Maintenance. What do I mean? Let’s take that suit/dress illustration again. Imagine you are wearing your favorite suit or dress and then you get an amazing red wine sauce on it. Oh no! What is the first thing you try to do? Grab a napkin and some water and dab it out. Why? Because you and I know that if it “sets in” then the stain becomes that much harder to remove. That same principle applies to your home, especially if it has stone, brick, stucco, or other similar materials. Leaving any staining for too long can make it that much more difficult to restore to it’s original condition. Also, if you happen to have cedar shingle siding or other type of wood siding, algae and mildew growth can literally and permanently damage the wood if left untreated.
So there are two reasons to get your home cleaned with power washing or pressure washing (please, please, please refer to my comments on soft washing. I know the terminology can be confusing, but a power washer in the hands of the wrong person can do tremendous damage to your home).
