What Are Those Black and Green Stains on My House And Why Won't They Wash Off?
Those black streaks are a living organism called Gloeocapsa Magma
The dark black or dark brown streaks running down your siding and brick are caused by Gloeocapsa Magma an airborne algae that thrives in Louisiana’s heat and humidity. It produces a dark pigmented sheath to protect itself from UV rays, which is why it looks so dark and why rain doesn’t remove it. It spreads from roof to walls to fence if not treated.
The green film is algae and it spreads fast in Acadiana's climate
Green buildup on siding, facia boards, and soffits is algae feeding on moisture trapped against your home. Lafayette’s tree canopy, humidity, and regular rain create perfect growing conditions. Once established, algae spreads across entire walls within a single wet season.
Mold and mildew go deeper than the surface they cause real damage
Unlike algae which sits on the surface, mold and mildew penetrate into porous materials like wood siding, painted surfaces, and mortar joints. Left untreated for more than one season, mold can cause paint failure, wood rot, and eventually structural damage to fascia boards and window frames.
My house looks dirty no matter how often I clean why does it keep coming back?
Because pressure washing with plain water only removes the visible layer it doesn’t kill the organism. Within weeks, the algae and mold regrow from spores left behind. The correct method is soft washing with a biodegradable biocide solution that kills growth at the cellular level. Results last 12–24 months, not 12–24 days

Real Lafayette Homes Before & After Our House Wash

- Our house wash process
Looking for House Washing Near You? Here's How Our Process Works
The best house wash near you is not just showing up with a pressure washer. Here is our precise 5-step process the reason our results last 12 to 24 months while everyone else needs re-washing every few weeks:
01
Free quote phone or on-site, no commitment
We quote most Lafayette homes over the phone based on square footage and siding type no site visit required to get a price. For larger or complex properties, we do a quick on-site walkthrough. Either way, you receive a firm, written price before we schedule. No estimates that grow into surprises.
02
Pre-treatment of outlets, fixtures and all landscaping
Before applying any cleaning solution, we tape off exterior electrical outlets, cover light fixtures, pre-wet every plant and shrub within 10 feet of the wash zone, and confirm all windows and doors are closed. Your property is fully protected before we touch the first wall this step alone separates professional house washing from amateur operators.
03
EPA-safe biocide solution applied at 40 to 80 PSI
We apply our biodegradable, EPA-safe soft wash solution at 40 to 80 PSI well below the pressure your garden hose produces on full blast. The solution penetrates the algae, mold, and mildew cell wall and kills the organism completely. It dwells on your exterior for 5 to 15 minutes depending on buildup severity before the rinse cycle begins.
04
Thorough low-pressure rinse, roofline to foundation
We rinse from the roofline downward in sections, flushing dead organisms, dirt, and detergent completely away. No streaking, no cleaning solution residue left on glass or trim, no chemical smell remaining when we leave. Every square foot is inspected before the rinse is complete.
05
Before and after photos sent you approve before we collect payment
We photograph every job before and after and send them to you on completion. If you are home, we do a full perimeter walkthrough with you. If you were not present, you receive photos before we request payment. You confirm the result meets your standard we do not collect until you are satisfied. No exceptions, no pressure.
Why We Soft Wash Your House Not Pressure Wash It
Every competitor in Lafayette offers “house washing.” Very few explain why soft washing is the only correct method for exterior walls. Here’s the truth:
| Factor | Soft washing (what we use) | High-pressure washing (wrong for siding) |
|---|---|---|
| Pressure used | 40–80 PSI (below garden hose) | 1,500–3,000 PSI |
| How it cleans | Chemical solution kills organisms at root | Physical force blasts surface only |
| Result longevity | 12–24 months before regrowth | 4–8 weeks before regrowth |
| Safe for vinyl siding? | Yes — no damage risk | No — dents panels, voids warranty |
| Safe for stucco? | Yes — no cracking | No — cracks substrate |
| Kills mold at root? | Yes — biocide solution | No — removes visible layer only |
| Safe for landscaping? | Yes with proper pre-wetting | Potentially damages plants |
The bottom line: high-pressure washing your house siding is like scrubbing a wound without antiseptic you remove what you can see, but the infection comes right back. Soft washing kills it completely.

