Case Study: Commercial Strip Mall Pressure Washing in West Columbia, SC

A strip mall owner in West Columbia contacted us after two tenants complained that the building’s exterior appearance was negatively affecting their foot traffic. The 6-unit strip mall on Augusta Road had not been professionally pressure washed in 3+ years.

Sidewalks were darkened to near-black with ground-in dirt, chewing gum, and beverage stains from the coffee shop tenant. The building’s painted block and stucco facade had heavy green algae on the north-facing side. Parking lot curbs were barely visible under dirt and grass overgrowth. The dumpster pads had grease buildup creating odor issues.

A vacant 7th unit had been on the market for 4 months with no serious inquiries. The broker had specifically mentioned the building’s exterior as a factor.

Commercial pressure washing differs from residential in three critical ways: scale requires hot water equipment (200+ degrees F) and higher-volume pumps, scheduling must work around business hours, and environmental compliance matters near storm drains.

We scheduled work in two sessions: early morning (6-9 AM) for sidewalks and building facade, and evening (6-10 PM) for parking areas and dumpster pads. This eliminated any disruption to tenant operations.

We mapped all storm drain locations and planned wash patterns to direct water through our vacuum recovery system.

Used a hot-water pressure washer at 200+ degrees F with a 24-inch surface cleaner for the 2,400 sq ft of sidewalk. Hot water dissolves chewing gum on contact, breaks down grease, and removes embedded organic matter that cold water cannot penetrate.

Pre-treated all gum deposits with a gum remover solution (15 minutes dwell time). This strip mall had an estimated 200+ gum spots concentrated near the coffee shop and ice cream shop.

Surface-cleaned the entire sidewalk in overlapping passes. The concrete went from black-gray to original light gray. The coffee shop owner came outside during cleaning and asked if we could also clean in front of the neighboring business. Cleaned ADA tactile warning strips at crosswalks without damage.

Soft washed the approximately 4,000 sq ft stucco and block facade at 500 PSI with sodium hypochlorite. Commercial buildings with painted block cannot tolerate high pressure without paint loss.

Two passes on the north-facing wall (heaviest algae), single pass on east, west, and south. Rinsed all window frames, awning edges, and signage. Applied algaecide treatment to the north wall to extend time between cleanings.

Degreased and pressure washed all 28 parking spaces using hot water at 3,000 PSI. Cleaned and re-exposed painted curb markings (fire lane, handicap, no parking) that had been completely obscured by dirt buildup.

Removed grass overgrowth from expansion joints and curb edges. Dumpster pad required three passes with commercial degreaser and hot water at 3,500 PSI. Applied sealant to the dumpster pad after cleaning to make future maintenance easier.

Commercial pressure washing near storm drains requires wash water containment per EPA and SCDHEC regulations. We use vacuum recovery systems that capture wash water before it reaches storm drains. The recovered water is disposed of per local regulations.

This matters because liability falls on the property owner, not the contractor, if contaminated wash water enters storm drains. Fines can exceed $25,000 per violation. Our commercial pricing includes environmental compliance as standard.

Both complaining tenants withdrew their lease non-renewal notices after the cleaning. Within 6 weeks, the vacant 7th unit signed a new tenant who cited the building’s clean appearance as a factor.

The owner signed an annual contract: quarterly sidewalk cleaning, semi-annual building wash, and quarterly dumpster pad degreasing. The annual program cost is less than one month’s rent on the unit that was filled.
