West Columbia's mix of humidity, pollen, river-bottom moisture, and clay soil means siding, driveways, and decks build up algae, mildew, and dirt fast. Pressure washing and exterior cleaning covers house washing (siding, brick, stucco), concrete cleaning for driveways and walkways, deck and fence washing, roof soft washing, gutter brightening, and sometimes fleet or dumpster pad cleaning for commercial properties. We track 8 businesses in this category serving the area.
What's actually involved
A proper job starts with an assessment of surface type, because brick, vinyl siding, wood decking, and concrete each need different pressure levels and cleaning agents. High-pressure blasting on the wrong surface strips paint, gouges wood, or etches soft mortar joints. Most reputable crews use "soft washing" (low pressure plus a cleaning solution) on siding and roofs, and reserve higher PSI for concrete and hard masonry. Expect pretreatment for mildew and algae, rinsing, and sometimes a sealant option for driveways and decks afterward.
What to look for before you hire
- Insurance and proof of liability coverage, since pressure equipment can damage windows, siding, and landscaping if mishandled.
- Clear explanation of PSI and chemical mix used per surface, not a one-setting-fits-all approach.
- Written estimates that specify square footage covered and what's excluded (second-story reach, oil stain removal, etc.).
- Care around plants, outdoor outlets, and pet areas.
