Commercial Building Power Washing in NYC

Why commercial exteriors need a program, not one-off cleanings

NYC exteriors take punishment year-round: soot from HVAC and street traffic, salt from winter sidewalk treatment, biological growth on shaded facades, grease trails from dumpster pads and receiving areas, and gum and grime on high-foot-traffic entrances. Once staining sets in, spot cleaning stops working — the whole surface needs to be reset. A quarterly or semi-annual power washing program keeps facades, sidewalks, and service areas presentable and pushes out the cost of restoration cleaning by years.

Common commercial scopes we clean

• Storefronts & entrances

  Sidewalk aprons, awnings, glass frames, entry mats, gum removal.

• Facades & multi-family buildings

  Brick, brownstone, stucco, EIFS, precast, and painted surfaces — soft-washed when needed.

• Parking garages & ramps

  Oil and tire mark reduction, deck cleaning, stairwell degreasing.

• Dumpster pads & receiving

  Degreasing, sanitizing rinse, odor reduction for back-of-house zones.

Scheduling around business hours

For most commercial properties we work between 10 PM and 6 AM to avoid customer disruption, blocked entries, and wet-surface liability during business hours. Retail corridors, restaurant rows, medical offices, and lobbies get an overnight window that lets surfaces dry before morning. For multi-family properties we coordinate with building staff on entry sequencing and posted notices so residents aren't caught by wet sidewalks.

NYC sidewalk & runoff considerations

Under NYC Administrative Code § 19-152, property owners are responsible for keeping the sidewalk in front of the property clean and in good repair. Commercial washing that discharges wastewater into the storm drain can also conflict with NYC DEP rules — especially at fuel islands, receiving docks, and dumpster pads. We use surface cleaners with recovery where discharge control is required, capture wash water when working near catch basins, and select detergents that break down without leaving film on adjacent glass and metal.

For historic districts (LPC-designated buildings), we default to soft washing on masonry — low pressure with a targeted cleaning solution — instead of high-pressure blasting that can damage mortar joints and brownstone faces.

Matching method to surface

A sensible maintenance cadence

• Monthly: dumpster pad & receiving degrease, entry gum removal
• Quarterly: sidewalks, storefront glass frames, awnings
• Semi-annual: facade rinse for street-facing brick / stucco
• Annual: full facade soft wash, parking garage deck clean
• As-needed: graffiti removal (within 24–48 hours to avoid staining)

What to expect on a first estimate

We walk the property with the manager, note the surfaces in scope, identify anything that needs soft washing rather than pressure, flag drainage or containment considerations, and confirm access and after-hours logistics. You receive a written estimate that itemizes each scope (facade, sidewalk, dumpster pad, etc.) so recurring items can be scheduled on their own cadence without re-bidding the whole property each visit.
