Patio Cleaning for Flagstone in Virginia
In Virginia, concrete has to deal with summer mildew and winter salt and freeze-thaw cycles. Annual cleaning and a sealer every few years help it last.
Spring pollen season in Virginia coats houses, cars, screens and patios in a yellow-green film, and pollen gives mildew something to feed on. Many homeowners book their wash after pollen season ends so the house stays clean longer.
Red clay soil is common in parts of Virginia. Rain splashes it onto the bottom of the siding, walls and walkways, and its iron-rich color can stain light surfaces. It usually needs a dedicated clay or rust cleaner rather than pressure alone.
