So, just how expensive is expensive? The average cost to paint the exterior OR interior of your home is about $2,000. I don't know if that sounds like a lot, but the national average to paint a home's interior is $2,000 and a home's exterior is $3,000. The lower cost of hiring a Dallas home painter for your home's exterior has mostly to do with the favorable weather. Of course, this is still just an average for special considerations and house sizes you may be looking at as much $5,000-$7,000 or as little as $900. You can also get individual rooms or other small painting projects done for as little as $300-$500. Home Painters Broomfield CO
