South Portland homes, from the Willard Beach cottages to the in-town neighborhoods, pick up algae and mildew from the damp coastal air. We soft wash houses across the city and keep the siding looking right.
The fix for green and black growth isn’t force, it’s chemistry. We soft wash: a cleaning solution laid down at low pressure that kills the algae, mildew, and mold at the root rather than just blowing the surface off. A surfactant in the mix helps it cling and penetrate, and once it’s done its job we rinse the siding clean. It’s safe on vinyl, wood, and paint because the pressure stays low, and it lasts longer than a pressure-wash because dead growth doesn’t come right back.
Coastal humidity feeds growth on shaded walls, and homes near the water get it faster. A soft wash every year or two keeps it clean.
