Pressure Washing
Experience the pinnacle of professional power washing services. We employ unique equipment and cutting-edge processes that ensure a safer approach and an unmatched level of effectiveness for your home's exterior.
PNW Surfaces Need Professional Care
In the Pacific Northwest, your driveway, patio, walkways, and siding face a constant assault from moisture, organic growth, and mineral deposits. The region's 72+ inches of annual rainfall combined with mild winters create year-round conditions for black algae stains, green moss, and slippery biofilm on every hard surface around your home.
DIY pressure washers from the hardware store can strip paint, gouge wood, etch concrete, and force water behind siding — causing more damage than the dirt they remove. Velocity Cleaning Systems uses calibrated commercial equipment with the precise combination of pressure, flow rate, and eco-friendly pre-treatments engineered for each surface type.
The result? Surfaces that look brand new without a single scratch, gouge, or stripped finish. We service homes across Snoqualmie, North Bend, Issaquah, Sammamish, Bellevue, Kirkland, and the greater Puget Sound area.

What We Clean
Every surface around your home has different tolerances and needs a tailored approach. Here's how we handle each.
Concrete & Pavers
Driveways, sidewalks, and patios get a hot-water pre-treatment to break down oil stains and black algae, followed by surface cleaning that leaves uniform, streak-free results.
Wood Decks & Fences
Low-pressure wash with wood-safe solutions that remove grey oxidation and green growth without splintering or stripping. Prep for staining included on request.
Vinyl & Composite Siding
Gentle pressure with mildew-killing pre-soak that eliminates the green and black streaks PNW homes are known for, without voiding your siding warranty.
Stone & Brick
Calibrated pressure that cleans deep into porous surfaces without eroding mortar joints. We remove moss, efflorescence, and years of buildup safely.
Why “Damage Free” Matters
Every year we get calls from homeowners who hired a cheap pressure washing service and ended up with etched concrete, splintered deck boards, or water damage behind their siding. Here's what sets our approach apart.
Surface-Specific PSI
We calibrate pressure for each material — 500 PSI for painted siding, 3,000+ PSI for concrete. One size never fits all.
Pre-Treatment Chemistry
Eco-friendly solutions do 80% of the work before water ever hits the surface, reducing the pressure needed and preventing damage.
Proper Technique
Our technicians maintain correct nozzle distance and angle to avoid fan marks, etching, and the 'tiger striping' that amateurs leave behind.
Landscape Protection
We pre-soak and protect plants, cover sensitive areas, and use biodegradable chemicals that break down harmlessly within 30 minutes.
