About this service

What Patio Cleaning Pasadena CA Actually Involves

Patio Cleaning Pasadena CA is the process of removing organic growth, mineral deposits and embedded soil from outdoor hardscapes and wood surfaces using a mix of soft washing, pressure washing and hand detailing. We start by identifying the surface: broom-finished concrete, exposed aggregate, clay pavers, travertine, flagstone or a wood deck. Each one takes a different pressure setting and a different cleaning solution. A pressure washer alone will etch soft stone and strip sealer, so we match the tool to the material before a single drop hits your patio.

Pasadena patios take a beating. Morning marine layer moisture feeds black algae on north-facing concrete, and our dry summers bake sprinkler overspray into hard water stains that won't scrub out. Add jacaranda and oak debris, and a patio can look ten years older in two seasons. Homeowners near Arroyo Terrace and Bungalow Heaven call us most in spring and fall, but patio cleaning in Pasadena CA near me searches spike year-round after windstorms. If you're hosting, book two weeks out.

What's included

What's Included in Patio Cleaning Pasadena CA

Every patio cleaning includes pretreating, surface cleaning, edge detailing and a final rinse. Add-ons like sealing, screen repair or gutter cleaning can be bundled on the same visit. Here's what you can count on.

01
✓

Organic Growth Treatment

We apply a soft wash solution to black algae, mold, moss and mildew across concrete, pavers and wood. The solution dwells 5 to 10 minutes to kill growth at the root, then rinses clean. This is included on every job, not sold as an upgrade.

02
✓

Hard Water and Rust Pretreat

Sprinkler overspray, rust drip marks and fertilizer stains get a dedicated hard water remover before pressure washing. We let it dwell, agitate with a brush where needed, and rinse. Most mineral staining lifts in one treatment.

03
✓

Surface-Specific Cleaning

Concrete and asphalt get the pressure washer at 1,200 to 2,500 PSI. Travertine, flagstone, clay pavers and wood get soft washing or hand scrubbing with microfiber towels. We match the method to the material so nothing gets etched.

04
✓

Edge and Corner Detailing

Wands can't reach the corners where patios meet walls, planters or steps. We hand scrub those areas with brushes and scrapers, then rinse. This is the detail that makes a patio look finished rather than just hosed off.

05
✓

Furniture and Glass Wipe-Down

Patio furniture frames, glass doors, mirrors and light fixtures get wiped down during the final pass. We use Invisible Glass and microfiber cloths on glass, and we clear window tracks and sills of patio dust.

06
✓

Full Rinse and Walkthrough

We rinse the entire surface, direct runoff away from planters and drains, and walk the patio with you before leaving. You'll get drying times and maintenance notes, plus a 1-year workmanship warranty on the cleaning.

How it works

Our Patio Cleaning Process, Step by Step

We walk the patio with you, note the surface type, square footage, drainage and any problem areas like rust or oil. You get a flat price before we start, not an hourly estimate. Most quotes take 15 minutes on site or over the phone with a few photos.

We cover nearby plants, outlets and furniture, then apply a soft wash solution to organic growth and a hard water remover to mineral stains. The solution dwells 5 to 10 minutes so it does the work instead of brute pressure. This is the step that separates a real clean from a rinse.

Concrete and pavers get the pressure washer at a controlled setting, usually 1,200 to 2,500 PSI depending on hardness. Wood and softer stone get hand scrubbing with microfiber towels and a soft wash system. Edges, corners and steps are detailed by hand because a wand can't reach them.

We clean patio furniture frames, wipe down glass doors and mirrors, clear window tracks and sills that collect patio dust, and rinse away all runoff. If your screens are dusty or torn, we can handle screen cleaning or screen repair on the same visit.

We rinse the entire area, check for missed spots and walk it with you before packing up. You'll get a short rundown on drying time, typically 4 to 6 hours, and any maintenance notes. Payment is due on completion, and we warranty our workmanship.

Tools & methods

Tools and Methods We Use on Pasadena Patios

01
✓

Pressure Washer

Used on concrete, asphalt and durable pavers at 1,200 to 2,500 PSI. We swap nozzles and adjust pressure based on surface hardness, and we test a small area before committing.

02
✓

Soft Wash System

Delivers cleaning solution at low pressure for travertine, flagstone, wood and painted surfaces. This is what kills algae at the root without etching delicate stone.

03
✓

Ettore and Unger Squeegees

Used on glass doors, mirrors and patio-facing windows. These brands hold a clean edge longer, which means fewer streaks and less rework.

04
✓

Pulex Scraper

Removes paint overspray, sticker residue and hardened mineral deposits from glass and hard surfaces without scratching when used correctly.

