Why patio cleaning matters in Duncan
In Duncan’s dense suburban landscape, patio cleaning is essential to prevent the buildup of dirt, pollen, and mildew that accumulates quickly in the region’s humid climate. The work involves removing stubborn stains and grime from concrete, pavers, or stone surfaces, which can deteriorate faster in heavily populated areas due to constant exposure to foot traffic, vehicle exhaust, and seasonal debris. Regular cleaning maintains the appearance and longevity of outdoor spaces in a community where homes are closely spaced and curb appeal is highly visible.

What patio cleaning actually involves, step by step
Surface material check. Stamped, colored, or sealed concrete is identified separately from plain broom-finish concrete before pressure is applied, since a sealed or decorative surface can discolor or lose its finish under the pressure setting that plain concrete tolerates without issue.
Detergent application. A degreasing or stain-lifting solution is applied to oil spots, tire marks, and organic staining and left to dwell, since pressure alone tends to spread an oil stain outward into the surrounding concrete rather than actually lifting it out of the pores.
Surface cleaning pass. The surface is cleaned in overlapping passes with a surface cleaner attachment held at a consistent distance and angle, which produces an even result across the slab instead of the ringed or striped pattern a handheld wand leaves on a large flat area.
Edge and joint detail. Expansion joints, edges along garden beds, and corners the surface cleaner can't reach are finished separately at a lower pressure, since those areas are also where a wand held too close is most likely to etch a visible line into the concrete.
Rinse and runoff containment. The area is given a final clear-water rinse, and runoff containing detergent or lifted contaminants is directed away from storm drains and planting beds rather than left to flow wherever the slope of the driveway happens to take it.
What goes wrong when patio cleaning is done badly
Etching and striping from a close wand. Holding a pressure washer tip too close to bare concrete, or moving it too slowly, can etch a visible line or swirl pattern directly into the surface — a mark that doesn't wash out because it's physical erosion of the top layer of the slab, not dirt.
Discoloring sealed or stamped concrete. Sealed and stamped decorative concrete can lose its sheen or develop a blotchy, uneven look when cleaned at the same pressure used on plain broom-finish concrete, since the sealer layer itself is thinner and softer than the concrete underneath it.
Spreading oil stains instead of lifting them. Blasting an oil or grease stain with straight pressure and no chemical pre-treatment tends to push the stain outward into the surrounding pores of the concrete, turning a contained spot into a much larger faded halo that's harder to treat afterward.
What patio cleaning costs around Duncan
58 per square foot. It is based on a patio or deck surface with a moderate soil level. These numbers summarize public pricing research for this type of job rather than a quote from a specific company — actual pricing depends on the scope of the job and who is hired to do it.

How to choose who does the work in Duncan
Does the quote specify the PSI and method — pressure wash vs. soft wash — for each surface? The wrong PSI on siding, roofing, or wood can cause damage, so the method should be disclosed per surface, not left as one generic number. Is a written scope listing every surface included — driveway, siding, deck, roof, fencing — provided? Bundled pricing sometimes covers only one or two surfaces despite sounding comprehensive. Are the cleaning chemicals used, and their effect on nearby landscaping and pets, disclosed before the job? Soft-wash detergents vary in strength, and runoff can affect plants or pets nearby. Does the estimate distinguish concrete or driveway work from roof or siding work? Roof and siding washing typically require lower pressure and different technique than concrete, and pricing that lumps them together can hide risk. What is the policy if pressure washing reveals pre-existing damage, like cracked paint or loose mortar? Pre-existing conditions can surface once dirt is removed, so it helps to know how that gets handled before agreeing to the job. Is post-treatment sealing for driveways or decks included in the price or billed separately? Sealing is often an add-on, not part of a basic wash.
No mention of PSI or method — pressure vs. soft wash — for each surface. The wrong pressure on siding, roofing, or wood can cause real damage, and a quote that has not specified method per surface has not actually assessed the job. A price far below every comparable bid for the same square footage. An unusually low price can mean lower-grade equipment, no pre-treatment chemical, or rushed coverage that leaves streaking. No mention of what chemicals are used or their effect on landscaping. Undisclosed chemical strength is how plants and grass near the work area end up damaged. Full payment demanded before the job starts. Paying in full upfront removes leverage if streaking, missed spots, or damage shows up afterward. Pressure to add extra services on the spot without a separate written price. Add-ons proposed in the moment are harder to compare against other bids.
The work begins with an assessment of the patio’s material, condition, and level of soiling. Providers in Spartanburg, SC determine the appropriate pressure settings and cleaning agents, if needed, to avoid damage. Surface type and stain severity influence the approach taken.
