Who They're For and What They Solve
Concrete cleaning is the removal of embedded dirt, organic growth, and chemical staining from porous concrete using calibrated pressure, heated water, and targeted pre-treatment chemistry. Because concrete absorbs contaminants rather than shedding them, rinsing alone accomplishes almost nothing. The soiling has to be lifted out of the pore structure itself.
Property owners need this service once concrete stops looking gray. Common triggers include listing a property for sale, a spring reveal of winter buildup, an oil spot spreading under a vehicle, algae film forming in shaded sections, or a white mineral bloom appearing across the slab after wet weather.
Left alone, staining does more than look bad. Organic growth holds moisture against the surface and creates genuine slip risk. Oil penetrates deeper the longer it sits and becomes harder to draw back out. Professional concrete cleaning restores appearance, reduces liability, and costs a fraction of replacing the slab.
Is It Time?
Most people notice one of these before they call us.
Our Services
Concrete cleaning is not a single technique. We select the method that matches the staining actually present on your surface.
A rotating-arm surface cleaner moves across open slab at consistent pressure and consistent speed. This is what prevents the striping and wand marks that DIY jobs leave behind. It handles general dirt, weathering, and traffic grime across large areas evenly.
Heat breaks the molecular bond between petroleum and concrete in a way cold water simply cannot. We bring water temperature up for oil spots, grease, transmission fluid, and food-service residue. This is the difference between lightening a stain and lifting it.
Organic growth, rust, and efflorescence each need their own chemistry. We apply the correct degreaser, rust remover, or biological treatment, allow proper dwell time, then rinse. Killing growth first stops it from returning within weeks.
A penetrating sealer applied to clean, dry concrete blocks future absorption. Spills sit on top instead of soaking in, and organic growth loses its foothold. This is optional, quoted separately, and roughly doubles how long the clean finish lasts.
Not sure which approach your situation needs? We assess first and recommend only what’s necessary, no upsells.
Why Homeowners Choose Mr. Local Services
We measure, quote by square foot in writing, and hold that number. No hourly meter, no change orders after we see the surface, no additional charges on completion day.
Fifteen years of calibrating PSI to the specific slab in front of us. Aged concrete, stamped finishes, and coated surfaces each get different settings rather than one aggressive default.
If any section dries uneven or shows wand marks, we come back and correct it at no charge within seven days. In writing, on every quote.
Surface cleaner for the open slab, hand wand for perimeters, corners, and expansion joints. The borders get the same attention as the middle.
How It Works
Call 951-458-6466 and tell us the approximate square footage and what the staining looks like. We return a firm written quote within 24 business hours.
On arrival we move furniture, cover nearby plantings and fixtures, and confirm water access. Pre-treatment chemistry goes down and dwells while prep continues.
Surface cleaner across open slab, hot water on petroleum staining, hand wand on all edges and joints. Most residential jobs finish in two to four hours.
We inspect the dried surface with you before leaving. Anything uneven gets corrected then, or within seven days under the streak-free guarantee.
Pricing
Concrete cleaning is priced by square footage, and the range runs $0.18 to $0.45 per square foot. A typical residential slab of 600 to 1,000 square feet lands between $150 and $400.
Four factors move you within that range: total square footage, stain severity and type, surface accessibility, and water source availability. Heavy oil or rust requiring hot water and specialty chemistry prices at the upper end. General weathering on open, accessible slab prices at the lower end.
Optional sealing adds $0.35 to $0.70 per square foot and is always quoted as a separate line item you can decline.
Every quote is flat-rate and confirmed in writing before any equipment comes off the truck.
Not at correctly calibrated pressure. Damage comes from excessive PSI held too long in one spot, which is exactly what surface cleaner equipment prevents.
Typically 12 to 18 months on unsealed concrete, depending on shade, drainage, and traffic. Sealing roughly doubles that window.
Most fade substantially with hot water and degreaser. Stains older than several years often lighten dramatically rather than disappear entirely, and we tell you that upfront.
Between $0.18 and $0.45 per square foot, so most residential jobs fall between $150 and $400. Call 951-458-6466 for a firm written number.
No. Sealing is quoted separately so you can decide after seeing the cleaned surface.
Not required. We need water access and a clear surface. Most customers approve the quote and leave us to it.
Yes. Larger properties with parking areas, loading zones, or walkway networks are usually quoted under commercial pressure washing , where we price by total square footage and can schedule after business hours.
Tell us the square footage and what the staining looks like, and we’ll have a firm written number back to you within 24 business hours. Every job carries our streak-free guarantee.
