96 + 120 + 120 = 432 sqft

Assuming an estimate not taking into account windows and doors:

(12*2+15*2)*8 = 432

1440 is the volume of the room

you calculated 12ft x 15ft x 8ft, which would be 1440 cubic ft.

Really, what you have in a 12×15 room, is a 12ft wall, a 15ft wall, another 12ft wall, and another 15ft wall. Which is a total of 54ft of wall lenght, x 8ft height = 432 sq. ft.

um… your four walls are (12+12+15+15=54 feet x 8 = 432) square feet of total wall space. Do you get it? the 12 foot walls if they are 8 feet high are 96 square feet and the 15 foot walls, if they are 8 feet high, are 120 square feet. that’s 96+96+120+120=432!!!

@Neighbourhood Painters, there is a fundamental flaw in your math or there is some confusion. Here the point is to paint the room not to fill the room with paint. What you calculating is L x W x H and that gives volume. While (2xL + 2xW) x H gives the surface area to be painted. I suggest to do a refreshing math course. FYI the price is around $2 – $3 per square foot of carpet area. This is what we pay as a home builder.

You’re calculating the volume when you multiply all three together. You would want the surface area.

12X8X2=192+

15X8X2=240=432

Should you want to paint the roof as well it’d be another 12X15=180 on top of that.

Just to help out for the future, to calculate square footage of a room you multiply the width of the wall by its height. So for a 12 x 15 room with 8′ ceilings, you’d have:

12 x 8 = 96, x2 = 192

15 x 8 = 120, x2 = 240

So for all four walls, 192 + 240 = 432 square feet.

actually Theo is correct. calculation is (12+12+15+15) x 8 which is 432

Hello Neighbourhood Painters ☺

The sq. ft. wall area in a 12′ by 15′ room (with 8′ ceilings; no windows) calculates as : 432 sq.feet.

Here is the mathematical proof:

2 walls @ 12′ long x 8′ high = 2 x 96 sq. ft. = 192 sq. feet

2 walls @ 15′ long x 8′ high = 2 x 120 sq. ft. = 240 sq. feet

192 sq. ft. + 240 sq. ft. = 432 sq. ft. … of total wall space in a 12′ x 15′ room, with an

ceilng and without windows.

Cheers. ☺

Umm if you do 12x15x8, that measures the volume of the room, wouldn’t finding the surface area of the walls (ie. (2x(12×8))+(2x(15×8))), be more reflective of the amount of paint needed for the job, as that reflects the amount of paint needed to cover that area?

That calculation will give you the volume of the room in cubic feet. To determine surface area, you need to consider the height and width of each wall, then add them together.

For example:

North wall: 12′ x 8′ = 96 sq ft

South wall: 12′ x 8′ = 96 sq ft

East wall: 15′ x 8′ = 120 sq ft

West wall: 15′ x 8′ = 120 sq ft

Total wall area: 96 sq ft + 96 sq ft + 120 sq ft + 120 sq ft = 432 sq ft

Dude go get a math class with your Grade 1 kid. This will help you understand what is the difference in Volume and Area.

Hi there,

Theo is correct.

12x15x8 is 1440, but that’s the area of a cube.

To calculate wall space, it would be:

12(length) x 8 (height) = 96

15(length) x 8(height) = 120

That’s for 2 walls, so you have to double them.

96×2=192

120×2=240

Total wall space is 432 sqf.

Thanks

Well area is 432 sqft.

Wall 1=12×8=96sqft

Wall 2= 15×8=120sqft

A= (wall A 1)2+ (wall area 2)

= 192+240

=432 sqft

Your calculation is cuft or room volume not surface area.

Hope this helps.

(12×8)x2=96×2=192

(15×8)x2=140×2=280

280+192=472

You’re finding square footage of walls, not the volume of the room.. It’s not rocket science.

