Mold and mildew are caused by moisture accumulation and can grow on virtually any surface. It's impossible to control the moisture outdoors, especially in the North Carolina damp winters. In addition to health risks, mold can also discolor surfaces if it is not cleaned off frequently. After a long winter, Spring is the time to start contacting pressure washing services to eliminate the mildew your home and property.
Pressure washing knocks off the grime and mildew by using a high pressure water spray onto the surface of the building, pier, driveway, sidewalk or patio. Depending on the degree of cleaning required, homeowners may find that soaking the area with an algae or mildew remover might be helpful in removing all residue on the first pressure wash.
Professional grade pressure washers are far more powerful than those available to the average home owner. Because of the increased pressure, professionals seldom need to pre-soak areas to be cleaned. Although more powerful than off-the-shelf pressure washers, professional grade washers are not likely to do damage to surfaces due to the skill of the user and the various nozzle attachements that most commercial services have available.
For better prevention of mold and mildew, homeowners can investigate the use of penetrating stains for concrete or wooden patios or piers which can extend the time between pressure washings.
