About this service
What Concrete and Asphalt Cleaning Pasadena CA actually involves
Concrete and Asphalt Cleaning Pasadena CA is the process of removing embedded dirt, oil, rust, mold, and tire marks from hardscape surfaces using pressure, heat, and surface-specific chemistry. We start by identifying the substrate, because a 4,000 PSI turbo nozzle that strips a driveway can etch a soft asphalt parking lot in seconds. From there we match the method: hot-water pressure washing for concrete, lower-pressure soft washing with a Zep or Simple Green degreaser for asphalt, and post-treatment to stop mold from returning. The goal is a uniform finish, not a zebra-striped pad.
Pasadena hardscape takes a specific beating. Santa Ana winds drop grit and pollen across the 91101 and 91103 ZIPs, summer UV bakes oil stains into concrete, and winter rain turns that same grit into a slippery film on walkways. If you have been searching for a concrete cleaner near me Pasadena, the tell is usually a driveway that looks clean when dry and turns black the moment it gets wet. That dark shadow is embedded hydrocarbon, and it needs heat and dwell time, not a garden hose.

What's included
What our Concrete and Asphalt Cleaning Pasadena CA includes
Every job includes a walkthrough, surface testing, pre-treatment of stains, pressure or soft washing, edge detailing, and a final rinse. Add-ons like paver sealing, gutter cleaning, and window cleaning can be bundled on the same visit. Here is the core scope.
Oil and rust pre-treatment
Stains get a dedicated degreaser applied with a pump sprayer, agitated with a stiff brush, and left to dwell 10 to 20 minutes. This is what lifts hydrocarbon out of the pore instead of smearing it around.
Pressure or soft washing
Concrete gets 3,000 to 4,000 PSI through a rotating surface cleaner. Asphalt gets 1,200 to 1,500 PSI with a wide fan tip and soft wash solution. We overlap passes to avoid stripes and keep runoff contained.
Edge and joint detailing
Garage aprons, expansion joints, fence lines, and borders get hand work with a wand and a scraper. This is the 20 to 30 minutes that separates a uniform clean from a patchy one.
Final rinse and walkthrough
We rinse the full surface, then walk it with you in daylight. You hear what will not come out, what we found under the dirt, and how long to stay off the surface. Most driveways are dry in 2 to 4 hours.
How it works
How our concrete and asphalt cleaning process runs
We walk the surface with you, note oil, rust, paint, and cracks, then test a small hidden patch with water and degreaser. That test tells us the correct PSI and chemistry before we touch the main area. Takes 10 to 15 minutes.
Oil, rust, and organic stains get a targeted pre-treatment. We apply degreaser with a pump sprayer, agitate with a stiff brush, and let it dwell 10 to 20 minutes. This is the step that separates a real clean from a rinse.
Concrete gets a rotating surface cleaner at 3,000 to 4,000 PSI. Asphalt gets a lower-pressure soft wash with a wide fan tip. We work in overlapping passes so there are no stripes, and we keep runoff away from storm drains.
Edges, expansion joints, garage aprons, and fence lines get hand work with a wand and a scraper. This is where cheap jobs show. We spend the extra 20 to 30 minutes so the border matches the field.
Final rinse, then a walkthrough with you in daylight. We point out anything that will not come out, anything we found under the dirt, and how long to stay off the surface. Most driveways are dry and ready in 2 to 4 hours.

Tools & methods
Tools and methods we use on Pasadena hardscape
Truck-mounted pressure washer
Delivers 3,000 to 4,000 PSI for concrete flatwork with consistent heat and flow, so large driveways and lots finish in one pass.
Rotating surface cleaner
Spins two high-pressure jets under a shroud to clean flat concrete evenly, eliminating the zebra stripes a single wand leaves behind.
Soft wash system
Applies cleaning solution at low pressure for asphalt, painted surfaces, and delicate pavers, so the binder is never gouged.
Pump sprayer and stiff brush
Puts degreaser exactly where the oil is and works it into the pore before the pressure hits, which is what lifts old stains.
Zep and Simple Green degreasers
Surface-safe chemistry that breaks down hydrocarbon and organic film without leaving a residue that attracts new dirt.
Scraper and hand wand
Details expansion joints, garage aprons, and fence lines where a surface cleaner cannot reach, so the borders match the field.
Real results
Before and after.
Concrete and Asphalt Cleaning
Two-car driveway, ten years of oil
A 500-square-foot Pasadena driveway with overlapping oil drips from two cars and a motorcycle. The center was black when wet, and the expansion joints were packed with grit and weeds.
After: After pre-treatment and a 4,000 PSI surface clean, roughly 85 percent of the oil lifted. The slab dried uniform gray, and the joints were hand-detailed. The homeowner said it looked like new concrete.

