Homeowners across St. Tammany Parish and the Hammond area often ask the same question:
“How often should I pressure wash my house?”
Because Louisiana has a warm and humid climate, homes here tend to develop algae, mold, and mildew faster than in many other parts of the country.
For most homes in areas like Slidell, Mandeville, Covington, Madisonville, Hammond, Ponchatoula, and Robert, exterior house washing is recommended every 12 to 24 months.
However, several factors can cause a home to need cleaning sooner.
Why Homes in Louisiana Get Dirty Faster
The climate across Southeast Louisiana creates the perfect conditions for organic growth on exterior surfaces.
The most common things that build up on homes include:
- Green algae on siding
- Mold and mildew
- Pollen buildup
- Dirt and environmental pollutants
Because humidity levels remain high for much of the year, these contaminants spread quickly across siding, brick, stucco, and painted surfaces.
That’s why pressure washing and soft washing services are very common throughout St. Tammany Parish.
Signs Your Home Needs Pressure Washing
Even if you are unsure how long it has been since your last cleaning, there are several easy signs to look for.
Green or Dark Stains on Siding
Algae growth is the most common reason homes need cleaning in Louisiana.
Dirty or Discolored Areas
If parts of your siding look darker than others, buildup may be forming.
Black Stains on Concrete
Driveways and sidewalks often develop dark staining caused by algae and organic growth.
Your Home Looks Dull
Sometimes the biggest sign is simply noticing your home doesn’t look as bright or clean as it once did.
The Difference Between Pressure Washing and House Washing
Many people use the term pressure washing to describe all types of exterior cleaning.
However, professional companies typically use different cleaning methods depending on the surface.
Pressure Washing
Used mainly for durable surfaces such as:
- Driveways
- Sidewalks
- Patios
- Concrete surfaces
Soft Washing
Used for more delicate surfaces like:
- Vinyl siding
- Stucco
- Painted surfaces
- Roof shingles
Soft washing uses specialized cleaning solutions and low pressure to safely remove algae and organic growth.

Regular pressure washing and house washing can provide several benefits for homeowners.

A freshly cleaned home instantly looks brighter and newer.
Protects Exterior Surfaces
Removing algae and mold helps prevent long-term damage to siding and other materials.
