Siding Cleaning by Material: Vinyl, Stucco, Wood, Brick & Fibre Cement
Serving Hamilton, Dundas, Burlington, Oakville, Stoney Creek & surrounding Ontario communities
Overview
Not all cladding should be cleaned the same way. Vinyl cracks under pressure, stucco is porous and holds residue, cedar raises its grain if it's over-wetted, and factory-coated fibre cement has published cleaning limits that high-pressure washing exceeds. This page is about matching the method to your siding material. If you want the whole exterior refreshed in one visit — siding plus soffits, fascia, trim and doors — our house washing service is the better fit; siding cleaning is the focused option when the cladding itself is what needs care.
What is the safe way to clean my type of siding?
Vinyl and aluminium: under 500 PSI with a biodegradable solution, rinsed top-down. Stucco and parging: the gentlest pressure, no spray into hairline cracks. Wood and cedar: short dwell time so the grain doesn't raise. Brick and fibre cement: chemical cleaning with a gentle rinse to protect mortar and factory coatings. Identifying the material first is what keeps the cladding — and its warranty — intact.
Benefits of Professional Siding Cleaning
Vinyl: Low Pressure, Never Blasted
Under 500 PSI with a biodegradable solution, rinsed top-down — the method vinyl manufacturers specify, so panels don't crack, warp, or take water behind them.
Stucco & Parging: Gentlest Setting
Porous surfaces get minimal pressure, no direct spray into hairline cracks, and a residue-free rinse so the texture doesn't streak or hold solution.
Wood & Cedar: Shorter Dwell Time
A controlled application and quick rinse lift algae and grey weathering without raising the grain, fuzzing the surface, or lifting stain.
Brick & Fibre Cement: Mortar-Safe
Brick joints and coated Hardie board both suffer under high pressure. We clean chemically and rinse gently so mortar and factory finishes stay sound.
Aluminium: No Dents, No Chalking
Aluminium dents easily and oxidizes. Low-pressure washing removes chalky film and organic growth without denting panels or dulling the finish.
Keeps Warranty Conditions Intact
Several manufacturers exclude damage from pressure washing and require mild-detergent low-pressure cleaning. We clean to those published methods.
Our Siding Cleaning Process
Siding Material Identification
We confirm what your cladding actually is — vinyl, aluminium, stucco, wood, brick, or fibre cement — and set pressure and solution strength to that material.
Landscape Protection
We pre-wet and protect all plants, garden beds, and landscaping.
Solution Application
We apply our biodegradable soft wash solution to kill algae, mould, and mildew.
Dwell Time
We allow the solution to work into biological growth for maximum effectiveness.
Low-Pressure Rinse
We rinse with low-pressure water, removing all cleaning solution and biological matter.
Final Inspection
We inspect all surfaces and address any remaining spots before completing the job.
Siding cleaning vs. house washing — which do you need?
Siding cleaning (this page)
Focused on the cladding itself, with pressure and solution matched to your material — vinyl, stucco, wood, brick, fibre cement or aluminium. The right pick when the siding is what's dirty, or when your material needs a specific approach.
House washing
The whole exterior in one visit: siding plus soffits, fascia, eaves, trim, doors and light fixtures. The right pick for a full seasonal refresh or before listing a home.
Why Professional Siding Cleaning Is Better Than DIY
The risk with siding is almost never the dirt — it's using the wrong pressure or the wrong chemistry on the wrong material. High pressure cracks vinyl, dents aluminium, drives water behind cladding, opens mortar joints, fuzzes cedar, and is excluded from several manufacturers' warranty coverage. Chlorine-heavy mixes at the wrong dilution can also spot stucco and lighten stained wood. Knowing which setting and solution each cladding needs is the whole job, and it's why we identify the material before any water touches the house.
