Many homeowners only consider exterior house washing when they’re selling their home, and of course a freshly washed exterior can certainly appeal to a buyer. And if the outside of your home looks good, it can add value to your home too. However, there are other reasons why once a year washing of your home’s exterior is a good idea. Dirt, mildew and mold collecting on the outside of your home can actually affect your family’s health, and regular exterior washing can get rid of all that. Moss and algae on the outside walls can actually damage your home too, if left untreated for years. Washing also removes all the spiders and cobwebs that inevitably accumulate on the outside of any home, despite them not always being easy to see. Exterior washing is easy and affordable, and it’s something that should be on your maintenance calendar.
