Pressure Washing & Surface Prep
The critical step most painters skip — we never do
Professional Pressure Washing in Alberta
Paint is only as good as the surface beneath it. That's why thorough cleaning and surface preparation is the foundation of every KERNI project — and a service we offer as a standalone for any property owner who wants results that last. Our professional pressure washing removes years of accumulated grime, algae, mold, mildew, and chalking paint residue. Combined with proper sanding, priming, and masking, we ensure maximum adhesion and a finish that performs for years. This is the step that separates a one-season paint job from a decade-long one.
What's Included
Everything you should expect from a professional job — all included, no surprises.
How It Works
Our proven process — from first contact to final walkthrough.
Site Assessment
We inspect the surfaces to be washed, identify problem areas (heavy mold, oil stains, etc.), and determine the right pressure and technique for each surface type.
Pre-Treatment
Mold-heavy or heavily soiled surfaces receive a pre-treatment spray of appropriate cleaning solution, applied and allowed to dwell before washing.
Pressure Washing
We systematically wash all specified surfaces using commercial-grade equipment, adjusting pressure and tip selection to match each surface without causing damage.
Post-Rinse & Inspection
All surfaces are fully rinsed. We inspect for any remaining staining or biological growth and re-treat as needed before completing the service.
What Affects the Cost
Every project is different. These are the key factors that determine your final quote — there are no hidden fees, and you receive a detailed written breakdown before any work begins.
- Total surface area (square footage)
- Type of surfaces (vinyl siding, stucco, wood, concrete)
- Degree of biological growth or soiling
- Whether pre-treatment chemicals are needed
- Whether this is standalone or pre-paint prep

“We had our driveway and the exterior of our stucco house pressure washed before painting. The amount of stuff that came off the stucco was shocking — I had no idea how dirty it was. The painting after looked dramatically better than the last time when they didn't bother to properly clean first.”
Common Questions
Everything you need to know before booking pressure washing.
Yes. Every exterior painting project includes a full pressure wash as part of the preparation phase. We never paint over dirty surfaces.
In the wrong hands, yes. We adjust pressure, tip selection, and distance based on the surface type. Stucco, older siding, and wood require lower pressure and soft-wash techniques — we know the difference.
