Frequently Asked House Washing Questions

Soft washing cleans your siding with a low-pressure rinse and a cleaning solution rather than with force. Pressure washing relies on the water itself to knock dirt loose, which works on concrete and does real damage to siding, paint, and window seals. Soft washing does the opposite. The solution kills the algae and mildew at the root, then a gentle rinse carries it off. The result lasts longer, because the growth is dead rather than just knocked down, and nothing gets forced up behind the siding.

Unlike pressure washing, which uses high-pressure water to clean surfaces, soft washing relies on low-pressure application and gentle cleaning solutions. This method is safer for delicate surfaces like siding, roofs, and painted areas.
