Generally speaking, a gallon of paint will cover about 350 square feet. If this is the first time drywall is painted, it will soak up more paint. And remember to factor in whether your job will require one or two coats of paint. Dark and bright colors will require more coats of paint, as will painting a lighter color over an existing darker color. Divide the paintable wall surface by 350 to determine how many gallons of paint you will need to buy. If there’s an odd number with less than .5 leftover, round down, if it’s over .5 round up.
It’s a lot of tedious and time-consuming work, and it’s usually wise to hire an experienced painter to tackle the job for you, especially for bigger jobs or jobs that require a ladder. A painting pro can provide an estimate by the square foot of your house’s interior or exterior, the level of difficulty posed by the house’s configuration, and the going rate for labor in your area. Start by researching the pros and cons of various types of paint. Then, if you’re using pro, get three estimates to make sure you’re getting the best deal. Painting a house is not inexpensive, but the right work pays off in protecting your home and keeping it looking fabulous for years to come.

File the necessary business documents. For starters, you’ll need a general business license to begin taking on contract work. You may also have to have other specific licenses that permit you to operate in off-limits zones or handle certain materials. A separate home business permit will be required if you plan on using your own residence as the headquarters for your contracting business.


Paint made for the exterior of a house is formulated differently from that destined for interior paint jobs. Exterior house paint is blended to withstand rain, wind, and varying temperatures, while interior house paint is formulated to hide minor imperfections such as brush marks, handprints, and scuffs. Interior paints can be made washable for convenience, and doesn’t require exposure to light to cure.

We needed our stoop top replaced and the entire stoop waterproofed. The job went very well - work began on-time and ended a bit earlier than estimated. Mr. Ismail kindly explained every step of work to be done in advance and made sure that we understood and approved each one. When a layer of very old brick under the stoop was discovered and shown to be unsuitable for a modern cement covering, the workers quickly built a new layer that is much sturdier. The workers also replaced a crumbling stone border at the edge of our garden, sealed the stoop against moisture, painted the interior storerom room underneath the stoop, and removed dirt and debris. I highly recommend Rahat Construction!
