Pressure washing a parking lot usually runs about $8 to $20 per parking space, according to HomeGuide’s 2025 commercial cost guide, or roughly $0.10 to $1.00 per square foot depending on how much oil and grime is on the surface. A small strip-center lot and a large retail lot can land thousands of dollars apart, so the useful question for a property manager is what drives the number on your particular lot.
In Kenner, that answer often starts with traffic. Lots along the busy commercial corridors near the airport collect road film, oil drips, and tire marks faster than a quiet office lot, and Gulf humidity keeps that grime damp long enough to bond. Below, we cover the published price ranges, what changes a quote, and the wash-water question every manager should ask before any crew starts.
How much does it cost to get a parking lot cleaned?
HomeGuide’s commercial pressure washing guide (last updated October 2025) gives these national figures:
- Parking lots: $8 to $20 per parking space
- Commercial surfaces in general: $0.10 to $1.00 per square foot
- Hourly rates: $50 to $150 per hour
- Flat fees: $200 to $3,000 or more, depending on size and complexity
HomeGuide notes that the per-space price accounts for the extra time for oil removal and tire marks, and that large lots may qualify for volume pricing. Our own parking lot cleaning service page gives a rough guide of $0.40 to $0.80 per square foot, or $60 to $100 an hour, for lots like the ones we see. Treat both as a starting point, not a quote.
How much does it cost to powerwash a parking lot?
In most quotes, “power washing” means pressure washing with heated water, and on a parking lot that heat does real work. Oil and grease don’t respond to pressure the way loose dirt does. They have to be broken down by heat and a degreasing solution before water can carry them off, which is why a cold-water rinse can leave a lot looking clean while wet and stained once it dries.
That extra step costs more per square foot, and it’s usually worth it on any lot with a history of oil drips. Our post on the benefits of using hot water for pressure washing explains the difference in plain terms.
We handle lots two ways. Sweeping clears loose dirt and debris before it gets ground into the asphalt. Pressure washing with hot water and a cleaning solution matched to what’s on the surface goes after the oil stains, fuel residue, and sticky grime that sweeping can’t move.
What changes the price of a parking lot cleaning in Kenner?
- Size. Square footage or space count sets the base.
- Oil and stain load. Spots under parked cars and at entrances take pre-treatment and more passes.
- Timing. Work scheduled overnight or before opening, so the lot is empty, can affect the price.
- Extras on the same visit. Sidewalks, drive-thru lanes, and dumpster pads are often bundled.
Kenner lots along the main corridors deal with a greasy road film on top of ordinary dirt, and that film comes back on a schedule set by traffic instead of weather. We think that’s the main reason a busy Kenner lot needs attention more often than a lot a few streets back. If you manage several surfaces, ask about our sidewalk and walkway cleaning, drive-thru lane cleaning, and dumpster pad cleaning in the same quote.
What should a parking lot cleaning quote include?
A useful quote spells out the area being cleaned, in square feet or parking spaces, and says whether the price is per space, per foot, per hour, or flat. It should say whether hot water and a degreaser are part of the job, since that’s the difference between a lot that looks clean wet and one that stays clean dry. It should also list what’s excluded, like sidewalks, curbs, or the dumpster pad, so two bids are comparing the same work.
When bids land far apart, the gap usually comes from scope. One company may be pricing a quick cold-water rinse while another is pricing pre-treatment of every oil spot. Ask each one to walk you through exactly what they’ll do on your Kenner lot before you compare totals.
Where does the wash water go?
This is the question we’d ask before hiring anyone. Water rinsed off a parking lot can carry oil, fuel residue, and detergent, and a storm drain is not a place to dispose of it. Under the federal stormwater program, the EPA defines an illicit discharge as “any non-stormwater discharge to the storm sewer system,” and local governments that run storm systems must prohibit those discharges through local ordinances.
What that means for a specific Kenner lot depends on the local rules where the property sits, so check with the city or parish office that handles stormwater for your address. When you’re comparing bids, ask each company how it plans to handle the water on your site, and get the answer in writing. Our older post on oil spots, line striping, and drains in New Orleans parking lots covers why drainage matters for the lot itself.
How often should a Kenner parking lot be cleaned?
It depends on traffic and what the lot is used for. A restaurant or auto-service lot with steady oil drips needs more frequent cleaning than a medical office lot that empties every evening. Our post on setting a commercial cleaning schedule by foot traffic walks through how to pick an interval.
Weather plays a part too. Kenner’s frequent afternoon storms leave standing water in low spots, and silt and organic staining settle where that water dries. Shaded edges under trees and along the north side of a building can grow a slick green film, which is a slip risk for customers walking in from their cars.
Does a clean parking lot matter for safety?
A lot is the first thing a customer walks across, and oil and algae make a surface slick, especially after rain. Cleaning won’t fix a pothole or a drainage problem, but it removes the film that makes wet pavement worse underfoot. Our post on wet surfaces and public access during commercial work covers how to keep people safe while the work is going on, since a freshly washed lot is wet for a while.
In our experience, managers who schedule cleaning around their quietest hours get the least disruption and the best result, because an empty lot gets cleaned edge to edge instead of around parked cars.
What else do Kenner property managers ask?
Can you work overnight or before opening?
Ask when you call. Lots are best cleaned empty, and we’ll talk through timing that keeps your entrances open.
Do you clean line striping?
Cleaning lifts the grime sitting on top of the paint, which can make stripes look brighter. It doesn’t repaint faded lines.
Is a written quote free?
Yes. Ask for a written quote after a walk of the lot, since size, stains, and access set the real price more than any published range.
