Soft Washing in Des Moines, IA
When Des Moines homeowners call us for soft washing, the conversation usually starts with the same thing: green algae on north-facing siding, mildew streaks, and dingy concrete. We've worked on enough Des Moines properties — Ingersoll Park, Merle Hay, Sherman Hill — to know what causes those problems here and how to actually fix them.
How We Approach Soft Washing in Des Moines
Every Des Moines soft washing bid we send is built off an in-person walkthrough — never a Zillow photo or a phone estimate. That's the only way to catch the site-specific stuff (grade, access, existing hardscape, tree roots) that turns a "simple" soft washing project into a five-figure change order for other crews.

Local Notes: Soft Washing in Des Moines
The north-facing side of nearly every Des Moines house grows green algae within a couple of years — it's the humidity, the shade under mature oaks, and the way the wind sits in older Beaverdale and Drake blocks. Pressure washing that siding is exactly how you drive water behind vinyl and lap-siding gaps. We see the damage on houses that got the wrong wash.
Soft washing uses a low-pressure biocide application that kills the algae and mildew at the root, then rinses clean. Safe on painted trim, vinyl, aluminum, brick, stucco, and stained wood. We tarp landscape beds, rinse plants before and after, and stay well inside safe pressure limits. Concrete, decks, and roofs are separate scopes — we quote each honestly.
Common Soft Washing Problems We See in Des Moines
These are the issues Des Moines homeowners call us about most — and what actually causes them.
Growth that returns in weeks
Rinsing off the visible layer without killing the organism means it is back before the end of the season. Treating at the root is what buys you years instead of weeks.
Green and black growth on the north side
Nearly every Des Moines house grows algae on its shaded elevation. Humid summers, morning dew, and limited sun let it colonize vinyl, painted trim, and stucco within a couple of seasons.
Pressure-washing damage
High pressure drives water behind lap siding, strips paint, etches soft brick, and forces moisture into wall cavities. We are regularly called to Des Moines homes on century-old Beaverdale-brick bungalows, Drake-area four-squares, mid-century ranches near Merle Hay, and modern infill in the East Village that were damaged by a well-meaning wash.
Roof streaking
Those black streaks on asphalt shingles are gleocapsa magma, a cyanobacteria. It holds moisture against the shingle and shortens roof life — and it cannot be pressure-washed off without destroying the granules.
Our Soft Washing Process in Des Moines
Exactly what happens from the first call to the final walkthrough at your Des Moines property.
- 1
Surface assessment
We identify the substrate — vinyl, painted wood, brick, stucco, composite, shingle — and match the solution strength and technique to it. Different surfaces get different treatments.
- 2
Protect the landscape
Beds and sensitive plantings around your Des Moines home are pre-wetted and tarped where needed, and rinsed again afterward. Plants are the most common casualty of careless washing.
- 3
Low-pressure application
A biocide solution is applied at low pressure so it dwells on the surface and kills the algae, mold, and mildew at the root rather than just knocking the top off.
- 4
Dwell and rinse
The solution is given its working time, then rinsed clean with controlled low pressure. Nothing gets blasted, nothing gets driven behind the siding.
- 5
Inspection walk
We walk the house with you, hit any missed spots, and point out anything we noticed — failing caulk, damaged trim, or a downspout aimed at the wall.
Why Des Moines Homeowners Need Soft Washing Done Right
Curb appeal in Des Moines is a practical concern, not vanity. A washed exterior reads as a maintained house to buyers and appraisers, and removing biological growth genuinely extends the life of paint, shingles, and sealed wood. It is one of the cheapest exterior improvements available on a per-dollar basis.
Central Iowa humidity is why exterior growth is so persistent in Des Moines. Warm, wet summers followed by long damp shoulder seasons give algae ideal conditions, and Des Moines is Iowa's capital city, a mix of historic urban neighborhoods, riverfront districts, and dense established suburbs split by the Des Moines and Raccoon Rivers. Shaded blocks near Fairgrounds and South of Grand hold moisture the longest, which is why the north and east elevations always go first.

Soft Washing FAQ — Des Moines, Iowa
Honest answers from local soft washings serving Des Moines and Central Iowa.
What makes soft washing in Des Moines different from the rest of the metro?▾
Des Moines has its own quirks — river-bottom lots near the Des Moines and Raccoon Rivers, steep older neighborhoods south of Grand, eroding clay banks, and flat post-war grids — frequent basement-water and grading issues, plus century-old Beaverdale-brick bungalows, Drake-area four-squares, mid-century ranches near Merle Hay, and modern infill in the East Village. That changes how we approach soft washing here. Humid Iowa summers grow algae on every shaded surface, and no two Des Moines yards look the same — a 1920s Beaverdale lot needs a completely different plan than a flat South Side ranch, so our Des Moines jobs reflect that local reality.
How much does soft washing cost in Des Moines, IA?▾
Des Moines homeowners generally invest $300 to $1,500+ for soft washing, depending on square footage, materials, and site prep. We break down every line item in writing so there's no "surprise change order" halfway through the job.
How long does soft washing take in Des Moines?▾
Plan on Half day to 1 day for a Des Moines soft washing job. That includes prep, install, cleanup, and a final walkthrough. If your project is time-sensitive (an event, a sale, a closing date), tell us up front — we build the schedule around it.
What materials do you use for soft washing in Des Moines?▾
We use biodegradable, plant-safe surfactants and low-pressure rinse equipment — completely safe for Des Moines landscapes, pets, and sensitive surfaces. If a lower-cost material makes sense for your Des Moines project, we'll say so. If it doesn't, we'll say that too — the goal is honest specs, not upselling.
Are you licensed and insured in Des Moines?▾
Insurance-wise, we're covered end-to-end for Des Moines projects: liability, workers' comp, vehicle. That's non-negotiable on our side — we won't step onto a property without it, and you shouldn't hire anyone who does.
Do you offer free estimates in Des Moines?▾
Des Moines homeowners get a free on-site estimate, a written itemized quote, and time to think it over. No same-day pressure, no "today only" discounts, no games.
Do you clean concrete and decks too?▾
We do, using the right pressure and method for each surface. Concrete driveways and walks, paver patios, and wood decks each get treated differently — we quote them individually rather than as one flat exterior number.
Is soft washing safe for my siding?▾
Yes — that is the point of it. Soft washing uses low pressure and a cleaning solution rather than force, so it will not drive water behind vinyl laps, strip paint, or etch brick and stucco the way high-pressure washing does on Des Moines homes.
How long do results last?▾
Because we kill the algae and mildew at the root rather than rinsing the surface, most Des Moines homes stay visibly clean for two to three years. Heavily shaded north elevations under mature trees may need attention sooner.
Will the solution hurt my plants?▾
Not with proper protection. We pre-wet the beds, cover sensitive plantings, and rinse thoroughly afterward. We have washed hundreds of homes with mature landscaping and treat your beds as part of the job.
Can you clean my roof?▾
Yes. Roof cleaning is a separate scope using an even gentler application, and it removes the black streaking without dislodging granules. Never let anyone pressure-wash an asphalt roof in Des Moines or anywhere else.