05
✓

Microfiber Towels and Cloths

For hand scrubbing wood, wiping furniture frames, detailing sills and tracks, and final glass passes. We use fresh towels per surface to avoid cross-contamination.

06
✓

Gutter Scoop

Clears roof debris and patio runoff from gutters so overflow doesn't stain the patio below. We check downspout flow on every bundled visit.

Real results

Before and after.

Bungalow Heaven Concrete Patio Rescue
Patio Cleaning

Bungalow Heaven Concrete Patio Rescue

A 400-square-foot concrete patio under two mature oaks hadn't been cleaned in four years. Black algae covered the shaded half, and leaf tannins had stained the rest a mottled brown. The homeowner had tried a garden hose and a stiff brush with no result.

After: We soft washed the algae, pretreated the tannin stains, then pressure washed at 1,800 PSI. The slab came back to a uniform gray, and the algae smell was gone. Total job time was three hours, and the homeowner booked a fall follow-up.

Hastings Ranch Pool Deck and Pavers
Patio Cleaning

Hastings Ranch Pool Deck and Pavers

A 700-square-foot paver pool deck had hard water rings around the spa and slick algae along the shaded edge. The homeowner was worried pressure washing would blow out the joint sand and loosen the pavers.

After: We soft washed the pavers at low pressure, treated the mineral rings with a hard water remover, and re-sanded the joints. The deck dried even in color with no loose pavers. The job took four hours including the re-sand.

South Lake Avenue Commercial Courtyard

A mixed-use building's 500-square-foot courtyard patio had years of gum spots, algae in the shaded corners and streaked glass doors. Tenants had complained about the appearance for months.

After: We pressure washed the concrete, hand scrubbed the corners, and cleaned the glass doors and mirrors on the same visit. The courtyard was ready for use the next morning. The property manager moved us to a quarterly schedule.

Problems we solve

Patio Problems We Solve for Pasadena Homeowners

Most patios we see have two or three issues stacked on top of each other. Here's what we run into and how we fix it.

Ask a pro →
01

Black algae slick on shaded concrete and pavers

We apply a soft wash solution that kills the growth at the root, let it dwell, then rinse at controlled pressure. For heavy buildup, we agitate with a brush first. Most patios come back to a uniform color in one visit, and we can add a paver sealer to slow regrowth.

↗
02

Hard water stains from sprinklers and drip lines

We pretreat with a hard water remover, let it dwell, then rinse. For stubborn rings we agitate with a Pulex scraper or brush. Most staining lifts in one treatment, and we can seal afterward to make future cleaning easier.

↗
03

Dirt tracked from patio into the house

We clean the patio surface, then clear window tracks and sills as part of the detail pass. We also wipe glass doors on both sides. Customers tell us the house stays cleaner for weeks after a patio cleaning.

↗
04

Faded, gray wood decks attached to patios

We hand scrub wood with a soft wash solution rather than pressure washing, which avoids splintering. Once dry, we can apply a deck sealer to lock in the color. Most decks brighten two to three shades after one cleaning.

What Pasadena Customers Say

★★★★★
“Our back patio had black algae so thick you could see footprints in it. The crew soft washed the whole thing and hand scrubbed the edges near the planter beds. Two hours in, it looked like a different slab. They also cleaned the sliding door glass and the window tracks without me asking. Fair price, showed up on time, no upsell.”

“I manage a small commercial building with a courtyard patio. Rose City cleans it quarterly along with the windows and gutters. They work around our tenants, keep the runoff out of the planters, and invoice exactly what they quoted. Six years in business and it shows in how they handle a schedule.”

Frequently Asked Questions About Patio Cleaning

877-318-1882 →

Most residential patios in Pasadena run $180 to $450 in 2026, depending on square footage, surface type and how much organic growth has built up. A small 200-square-foot concrete patio starts around $180. A 600-square-foot paver patio with heavy algae and hard water staining can reach $450 or more. We quote flat rates after a quick walkthrough or a few photos.

Yes. Black algae and mold on concrete, pavers and wood are the most common thing we treat. We apply a soft wash solution that kills the growth at the root, let it dwell, then rinse. Surface mold usually clears in one visit. If it has been growing for years in a shaded area, we may recommend a follow-up treatment 30 days later.

Once a year is the baseline for most Pasadena patios, and twice a year if yours sits under trees or stays shaded. North-facing patios near the arroyo collect algae faster because they stay damp longer. If you have a pool deck or entertain often, plan on spring and fall cleanings. Sealed pavers and decks hold up better between visits.

No, and that's why we don't use it on everything. Concrete and asphalt handle pressure well, usually 1,200 to 2,500 PSI. Travertine, flagstone, soft clay pavers and wood can be etched or splintered by a pressure washer, so those get soft washed or hand scrubbed with microfiber towels instead. We test a small area first and adjust before doing the full surface.
