HOA Common Area Cleaning in San Lorenzo, CA
Associations across San Lorenzo, from the streets off Hesperian Boulevard to the properties near Lewelling Boulevard and Via Mercado. Walkways, breezeways, building exteriors and shared hardscape, scheduled around residents and documented for the board.
The supply your sprinklers run on
San Lorenzo is unincorporated Alameda County rather than an incorporated city, and it sits in EBMUD service territory. EBMUD hardness across its plants runs well below the threshold that produces visible mineral deposits, so irrigation scale is not what marks a San Lorenzo property. The jurisdiction point matters more: work here falls under Alameda County rather than a city public works department, which affects who you are dealing with on stormwater and permits.

A uniform housing stock with uniform problems
San Lorenzo is unusual in how consistent its housing stock is. Much of the community was developed as a planned post-war subdivision, which means a large share of the building fabric is the same age and built the same way. For an association that is genuinely useful: the problems are predictable, they appear on the same elements across the whole property, and a condition found on one building is almost certainly present on the rest.
It also means deferred maintenance compounds uniformly. When original materials reach the end of their service life they do it everywhere at once rather than building by building, so a board here benefits more than most from documented condition tracking over time.
What we clean on a San Lorenzo association property
Mail kiosks and utility enclosures
Scoped explicitly, because these are the shared elements most often left off a quote.
Connecting paths between buildings
Short runs that add up, and usually the surfaces skipped for several cycles.
Walkways, breezeways and stair treads
The surfaces residents use every day, treated as a safety item rather than an appearance one.
Building exteriors
Stucco, siding and trim soft washed at a pressure the substrate tolerates, never blasted.
Shared hardscape
Drive aisles, guest parking, entry aprons, pool surrounds and patio areas.
Gutters and downspouts
Cleared as part of the work, so the stain on the wall below does not simply return.
Mature street trees and what they drop
The tree canopy across much of San Lorenzo is as old as the housing, and mature trees over a flat site deposit steadily onto roofs, into gutters and onto every walkway beneath them. On a flat property that debris does not wash away in winter, it sits. Wet leaf litter left on concrete leaches tannin into the surface and leaves a brown stain that is routinely mistaken for rust and treated with the wrong chemistry.

County jurisdiction, not city
Because San Lorenzo is unincorporated, stormwater and discharge questions go through Alameda County rather than a city department. In practice the requirements are the same ones we work to everywhere: wash water controlled and kept out of the storm drain system, captured where it contains anything beyond soil, and the work documented. It is worth a board knowing which agency has jurisdiction before a complaint arrives rather than after.
Mail kiosks, utility areas and the shared bits in between
On a San Lorenzo property the shared elements that fall between obvious categories are the ones that get missed: the mail kiosk surround, the utility and meter enclosures, the bin storage area, the bench and seating pads, and the short connecting paths between buildings. Individually none is large. Together they are a meaningful share of what residents actually look at and stand on.
They also tend to be the parts that have been skipped for several cycles, so they come up slower and need more work the first time than the main walkways do. We scope them explicitly so the board can see them on the quote rather than discovering they were excluded after the crew has gone.
From walkthrough to documented close-out
Survey the site
Including grade, access, stair runs and where water will go, because those three things set the method and the price.
Agree the window
Hours and sequence set with the board, notice posted ahead of the date, equipment positioned away from shared property lines.
Clean in the right order
Top down, shaded elevations given the dwell time they need, walking surfaces finished so they drain and dry.
Leave a record
Before and after photographs for every area, plus the certificate of insurance already on file with your manager.

I couldn’t be happier with the service from Professional Power Wash and Management (PPWPM)! This job was done at my home in Walnut Creek, and the team did an absolutely fantastic job with both the power washing and the windows—everything looks spotless and refreshed. The windows are super clean I have a property with a front yard, backyard, and side yard—quite an area to be cleaned—along with a mix of surfaces including bricks, concrete, and even a tennis court. They handled every single detail with care and precision. It’s not easy to manage such variety, but they truly did an outstanding job across the board. A special shoutout to Ray, who I was in touch with throughout the process. He is truly wonderful—extremely patient, professional, and has outstanding customer service. What I really appreciated is that he genuinely understands what a customer wants. I’m someone who is very particular (a bit of a clean freak!), and when I pointed out certain things, he made sure everything was taken care of without hesitation. That level of attention and responsiveness really stands out. Honestly, when a business truly takes care of its customers, you know they’re going to do well—and that’s exactly the feeling I got here. Communication was seamless—every text message was responded to promptly, with no delays or confusion. The team was very punctual and arrived right on time. Everything was smooth and efficient from start to finish. They also offer a wide range of services, and based on this experience, I’ll definitely be using them again in the future. It was such a pleasant experience overall. You come across very few companies whose service is truly 10 on 10—and this is definitely one of them. I highly recommend PPWPM to everyone in Walnut Creek and beyond who is looking for power washing or any of the services they offer. I’m 101% sure they’ll do a great job. If you love a fresh-looking home, you will be absolutely happy and thrilled!Posted on Google![]()

HOA cleaning in San Lorenzo, answered
Is San Lorenzo covered by city or county rules?+
County. San Lorenzo is unincorporated Alameda County rather than an incorporated city, so stormwater and discharge questions go through the county rather than a city public works department. The practical requirements are the same either way: wash water controlled, kept out of the storm drain system, captured where it carries more than soil, and the work documented.
Why does the same problem appear on every building in our association?+
Because much of San Lorenzo was developed as a planned post-war subdivision, so a large share of the building fabric is the same age and construction. Conditions appear uniformly rather than building by building. That makes problems predictable, and it also means original materials tend to reach the end of their service life everywhere at once.
What causes the brown staining under our trees?+
Tannin from wet leaf litter sitting on concrete. On a flat San Lorenzo site that debris does not wash away over winter, it sits and leaches into the surface. The stain is routinely mistaken for rust and treated with an acidic product, which does nothing. Tannin needs alkaline chemistry, the opposite approach.
Do we have a hard water problem here?+
No. San Lorenzo is in EBMUD territory, where published hardness runs well below the level that leaves visible mineral deposits. Irrigation scale is not what marks these properties, so descaling is not something you should be paying for.
Are you licensed and insured for association work?+
Yes. CSLB #1022456 with C61/D38 classifications, bonded, with general liability and workers compensation. A certificate naming the association and the management company as additional insured is issued before the service date.
