Exterior Soft-Washing

Pressure washing is not the right tool for any residential exterior. High pressure damages vinyl siding, forces water behind cladding, strips painted surfaces, and can void manufacturer warranties.

Exterior soft-washing uses low pressure combined with professional, environmentally safe cleaning chemistry to remove algae, mould, mildew, and organic staining safely — without any of that risk.

Richardson Clean uses soft-washing as the standard approach for exterior house cleaning in Windsor-Essex. It produces better results on biological staining than pressure washing, and it's safe for vinyl, brick, stucco, wood, EIFS, and painted surfaces. The chemistry does the work. The water rinses it away.

What Soft-Washing Treats

Soft-washing is effective against algae, mould, mildew, lichen, and general organic buildup — the green, black, or grey staining that accumulates on siding, fencing, concrete, and exterior surfaces over time. It also treats Baudoinia compniacensis (whiskey fungus), the black sooty growth common on properties downwind of the Hiram Walker distillery in Walkerville, Riverside, and East Windsor.

The Process

Professional cleaning solution is applied to the exterior surface at low pressure and allowed to dwell — the chemistry breaks down and kills the biological growth at the root and emulsifies dust, dirt and grime. The surface is then rinsed thoroughly. Unlike pressure washing, which blasts the surface off, soft-washing kills the organisms eating away at your surfaces. Regrowth is significantly slower as a result.

Surfaces We Clean

Soft-washing is appropriate for vinyl siding, brick and mortar, stucco, EIFS, wood siding, fencing, concrete, driveways, patios, decks, and rooflines. If you're not sure whether your surface is suitable, ask — we'll give you a straight answer.

Windsor-Essex Environmental Considerations

Properties in Windsor-Essex face two specific staining challenges that most other Ontario cities don't. Iron oxide fallout from Zug Island across the Detroit River embeds into glass and siding, producing a hazy rust-coloured contamination that standard cleaning won't shift.

Whiskey fungus from the distillery facilities coat surfaces downwind with a black crust that requires biocidal treatment to address properly. Richardson Clean is familiar with both and equipped to treat them.

How Often Should You Soft-Wash?

Most Windsor-Essex homes benefit from an exterior soft-wash every two to five years. Properties with heavy tree cover, north-facing walls, or proximity to the Detroit River, Lake St Clair, or distillery may need more frequent treatment. We'll give you an honest assessment when we quote but if it looks dirty - it's time for a clean!
