What restaurant exterior washing actually involves, step by step
Surface and plant protection. Landscaping near the foundation is wetted down and covered, and any exterior outlets or fixtures are bagged, before a single nozzle is turned on, since cleaning solution runoff and overspray cause more complaints on siding jobs than the wash itself.
Detergent pre-treatment. A cleaning solution formulated for the siding material — vinyl, wood, stucco, or fiber cement each take a different mix — is applied at low pressure and left to dwell, breaking down algae and mildew chemically instead of relying on pressure to blast it off.
Soft-wash rinse. The siding is rinsed at low pressure, generally under 500 psi through a wide-fan tip, working top to bottom in overlapping passes at a consistent speed, since an inconsistent pass speed is what leaves uneven streaking behind on the finished surface.
Spot treatment. Areas with heavier algae staining or stubborn mildew get a second, more concentrated pass rather than higher pressure, because raising the pressure to compensate for a stain is what pushes water behind siding seams instead of just cleaning the surface.
Final rinse and inspection. A clear-water final rinse removes any remaining detergent residue, and the finished siding is walked and checked in daylight for spots the first pass missed and for any panel that shows lifting or damage that needs separate attention.
What goes wrong when restaurant exterior washing is done badly
Uneven pass speed streaking. Moving the wand at an inconsistent speed across siding leaves a banded, uneven-looking streak pattern sometimes called zebra striping, where the panels that got a slower pass look cleaner than the ones the operator moved past quickly. It's a technique problem, not a chemistry problem, and it shows up worst on light-colored vinyl.
Forced water behind siding. Aiming a pressure washer wand directly into a siding seam or up under a lap edge can force water behind the panel instead of just cleaning its face, and water trapped there is a documented cause of mold growth and rot inside the wall cavity that isn't visible until much later.
Wrong pressure for the material. Vinyl, stucco, and fiber cement each tolerate different pressure levels, and using a pressure setting suited to concrete on siding can crack stucco, split vinyl seams, or strip the factory finish off fiber cement panels well before it makes the surface look any cleaner.
What drives the cost of restaurant exterior washing around Duncan
Commercial or institutional pressure washing around Duncan tends to be quoted per project rather than from a posted price range — most providers need to see the site first. The main drivers behind a quote like this: the total square footage across multiple buildings, a parking structure, or a lot, rather than a single house; water reclamation or containment requirements that many municipalities impose on commercial sites; scheduling around business hours or foot traffic, since storefronts and clinics are usually washed outside operating hours; for fleet washing specifically, the number of vehicles and whether they are washed on a recurring schedule. This reflects how this category is generally priced across the market, not a quote from a specific company — the real number for a project depends on its scope and the provider chosen.
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 scope of work is typically assessed by evaluating the size of the area, surface materials, and the level of staining or contamination. Accessibility, local regulations in Spartanburg, SC, and any special considerations for food service establishments may also be factored in.
