#1 Professional Power Washing & Property Maintenance Company
San Ramon's first Diamond Certified exterior cleaning company. Founded in 2014 with one pressure washer and one vehicle, we now protect hundreds of homes, HOAs, campuses, and commercial properties across San Ramon and the greater East Bay.
We're here to serve you
At Professional Powerwashing & Maintenance, we are more than a power washing company. We are a long-term exterior care partner for homeowners, businesses, HOAs, and property managers throughout San Ramon and the greater East Bay.
Northern California's climate is harder on exteriors than most people realise. Seasonal pollen buildup, morning marine moisture pushing through the Carquinez gap, shaded north-facing slopes that never fully dry, and dry summer dust all drive staining, discoloration, and premature surface wear. Left alone, those conditions do not just change how a property looks. They shorten the working life of your roof, siding, and hardscapes, and that becomes an expensive problem.
That is where our team comes in. We clean and protect residential and commercial exteriors across San Ramon, Danville, Alamo, Walnut Creek, and Dublin, matching the method to the material every time. Our professionalism, technical standards, and attention to detail are what set us apart from anyone with a rented machine.
Regular pressure washing and soft washing saves you money by preventing damage rather than repairing it. We keep your deck, driveway, siding, roof, and every other exterior surface in pristine condition, so replacement stays years away instead of months.

Experience you can trust

We are proud to be a locally owned and operated San Ramon, California company, headquartered at 12893 Alcosta Blvd, Suite G, and open 24 hours. Because we live and work in the same communities we serve, we know exactly which environmental and material challenges local properties face, street by street.
Our technicians are professionally trained, background-checked, and experienced in both residential and commercial exterior cleaning. Every member of our team can identify a surface type on sight, assess the risk factors, and select the correct pressure level, detergent, and application method for that specific project.
We do not take shortcuts, and we do not use one-size-fits-all cleaning methods. Our work standards on every job:
- Surface-specific pressure and soft wash techniques
- Protection of landscaping, paint, windows, and fixtures
- Environmentally responsible cleaning solutions
- Controlled water usage and runoff awareness
- Detailed post-service inspections
This commitment to quality is why property owners across San Ramon continue to trust us year after year.
One pressure washer, one vehicle, no investors
Professional Powerwashing & Maintenance started in 2014 with a single pressure washer, one vehicle, and no team. Brandon Cody Sr. did every job himself: the sales calls, the estimates, the cleanings, the follow-ups. The first year ran out of a garage on a clipboard and handwritten schedules.
The jobs nobody else wanted came first. Moss-covered roofs. Deep-grease driveways. Neglected commercial lots. Those jobs taught the technical craft that still separates us: surface-specific technique for brick, concrete, stucco, vinyl, and asphalt, correct chemical dilution ratios, water pressure calibration, and how to apply surfactants so results actually last.
Before power washing, Brandon worked as a journeyman scaffold builder, where following procedure exactly was the difference between a safe site and a serious accident. That same discipline became the operating standard here.
Between 2014 and 2019 that meant thousands of jobs completed personally across the East Bay, from single-family homes to multi-unit HOAs and Class A retail properties. Every successful project was documented, and those records became the standard operating procedures we train new technicians on today.
By 2020 we were running a crew and two trucks across Danville, Dublin, Walnut Creek, Alamo, Lafayette, and Pleasanton. In 2025 we earned Diamond Certified status, the first exterior cleaning company in San Ramon to do so. In 2026 we launched the HomeGuard Maintenance Membership.

Brandon Cody Sr.
Brandon founded the company in 2014 and spent its first five years in the field, personally completing thousands of jobs across the East Bay. A former journeyman scaffold builder, he brought a procedure-first safety discipline to every service we run. He developed our soft washing approach using biodegradable, non-caustic cleansers, and wrote the SOPs our technicians train on today. He is the author of The Resilient Entrepreneur.

Ray Hirtle
Ray runs day-to-day operations, from crew scheduling and job routing to quality control on every property we service. Customers regularly name him in reviews for coordinating work quickly and following through on the details. He is the reason a job booked on Monday is scoped, staffed, and documented the way it was promised, and he holds the standard on every site our crews touch.

