About this service
Pressure Washing Pasadena CA: What the Work Actually Involves
Pressure Washing Pasadena CA is exterior surface cleaning that uses heated water and controlled pressure to lift dirt, algae, oil, and mineral buildup off hard surfaces. We run 3,000 to 4,000 PSI through a rotating surface cleaner for flatwork, then switch to a 25-degree tip for edges, expansion joints, and brick. Water temperature sits between 180 and 200 degrees, which breaks down grease that cold water just pushes around. Most driveways take 90 minutes to three hours depending on square footage and how long the buildup has been sitting.
Pasadena properties deal with two stubborn problems: black algae that feeds on morning marine layer moisture, and hard water stains left behind by sprinkler overspray. We see both constantly in Bungalow Heaven, Madison Heights, and along the South Lake Avenue District. If you have been hunting for pressure washing in Pasadena CA near me, that combination of humidity and mineral-heavy water is exactly why a once-a-year rinse is not enough for most driveways.

What's included
What Our Pressure Washing Service Includes
Every pressure washing job includes surface matching, pre-treatment, flatwork cleaning, edge detailing, and a full rinse. Add-ons like paver sealing, gutter cleaning, and screen repair can be bundled into the same visit.
Pre-Treatment and Soft Wash
A soft wash solution goes down on algae, mold, and organic growth and sits 10 to 15 minutes. That soak time lets chemistry lift the growth so pressure does not have to.
Flatwork and Edge Cleaning
Driveways, patios, and walkways get full surface cleaner coverage, then a hand wand for expansion joints, steps, and the edges where dirt always collects.
Sill, Track, and Screen Rinse
Splash from pressure washing lands on window sills and tracks. We wipe them with a microfiber cloth, rinse screens, and clear the debris so nothing dries into a streak.
Drain and Runoff Clearing
We flush drains and check that runoff flows away from the foundation, not toward the garage. Any debris we pull out gets bagged and hauled off site.
How it works
How Our Pressure Washing Process Runs
We walk the property with you, measure square footage, and check surface types, drainage, and any cracks or loose pavers. You get a flat number before we start, not an hourly estimate. This takes about 15 minutes and costs nothing.
We pre-soak landscaping, tape off door thresholds, and cover outlets. A soft wash solution goes down on organic growth and sits for 10 to 15 minutes so the pressure does less of the work. That soak time is what keeps concrete from getting etched.
A rotating surface cleaner covers the flatwork in overlapping passes at 3,000 to 4,000 PSI. Edges, steps, and tight corners get a hand wand with a 25-degree tip. We keep the wand moving and never hold it in one spot, which is how streaks and etch marks happen.
Expansion joints, fence lines, and the base of stucco walls collect the dirt that flatwork cleaning misses. We flush those areas, rinse window sills and door tracks, and clear debris from drains so nothing washes toward your garage.
We do a full rinse, then walk the job with you before packing up. If a spot needs another pass, we do it on the spot. You get a written summary of what was cleaned and a recommendation on how often to repeat it.

Tools & methods
Equipment and Methods We Use
Rotating Surface Cleaner
Covers flatwork in overlapping passes at 3,000 to 4,000 PSI with no streaks. It is the reason driveways come out even instead of striped.
Heated Pressure Washer
Runs water at 180 to 200 degrees to break down oil, grease, and organic growth that cold water cannot lift from concrete pores.
Soft Wash System
Applies cleaning solution at low pressure for stucco, siding, wood decks, and awnings where a pressure wand would cause damage.
25-Degree Wand Tip
Handles edges, expansion joints, steps, and tight corners that the surface cleaner cannot reach without splashing walls.
Water-Fed Pole
Reaches second-story windows and solar panels with purified water so we clean glass without a pressure wand near seals.
Squeegee and Microfiber Cloth
Used on window sills, tracks, and glass after washing so splash marks do not dry into streaks.
Real results
Before and after.
Pressure Washing
Bungalow Heaven Driveway Algae Removal
A 1940s concrete driveway with black algae running the full length and dark tire marks near the garage. The homeowner had tried a garden hose and a stiff brush with no result. Shaded by two mature oaks, the slab stayed damp most mornings.
After: After pre-treatment and a 1,500 PSI surface cleaner pass, the concrete returned to light gray with no etching. Tire marks lifted with heated water and degreaser. Total job time was two hours and 15 minutes.

