Soft Wash Services Built for Central Louisiana

Humidity, tree cover, and long summers make Cenla one of the hardest climates in the country for exterior surfaces. Here’s exactly what we do to fix it — safely, and for years at a time.

Service 01

Roof Soft Washing

If your roof has black streaks running down the north or shaded side, you don’t have dirt — you have a living colony of Gloeocapsa magma algae feeding on the limestone filler in your shingles. Left untreated, it shortens roof life by 20–30% and traps heat on hot days.

We use the soft-wash method recommended by the Asphalt Roofing Manufacturers Association (ARMA): a biodegradable cleaning solution applied at low pressure (about the force of a garden hose) that kills algae at the root. No walking the roof, no high-pressure lifting of shingles, no damage.

What’s included

  • Pre-wet of landscaping and plants surrounding the home
  • Application of ARMA-approved soft wash solution to the entire roof surface
  • Gentle dwell time so the solution kills algae, mold, and lichen at the root
  • Thorough low-pressure rinse
  • Final walkthrough with you

What to expect

Most residential roofs take 2–4 hours. You’ll see immediate improvement, but algae spots can continue to fade for up to two weeks as the solution fully kills the remaining organism. Results typically last 4–6 years in the Central Louisiana climate.

Works on

Asphalt shingle (architectural and 3-tab), metal roofs (standing seam, ribbed), tile roofs, low-slope and flat roofs.

Red flags to avoid from other contractors

  • Pressure washing your roof. This voids most shingle warranties and can lift granules. Walk away.
  • “Power washing” promised at a super-low price. Often means someone who will blast your roof with high-pressure water to save time.
  • No pre-wet of plants. A good crew spends 15 minutes protecting your landscaping before any solution is applied.

Service 02

House Washing

Vinyl siding turns green. Brick turns gray. Stucco grows black streaks below the soffits. In Cenla’s humidity, any exterior surface becomes a feeding ground for algae and mildew within a couple of years.

Our house wash removes years of buildup in a single visit without damaging paint, caulk, or mortar. We use the same soft-wash approach as the roof service — biodegradable solution, low-pressure application, thorough rinse.

What’s included

  • Pre-wet of landscaping and shrubs
  • Low-pressure soft wash of siding, soffits, trim, fascia, shutters, and gutters (exterior face)
  • Hand detailing of trouble spots around doors, downspouts, and gutter runs
  • Rinse of siding and immediate surrounding concrete/walkways
  • Final walkthrough

Works on

Vinyl siding, Hardie/fiber-cement siding, brick, stucco, EIFS, painted wood, cedar shake (approach varies — ask us).

What’s the cost?

Pricing depends on home size, siding type, and degree of buildup. A typical 2,000 sq ft single-story Central Louisiana home falls in a predictable range — call us with your address and we’ll give you a price in under five minutes.

Red flags to avoid from other contractors

  • Using pressure on vinyl siding. Forces water behind panels, rots wall sheathing.
  • Using chlorine-only solutions. Kills surface growth but doesn’t clean properly. You’ll see streaks in a month.
  • No landscaping protection. A proper soft wash has near-zero plant impact when done right.

Service 03

Concrete & Driveway Cleaning

Concrete is porous. That’s why mildew, oil, tire marks, and rust settle deep into the surface and won’t come out with a garden hose. We use a surface-cleaner attachment (a spinning-jet tool that distributes pressure evenly across the concrete) paired with pre-treatment chemicals that lift embedded organic growth.

Result: driveways, sidewalks, pool decks, and patios that look five years younger — without the zebra stripes you get from a handheld pressure wand.

What’s included

  • Pre-treatment of the concrete with a soft wash solution to kill mildew and algae
  • Hand-scrub of heavy oil stains and rust
  • Surface-cleaner pass across the entire concrete area for an even clean
  • Final rinse
  • Optional: post-treatment application to slow re-growth

Works on

Residential driveways, sidewalks, patios, pool decks, garage floors, commercial utility pads, loading bays, fuel pads.

What to expect

Most driveways take 1–2 hours. You’ll see the transformation in real time. Results typically last 1–2 years depending on shade and tree litter.

A note on sealing

We don’t seal concrete as a standard service, but we can connect you with a local pro who does if you want to lock in the clean.