Best House Washing Services in Lafayette, Louisiana FAQs
What is soft washing a house and is it better than pressure washing?
Soft washing uses very low water pressure (40–80 PSI) combined with a biodegradable cleaning solution to kill algae, mold, and mildew at the cellular level. Pressure washing uses high water pressure (1,500–3,000 PSI) to physically blast surfaces clean. Soft washing is significantly better for house siding because it kills the organisms rather than just removing the visible layer, gives results that last 12–24 months instead of a few weeks, and doesn’t risk denting vinyl panels, cracking stucco, or forcing water behind your siding.
How often should I have my house washed in Louisiana?
In Louisiana’s humid climate, most homes need a professional house wash once a year. Homes in heavily shaded areas, those near large oak or pecan trees, or homes with north-facing walls may benefit from washing every 8–10 months. After a professional soft wash, you can expect 12–24 months before significant algae or mildew regrowth — much longer than DIY pressure washing or garden hose cleaning.
Will house washing damage my plants or landscaping?
When done correctly by a professional, no. Before applying any cleaning solution, we pre-wet all plants, grass, flower beds, and shrubs within 10 feet of the wash zone. We use 100% biodegradable, EPA-safe solutions, and rinse all vegetation thoroughly after the job. We also redirect runoff away from root zones where possible. Amateur operators often skip these steps — professional crews know them as non-negotiable.
Can you soft wash a brick house?
Yes. Brick and mortar respond very well to soft washing with a biodegradable cleaning solution. We use medium pressure with a chemical dwell time to penetrate the porous brick surface and clean deep into the mortar joints. This removes Gloeocapsa Magma algae, mold, and mildew staining that makes brick look permanently darkened. The result is brick that looks like it was freshly laid.
How long does a house wash take?
A typical 2,000 sq ft home takes 2–3 hours from arrival to completion, including setup, pre-treatment of outlets and landscaping, solution application, dwell time, and rinsing. Larger homes (2,500–4,000 sq ft) take 3–4 hours. We give you a specific arrival window when booking so you know exactly when to expect us.
Do I need to be home when you wash my house?
No. For exterior house washing, many customers simply leave access to the property (gate code if applicable) and make sure windows and doors are closed. We send a text notification when we’re on our way and again when the job is complete, along with before-and-after photos. Payment is collected digitally after you approve the results — you don’t need to be present at any point.
Why does the green stuff keep coming back on my siding?
Because plain water pressure washing only removes what you can see on the surface — it doesn’t kill the algae or mold organism. The spores remain in the surface pores and in the surrounding air, and the green growth returns within weeks once moisture is present again. Professional soft washing uses a biocide solution that kills the organism at the cellular level. After a proper soft wash, most homeowners see 12–24 months before any meaningful regrowth.
Is house washing worth it before selling a home?
Absolutely. A professional house wash typically costs $250–$400 for an average Lafayette home and can add thousands to a home’s perceived value and listing price by dramatically improving curb appeal. Real estate agents consistently report that a clean exterior is one of the highest-ROI improvements a seller can make before listing. It also gives buyers a positive first impression and eliminates concerns about maintenance and mold that could trigger inspection negotiations.
How much does it cost to wash the outside of a house in Lafayette, LA?
Most Lafayette homeowners pay between $250 and $600 for a standard house soft wash on an average-sized home (1,500–2,500 sq ft). Smaller homes under 1,500 sq ft typically run $180–$300. Large homes or those with heavy algae buildup may run $400–$650. We provide a free, firm quote before scheduling — no surprise charges after the job.
