01ConcreteOne Machine, One Even Clean
Concrete is the one surface we do clean with real pressure, and the tool matters more than the force. A rotary surface cleaner spins two jets under a hood, so the whole slab gets the same pass. That is how you avoid the stripes a wand leaves behind.
This specialist service is available through our broader pressure cleaning services in Wilmington.
We pretreat oil and rust, clean the field, edge with a wand and then post treat so dark mildew returns slowly in our damp climate. The job fits homeowners, landlords and anyone with a slick walk. Two photos of the slab get you a first range.
What We Clean on Your Property
A visit can cover every hard surface around the house, or just the one that bothers you most.
- Driveway and apronWhere the car sits, and where oil drips.
- Front walk and sidewalkShaded runs that stay damp and slick.
- Steps and curbsEasy to overlook, and quick to turn green.
- Patio and pool deckWet, sunny spots that grow algae fast.
- Garage floor and entryTire marks and dust.
- Spot treatmentOil and rust, handled before the main wash.
Why Concrete Gets Slick and Dark Here
Wilmington sees about 60 inches of rain across roughly 122 rainy days a year, per the National Weather Service. Humidity runs near 74 percent. Shaded concrete rarely dries all the way, so mildew and algae settle in.
Irrigation water can leave orange rust, and local well water may be part of that story. Slick concrete is also a slip risk on walks and steps, which makes cleaning a safety job as much as a looks job.
How a Concrete Job Moves
Our order is the same on every slab, but the details change with the stains.
- Sweep and clearLeaves, grit and loose debris come off first, and cars and furniture move out of the way.
- Pretreat stainsOil gets a degreaser, rust gets a rust remover, and both get time to work.
- Surface cleanThe rotary cleaner makes steady passes across the field.
- Edge with a wandCorners and borders get hand detail.
- Post treatA light treatment slows regrowth on shaded spots.
- Rinse to the lawnWashwater goes to the grass, not toward the storm drain.
- PhotosSame angle as the first shot.
Concrete Surfaces We Clean
Each surface has its own habits, and the table shows how we treat them.
| Surface | What We Watch For |
|---|---|
| Driveways | Oil, tire marks, rust, mildew |
| Sidewalks and walkways | Shade, algae, slick spots |
| Patios | Furniture rings, leaf stains, pollen |
| Pool decks | Sunscreen film, slick algae |
| Pavers | Weeds in joints, washed out sand |
| Garage floors | Tire marks, dust, spills |
| Steps | Moss in the corners |
Sidewalk cleaning Wilmington NC homeowners ask about is usually a front walk that has gone green. Walkway pressure washing for those narrow runs is quick, and it makes the biggest difference at the entrance.
Concrete Cleaning Cost Wilmington NC Homeowners See
Square footage sets the base price. Oil, rust and sealing are add ons, and a quick look at photos fixes the range.
| Job | Typical Range |
|---|---|
| Driveway | $100 to $250 |
| Sidewalk and front walk | $75 to $150 |
| Patio | $100 to $250 |
| Pool deck | $150 to $350 |
| Rust or oil spot treatment | $25 to $100 per area |
Bundles help. Pressure washing driveway and sidewalk work in one visit saves a trip. Concrete sealing after cleaning is available as an add on, and it can change the total.
Surface Cleaner or Wand: The Difference You Can See
Most streaky driveways were cleaned with a wand alone. The table shows why we reach for the hood first.
| Rotary Surface Cleaner | Wand Only | |
|---|---|---|
| Finish | Even across the slab | Lines and lap marks |
| Speed | Faster on big areas | Slow and tiring |
| Splash | Held under the hood | Sprays walls and siding |
| Best use | Driveways, patios, decks | Edges, steps, tight corners |
Protecting Lawns, Drains and Paint
Concrete work sends a lot of water around. These habits keep it where it belongs.
- Washwater kept out of storm drainsThe City of Wilmington illicit discharge ordinance, effective September 15, 2009, says commercial washing with soaps must collect wastewater. We take the spirit of that rule on every job.
- Cars movedNothing parked on the slab while we work.
- Siding near the driveRinsed so splashes do not leave marks.
- Lawn edgesProtected and rinsed after.
Why Is My Concrete Turning Black, Green or Orange
Each color tells you what is growing or staining the slab.
- BlackMildew. It likes shade, damp spots and slow drainage.
- GreenAlgae. It grows where water sits and sun cannot reach.
- OrangeRust from irrigation water or fertilizer. A rust remover works here, and pressure does not.
- Tan or redSoil that splashes up during storms.
- Dark spotsOil, tire marks and leaf tannin.
Concrete cleaning without stripes starts with the right machine, and the colors fade as the surface dries. A post treatment helps slow the black from coming back.
What Else Pairs With Concrete Work
Concrete is rarely the only dirty thing. Here is what pairs well on the same visit.
- Driveway focusOil, tire marks and a long drive.
- Patio and pool deckSlick surfaces behind the house.
- PaversWeeds in joints and loose sand.
- Rust stainsOrange arcs on walls and slabs.
- House washingSiding that matches the clean drive.
- Parking lotsCommercial slabs get the same machine.
Sealing, Slip Risk and What Concrete Can Take
Cleaning removes growth, but it does not change the concrete itself. Some owners want a sealer on top afterward to slow stains and brighten the color. We can talk it through before the visit, and we will tell you if the slab is too worn or cracked to benefit.
Slip risk is the quiet reason many people call. A wet walk with a green film is how people fall, especially on steps and pool edges. Once the film is gone, shoes grip again.
Concrete handles pressure better than any other surface we clean, but it still has limits.
- Old, flaking slabsWe lower the pressure so the surface does not crumble.
- Stamped and colored concreteGentler passes protect the color and the old sealer.
- Cracks and jointsRinsed carefully so water does not wash out soil underneath.
- Exposed aggregateCleaned with a lighter touch so stones stay put.
Timing Your Concrete Wash
Wilmington concrete can be cleaned any month, but a few points on the calendar help.
- After pine pollenPollen peaks from late March to early April and coats everything. A wash in mid April gets slabs clean for the warm months.
- Before pool seasonPool decks and patios look best going into summer.
- After stormsHurricane season runs from June to November, and heavy rain splashes mud and leaves on walks and drives.
- Before a sale or a partyFresh concrete frames the house better than anything else at the curb.
Getting Ready for Your Visit
A little prep makes the day go faster, and it takes a few minutes.
- Move the carsClear the driveway and the street side if you can.
- Put away furniture and toysSmall items can hide under the cleaner.
- Turn off sprinklersDry time matters, and spray adds rust on a fresh slab.
- Point out stainsTell us which spots bother you most.
- Leave the water onWe connect to an outdoor spigot unless we bring our own.

Concrete Questions We Hear Often
Will pressure washing leave stripes on my driveway?
Not with a surface cleaner. It spins two jets under a hood, so the whole area gets the same cleaning. Stripes come from wand only cleaning, which we use only on edges.
Why does my concrete turn black?
That black film is usually mildew and algae growing in shade and damp spots. Wilmington humidity makes it common. Cleaning plus a post treatment slows it down.
Can you get rust stains out of concrete?
Most orange rust stains from irrigation water or fertilizer come out with a rust remover, not pressure. Very old stains may lighten instead of disappearing fully.
Hiring a Concrete Crew
If you are comparing options, ask a concrete cleaning company Wilmington NC residents recommend how it avoids stripes and where the washwater goes. When comparing concrete cleaning providers, focus on surface-safe methods, clear pricing and documented results.
Concrete pressure washing Wilmington crews offer varies, so look for a surface cleaner, not just a wand.
