Every spring, as things start to warm up outside, homeowners across the country realize it’s time to spruce up the exteriors of their homes. One of the many things that people realize they need to get done, is to remove the unsightly green and black stains from the side of their house. These stains many people may not realize, are generally caused by biological growth such as mold and algae. People may decide to get out their power washer if they have one, or contact a local power washing company to have it cleaned.
The typical method for the cleaning, is to use high pressure water in the 2000-4000 psi range to blast off the accumulated growth. Many people are unaware however, that this may damage your home. High pressure water can force its way under the siding and potentially cause water damage, or cause more biological growth.
The alternative and superior method, termed “soft washing” is a way to remove mold and algae without the risk of blasting it with high pressure. The average home owner has often never heard of this method. The method works like this: A cleaning solution is applied to the siding and allowed to “dwell” or sit on the surface to kill and remove the accumulated growth. After the solution has dwelled and killed the growth, it is then rinsed of the side of the home with a low pressure spray. Depending on how dirty or neglected the siding is, this process may need to be repeated several times until the desired result is achieved.
In addition to protecting your home, you could also consider the added benefit of safety. Often times, when doing a typical “pressure washing” of a house, ladders are generally needed to get to hard to reach areas and some work may even need to be done from the roof. This can be potentially dangerous. With soft washing however, with the right equipment, most if not all of the work can be performed from the ground even with houses in excess of 3 stories tall.
Once all is said and done, the siding shines like new with all the dirt and growth removed. Some people, that power wash their homes themselves with high pressure complain that they have to do it very frequently, sometimes every year or even twice a year. Given that the algae and mold were killed at the source, the home will generally stay cleaner for longer and may not need to be cleaned again for several years saving you future time and money.
