Guelph-KW Soft Washing

Green-Black Streaks on Your Siding? Soft Washing Across Guelph & the Tri-Cities

High-pressure washing can crack vinyl and force water behind siding panels. Soft washing uses low pressure and an algae-killing solution instead — safer for your home's exterior and it lasts longer than a straight pressure rinse.

Why Soft Washing Beats Pressure Washing for Siding

The instinct to crank up the pressure to clean faster is exactly what damages siding — vinyl panels can crack or blow inward at close range under high PSI, water can get forced behind panels into wall cavities, and mortar joints on older brick homes can erode under repeated high-pressure blasting.

Soft washing solves this differently: an algae- and mildew-killing solution does the actual cleaning work, applied and rinsed at low pressure. It's safer for the surface and the results last longer, since the algae is killed at the root rather than just knocked loose temporarily.

Frequently Asked Questions

What's the difference between soft washing and pressure washing?

Pressure washing relies on high water pressure alone to blast dirt off; soft washing uses a cleaning solution to kill algae/mildew at the root, applied at low pressure so it's safe for siding, painted wood and mortar joints that high pressure can damage.

How much does house soft washing cost?

A single-storey home typically runs $250–$450; two-storey homes are $350–$600, depending on square footage and how much algae/mildew buildup there is.

Is soft washing safe for vinyl siding?

Yes — it's specifically the recommended method for vinyl, since high-pressure washing at close range is what cracks or blows out vinyl panels.

Will it damage my landscaping?

Crews manage runoff and rinse plantings if the solution contacts them — let us know about sensitive gardens when booking.

How long do results last?

Typically 1–2 years before algae streaking starts to return, longer on sunnier, drier-facing walls than shaded ones.
