Professional Pressure Washing
in Seattle & the Eastside
One contractor for every exterior surface on your property. We match the method to the material — pressure where it belongs, soft wash where it does not — and do the whole job right.
Why the Pacific Northwest Needs Regular Pressure Washing
Seattle and the Eastside have a cleaning problem that most of the country does not. The combination of coastal moisture, mild temperatures year-round, and dense tree canopy creates ideal conditions for moss, algae, lichen, and mildew to establish on every horizontal and shaded surface. It is not seasonal. Moss grows in winter. Algae runs in summer. By the time most homeowners notice, the growth is well established.
The direct cost of neglect is visible: a driveway covered in moss, siding streaked with algae, gutters backing up from debris. The indirect cost is less obvious. Moss traps moisture against surfaces and accelerates deterioration. Algae on a roof is the precursor to moss taking hold at the granule level. A deck that is not cleaned and sealed every couple of years starts to grey and crack from sustained moisture cycling.
Regular exterior cleaning is maintenance, not cosmetics. It extends the life of every surface it touches and prevents the kind of repairs that are genuinely expensive when they finally show up.
We clean everything — from driveways and decks to siding and roofs — using the right method for each surface. Concrete takes pressure. Roofs take chemistry and low pressure. Wood takes low pressure and a brightener. We do not use one setting for everything.
How a Full-Property Clean Works
Most properties have several surfaces that need attention — and the right order and method for each one matters.
Walk the Property & Scope the Work
We assess every surface, note what it is made of, and identify what growth or staining is present. That determines the method, the chemicals, and the time required. We do not start spraying until we know exactly what is in front of us.
Protect Plants, Vehicles & Drainage
Landscaping is pre-wetted and protected, vehicles are moved or covered, and we position to manage runoff responsibly — especially important on properties near Puget Sound tributaries.
Start from the Top
Roof or gutters first, then siding, then ground-level surfaces. Working top-down keeps everything that falls off a higher surface from dirtying a surface we just cleaned.
Match the Method to the Surface
High pressure for concrete and masonry. Low pressure and chemistry for siding, wood, and roofing. Soft wash for surfaces that cannot take force. The right tool at each step.
Rinse, Inspect & Walk the Property
Full rinse across all surfaces, then a walk-through so you can see the result and raise anything you want us to look at before we pack up.
Every Surface We Clean
One contractor, every exterior surface — residential and commercial:
Driveways & Concrete
High-pressure washing removes moss, algae, oil staining, and years of traffic grime from concrete, asphalt, and pavers.
House Wash & Siding
Vinyl, Hardie, painted wood, stucco, and brick siding soft washed to remove algae, mildew, and dirt without damaging the surface.
Decks & Fences
Wood decking and fencing cleaned at low pressure with brightening chemistry to restore color and prepare for staining or sealing.
Roofs
Moss, algae, and black streaking treated with soft wash — chemistry and low pressure only, to protect shingles, tiles, or metal.
Gutters
Interior gutter clearing and exterior whitening to remove black algae streaks and debris buildup from the fascia.
Commercial Surfaces
Parking lots, building exteriors, loading docks, dumpster pads, and commercial concrete — scaled for business timelines.

Growth killed at the root and spore level stays off significantly longer than surface-only rinse cleaning.

They did the whole property — driveway, siding, deck, and gutters. It looked like a different house. The driveway alone was worth the entire price.— Sandra K., Kirkland, WA · Full Exterior Cleaning
Pressure Washing Cost in Seattle
Pricing depends on what surfaces are included, their size and condition, and whether we are cleaning one surface or the full property. Full-property bundling is significantly better value than single-surface visits, and we price it that way. We provide itemized, transparent quotes before any work begins.
Surfaces & Square Footage
The scope — which surfaces and how large — sets the base price. Larger properties and more surfaces naturally take more time and materials.
Growth Severity
A lightly-maintained property cleans faster than one with established moss, heavy algae, or years of traffic staining.
Bundling
Cleaning multiple surfaces on one visit (driveway, siding, deck, gutters) is the most cost-effective way to maintain your property.

Frequently Asked Questions
What surfaces can you pressure wash?
Concrete driveways, sidewalks, and patios. Brick and block walls. Vinyl, Hardie, and painted siding. Wood decks and fences. Pavers and flagstone. Gutters and downspouts. Roofs treated with low pressure only. If you have a surface that needs cleaning, tell us what it is and we will tell you honestly whether pressure is the right tool and what the right settings are.
What is the difference between pressure washing and soft washing?
Pressure is PSI — the force of the water. Soft washing is a low-pressure approach that uses cleaning chemistry to do the work instead of force. Concrete and masonry can take high pressure. Roofs, painted surfaces, and vinyl siding cannot — those need soft washing, where pressure is kept low enough to rinse rather than strip. We use the right method for the surface, not one setting for everything.
How often should I pressure wash my home's exterior?
For most Pacific Northwest homes, once a year is a reasonable baseline — usually in late spring before summer, or in early autumn before the wet season. Homes under heavy tree cover, north-facing surfaces, and properties near standing water will show more growth and benefit from more frequent attention. We will tell you what we see and how often makes sense for your property specifically.
Do you offer any kind of maintenance plan?
Yes. Our Annual Power Plan covers scheduled cleaning visits across your priority surfaces so nothing gets to the point of needing a full restoration. Regular cleaning is cheaper than neglect in a climate that grows moss and algae aggressively — we can walk you through what a plan looks like for your specific property.
Can you clean my entire property in one visit?
Usually, yes — driveway, siding, deck, fences, gutters, and roof treatment can all be bundled on one visit, which is the most cost-effective way to maintain a property. We will scope the work, give you a clear estimate, and block the right amount of time to do it properly.

Pressure Washing Across Seattle & the Eastside
Exterior cleaning needs vary significantly across the region. Dense tree canopy in Woodinville, Issaquah, and Sammamish means faster moss and algae growth on every north-facing surface. Waterfront and near-water properties in Kirkland, Renton, and Mercer Island deal with more algae and mineral staining. Older Seattle and Everett neighborhoods have more established growth on brick and concrete that has been left for years. Newer suburban construction in Bothell and Redmond tends to be lower-growth but still benefits from annual maintenance.
