Pressure washing, or power washing, is the use of high-pressure water spray to clean surfaces and objects such as buildings, vehicles and parking lots. Pressure washing is used to remove paint, grime, dirt, chewing gun, mold, mud – whatever you need – from a surface you need cleaned. Depending on the surface being cleaned, higher or lower pressure should be used, as well as the appropriate nozzle; when it comes to pressure washing large areas or high on a wall, we always recommend using a professional service like ours. While pressure washing may seem no different than washing with a hose, there are safety concerns. The high pressure of the water not only poses a direct contact harm, but it can also send dislodged materials at a high speed.
