House Washing in South County St. Louis
Green streaks, dark discoloration, a home that just looks older than it should — usually it’s buildup on the surface, not the siding itself. Here’s how soft washing fixes it safely.
Real South County job — algae and oxidation lifted with a low-pressure soft wash.
If your home has started developing green streaks, dark discoloration, spider-web buildup, or simply looks older than it should, the problem may not be the siding itself. In most cases it’s years of accumulated dirt, algae, mildew, pollen, and organic growth on the exterior surfaces.
Professional house washing removes that buildup and restores a cleaner look — without the expense of repainting, replacing siding, or major exterior work. We provide house washing and soft washing across South County St. Louis with one simple philosophy: use the safest method possible, price it transparently, and tell you the truth about what cleaning can and can’t do.
What is house washing?
House washing cleans exterior surfaces to remove algae, mildew, mold, dirt, pollen, spider webs, organic staining, and general environmental buildup. Many homeowners assume it means blasting siding with high pressure — but most modern homes are better served by a soft washing process built for exterior surfaces.
What is soft washing?
Soft washing uses specialized cleaning solutions with low-pressure application to remove organic growth and staining. The goal isn’t maximum pressure — it’s maximum cleaning with minimal risk. It’s commonly used on:
- Vinyl siding
- Brick homes
- Stucco
- Fiber cement siding
- Painted surfaces
- Soffits and fascia
- Trim
For most South County homes, soft washing gives safer, longer-lasting results than traditional high-pressure cleaning.
Signs your home needs washing
Green streaks on siding
One of the most common signs of algae growth.
Dark areas on the north side
Surfaces that get less sun stay damp longer and develop growth faster.
Spider-web buildup
Especially around soffits, trim, and exterior lighting.
Dingy appearance
Many homeowners notice the house simply isn’t as bright as it used to be.
Black staining
Usually algae and environmental buildup accumulating over time.
Why South County homes develop exterior staining
Neighborhoods like Oakville, Mehlville, Concord, Crestwood, Sunset Hills, and Affton have mature trees, established landscaping, shaded lots, moisture retention, and north-facing exposures — ideal conditions for algae and mildew. Because it builds gradually, most homeowners don’t notice until they compare photos from a few years back.
What house washing can remove
- Algae — green staining common on vinyl siding
- Mildew — dark discoloration in shaded areas
- Dirt — general environmental buildup
- Pollen — especially in spring and early summer
- Spider webs — easy to overlook, very visible once gone
- Surface staining — many organic stains respond extremely well
What house washing cannot fix
Honest answer: not every exterior problem is a cleaning problem.
House washing will not repair faded siding, peeling paint, damaged trim, rotten wood, structural issues, or warped siding. If cleaning isn’t likely to make a meaningful difference, we’ll tell you before you spend money.
Why homeowners choose soft washing over high pressure
Many people search for “pressure washing” when what they actually need is soft washing. High pressure can damage siding, force water behind materials, strip paint, leave visible marks, and increase repair costs. Soft washing removes the source of the staining instead of just blasting the surface — for most homes, the safer approach.
Typical house washing costs
Every property is different, but most South County homes fall within these ranges:
| Home type | Typical price |
|---|---|
| Small ranch | $250–$400 |
| Average home | $350–$600 |
| Large two-story | $500–$900+ |
Pricing depends on home size, accessibility, amount of buildup, number of stories, and surface materials.

Is house washing worth the money?
In many cases, yes — it’s often one of the highest-impact exterior improvements available short of a renovation. Homeowners regularly notice improved curb appeal, brighter siding, cleaner trim, and reduced staining. The key is realistic expectations: house washing can make a dramatic difference, but it can’t make a 30-year-old exterior look brand new.
