Some of the most common routine maintenance required to make your home sparkle is the removal of remove algae, mold and mildew.  You will generally see these growing on the north side of your home (in the northern hemisphere) or heavily shaded areas where the surfaces do not receive much direct sunlight.  If cleaned frequently removing these ugly, annoying contaminants is relatively simple.  We have read that using bleach or other commercially available products retards future growth, but from our perspective school isn’t out on this one.  Normally power washing alone is adequate to do a reasonable job of cleaning your sidewalks, roofs, or siding.  When used in conjunction with a good detergent and a scrub brush it does an even better job.

Health and safety issues should be a top concern.  Beyond potentials allergenic reactions some people suffer from exposure to these organisms, a number of other considerations should be made.  Proper eye protection and safety gear (gloves, boots, etc.) are certainly advisable.  Extreme care should be taken when working from ladders or on roofs, especially considering one is using a high pressure cleaning device that can easily upset one’s balance, potentially with catastrophic consequences.

As is the case with any power washing options there are a number of other considerations that must be addressed in order to achieve professional results.  The distance and angle the nozzle is held in relation to the surface plays an important role in the “evenness” and lack of streaking of the finished appearance.  Depending on what one is cleaning the pressure used to actually clean the surface (not the pressure the machine develops!) is an important factor.  Too much pressure and softer materials (i.e. roof shingles or wooden siding and trim) can be damaged.  Too little and they are not cleaned effectively.
