For bigger houses or for faster work on smaller ones, rent a high-pressure spray cleaner. This device attaches to your home's water-supply system and puts out a jet of water at a pressure of about 600 pounds per square inch. It is equipped with a handheld wand tipped with a trigger-activated nozzle. The pressure is high enough to dislodge not only stubborn dirt, mildew, stains, and dried-on sea-spray salt, it's enough to remove peeling paint. In fact, if the jet nozzle is held too close to the surface it can even peel off perfectly sound paint, split open shingles, and drill a hole in siding. So follow the manufacturer's directions and wear goggles and protective clothing.
Even if you think you'll probably do the job yourself, it's good preparation to seek estimates from professional home painters, whether your painting the exterior or interior of your home. Then you'll have a financial point of comparison and you may benefit from what a home painting contractor has to say about the condition of your home, color choices and types of paint available. Let the painter make his pitch for a professional job before you decide what to do. You can still opt to do it yourself while having learned something worthwhile.
The cost to paint the exterior of your home will vary depending on the size of your home, the condition of your siding, type of paint used and other factors. The average cost for labor and supplies ranges between $1,800-$3,800 and it may cost $6,500 or more for a large, custom project. In addition, you may need to pay more if there is damage to your siding or other challenging aspects of your job.
