House washing is a top-to-bottom cleaning of your home's exterior — siding, gutter faces, rooflines — to clear off everything a Boise year leaves behind. But the method matters. We soft wash. Instead of hammering every surface with high-pressure water, we pair a low-pressure rinse with professional-grade, plant-safe cleaning solutions that break down the growth itself and carry it away.
That difference is a big deal on a house. High-pressure water in the wrong hands drives moisture up behind siding, cracks mortar, and peels paint the high-desert sun has already spent years drying out. Soft washing cleans just as well — usually better — without putting any of that at risk. And because the solutions kill algae, mold spores, and mildew at the root, the clean actually lasts instead of creeping back by fall.
Here's why we reach for the soft-wash rig every time a house is involved:
| Soft Washing (what we do) | High-Pressure on Siding | |
|---|---|---|
| Pressure on the surface | Low pressure, gentle on paint and trim | High pressure that can crack mortar or strip paint |
| How it cleans | Cleaning solutions kill algae and mildew at the root | Blasts off the visible layer only. Growth returns faster |
| Risk to your home | No water forced behind siding. Safe for stucco and wood | Water can be driven up under siding and into walls |
| How long it lasts | Longer, because the organic growth is removed at the source | Shorter, because surface regrowth is common |
Boise sits in high desert: intense summer sun, cold winters, dusty spring wind off the foothills, and sprinklers running half the year to keep the lawns alive. Your siding catches all of it. The south side fades and chalks under the sun. The north side stays damp after every morning watering — and that shaded, damp strip is exactly where mildew and algae move in.
Around here, it usually shows up as:
Those black streaks are almost always a cyanobacteria called Gloeocapsa magma. It feeds on the limestone filler in roofing materials and creeps down across the siding over time. Up on rooflines and gutters, moss and algae add weight and slow your drainage. Down low, where sprinkler splash keeps things damp, mildew discolors the siding first — then starts working on the paint if it sits long enough.
And then there's the dust. Spring wind pulls fine grit off the foothills, and late summer stacks wildfire haze on top of it. Both leave an oily film that rain can't rinse away on its own. A regular wash keeps that film from settling in as permanent staining.

Every house gets the same four steps, in the same order, because it works:
We walk the property first — checking surface types, noting existing wear, and flagging anything that needs a careful hand.
A plant-safe cleaning solution goes on and starts breaking down algae, mildew, and staining before we rinse a thing.
Low pressure, section by section, lifting the loosened grime off siding, trim, and gutter faces without stressing any of it.
A thorough rinse, a second look at every wall, and one more walk-around with you after a final walkthrough.
A clean house looks great from the street, sure. But a regular wash also pays you back in quieter ways:
We're based in Boise. Not a franchise, not a call center dispatching whoever happens to be nearest. When you call Pressure Wash Boise, you get a crew that knows the difference between North End wood siding and a brand-new vinyl build out past Ten Mile.
Our routes cover the full Boise metro, including Meridian, Eagle, Nampa, and Garden City. Meridian's newer subdivisions are heavy on vinyl and painted stucco, which stay sharp with a yearly wash against the valley dust. Eagle's older custom homes lean toward wood and brick, and those want a slower, more careful hand. Either way, it's familiar ground for us.
Our cleaning solutions are plant-safe, and we rinse nearby landscaping before and after the wash to look after your beds and lawn. Pricing on a house wash comes down to how much siding you have and how far the algae and streaking have gotten. Call, and you get a number before any work begins.
We soft wash houses across the whole Boise metro — Meridian, Eagle, Nampa, and Garden City included. Vinyl, stucco, wood, or brick, the low-pressure method clears off the mildew, algae, and high-desert dust while your paint and finish come through untouched.
One call does it — tell us what needs cleaning and your number's ready before we hang up. No form to fill out.
Call (208) 842-1167Estimate over the phone, real person See your priceWhat sets the price, on the home pageThe three things Boise homeowners ask about most before they book:
No. Soft washing exists for exactly this reason. Low pressure, solution strength matched to vinyl, wood, stucco, or brick, and nothing forced up behind the siding. Your paint stays right where it belongs.
