SoftWashing utilizes solutions to break down and clean the surfaces along with a high volume/low pressure rinse. This insures that the algae and mold growth is killed in areas you can’t see and prevents damage due to high pressure.
Pressure Washing utilizes high pressure to blast off the algae and mold. This will remove some, but not all, of the growth and it will return much quicker than using the Softwashing methods. Pressure Washing can damage the surface because of the high pressure. It can also send water up and under the siding causing water damage to the insulation.
