Matching the method to the surface
We clean the outside of commercial and industrial properties across Southern California: buildings, concrete, parking structures, loading docks, walkways, bin areas and glass. Different surfaces need different treatment. Too much pressure on the wrong surface causes damage that costs more to put right than the cleaning did, so we match the method to the surface.
Matching the method to the surface
Four methods cover almost everything on a commercial property. We will tell you which your surfaces need after we look at them. High pressure Hard surfaces that take a beating: concrete, parking structures, loading docks and service yards. Hot water and steam Where the mess is grease or oil, around food service and loading areas. Soft washing Painted walls, render and signage, where pressure would strip the finish. Targeted removal Graffiti, gum and glue, taken off without damaging what is underneath.
How often to clean
Not everything on a property needs the same schedule. Most sites end up with a mixed one under a single agreement, which makes the cost predictable instead of arriving as one-off bills. Entrances, food areas and bin stores need the most frequent attention Car parks and service yards sit somewhere in the middle Building fronts usually have the longest gap between cleans Coastal properties need more frequent attention than inland ones
Working around an open property
Almost all of this work happens while the property is trading. We plan the work so your visitors and tenants are not disrupted. We work around your trading hours Walkways stay usable while we work Overnight or phased work where daytime access does not suit Water is contained and collected, not left to run into the drains
Scheduled beats reactive
A schedule costs less than an emergency callout. Our crews set a cleaning interval around your traffic, your surfaces and your operating hours, then hold to it.
How a job runs, start to finish
Site Walkthrough
A supervisor walks the property with you and records surface types, square footage, drainage points, access hours and any existing damage.
Written Scope
You get a written scope within 24 hours naming the cleaning method for each surface, with a fixed price set against it. Nothing is scheduled until you approve it.
Scheduling
The work is booked into your operating hours, usually overnight or before opening, so parking, loading and foot traffic keep moving.
Work and Record
Our own crews do the work, with drains covered and runoff recovered, and you receive dated photographs and the disposal record afterwards.
What we need from you
To give you a price we need a few details. If you are not sure about some of it, we will confirm it when we look at the property.
- The property address and roughly how big it is
- Which surfaces need cleaning, and their condition
- Whether the property is open while we work
- Anything affecting access, such as height, gates or lifts
What our clients say
“We had an issue with water draining in the trench drain and a clogged pipe preventing water to drain to the street at our dealership… Responsive, attended a last minute call, convenient to work with and makes sure you are satisfied.”
“I reached out to PowerWashCo last minute for drain cleaning services, and I couldn’t be happier with the outcome… Not only did they efficiently vacuum the hazardous oil residue and clear the flooded storm drain, they also pressure wash our gas station that night.”
“We needed our 7-11 gas station’s gas island and canopy cleaned, and we came across PowerWashCo on Google. After reading the reviews, I decided to take a chance on them, and I’m glad I did… I highly recommend PowerWashCo for your cleaning needs.”
