House washing in St. Catharines, the soft-wash way.

A house wash is the highest-impact thing you can do for curb appeal in a single afternoon. Here is what soft washing is, why it beats pressure washing on an exterior, what gets cleaned, and what it costs in St. Catharines.

What soft washing is

Soft washing uses low pressure, roughly the force of a garden hose, paired with a cleaning solution that kills the algae, mould, and mildew at the root. High-pressure washing blasts the surface, which can drive water behind siding, etch brick, and pit stucco. The safe pressure for a given siding is manufacturer- and product-specific, so check your own siding manufacturer's guidance rather than assume one rule covers every product. Soft washing does a deeper clean and the result lasts longer because the organic growth is treated, not just knocked off. Most soft-washed homes go a couple of years between washes; a pressure-rinsed wall with no solution often sees the algae return within months.

What gets cleaned

• Vinyl and aluminum siding. The most common St. Catharines call. North and shaded walls go green first and clear without the risk of water intrusion.
• Brick and stucco. Cleaned at a pressure that will not etch the mortar or pit the stucco.
• Soffits, fascia, and eaves. The grimy edges up high that make a clean wall still look tired.
• Exterior windows and gutter faces. An easy add-on while the equipment is already set up, so the whole exterior matches.

Driveways and flatwork: a different tool

Hard horizontal surfaces are the exception to the soft-wash rule. Concrete driveways, walkways, and interlock can take a rotating surface cleaner at higher pressure, which spins the spray evenly across the whole pad for a uniform finish instead of the stripe marks a bare wand leaves. Interlock should be cleaned without blowing out the joint sand, with re-sanding available afterward, and concrete can be sealed after cleaning to slow re-staining. Driveway cleaning is usually the most affordable exterior job and bundles well with a house wash.

What house washing costs in St. Catharines

No verified Niagara or Ontario figure for what this work costs exists in any government, association, or other authoritative source, so this guide publishes none. The way to learn what your job costs is a written, itemized quote from a local contractor, and a second one itemized the same way so the two can be compared line by line.

Roof streaked too? Shingle manufacturers caution against pressure washing asphalt roofs, so a soft wash is the safer way to clean shingles, and the walls and roof can be done in one visit.
