Exterior Surface Cleaning

Eliminating South Louisiana's Mold, Mildew & Algae Problem

South Louisiana's combination of heat, humidity, and rainfall creates near-perfect conditions for mold, mildew, algae, and organic staining to thrive on virtually every outdoor surface. Driveways that were clean a few months ago develop dark streaks. Patios and walkways grow slippery green algae films. Siding accumulates black mildew. Fences turn gray and dingy. This isn't a maintenance failure — it's simply the reality of living in one of the most humid climates in North America. Professional pressure washing is the most effective way to combat it.

Apex Grounds Co. provides professional pressure washing services for driveways, sidewalks, patios, pool decks, fencing, retaining walls, and exterior siding. We use commercial-grade pressure washing equipment calibrated to the appropriate pressure and flow rate for each surface type, combined with professional cleaning solutions that break down organic growth rather than just blasting surface dirt away. The result is a deeper, longer-lasting clean than rental equipment can achieve.

Our approach is surface-specific. Concrete driveways receive high-pressure treatment that scours away embedded oil stains, tire marks, and organic growth. Patios and pavers are cleaned at appropriate pressure to remove staining without dislodging joint sand. House siding and painted surfaces are treated with soft washing techniques — lower pressure combined with targeted cleaning solutions — to achieve a thorough clean without risking surface damage. Every job starts with a surface assessment so the right method is applied every time.

Surfaces We Clean

  • Driveways, sidewalks, and walkways
  • Patios, pool decks, and outdoor living areas
  • Fencing — wood, vinyl, and metal
  • House siding and exterior walls (soft wash)
  • Retaining walls, steps, and masonry

Our Process

How Pressure Washing Works

1

Surface Assessment

We assess each surface — material type, age, current condition, and type of soiling — to determine the correct pressure setting, nozzle configuration, and cleaning solution before any equipment is activated. This prevents surface damage and ensures optimal results.

2

Pre-Treatment & Wash

Heavily soiled areas and organic growth receive a pre-treatment of appropriate cleaning solution, which breaks down mold, algae, and staining at the molecular level before pressure is applied. This produces a thorough clean rather than just surface blasting.

3

Rinse & Inspection

All surfaces are thoroughly rinsed to remove cleaning solution residue, followed by a detailed inspection to confirm all staining and growth has been addressed. Any stubborn spots receive additional spot treatment before we call the job complete.

Why It Matters

Benefits of Professional Pressure Washing

Curb Appeal Restoration

Clean driveways, walkways, and siding restore the fresh, well-maintained appearance of your home — often making more visual impact than any landscaping improvement.

Surface Longevity

Mold, algae, and organic growth slowly degrade exterior surfaces over time. Regular washing extends the life of concrete, wood, siding, and painted surfaces, deferring costly repairs.

Safety Improvement

Algae and mildew growth on walkways, driveways, and pool decks creates dangerously slippery surfaces. Pressure washing removes these hazards and makes exterior areas safer for your family.

Pre-Paint Preparation

If you're planning to repaint exterior surfaces, professional pressure washing is the essential first step. Painting over mold or dirty surfaces leads to premature paint failure.

Property Value

A clean, well-maintained exterior is a key factor in buyer perception and appraisal outcomes. Regular pressure washing is one of the highest-ROI exterior maintenance investments you can make.

Healthier Environment

Mold and mildew spores on exterior surfaces can enter your home through doors, windows, and HVAC systems. Eliminating these colonies reduces indoor allergen load for your household.

Louisiana Humidity Makes Annual Washing a Necessity

With average relative humidity consistently above 70% and annual rainfall exceeding 60 inches, South Louisiana accelerates organic growth on outdoor surfaces faster than almost anywhere in the country. What might take 3-4 years to accumulate on a driveway in a drier climate can develop within a single season here. Mold spores, algae, and mildew thrive in our warm, wet conditions — and they're not just aesthetic problems. Organic growth gradually degrades concrete, traps moisture against siding, and creates genuine slip hazards on walkways and patios. Apex Grounds Co. recommends annual professional pressure washing for most South Louisiana properties, with semi-annual visits for highly shaded areas or homes near bodies of water where growth rates are even faster.

Frequently Asked Questions

Is pressure washing safe for all exterior surfaces?

Not all surfaces should be treated with the same pressure settings. High-pressure washing is appropriate for concrete driveways, brick pavers, and masonry. Softer surfaces like painted wood siding, stucco, certain fencing materials, and older wood decking require lower-pressure soft washing techniques to avoid damage. We assess each surface before selecting the appropriate pressure, nozzle, and cleaning solution to achieve results without causing harm.

How much does pressure washing cost in South Louisiana?

Pricing varies based on the size and type of surface being cleaned. Driveways, sidewalks, patios, and fencing are typically priced by the square foot, while house washing is usually priced by the linear foot of exterior perimeter. We provide a free on-site estimate so you get an accurate price for your specific project before any work begins. We never charge by the hour — you always know the full cost upfront.

How often should I have my property pressure washed?

In South Louisiana's humid subtropical climate, mold, mildew, algae, and organic staining can accumulate on exterior surfaces remarkably fast — sometimes within a few months of a previous cleaning. Most homeowners benefit from annual pressure washing of driveways and walkways, and semi-annual washing of house siding, patios, and fencing. Properties in heavily shaded or wooded areas often need more frequent treatment due to faster mold and algae regrowth.

Do you use eco-friendly cleaning solutions?

Yes. We use biodegradable, environmentally responsible cleaning agents that are effective against mold, mildew, algae, and organic staining without posing risks to surrounding landscaping, pets, or waterways. Given South Louisiana's proximity to wetlands, bayous, and sensitive ecological areas, we take our responsibility to use safe products seriously. We can provide product information upon request.

What is the difference between pressure washing a driveway versus washing a house?

Driveways and concrete surfaces can handle direct high-pressure water jets that blast away embedded staining, oil, and organic growth. House washing is a different process — soft washing uses lower pressure combined with specialized cleaning solutions to treat siding, eaves, and trim safely without forcing water behind cladding or damaging paint. Treating a house siding with the same high pressure used on concrete is a common mistake that can cause significant damage. Our team uses the correct method for each surface.

Will pressure washing remove black streaks on my roof?

Black streaks on roofs are caused by Gloeocapsa magma, a type of blue-green algae that spreads via airborne spores. We do not recommend pressure washing roof shingles, as high pressure can strip protective granules and void manufacturer warranties. Roof washing is a soft-wash specialty service using low pressure and algaecide solutions. Contact us to discuss soft roof washing as a separate service from standard pressure washing.

Can you pressure wash after a storm or hurricane?

Yes. Post-storm pressure washing is an excellent way to remove the mud, silt, organic debris, and flood residue that storms deposit on driveways, patios, sidewalks, and exterior walls. We frequently perform storm follow-up pressure washing as part of or immediately after storm debris cleanup service. Combining cleanup and washing in a single visit is efficient and cost-effective.

How long does a typical pressure washing job take?

A standard residential driveway and walkway cleaning typically takes 1-2 hours. Adding patio areas, fencing, or house washing extends the job accordingly — most full exterior property washings are completed in a half to full day. We schedule visits with adequate time to do the job properly rather than rushing, and we confirm the expected timeframe during your estimate so you can plan accordingly.
