How Often Should You Get Your House Washed in Wisconsin

For most Madison-area homes professional house washing every one to two years is the right cadence. Signs your house needs washing now include green or black streaks on siding mold or mildew on north-facing walls siding that feels slippery or chalky and visible road salt residue near the foundation. Homes under heavy oak maple or pine trees accumulate sap pollen and organic debris faster than open-lot homes. North-facing walls stay wetter longer creating ideal mold conditions. Vinyl and painted wood siding bond algae quickly while homes near busy roads collect exhaust film. Spring from April through June is the most popular time for house washing in Madison because winter road salt ice melt and organic buildup peak by March. Washing in spring reveals any winter damage to siding or trim. Fall washing from September through October removes summer pollen bird droppings and mold before the exterior gets wet and cold for winter. The Total Wash Co. uses professional soft-wash technique that kills mold and algae at the root rather than just surface removal giving results that last significantly longer than pressure washing alone.
