How Much Does Pressure Washing Cost in South Louisiana in 2026?

Pressure washing cost in South Louisiana runs $150 to $400 for a typical single-family home exterior. Most homeowners pay between $200 and $350 for a full house wash, with driveways, patios, and fences on either side of that range depending on size and grime level. Prices in New Orleans, Baton Rouge, and Lafayette run a little below the national average, thanks to competitive local markets.

Average Pressure Washing Costs by Job Type

Prices vary by surface, square footage, and how dirty things are. Here are the ranges most homeowners see in South Louisiana:

• Full house exterior wash: $200 to $400. A 1,500 to 2,500 square foot home falls right in the middle of this. Most companies use soft washing for siding, which cleans without damage.
• Driveway (two car): $150 to $300. Concrete driveways are the bread and butter job and clean up fast, so they are some of the cheapest per square foot.
• Patio, deck, or pool surround: $125 to $300. Stained or algae-covered concrete takes longer and costs more than a lightly dirty surface.
• Fences: $150 to $350 depending on length and material.
• Roof wash (soft wash): $250 to $500. South Louisiana roofs pick up heavy black algae streaking, and a proper soft wash costs more than a driveway because it is done carefully at low pressure.
• Whole property package (house plus driveway plus walkways): $350 to $600. Bundling is the best per-item deal.

What Drives the Price Up or Down

Size of the area. Almost every pressure washer prices by square footage, so a sprawling ranch costs more than a compact shotgun home.

Condition of the surface. Light dusting is quick. Heavy algae or years of buildup require pretreatment chemicals and dwell time, which adds $50 to $150.

Surface type. Concrete can take high pressure and cleans fast. Siding, stucco, and painted surfaces need soft washing, which is gentler and slower. Fragile or historic materials take the longest and cost the most.

Access. Steep driveways, fenced yards with no gate access, or second stories needing ladder work all add time and money.

Season and demand. After hurricane season or during spring listing season, demand spikes and prices can creep up 10 to 20 percent. Off-peak winter months sometimes come with discounts.

Add-ons. Gutter brightening, rust stain removal, or a post-wash driveway sealer usually adds $50 to $150 per item.

Money-Saving Tips

1. Bundle services. Washing the house, driveway, and walkways in one visit is cheaper per surface than scheduling them separately. Ask for a package price.
2. Get three quotes. House washing prices Lafayette LA homeowners see can vary by $100 or more between companies for the exact same job. Quotes are free.
3. Do the prep yourself. Move patio furniture, potted plants, and vehicles out of the way before the crew arrives. You avoid a prep fee and the job goes faster.
4. Ask about off-season scheduling. Late fall and winter are slower months for pressure washers in Louisiana. A polite "do you offer any off-peak pricing" can save you real money.
5. Maintain between washes. A quick rinse of shaded, algae-prone areas once a season stretches the time between professional washes.
6. Check what the quote includes. Some low quotes skip the detergent pretreatment that actually kills mold at the root. A wash that just blasts off the surface dirt will look dirty again in a month, and you will pay twice.

When to Call a Pro vs. DIY

DIY works for: small, flat concrete areas like a short walkway or a small patio, provided you rent or borrow a machine and know how to use it. Rental runs about $75 to $100 per day plus detergent.

Call a pro when: the job involves a roof, any second-story surface, painted siding, or a surface with heavy mold or algae. Pros carry commercial machines, use the right detergents, and know which surfaces need soft washing. A homeowner with a rental pressure washer can etch streaks into concrete, strip paint, or push water behind vinyl in about five minutes.

Rule of thumb: if the job is bigger than a single patio, or higher than you can reach standing on the ground, hire it out.

The South Louisiana Factor: Mold, Algae, and Humidity

This is what makes pressure washing in South Louisiana different from almost anywhere else in the country. Our humidity, shade from live oaks, and long warm season mean mold, algae, and mildew grow on everything: siding, fences, driveways, roofs, even cars parked under trees.

The green slime on north-facing siding and the black streaks on roofs are usually an algae that feeds on the limestone filler in asphalt shingles. High pressure destroys shingles, so the only correct method is soft washing, a low-pressure application of algaecide detergent. Any roofer pressure washing your roof with high pressure is damaging it. Ask every bidder which method they use.

How often should you wash? In most of the country, a house wash every two or three years is fine. In South Louisiana, plan on once a year for the house exterior, and once a year for shaded driveways. Roof soft washes last two to three years if done properly. Homes near the bayou or under heavy tree cover may need it more often. Regular washing is not just cosmetic here. Algae and mold hold moisture against siding and shingles, which shortens their lifespan and can become a repair bill instead of a maintenance bill.
