The cost to paint an average size room (10X12) ranges from $380-$790, not including ceilings, trim or cost of the paint. DIY, this can cost between $200-$300. When estimating the cost, painters will start with how much paint will be required to complete the job. To know this, they first need to know the size of the area to be covered. The easiest way to calculate the size of the paintable area is to add together the length of the wall and multiply it by the width of the room from floor to ceiling. The resulting amount is the room's square footage. This total is a starting point, as it is not all paintable surface. The painters won't paint the windows and doors, for example, and they must account for ceiling trim and baseboards as well. The next step is to subtract the area of the doors and windows -- along with the square footage of the trim and baseboards -- to get an average. Then, use the same calculation (length x width) on the windows, doors, trim and baseboards, and subtract all of those numbers. The result of this equation is the square footage of the room's walls. This is your surface area number. (Painters will typically add a little square footage back in to this amount to account for extra paint, which may be required.)
To win work, contractors generally have to bid against other suppliers. To make an accurate bid, they estimate the time and materials required to complete the job. They measure the area to be painted and discuss the type of finish the customer requires. They assess the quality of the surfaces to work out how much remedial work they must carry out before painting. They might have to remove old paint or wall coverings, or repair cracks and other damage. They also calculate the cost of any essential equipment, such as scaffolding for exterior walls.
It is often necessary to have a rental property painted -- whether it's to make it your own before you move in or to clean it up for someone new when you move out. Some buildings and landlords have pre-selected painters, while others will contract companies to paint on an as-needed basis. If your landlord or building doesn't have a pre-selected painter, see if you may be allowed to paint the walls yourself. If you're moving in and selecting a non-neutral color, understand that your landlord may require you to repaint the walls the original color when you move out -- and ensure that you're ready to make that investment down the road.
This article with comments was terrific - it was so informative. I found the advice useful. It addressed specifics like the condition of the dry wall surfaces, any additional repairs such. pin holes, chalking, smoothing of wall surfaces, absorption of paint and number of coats that may be needed. It should also include insurance coverage, and reflect the clean-up afterwards. Having a written contract with the company's letterhead is a must.
The only time it's acceptable to mix water in the paint is when you're using a deep or ultra deep base paint to reduce its stickiness, which is rare with new paint technology. Dark primary colors are composed almost entirely of tint that makes it very hard to work with without adding water. (You never use a sprayer and need to thin paint.?) If i was still in the industry I'd take the time to make a better article than this. Take this for a grain of slat. Use a reputable painter or someone you know you can trust or has been referred to you by someone you trust. I wouldn't hire anyone I had to watch like a hawk to make sure they're not screwing me.
Interesting information! We just got scammed in White Stone, Virginia... we chose the same color, but went from a flat to an eggshell finish. I wasn't available to stand over the painter while he painted. For such a detailed job, I marveled at how quickly he finished the project! After he was paid for the job, we discovered all he did was roll paint across the walls and close to the crown, baseboards and detailed trim around windows and doors leaving about an inch or so of the flat finish. By using the same color, he didn't even do the job he was paid to do, which explained why he could finish the job so quickly. By using the same color... he got lucky and passed it off as a completed job not bothering to paint to and cut in around the trim. Upon further evaluation of our walls we could see exactly where he stopped because we could see the difference between the flat and eggshell finishes. There are walls he didn't even bother to paint. Then where he did paint near the crown when we were in the room watching ... he hit the crown moulding and tried to tell us it was already there... and tried to sell us on painting the crown moulding. I am so disgusted and upset!! He'll be hearing from us to rectify the situation.
IF the average cost is $1700 to paint an interior, then that means the cost of paint is approx. $200 (12% of the job). Or better said 5 gallons of paint (if the average cost is $40 retail). The average room takes 1.5 gallons which will cover 3 average rooms. Doesn't sound to average to anyone with knowledge of this industry or a average house. You are misleading consumers and should do a better job in your research. No wonder so pay people think prices to get work done by professionals is high. Its not high, its actually average which is more like $3700.
