Three Common Pressure Washing Problems to Watch For:
1. SHOTGUN & ARTILLERY FUNGUS
Shotgun fungus, those "tiny black specks" that appear on your siding, are about impossible to remove. Often mistaken for insect feces, they are actually the mature spore masses expelled from the fruiting bodies of fungus known as Sphaerobolus Stellatus".
This fungus gets its name by firing spore masses in the air as little as two feet to a maximum distance of thirty feet, speckling siding, down spouts and windows. The longer these spores have been in place, the harder they are to remove.
In most cases, we can generally remove half of the shotgun fungus. The water pressure will usually "skin" the outer surfaces of the spore. This leaves the spore exposed to the sun, which will then "bleach" them off of the siding. There is no product that kills shotgun fungus, but you can keep it at bay. Consider switching to inorganic mulch, such as stone or pea gravel. Prior to the application of inorganic mulch, we recommend the complete removal of the existing mulch in order to lessen the chance of reoccurrence.
When metal is exposed to rain or humidity, it slowly deteriorates and causes oxidation. A prime example of this type of oxidation occurs on your gutters as the aluminum is exposed to the elements of the weather, such as rain, snow etc. The metal starts to stain a grayish film, which during the hotter months of the year bakes onto the gutters.
Power washing works wonders on vinyl siding, but does little to remove the oxidation that can be found on most trim and gutters around the home. Nothing short of a long and grueling hand scrubbing will take care of a tough case of oxidation.
Refer to our Gutter Polishing service on the home page. You can attempt to wash gutters down all day, and never succeed at removing any of the oxidation. This is one of the most difficult stains to successfully remove. We have the chemical formulation for successful removal 95% of the time.
Occasionally, when power washing your home a small amount of water will get behind the siding. Hours after we have left, the water will start to make its way onto the exterior surface of your siding. As it drips out, it will usually pull some dirt out with it, resulting in a mark down the side of the home.
This problem can be remedied by simply giving the runoff area a quick spray with the garden hose to rinse away the mark.
