What Louisiana Homeowners MUST Know Before Hiring an Exterior Cleaning Company
If you’re researching exterior cleaning for your home, you’ve likely seen two terms everywhere:
Soft Washing and Pressure Washing.
Many companies use them interchangeably.
Some intentionally confuse them.
And some don’t even know the difference themselves.
But choosing the wrong method can lead to damaged siding, ruined roofs, etched concrete, and wasted money.
This guide will clearly explain:
- What soft washing really is
- What pressure washing is designed for
- Which method is safest for your home
- Which surfaces require each method
- What Louisiana homeowners specifically need to consider
By the end, you’ll know exactly what to ask before hiring anyone.
What Is Pressure Washing?
Pressure washing uses high-pressure water—often ranging from 2,500 to 4,000 PSI—to blast away dirt, grime, and buildup from hard surfaces.
Pressure Washing Is Best For:
- Concrete driveways
- Sidewalks
- Patios
- Pool decks
- Some hard stone or masonry surfaces
When used correctly, pressure washing is extremely effective on durable, non-delicate surfaces.
The Risk of Pressure Washing
High pressure doesn’t discriminate.
If used incorrectly, pressure washing can:
- Etch concrete permanently
- Damage siding and paint
- Force water behind walls
- Crack wood fibers
- Shorten the lifespan of surfaces
This is why pressure should never be the default option for an entire home.
What Is Soft Washing?
Soft washing uses low-pressure water (similar to a garden hose) combined with professional cleaning solutionsdesigned to kill organic growth at the root.
Instead of blasting dirt away, soft washing treats the problem, then gently rinses it off.
Soft Washing Is Best For:
- House siding (vinyl, stucco, brick, Hardie board)
- Roofs (shingle, tile, metal)
- Gutters
- Fences
- Wood surfaces
- Delicate exterior materials
Why Soft Washing Is Safer
- Uses low pressure
- Prevents surface damage
- Eliminates algae, mold, and mildew at the source
- Keeps surfaces cleaner longer
This is why roof manufacturers and siding manufacturers recommend soft washing, not pressure washing.
The BIGGEST Difference Most Homeowners Don’t Realize
Pressure washing removes visible dirt.
Soft washing eliminates living organisms.
In Louisiana’s humid climate, the main enemy isn’t dirt— it’s:
- Algae
- Mold
- Mildew
- Bacteria
If those aren’t killed, they grow back fast.
That’s why many homeowners notice their house looks dirty again just months after a “pressure wash.”
Why Soft Washing Is Essential in Louisiana
Louisiana homes face unique challenges:
- High humidity
- Heavy rainfall
- Warm temperatures year-round
These conditions create the perfect environment for organic growth.
Common Louisiana Exterior Problems:
- Green algae on siding
- Black streaks on roofs
- Mildew under eaves
- Mold buildup on shaded walls
Soft washing doesn’t just clean these—it treats and prevents them.
Can Pressure Washing Damage a Roof?
Yes. Absolutely.
High pressure on a roof can:
- Strip protective granules from shingles
- Shorten roof lifespan
- Void manufacturer warranties
- Cause leaks
That’s why pressure washing should NEVER be used on asphalt shingle roofs.
Roof cleaning should always be done using low-pressure soft washing methods.
Why Some Companies Push Pressure Washing
Simple answer: equipment cost and speed.
Pressure washers are cheaper.
They’re faster.
And they require less training.
Soft washing requires:
- Specialized systems
- Knowledge of chemical ratios
- Understanding of surface materials
- More time and care
That’s why companies that invest in soft washing typically focus on quality over volume.

How Long Do Results Last?
This is where soft washing truly shines.
- Pressure washing: short-term cosmetic clean
- Soft washing: longer-lasting results because growth is killed
Many homeowners see months to years of cleaner surfaces when soft washing is done correctly.
How to Protect Yourself When Hiring a Cleaning Company
Before hiring anyone, ask:
- Do you soft wash homes and roofs?
- What PSI do you use on siding?
- Are your methods manufacturer-approved?
- Do you treat organic growth or just rinse it off?
- Are you insured for surface damage?
If a company says they “pressure wash everything,” that’s a red flag.
Final Verdict: Soft Washing vs Pressure Washing
| Surface | Best Method |
|---|---|
| House Siding | Soft Washing |
| Roofs | Soft Washing |
| Concrete | Pressure Washing |
| Patios | Pressure Washing |
| Fences | Soft Washing |
| Wood | Soft Washing |
The smartest exterior cleaning uses both methods appropriately.