Concrete and Asphalt Cleaning
Retail parking lot, 6,000 square feet
A South Lake Avenue District lot with black tire scuffs, gum spots, and a green mold film along the shaded north edge. Tenants had complained for months.
After: We soft washed at 1,200 PSI, scraped gum, and treated the mold. The lot dried even, with no gouges or stripes. The property manager scheduled a twice-yearly clean.

Concrete and Asphalt Cleaning
Back patio, mold and barbecue grease
A shaded Victory Park patio with black mold in the grout lines and a grease ring under the grill. The surface was slick after every rain.
After: We soft washed the pavers, treated the mold, and degreased the grill area. The patio dried evenly, and the traction improved immediately. The homeowner booked window cleaning for the same visit.

Problems our concrete and asphalt cleaning solves
Hardscape fails in predictable ways in Pasadena. Here are the four calls we get most, and what we do about each one.
Ask a pro →Black oil shadow that returns when wet
We apply a Zep or Simple Green degreaser, agitate, and dwell it 10 to 20 minutes, then run 200-degree water through a rotating surface cleaner. On a 400-square-foot driveway, that pulls 80 to 90 percent of the visible stain in one visit.
Green and black mold on shaded concrete
We soft wash the affected area with a cleaning solution, let it dwell, then rinse at low pressure. The biological layer lifts without etching the slab, and we treat the edges so it does not creep back from the fence line.
Rust rings from sprinklers and patio furniture
We use a dedicated rust remover matched to the surface, apply it in small sections, and rinse before it dries. Most rings lift in one treatment. We also point out the sprinkler head causing it so you can fix the source.
Tire marks and gum on commercial asphalt
We pre-treat with degreaser, then soft wash the asphalt at 1,200 to 1,500 PSI. Gum gets a scraper and a targeted solvent. We schedule early morning or Sunday so the lot is dry and open before your first customer arrives.
Transparent pricing
What Concrete and Asphalt Cleaning Pasadena CA costs
$180 - $450 for most residential driveways; $0.10 - $0.25 per square foot for commercial lots
Typical 2026 pricing in Pasadena runs $180 to $450 for a residential driveway, and $0.10 to $0.25 per square foot for commercial lots. The variables are square footage, stain severity, surface type, and access. A light 300-square-foot patio sits near the low end. A two-car driveway with heavy oil and a slope sits near the high end. We quote after a walkthrough, and the price does not change unless you add scope. If you want affordable concrete and asphalt cleaning Pasadena CA, the honest answer is that the cheapest bid often skips the pre-treatment that actually removes the stain.
You are paying for pre-treatment, matched pressure, and edge detailing, not just water. That is what makes the clean last a year instead of a week, and it is why we quote the job honestly before we start.

Price scales with area. A 300-square-foot patio is a different job than a 6,000-square-foot lot. We measure on site and quote per square foot for larger surfaces.

Light dirt is a single pass. Heavy oil, rust, or paint requires pre-treatment, dwell time, and sometimes a second application, which adds labor and chemistry.

Concrete tolerates high pressure and cleans fast. Asphalt needs soft washing at low pressure, which takes longer and requires more care around the binder.

Customer reviews
What Pasadena customers say
★★★★★
“Our driveway had ten years of oil drips from two cars and a motorcycle. Rose City pre-treated everything, let it sit, then ran the surface cleaner. I would say 85 percent of the stains are gone, and the rest are faint. They also cleaned the expansion joints by hand, which the last company skipped. Worth every dollar.”

“We manage a small retail strip with a shared parking lot. They cleaned 6,000 square feet of asphalt on a Sunday morning before tenants opened. No gouges, no stripes, and they kept runoff out of the storm drain. We now schedule them twice a year.”

“I called about concrete cleaning near Victory Park for my mother's house. They walked the property with her, explained what would and would not come out, and gave a written price on the spot. The patio and walkway look new, and they cleaned the window sills while they were there.”

✓ VerifiedMost residential driveways in Pasadena run $180 to $450 in 2026, depending on square footage, stain severity, and access. A standard 400-square-foot driveway with light dirt lands near $200. Heavy oil, rust, or a two-car width with a slope pushes it toward $400. Commercial lots are quoted per square foot, usually $0.10 to $0.25.
Yes, and we remove most of them. Fresh oil lifts almost completely with degreaser and 200-degree water. Oil older than a year has polymerized into the pores, so expect 70 to 90 percent removal on a first visit. We pre-treat, dwell, and agitate. If a stain is truly permanent, we tell you at the walkthrough before you commit.
Not at concrete pressure. Asphalt is a softer binder, so we drop to 1,200 to 1,500 PSI with a wide fan tip and a soft wash approach. That removes dirt, mold, and tire film without gouging the surface. We also avoid hot days above 90 degrees, when softened asphalt can scar under a wand.
Most Pasadena homes do well on an annual clean, ideally in late spring after the pollen drops and before summer UV bakes stains in. Commercial walkways and parking lots with heavy traffic should be cleaned two to four times a year. If your driveway turns dark when wet, that is your signal, not the calendar.
