Dirt is everywhere, and for home owners it’s a nuisance. For cleaners, it’s a dream. Power washing is the chosen method for cleaning dirt, grime, pollution, and oil off of hard surfaces like concrete. There are several benefits to hiring a power washing service.
This is one of the easiest benefits to notice - curb appeal! Blasting away the dirt build up is an easy way to make your home look better. Rain easily distributes mud onto walkways and patios, and over time the mud dries and just cakes onto the concrete. Surface cleaners and pressure wands make short work of dirt build up.
Grease and grime from shoes also builds up over time. You notice this especially on well-worn walking paths and entry ways. The black discoloration can be cleaned up to make your entry way look new.
Mold is another element that can build up in concrete. Mold grows into the pores of the concrete, and the longer it is left untreated or uncleaned, the harder it is to eradicate. Mold also retains moisture and becomes slick when wet. This makes it a slipping hazard during and after rainfall. Be careful when walking on concrete overgrown with mold.
Soft Washing and Sealing
While power washing is an option to remove mold, we recommend having the concrete treated with a soft washing method. Soft washing uses low pressure and a cleaning solution as opposed to high pressure water. The soft washing solution contains a small percentage of sodium hypochlorite, or essentially chlorine, that kills the mold and releases its bond on the concrete. Light pressure is then used to rinse the mold away. This method is ideal because it kills the mold and helps prevent regrowth. Since mold is spore-based, simply blasting off sends spores into the air, which resettle on the concrete and begin growing again. Soft washing is more reliable at stopping the mold from returning.
A surefire way to prevent mold regrowth is to have the concrete sealed. Concrete sealer fills in the pores of the concrete and helps prevent moisture from seeping through. Not only does sealing prevent mold growth, it protects the concrete and prevents cracks due to moisture. When water gets into the concrete and freezes, it expands, then contracts when the weather is warmer. This fluctuation causes micro fractures in the surface that often become larger cracks.
