House Washing in Northern Virginia

Northern Virginia's humidity, tree cover and long pollen season are hard on siding. NovaBlastWash house washing removes the green film, black streaks and gray grime that build up on homes across Reston, Ashburn, Fairfax, Arlington and the rest of NOVA.

What house washing removes

• Green algae and black mildew streaks — most common on shaded and north-facing walls
• Dirt, pollen and road dust that dulls siding color
• Cobwebs and insect residue around eaves, lights and windows
• Grime on trim, soffits, shutters and entry doors

Why house washing uses low pressure

Siding is not concrete. High pressure can force water behind vinyl panels, crack brittle or older siding, etch soft surfaces, strip paint and damage window seals. Professional house washing — often called soft washing — uses low pressure with appropriate cleaning solutions that break down organic growth, followed by a thorough rinse. It cleans more completely than pressure alone, and the results tend to last longer because growth is removed rather than just knocked off the surface.

When to schedule a house wash

Spring and early fall are the most popular times in Northern Virginia. A spring wash removes the winter grime and the heavy yellow-green layer of tree pollen; an early-fall wash gets your home looking sharp before the holidays and before colder weather sets in. House washing is also one of the most effective things you can do before listing a home for sale or before repainting.
