In Charleston’s humidity, siding doesn’t stay clean long, you see the mildew and algae creeping up shaded walls all over the peninsula and the surrounding neighborhoods. We soft wash homes across the city, historic and new, and bring them back without harming the house.
Here’s why blasting it is the wrong move. A pressure washer hits the wall with 3,000 PSI or more, and on siding that force cracks panels, strips paint, and drives water up behind the material. Soft washing does the opposite: we apply a cleaning solution at low pressure, softer than a garden hose, and let the chemistry work. It kills the mildew, mold, and algae down at the root, while a surfactant keeps it clinging to the siding long enough to penetrate, then we rinse it clean. Because the growth is killed and not just knocked loose, it stays gone a lot longer, which matters in this climate.
The Lowcountry’s heat and humidity are a perfect breeding ground for mildew and algae, and salt air off the harbor doesn’t help. Soft washing clears it and, because we kill it at the root, it stays clean far longer in this climate.
FAQ
My siding goes green and black every year. Why so fast here? The humidity. The Lowcountry climate grows mildew and algae quickly, especially on shaded sides. We kill it at the root so it comes back slower.
Is soft washing safe on a historic or painted home? Yes. It’s low pressure and safe for painted, wood, and stucco surfaces, and we test a spot first on anything delicate.
