Pressure Is a Tool, Not the Whole Answer
Green film on the north side of the house, black streaks down the siding, a deck that's slick enough to be genuinely dangerous in January — that's the standard Clark County growth cycle. Our mild, wet winters are ideal for algae, moss and mildew, and they come back every year whether or not anyone deals with them.
The mistake most homeowners make is reaching for maximum pressure. High PSI will strip the paint off siding, etch lines into concrete, splinter cedar decking, and drive water up under lap siding where it has no way out. On most surfaces the right approach is soft washing: low pressure plus a detergent that kills the organism, then a rinse. The cleaning is chemical, not mechanical — which is why the results last longer than a blast job.
We match the method to the surface. Real pressure on concrete and masonry where it's appropriate, soft wash on siding, roofs and painted wood. We wet down landscaping before and after, and we use detergents that break down rather than sitting in your beds.

Signs It's Time to Call
If any of these sound like your home, it's worth a free look before the problem grows.
Green or black growth on the shady side
North-facing walls and anything under a fir tree go first. Left alone, that growth holds moisture against the surface and shortens the life of the paint underneath.
A deck that's slippery when wet
That slickness is a biofilm, and it's a real fall risk from October through April. It's also the first sign the wood is staying wet long enough to start breaking down.
Moss carpeting your roof or gutters
Roof moss lifts shingle edges and lets water underneath. Soft washing handles it without the shingle damage that comes from scraping or high pressure.
Concrete that's gone gray-green
Driveways, walkways and patios collect algae and lichen that make an intact slab look neglected. This is one of the most dramatic before-and-afters in the business.
You're about to paint or stain
New paint over a dirty, chalky or mildewed surface will not bond. A proper wash and full dry-out is the single most important prep step on any exterior job.
You're listing the house
A washed exterior, clean driveway and bright walkway change the first photo and the first impression, for a fraction of what any other curb-appeal project costs.
How the Job Runs, Start to Finish
No mystery, no surprise invoices. Here's exactly what happens after you reach out.
Walk the property & pick the method
We look at every surface and decide what gets pressure and what gets soft washed. Painted siding, cedar and roofs almost never get high pressure from us.
Protect plants and openings
Landscaping gets soaked down before we start so it isn't taking up detergent, outlets and fixtures get covered, and windows and doors get checked for gaps.
Apply, dwell & agitate
Detergent goes on and is given time to work. That dwell time is what actually kills the algae and moss — rushing straight to the rinse is how a wash job comes back in three months.
Rinse, inspect & re-rinse landscaping
Clean rinse from the top down, a walk-around with you to catch anything missed, and a final rinse of the beds and lawn around the work area.
What Affects the Price
Washing is priced by square footage and by how heavy the growth is — a house washed every other year costs less than one that hasn't been touched in a decade. Here's what we're pricing against.
Talk numbers: (360) 718-6290Square footage and stories
More surface takes more time and more product. Two- and three-story walls need extended reach equipment or staging.
How heavy the growth is
Light seasonal dirt is one pass. Established moss, lichen and years of buildup need more product and more dwell time.
Surface type
Concrete tolerates real pressure and cleans fast. Cedar, painted siding and roofing need the slower, gentler soft wash approach.
Stain removal
Oil, rust and tannin stains on concrete need specific treatments beyond a standard wash, and some are improvable rather than fully removable — we'll tell you which yours is.
Access and water source
Tight side yards, steep lots, and fenced areas take longer to set up. We work off your spigot unless there isn't one.
Bundling
House, driveway, walkways and deck in one visit costs meaningfully less than booking each separately, since setup happens once.