Pressure Washing
San Rafael Sprinkler Stain Cleanup
Sprinkler heads had been hitting the driveway and walkway for years, leaving white mineral rings and cloudy glass on the front windows. The driveway looked chalky and the glass resisted normal cleaning.
After: We removed the hard water stains from glass with a dedicated remover and ran repeat passes on the concrete. The driveway came back to a uniform color, and the front windows read clear from the street. Job took three hours.

Pressure Washing
Playhouse Village Commercial Walkway
A commercial entry walkway with gum spots, algae in the shaded corners, and grime tracked in from the street. Tenants had complained, and the frontage looked neglected compared to neighboring buildings.
After: We cleaned the walkway at matched pressure to protect the finish, removed gum with heated water, and cleaned the glass doors the same morning. The entry was finished before 8 a.m. and the property went on a twice-a-year schedule.

Problems Pasadena Pressure Washing Solves
Concrete problems in Pasadena rarely fix themselves. These are the ones we get called about most, and what happens if they sit.
Ask a pro →Black algae streaks spreading across the driveway
We pre-treat with a soft wash solution, let it soak, then run a surface cleaner at matched pressure to remove the growth layer. Most driveways come back to their original color in a single visit.
Oil drips and tire marks that will not rinse off
We use heated water at 180 to 200 degrees plus a degreaser on the affected area. The heat breaks the oil bond so the surface cleaner can lift it instead of pushing it deeper.
Hard water stains from sprinkler overspray
We treat glass with a dedicated hard water remover and use repeat passes on concrete to break the mineral bond. Adjusting sprinkler heads to stop hitting the slab prevents it from coming back.
Moss and slick growth on shaded walkways
We clean walkways at reduced pressure so mortar joints stay tight, then flush the growth out of the joints. A follow-up rinse each spring keeps it from returning.
Transparent pricing
Pressure Washing Pricing in Pasadena
$180 - $850 depending on scope
Typical 2026 pricing in Pasadena runs $180 to $450 for a standard residential driveway, and $400 to $850 when you combine a driveway with a patio or long walkway. Walkway-only jobs often land under $200. Square footage is the biggest driver, followed by staining severity and surface type. Older concrete that needs lower pressure and more pre-treatment takes longer, which affects the number. We quote flat rates before we start, so the price you hear is the price you pay. If you want pressure cleaning Pasadena California done right the first time, the quote visit is free.
You are paying for surface matching, pre-treatment, and a crew that rinses sills and clears drains before leaving. That is what keeps concrete intact and results looking finished instead of half-done.

Customer reviews
What Pasadena Customers Say
★★★★★
“Our driveway had black algae streaks running the full length and I figured it was permanent. The crew pre-treated it, ran a surface cleaner over the whole slab, and it came back to light gray. They also rinsed the window sills and cleared the drain at the bottom of the driveway without being asked. Took about two hours.”

★★★★★
“We had sprinkler stains and tire marks on the driveway plus a mossy back patio. They matched the pressure to the older concrete instead of blasting it, which I appreciated. The patio pavers came out clean and the sand in the joints stayed put. Booked them again for the walkways three months later.”

“We manage a small commercial building and the entry walkway was a mess with gum and algae. Rose City cleaned it at matched pressure so the concrete finish stayed intact, then cleaned the glass doors the same morning. Tenants noticed. We now have them on a twice-a-year schedule.”

Dennis R.Property Manager, South Lake Avenue District
✓ VerifiedMost residential jobs run $180 to $450 in 2026, with larger driveways and combined driveway-plus-patio packages landing between $400 and $850. Square footage drives the number more than anything else, followed by how heavy the algae or oil staining is. Walkway-only jobs often come in under $200. You get a flat quote before we start.
Concrete driveways, walkways, patios, asphalt, brick, pavers, and retaining walls all take pressure washing well when the PSI is matched to the material. Wood decks and painted surfaces need lower pressure and a soft wash solution. We do not pressure wash stucco or siding directly. Window screens, sills, and tracks get cleaned by hand with a microfiber cloth and squeegee.
Once a year is the baseline for most Pasadena driveways, and every 18 months is fine for walkways that get partial shade. Properties near the Arroyo or under heavy tree cover usually need it twice a year because algae regrows faster in damp, shaded conditions. If you can see dark streaks spreading, you are already past due.
Yes, if someone uses too much pressure or holds the wand in one spot. Etching, streaks, and loosened aggregate are all operator errors, not concrete problems. We cap flatwork at 4,000 PSI with a rotating surface cleaner and drop to 1,200 to 1,500 PSI on older or already-cracked slabs. We also pre-treat and pre-soak, which lets chemistry do the work instead of raw force.