Joshua Martarella
Josh leads our commercial division, working directly with property managers, facility directors, and HOA boards. He spent 20 years in real estate before joining us, buying, selling, and managing multi-family and commercial property, so he understands valuation and what owners actually need from a maintenance partner. He also serves as president of the Lake Forest Volunteer Fire Department, which informs our fire-safe maintenance work.

Felix Aguilar

The craft behind a clean surface
Anyone can rent a machine and point it at a wall. What separates a lasting result from an expensive mistake is knowing what each surface can take, what chemistry the organism responds to, and what the manufacturer warranty allows.
Surface-specific method, not one setting
Brick, concrete, stucco, vinyl, asphalt, cedar, and tile each behave differently under pressure and chemistry. We calibrate water pressure and dilution ratios per surface, and we apply surfactants that extend how long the result holds.
Using one setting for everything is how roofs lose granules and warranties get voided. It is the single most common failure we are called in to fix.
Soft washing as a discipline
Our soft wash approach uses biodegradable, non-caustic cleansers that kill algae, moss, and lichen at the root while protecting the roofing material underneath. It is the method roofing manufacturers actually recommend.
High pressure on a roof knocks the surface layer loose and leaves the organism behind, which is why untreated roofs regrow faster the second time.
Environmental compliance is not optional
We operate under Bay Area environmental regulations for water reclamation and non-toxic chemical use, and follow Best Management Practices for runoff and hazard control on every commercial site.
Plant protection is standard: we pre-wet and shield landscaping, then rinse and neutralise before anything reaches your beds or hardscape.
Documentation on every single job
You get pre and post photo documentation section by section, live updates, digital scheduling, and a client walkthrough before sign-off. Not one wide-angle shot at the end.
That record is what makes our work usable for HOA compliance, insurance submissions, and property sale documentation.
Technical standards on every job
- Chemical dilution ratios calibrated per surface
- Water pressure calibration by material
- Surfactant application to extend results
- TDS-tested water for windows and solar
- Roof access and ladder safety protocols
- Water reclamation and runoff control
- Camera-inspected gutter flushing
- Warranty-safe solar cleaning technique
Diamond Certified, and what that took
Diamond Certified is not a paid badge. An independent research firm calls real customers pulled from company records and surveys them by phone. Companies that score below 90% do not qualify, and most do not pass. We were the first exterior cleaning company in San Ramon to earn it.
Helping homeowners keep their insurance
Across California, homeowners are receiving fire insurance cancellation and non-renewal notices because their properties do not meet updated fire-safe maintenance standards. Insurers are running aerial and ground inspections and flagging what they find.
Roofs with moss, lichen, or organic debris get flagged as fire hazards. Gutters packed with dry leaves and pine needles are identified as ignition points. Properties with no documented maintenance history face premium increases or outright cancellation.
This is an area we understand from both sides. Our Director of Sales, Josh Martarella, serves as president of the Lake Forest Volunteer Fire Department in Lassen County and was evacuated from his own cabin twice during wildfire seasons. He joined that board after the Hog Fire in 2020.
We provide the exterior cleaning and, critically, the documentation insurance brokers can actually submit to carriers: timestamped before-and-after photography, inspection reports, and maintenance logs.
- Roof soft washing to remove moss, lichen, and organic debris flagged by inspectors
- Gutter cleaning and guard installation to eliminate dry debris ignition points
- Full exterior cleaning to meet fire-safe property maintenance standards
- Before-and-after photo documentation formatted for broker submission
- Inspection reports and maintenance logs for insurance restoration cases
What we provide
- Free roof and gutter inspection
- Timestamped photo documentation
- Written inspection report
- Maintenance log for your carrier
- Reports sent direct to your broker

And work was done in a fast and efficient mannerPosted on Google Kunjal VaitharaTrustindex verifies that the original source of the review is Google. 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 Eva DeagenTrustindex verifies that the original source of the review is Google. On time. Friendly people.
