Many contaminants can collect on your home’s exterior, some man-made and some natural. Things such as mold, mildew, and algae are natural contaminants while pollutants like car and factory emissions are man-made. You wouldn’t think car emissions would make your house dirty but we wash several buildings regularly that are located near heavy traffic areas and a black filth washes off the buildings every time. The same results occur for houses near railroad tracks or an airport.

The natural contaminants such as mold, mildew, and algae will naturally collect on most anything that is exposed to the elements. Black mildew is usually the first to show followed by green algae. This most often occurs on the north facing side of a house or building where there is the least amount of sun exposure.

Cleaning your home’s exterior surfaces is important in maintaining it’s appearance and value. Neglect is probably the biggest factor in decreased curb appeal and property value. If you never washed your vehicle, you can image how eventually it would ruin the appearance and value of it. On the other hand, keeping it clean and well maintained ensures you’ll get the most out of it when it’s time to sell. Your home is no different and it’s most likely your largest investment.

As we’ve mentioned before, having your home’s exterior professionally cleaned is probably the biggest bang for your buck when it comes to home improvement. For no more than a few hundred dollars you can potentially up your home’s curb appeal and value by thousands.
