Vinyl is the most common siding on Albany homes, and it's also the material most often damaged by the wrong cleaning method. Panels that have spent fifteen Capital Region winters outside go brittle, and high pressure cracks them, forces water up behind the courses, and cuts caulk at the seams.
City lots drain slowly, mature maples drop tannin-heavy leaf litter all fall, and plow salt off New Scotland and Delaware Ave gets tracked right onto walkways.
We clean vinyl the way the manufacturers specify: low pressure, a professionally diluted detergent that kills algae and mildew at the root, dwell time, hand detailing where the growth is heaviest, and a top-down rinse. The color comes back and it stays clean for years instead of weeks.
