Many homeowners only carry out exterior house washing when putting their home on the market, and it’s true that a clean looking home has much more curb appeal. However, washing the outside of your home has other benefits too, and most experts will tell you that you should have it professionally washed at least once a year. Dirt and stains on the outside of your home can actually cause permanent damage, often removing the paint, and regular exterior washing can help prevent this damage. Your home is also a lot healthier when you clean the outside of it, as cleaning gets rid of potentially harmful dust, mildew and mold. Washing the outside of your home should be seen as preventative maintenance; it can mean your home looks better for longer, and it can prevent serious and often costly problems from arising.