Yes. The solutions are plant-safe and go on at low pressure. We soak your garden beds down before and after the wash so any overspray gets diluted, and we just ask that dogs and cats hang out inside while we work.
A house wash is priced on the square footage of siding and how much buildup is on it. Give us the address and we estimate it up front, then that price is set before the first drop of solution goes on. You know your number before we start.
Straight answers to what Boise homeowners ask us most.
It depends on square footage, siding type, and how much buildup we're working through. Two-story homes and bigger footprints take more time, product, and setup. Call, and you get your estimate before any work begins.
Soft washing pairs low-pressure water with professional cleaning solutions that break down algae, mildew, and dirt, then rinses it all away gently. Standard pressure washing leans on high-pressure water alone. For a house exterior, soft washing is the better tool — it cleans deeper, and it won't chew up siding, paint, or mortar joints the way high pressure can.
Every one to two years covers most homes around Boise. If your lot has heavy tree cover, a shaded north wall, or spots where the sprinklers hit the siding every morning, once a year is smarter. And if you can already see green or black growth, it's time — no matter what the calendar says.
Our soft wash process is built for painted and coated surfaces. We match pressure and solution strength to whatever your home is wearing — vinyl, wood, stucco, or brick. High pressure in the wrong hands can strip paint; low pressure done right doesn't. If we spot damage that was there before us, we point it out during the walk-around so there's no confusion later.
Yes, both, and we clean them all the time. Stucco needs a light touch and the right solution so it doesn't etch, and we work on both traditional and synthetic finishes. Brick and mortar take to soft washing well — we lift off algae, efflorescence (that chalky white mineral haze), and years of airborne staining without wearing down the mortar joints.
Plan on two to three hours for a typical single-story Boise home, setup to final rinse. A larger two-story or a place with complicated rooflines and lots of trim can run three to five. We keep a steady pace, but we never rush the rinse.
Not for the wash itself. We just ask that someone's around at the start so we can walk the house together and hear about anything you want us to watch. After that, most folks go on with their day and come home to clean siding. We'll let you know when we wrap up.
The outside faces, yes — that's part of every full house wash. Gutter exteriors pick up black streaks over the years from oxidation and algae, what the trade calls tiger striping, and it takes a specific treatment to lift. Clearing leaves and debris out of the inside of the gutter channel is a separate service, so ask about it when you call.
We use plant-safe solutions at low pressure and treat your landscaping like it's our own. We ask that pets stay inside or away from the work area during the wash. Garden beds near the house get wetted down before and after so any overspray is diluted, and we steer runoff away from anything planted.
You'll see it while we work — each section we rinse looks noticeably brighter than the one beside it. The full result shows once the siding dries, usually a couple of hours in Boise's dry air. Any stubborn biological staining that didn't rinse completely keeps fading over the next two to three weeks as the sun finishes the job.
Yes. We cover the whole Boise metro, including Meridian, Eagle, Nampa, and Garden City, and we run routes through Ada and Canyon Counties all the time. Getting to you is no trouble. Reach out and we'll find a time that fits your neighborhood.
It can help more than people expect. Mold spores, pollen, and algae collect on siding, especially around windows, vents, and doors where air moves in and out of the house. Wind and everyday comings and goings stir those particles back up right at your entry points. Washing the exterior clears that biological load away, which can take some pressure off the allergy-prone folks in the house.
Almost always a hardy airborne algae called Gloeocapsa magma. It settles wherever there's shade or moisture and feeds on organic material in siding and roofing. High pressure alone can't beat it, because the black layer you see is just its protective shell. The solutions we use in soft washing break the organism down at the root, so it's actually gone — not just knocked back for a season.
If anything sits right against the walls we'll be washing, sliding it back a few feet before we arrive helps a lot. We're glad to move light items ourselves during the job, but heavy furniture and big planters travel better with a head start. And if there's anything you'd like covered and protected from spray, just say so.
