QUESTION: Why do we see so much power washing done on home exteriors for paint removal?
ANSWER: It’s cheap and fast!
Many contractors use power washers to pressure wash away dry paint peeling off wood siding. Contractors charge $500-$1000 for a one or two-story house. DIYers can buy a pressure washer for $100-$400 or rent one for $65/day. Once you get the hang of the technique, the job can take less than 3 hours for 2,000 sq. ft. Power washing is, indeed, the cheapest and fastest surface preparation for repainting siding – no matter who does the work.
Why not power wash your wood siding in preparation for repainting?
The pressure pushes water into the wood. Sometimes, even a second rinsing is needed. Moisture in wood is the most common reason for paint failure. The wood after pressure washing must thoroughly dry for several days to assure new paint will stick long-term. Both professional painters and DIYers, often do not wait the full, necessary drying time before repainting. When this happens, the new paint as well as the old paint will pop off from the moisture trapped underneath.

Paint chips in water are difficult to contain and to clean up and often, are dangerous. Although the water is absorbed by the soil underneath the wall, the paint chips are not. These chips can attach to the shoes of playing children or the paws of pets. Most old paint on pre-1978 homes is lead-based. Lead paint chips are very toxic for children if ingested or inhaled. See this blog for more details: . Pets easily can get poisoned, too, from these paint chips getting on their paws and then into their mouths. In addition, power washing uses chemicals such as bleach as cleaning agents to remove and kill mildew, fungus, and algae. These chemicals can damage shrubbery, grass and gardens.

The wood siding is easy to mar. The pressure of the stream of water can gouge and leave the wood surface uneven. Only the loose, peeling paint will release from the wood. The rest of the paint will stay on the wood. When the wood is repainted, the newly-painted surface will look irregular and unattractive.
