The basics
General questions
What is the difference between power washing and pressure washing?
Both use high-pressure water. Power washing adds heat. Hot water is what breaks down oil, grease and gum on commercial concrete, so most of our commercial work is power washing with hot water units and flat surface cleaners.
How much does commercial power washing cost in Los Angeles?
Commercial work is priced by square footage, the type and age of the staining, access, and whether wash water has to be recovered. Recurring routes cost less per visit than one-time restoration cleans. We give a written price after walking the site or seeing photos, and we will clean a test patch free so you can judge the result first.
Do you work at night?
Yes. Most of our commercial work is done after closing or before opening so parking, pumps and entries stay available during business hours. We are open every day from 7 AM to 11:30 PM, and later by arrangement.
Which areas do you serve?
Los Angeles County, Orange County, the Inland Empire (San Bernardino and Riverside counties) and Ventura County. Our shop is in Chino, where those regions meet. We also travel further for multi-site operators and scheduled station work.
Are you licensed and insured?
Yes. Pressurize Washing Systems LLC holds California contractor license CSLB #1152154 and is insured. We send a certificate of insurance to your property manager or brand on request.
What happens to the dirty wash water?
It stays out of the storm drain. California stormwater rules prohibit wash water carrying oil, detergent or debris from entering storm drains, and the property owner can be cited as well as the contractor. We block drains, collect the water and dispose of it properly, and we bring full reclaim equipment when a site needs zero discharge.
What is the free on-site demo?
Before you commit, we come out and wash a test patch on your worst concrete. You see exactly what our hot water equipment does on your surface, and we see what the job needs. It costs nothing and there is no obligation.
Do you only do commercial work?
Commercial and industrial properties are our focus: gas stations, parking lots and structures, shopping centers, restaurants, warehouses, fleets and multi-unit communities. Our equipment, hours, insurance and water recovery are all set up for that kind of work.
How often should a commercial property be pressure washed?
It depends on traffic. Gas stations and drive-thrus often need service every one to six weeks. Storefront sidewalks are commonly monthly. Parking lots, structures and building exteriors are usually cleaned quarterly to once a year.
Can you remove old oil stains from concrete?
Usually, and always a great deal lighter. We pre-treat with degreaser and wash with hot water. Stains that have bonded with the concrete over years can be taken off with sandblasting. The free demo shows you what to expect before you spend anything.
Do you offer maintenance contracts?
Yes. Weekly, monthly and quarterly routes are available with a fixed scope and price per visit, photo reports, and one point of contact for multi-site portfolios.
How quickly can you start?
Quotes usually go out the same day. Graffiti and spills are often handled within 24 hours. Larger projects are scheduled around your operations, typically within a week or two.
Will pressure washing damage my concrete, paint or striping?
Not when it is done correctly. We match pressure, heat and detergent to each surface, lower the pressure over striping and painted finishes, and soft wash stucco, wood and signage.
Do you respond to emergencies?
Yes. We offer 24-hour response for oil, fuel and grease spills on pavement. Call (714) 867-3418 and you will get an arrival time on the phone.
Gas Station Cleaning questions
What areas do you provide gas station washing in?
We clean gas stations and other commercial properties across Ventura County, Los Angeles County, Orange County, Riverside County and San Bernardino County, and we have completed station work in San Diego as well.
Why should I choose Pressurize Washing Systems for my gas station?
Gas stations are the biggest part of what we do. With over five years of experience, a 5.0 Google rating across more than 100 reviews, and repeat work for Chevron, 76 and Sinclair operators, we know how to deep clean a station without shutting it down.
What does the gas station washing service include?
Pumps and dispensers, fueling pads, sidewalks, parking stalls, canopy and columns, trash areas and the store exterior. Windows, sandblasting, graffiti removal and bird netting can be added to the same visit.
Parking Lot Cleaning questions
Will pressure washing remove oil stains from my parking lot?
Hot water and degreaser remove most oil staining, and fresh stains usually come out completely. Old stains that have soaked deep into the concrete will be much lighter but may leave a shadow. Sandblasting can take off what washing leaves behind.
Does pressure washing damage parking lot striping?
Sound, well-bonded striping is fine. We lower the pressure over paint and thermoplastic. Striping that is already flaking may lose loose paint, which is one reason many owners schedule washing right before a restripe.
Do you clean multi-level parking garages too?
Yes. Parking structures have their own page and their own method: top down, one level at a time, with the wash water recovered. See our parking garage cleaning service.
Water Reclamation questions
Is it illegal to let pressure washing water go down the storm drain?
In California, wash water that carries pollutants such as oil, detergent, paint or debris is generally prohibited from entering storm drains under local stormwater ordinances and state water quality rules. Fines fall on the property owner as well as the contractor, which is why we recover the water.
Does water reclamation cost more?
It adds equipment and time, so yes, somewhat. It is far cheaper than a citation, and on most of the commercial sites we clean it is simply part of the job.
Where does the recovered water go?
It is filtered and either reused during the job or taken off site and disposed of in line with local requirements, typically to the sanitary sewer with approval or to a licensed facility.
Graffiti Removal questions
How fast can you remove graffiti?
Usually within 24 hours of your call, and often the same night. Send a photo and the address for the fastest quote.
Will graffiti removal damage the wall?
We match the method to the surface. Unpainted block and concrete clean up well. On painted walls, removing the tag can also lift some of the paint beneath it, and we will tell you before we start if repainting that area is the better option.
Can you remove graffiti from glass and signs?
Yes. Paint and marker on glass, metal and most sign faces is removed by hand with the correct remover. Etched glass cannot be washed out and needs glass repair.
Sandblasting questions
What is the difference between sandblasting and pressure washing?
Pressure washing cleans the surface with water and heat. Sandblasting uses abrasive media to remove a thin layer of the surface itself, which takes off stains, paint and rust that water cannot.
Will sandblasting damage my concrete?
Done correctly it leaves a clean, slightly textured surface. We test a small area first and adjust the media and pressure to the concrete.
Can you remove parking lot striping?
Yes. Blasting is one of the cleanest ways to remove old lines and curb paint before a new layout is painted.
Oil Spill Clean-Up questions
How quickly can you respond to an oil spill?
Call (714) 867-3418. We give you an arrival time on the phone and treat active spills as the priority job.
Can old oil stains be removed?
They can be greatly improved with degreaser and hot water, and sandblasting can remove what is left. Fresh spills clean up far better, which is why we tell customers to call right away.
What should I do before you arrive?
Keep people and cars off it, and if it is safe, put absorbent or cat litter on the liquid and block any nearby drain. Do not hose it down; that spreads the oil and sends it to the storm drain.
