Vinyl Siding Soft Washing
Vinyl siding is durable against weather but surprisingly vulnerable to high-pressure washing at close range — panels can crack, and water forced behind them can lead to hidden moisture issues in the wall cavity. Soft washing avoids all of that: the cleaning solution does the work, low pressure just rinses it away.
Shaded, north- and east-facing walls in older neighbourhoods with mature tree cover are the most common problem spots for the greenish-black algae streaking that plain water won't remove.
- Low pressure — won't crack panels or force water behind siding

Vinyl Siding Soft Wash FAQs
Will the cleaning solution fade my siding colour?
No — the solutions used are formulated for vinyl and rinsed off thoroughly; they don't bleach or fade the material the way harsh undiluted chemicals could.
How long does a house take?
Most homes are done in 1–3 hours depending on size and access.
Do you clean gutters and downspouts too?
Gutter cleaning is a related but separate service — see our gutter-cleaning partners; siding soft washing focuses on the wall surfaces, trim, soffits and fascia.
Can this be done in cooler weather?
Soft washing can be done in most non-freezing conditions, though spring through fall is the most common and practical window.
