The average cost to paint a house exterior is $2,500 for a 2,400 sq. ft. two-story home, with most homeowners paying between $1,800 and $3,200. The final cost comes out to around $0.60 to $1.60 per square foot. With so many variables in pricing, you need to take them all into account before coming to your own estimate on how much your painting project will end up costing.


If you are unsure about what colors will work best in a space, you may wish to hire an interior decorator to help. Decorators can look at your furnishings, the size and shape of a room, and the amount of light it gets to help you determine the best shades for the space. Design services cost around $50 to $200 an hour, and can help you find the perfect colors for your home. Thornton Home Painting
When the primer is dry, caulk all small joints (less than ¼-inch-wide) in the siding and trim. Most pros use siliconized acrylics—paint won't stick to straight silicones—but Guertin and O'Neil like the new, more expensive urethane acrylics for their greater flexibility and longevity. O'Neil stresses that it's shortsighted to skimp on caulk. "If the joint fails, you're back to square one." Guertin uses the lifetime rating as his quality guide. "I don't expect 35-year caulk will last 35 years, but it should last longer than a 15-year caulk."
High-gloss paint is the most durable and easiest to clean of all paint sheens. It's ultra-shiny, light-reflective, and hard (think appliance-paint tough). High-glass paint has too much shine for interior walls; you'd find the reflections and drywall flaws distracting. It is a good choice for areas that sticky fingers touch, though, such as cabinets, trim, and doors. House Painting Thornton
Exterior paint averages $25-$40 a gallon, and a 3,000-square-foot home takes 15 or more gallons of paint, or $375-$600 just for the paint. However, really premium paint can cost $50-$100 a gallon, or $750-$1,500 for that large home. Doing it yourself also requires renting a pressure washer or sprayer for $50-$100 a day; extra-long ladders or scaffolding at $20-$75 daily; and a power sprayer for $50-$100 daily, plus masking tape, drop cloths and other supplies. However, it's possible to paint a large, two-story house for materials-only costs of $400-$600.
Once you have the interior square footage calculated, experts say you’ll want to divide by 350. 350 square feet is the average coverage of a gallon of paint (though some say 250-400 square feet). The average coverage for a gallon of primer is 200 square feet. Your square footage divided by 350 square feet gets you the number of gallons of paint you’ll need. Square footage divided by 200 gets you the number of gallons of primer you’ll need. You can save money by ensuring you don’t buy too much paint.
Depending on whether you're having your interior or exterior painted, the way a contractor applies the paint can make a big difference. For instance, primer is best applied with a brush while certain types of texture are best applied with a spray gun. Make sure the painter is skilled in using spray if you choose that method, as over-spray could become an issue and drive up the overall cost by using more paint. Thornton Home Painting

There have been instances of unscrupulous individuals pouring inexpensive paint into expensive paint buckets and overcharging customers. Make sure you have your painting contractor write exactly what type of paint products will be used to complete the job. Also, if you specify a brand, include that and the exact shade. It may seem silly, but making sure all of this is in writing will save you from misunderstandings and unnecessary obstacles to finishing your renovation.
A moisture meter will let your contractor know if there’s moisture in the stucco before starting. The wetter the material, the less ready it is to be sanded, painted, finished or covered. Your contractor will use a premixed stucco repair patch material to fill any small holes and will paint on dry days to avoid sealing in water. Painting rough stucco requires more paint. Brush painting stucco costs $112 per 100 sq. ft., roll painting costs $55 per 100 sq. ft., and spray painting stucco costs $25 per 100 sq. ft. Thornton House Painting
The real bulk of the work in exterior paint prep is surface prep. And make sure to avoid these missteps. The most difficult part of that prep is sanding and scraping. If you're working on an unpainted surface, you can give it a quick prep and move on. But most previously painted surfaces will need to have loose and flaking paint scraped off and the edges sanded flush. This is a tedious and tiring process, but it's an incredibly important part of the process. Painting over flaking paint will only result in new paint that flakes off, and skipping the sanding process will leave large, unsightly "divot" areas on your home. Power sanders can help speed the work, but be sure to use proper respiration and dust control. See this article on painting preparation for more tips on the critical steps of sanding and scraping.
