Dirt is abrasive – like sandpaper.  When considering decking or other organic surfaces dirt is ground in every time you step stripping away the sealant.  Oils, stains and dirt on driveways, pavers and walls are harder to remove over time as they seep further into the concrete, bricks and timber.  Lastly the roof on the property builds up with dirt, leaves, pollens, lichen, moss and other forms of bacteria that may present a health hazard to the occupants of the building. Pressure washing can help to remove dirt & stain on hard surface.

If you have allergies, asthma, emphysema or other breathing problems, one major source of the problem could be the pollens, fungus and chemicals brought into the house or office.  Pressure cleaning outdoor walkways, paths, pavers, courtyards and any other external surface will reduce the risk of unwelcome trigger compounds being entered into the building. Pressure washing the roof as mentioned earlier will also significantly reduce the risk of pollens, fungus and bacteria entering the building.
