Patio Pressure Washing in Cumming, GA
Remove algae, red clay, and embedded stains from concrete, stone, and paver patios across Forsyth County with professional patio pressure washing.
Why Patios in Cumming Get Dirty So Fast
Your patio is covered in green algae, slippery after every rain, and stained with red clay that will not rinse away with a garden hose. This is what happens to outdoor surfaces in Cumming, GA when Forsyth County's climate goes to work on concrete, pavers, and stone. The combination of over 56 inches of annual rainfall, sustained summer humidity, and red Georgia clay creates conditions that deteriorate patio surfaces faster than most homeowners expect.
Georgia's humidity and the shade created by mature hardwood trees common across Cumming neighborhoods accelerate biological growth on patio surfaces. Algae, mold, and mildew thrive on surfaces that stay damp — and patios adjacent to homes, pool areas, and tree lines rarely dry completely between rain events during the warmer months. What starts as a faint green film in spring becomes a dark, slick biological layer by midsummer that is both unsightly and a genuine slip hazard.
Paver patios present unique cleaning challenges because the joint sand between pavers traps organic debris, dirt, and clay particles that feed biological growth from below the surface. Concrete patios absorb red clay into their pore structure, creating staining that bonds chemically with the surface and resists standard rinsing. Each material requires a different pressure setting and pre-treatment approach to clean effectively without damage.
Pool deck patios deal with an additional set of challenges — extra moisture from splash zones, calcium deposits from pool water chemistry, sunscreen and body oil residue, and accelerated algae growth from the sustained dampness around the pool perimeter. These surfaces need more frequent cleaning and a specific approach that accounts for proximity to pool water.
How OCB Pressure Washes Patios in Cumming, GA
Every patio pressure washing job starts with a surface inspection. We identify whether your patio is poured concrete, concrete pavers, natural stone, flagstone, or brick. Each material has a different pressure threshold, chemical tolerance, and joint configuration. Using the wrong settings on any of these surfaces causes damage that is expensive to repair — etched concrete, chipped paver edges, dislodged joint sand, or stained natural stone.
We apply different techniques based on your specific surface. Concrete patios get full commercial-pressure treatment with a surface cleaner attachment that distributes water evenly and prevents the streaking that direct-wand washing creates. Paver patios get calibrated pressure with careful attention to joint lines. Natural stone gets a gentler approach with stone-safe cleaning solutions that lift staining without altering the stone's natural color or texture.
Pre-treatment is applied before any pressure washing begins. Biological growth gets a biocidal solution with dwell time to kill algae and mold at the root level. Red clay staining gets a targeted treatment that breaks the chemical bond between iron oxide and the surface material. Oil and grease spots from grills and outdoor furniture get a commercial degreaser. Skipping pre-treatment and going straight to pressure is one of the most common reasons DIY patio cleaning delivers underwhelming results.
After the pressure washing pass, we rinse the entire patio from the highest point down, carrying all loosened material off the surface. We check joint lines on paver patios and re-sand any areas where sand was displaced. We do a final walkthrough to confirm complete, even coverage across the entire surface. If any staining did not respond fully, we explain why and discuss your options before we leave.
Frequently Asked Questions
Everything you need to know about patio pressure washing.
Yes, when done correctly. Pavers require a different approach than poured concrete. The key is using the right pressure setting and keeping the nozzle at the correct distance and angle to avoid dislodging joint sand or chipping paver edges. We use a surface cleaner attachment that distributes pressure evenly across the paver surface rather than concentrating it through a direct wand. After washing, we check joint lines and re-sand any areas where sand was displaced during the cleaning process.
Most patios in Cumming need pressure washing once a year. Forsyth County's combination of humidity, red clay runoff, and heavy pollen season means patio surfaces accumulate buildup faster than drier climates. Patios with heavy shade from mature trees may need cleaning twice a year because algae and mold establish faster on surfaces that stay damp. Pool deck patios that deal with extra moisture and chemical splashing may also benefit from more frequent service.
Yes. Red clay is the most common patio staining issue we address across Forsyth County. The iron oxide in Georgia red clay bonds chemically with concrete and paver surfaces, making it resistant to standard rinsing. Professional pressure washing with appropriate pre-treatment breaks that bond and lifts the clay out of the surface pores. The results are dramatically different from what a garden hose or consumer pressure washer can achieve on red clay staining.
Not when done with the correct technique. Joint sand in paver patios and grout in stone patios can be displaced by improper pressure washing — typically from using too high a PSI or holding the nozzle too close to the surface. We use calibrated pressure settings and surface cleaner equipment designed to clean the paver face without disturbing the joints. If any joint sand is displaced during cleaning, we re-sand those areas before finishing the job.
Absolutely. Pool deck patios are one of our most common service calls in Cumming. Pool decks deal with extra moisture from splash zones, calcium deposits from pool water chemistry, algae growth accelerated by sustained dampness, and sunscreen and body oil residue. We adjust our cleaning approach for pool deck surfaces and use solutions that are safe for areas adjacent to pool water. We take care to direct runoff away from the pool during the cleaning process.
A standard residential patio in Cumming takes one to three hours depending on the total square footage, the surface material, and the severity of the staining. Larger patios with heavy red clay buildup or deep biological growth take longer because pre-treatment needs adequate dwell time before pressure washing begins. We give you a time estimate before starting and coordinate scheduling so the work fits your day. You do not need to be home as long as we have access to a water spigot.
