House Painting: How Much Should House Painting Cost?

Depending upon your situation the average exterior paint job nationally costs about $2,479. Painting interior rooms inside your home with an average room size of 10×12 can range from $369-$779.

This does not include ceilings, trimmings or crown molding. Cost of needed materials for interior painting projects include masking tape and paper, surface repair and preparation material, primers, and cleanup supplies.

Whether you’re looking to spruce up a single room or breathe new life into your entire house, painting your home is one of the best ways to get it done. However, before you pick up a brush and a random gallon of paint, there are quite a few things you need to know in order to avoid mistakes and be sure that you’re happy with the results.

Repair and repainting can be necessary when you begin to notice cracks and peeling. Home owners who ignore these signs may end up paying for it down the road with a more expensive paint job.

Six Things You Should Know Before You Paint Your House

The finish is just as important as the color

One of the most common mistakes that people make when purchasing paint for the interior of their home is not understanding the difference and importance between the different finishes available.

Not all finishes are ideal for all areas of the home. For example, high-gloss and satin finish paints are better for high traffic areas because they hold up well to being touched or cleaned frequently.

Extension poles will save you a lot of ladder climbing

One of the most tedious parts of painting either the interior rooms or exterior of a house is having to constantly climb up and down a step ladder to reach the higher areas.

It also adds an unnecessary element of danger to the project. You can avoid this though by simply purchasing an extension pole for your paint roller so you can get to those hard to reach areas comfortably from the ground.

Combine all of your paint to ensure color uniformity

One final mistake that many people make when painting, especially when it involves a larger project, is to open each gallon of paint one at a time as they work. While this may seem like a logical way to proceed, it can actually result in uneven patches of color that you won’t be able to see until after the paint is dry.

Patches can also be very tedious and time consuming to correct. Instead, empty all of your gallons of a certain color into a resealable plastic paint bucket.

Try a sample before you buy

Another common mistake that people make is to bring home a swatch book and hold it up to the wall thinking that that will give them a realistic impression of how a color will look. The truth is that more often than not, homeowners are shocked when they get a full gallon of paint on the wall that the color doesn’t look the way they had imagined it.

Keep in mind that many colors will change a great deal throughout the day as the light changes. In order to a avoid costly disappointment, purchase a sample size of a few colors you are interested in and paint them on two adjacent walls of the room you are planning to paint. Leave it there for a few days to observe how it changes in the light and decide whether you truly like it.

Do the math ahead of time

Another benefit to applying a sample of your color options is that it will help you to know ahead of time how many coats of paint you will be needing in order to achieve the desired color. Once you know how many coats you will need, you will better be able to estimate how much paint your job will require.

In order to calculate how much paint you’re going to need, add up all of the square footage of the area you will be painting and don’t forget to include the dormers and alcoves. It is also a good idea to include a little extra for wiggle room. Again, remember to account for multiple coats if necessary.

Invest in prepping your space properly

It’s true that prepping for a painting project is about as entertaining as watching paint dry. However, in the long run you will be infinitely more grateful to yourself if you suck it up and take the time to prep properly.

This means making sure that the space has been cleared of furniture (or furniture has been properly covered with drop cloths), the walls have been properly cleaned, missing drywall has been patched, etc. It’s also important to take the extra time to apply a coat of paint primer which will make a big impact in the end result of your paint job, especially for bolder colors and covering up bold colors.

Pouring spout

Attach the spout to a gallon of paint and pour without any mess.

Five-gallon bucket

For big jobs that require multiple gallons of paint, keep the color consistent by mixing all the cans in a large bucket.


Place this inside the bucket to wipe any excess paint off the roller.

Roller tray

Use a metal or sturdy plastic tray for smaller projects.

Tray liner

Save clean-up time by using a disposable paint-tray liner.

Roller cover.

A 3/8-inch nap provides the best finish for most interior walls.

Angled sash paintbrush

To paint trim, use a two-inch angled brush, which will give you more control.

Blue painter’s tape

Essential for protecting trim or walls that you don’t want to get paint on.

Drop cloths

Protect furniture with plastic coverings. Place a reusable canvas drop cloth, which is less slippery than plastic, on the floor.

Hole filler

Quicker than spackling: Dab hole filler into small holes in the wall.
