Pressure washing, whether with a high-pressure washer or a power washer, is a great way to clean your home without running water. High-pressure washers allow you to remove unwanted debris and mold from your siding in a matter of minutes. Most experts recommend pressure washing for homes that have shingle siding or vinyl siding, depending on the amount of mildew or mold buildup. It’s recommended to do this twice a year typically around fall and spring!