(15×8)x2=120×2=240

192+240=432

Whoops, long day. My bad haha

12x15x8 =1440 ft^3 which would give you the volume of the room in cubic feet… (ftxftxft = ft^3) you need to go 2x(12×8)+2x(15x8ft) = 432ft^2… actual square footage of the walls… if you add in painting the ceiling its 12×15= 180ft^2 for a MAX total of 612ft^2 square feet if the ceiling is being painted as well.

Your area calculations are totally wrong. If you multiply l*w*h you are calculating volume. Wall surface is (l*h*2)+(w*h*2). That is 432 for this room. Ceiling is l*w=180 sq/ft. 1440 is way wrong.

I’m going to have to agree with Theo on this.

1440 is the volume of the entire room in cubic feet

Perimeter of room x Height = wall surface area

2(12’+15′)x8’=432 sq ft

Neighbourhood Painters… you guys calculated volume (cubic square feet of the room), not wall surface area. To calculate the surface of the wall it would be length x height.

12×8=96

Therefore all the lengths of the walls added together, multiplied by the height is the correct formula.

(12+15+12+15)x8=432

Then multiply the total wall square footage by however many coats are needed, then divide by the paints coverage rate to determine amount of paint needed.

For two coats:

432×2=864

864/350=2.47

You are going to need 2.47 gallons approximately for the 12 by 15 room with 8 foot ceilings.

In a 12 x 15 foot room you figure out the square footage of the walls painted like this. You can do it the slow way and say 12 x 8 = 96 that is one of the 12 foot long walls and you have to add the other 12 foot wall which is 12 x 8 = 96 square feet and the 15 foot wall is 15 x 8 which is 120 and add the other 15 footer 120 and add them all together you get 96 + 96 +120 + 120 = 432. To do it easier you add up the length of the walls in this case is 12 +12+15+15=54

Then you multiply that by 8 equals 432 square feet. By multiplying 15 by 12 you got the floors square footage. To get the walls square footage you take the length of wall and multiply by the height and you get the square footage of walls surface. That means you can add all the lengths of the walls up and multiply by 8 if the walls are 8 feet tall. If you cannot understand it with the way I put it like this. If it is a normal shaped room so it is a 12 x 15 foot room that has 12 foot side and the opposite of that a 12 foot side and the other two walls are both 15 feet that would mean it is 54 feet x the room height of 8 feet and 432 square feet of wall area. Who taught you to multiply the 12 x 15 x 8. That makes no sense. You got the square footage of the floors space and then you multiply the floor space by 8 like you have to paint the area of the floor 8 times to cover the walls. If you want the floor and ceiling included take the 12 x 15 which is 180 and multiply by 2 and you get 360 square feet for floor and ceiling and 432 for wall surface which equals 792 square feet. The prices you guys quote if you use that way of figuring out painting surface must be huuugee

I would be one rich painter if that was how you calculated a room.

Wall space is 432.

2 walls are 12 so 24×8=192

Other 2 are 15 so 15×8=240

So you got 432sqf.

Thats how u do it.

Sorry 30×8=240

Neighbourhood Painters – That formula you are using gives you volume not wall space. 1440 ft^3. Unless you are planning on filling the room with paint you need to iron out your calculations.

That’s not correct math. You are calculating VOLUME of the air inside the room with that math. NOT wall area.

Correct math per wall = ((12+15)*2)*8 = 432sq.ft not counting doors/window areas (door usually approx 20 sq ft and windows approx 15sq ft) – you would subtract those values.

Basically takes the total width/length of ALL the walls and THEN multiply by 8ft height. |

Quick Maths.

I believe Theo calculated as follows: for this rectangular room 2 walls are 12 feet wide by 8 feet tall and 2 walls are 15 feet wide by 8 feet tall. 12×8 = 96 x 2 walls = 192 square feet;

15×8=120 x 2 walls = 240 square feet. 192 + 240=432 square feet in total. (he is not including the ceiling). The calculation of 12 x 15 x 8 gives the volume of the room.
