Preparing Your Property for a Commercial Cleaning Crew

The Preparation Gap

When a commercial exterior clean underperforms, the cause is usually access rather than method. Vehicles were parked in the area to be cleaned. The water spigot did not work. Nobody had the gate code. The crew arrived at ten and the tenant's deliveries started at eleven. Each of these converts a planned job into a partial one, and the property is charged for the visit either way.

Preparation is inexpensive and it is nearly always the property's responsibility rather than the contractor's, because it depends on information and authority only the property has. A short checklist handled in advance is the difference between full coverage and a return visit.

Access and Clearance

The single largest cause of incomplete coverage is vehicles. Concrete beneath a parked car cannot be cleaned, and on a parking-heavy scope the difference between a cleared lot and a half-full one is the difference between a finished job and a patchy one.

• Notify well ahead. Several days, not the night before, and posted at the affected area rather than only emailed.
• Provide relocation guidance. Tell people where to park instead. Notices that only say "do not park here" produce confusion and non-compliance.
• Arrange cones or barricades the evening before, which is far more effective than a sign alone.
• Confirm gate codes, key access, and alarm arrangements, including for after-hours work when nobody is on site.
• Identify a contact reachable during the work window — a phone number that is answered at 2:00 AM if the work is overnight.

Water and Power

Commercial cleaning equipment needs a reliable water source and, depending on the setup, power. These are worth verifying rather than assuming, particularly at properties where exterior spigots are rarely used.

• Confirm the spigot works and delivers adequate flow — not merely that one exists. Long-unused exterior spigots frequently do not.
• Identify its location relative to the work area, since distance affects setup and may require additional equipment.
• Check whether water is metered separately or sub-metered to a tenant, which occasionally matters for cost allocation.
• Verify exterior power availability where required, and whether circuits are live after hours.

Drainage Information

Where the site's drains go is genuinely useful information and the property is usually the only party who has it. Knowing which inlets connect to the storm system and which to the sanitary sewer allows the crew to plan containment properly rather than treating every drain as unknown. If site drainage plans exist, making them available before the visit is one of the more valuable preparatory acts available.

Notifications Beyond Parking

Different occupants need different warnings, and the ones nobody thinks of are usually the ones that generate complaints.

• Tenants and residents: timing, affected areas, parking, and when access is restored.
• Anyone with windows onto the work area: to keep windows closed, particularly where elevations are being washed.
• Ground-floor and adjacent businesses: so they can protect merchandise, outdoor displays, and patio furniture.
• Security and after-hours staff: so crew presence at 3:00 AM does not trigger a response.
• Landscaping contractors: to avoid scheduling collisions in the same areas.
• Pet owners in residential settings: a routinely forgotten notification that reliably produces complaints.

Physical Preparation on the Day

• Remove or secure loose items — patio furniture, planters, signage, displays, mats, and anything that will be in the way or damaged.
• Empty and reposition waste containers where enclosures are in scope, ideally timed just after a pickup.
• Close windows and exterior doors in the work zone.
• Cover or relocate sensitive equipment, including electrical fixtures where relevant.
• Flag known problem areas — a fixture that leaks, a door that admits water, a crack that channels runoff somewhere unhelpful.

Set Expectations Before, Not After

A brief walk-through with the contractor before work begins prevents most post-job disagreements. Two things are worth establishing explicitly: which stains are expected to clear completely, which will lighten, and which are permanent; and what the scope does not include, since exclusions are where disputes originate. Photographing pre-existing damage — cracks, spalling, prior repairs, missing sealant — protects both parties, because a cleaned surface reveals conditions that were previously hidden and it is genuinely difficult afterward to establish whether they predate the work.

Timing Considerations

Surfaces need to dry before they are reopened, and drying takes longer than most schedules assume — particularly in shaded areas, in cool weather, and in enclosed structures with limited airflow. Building realistic drying time into the reopening plan avoids both slip exposure and the frustration of an area released too early. Where work is weather-dependent, agreeing in advance how postponement will be decided and communicated saves a difficult conversation on a rainy morning.

A Short Pre-Visit Checklist

• Notifications sent, posted, and specific about relocation
• Area cleared and coned the evening before
• Access, gate codes, and after-hours contact confirmed
• Water source tested; power availability verified
• Drainage information provided
• Loose items removed or secured
• Pre-existing conditions photographed
• Scope, exclusions, and realistic outcomes confirmed in writing
• Drying time and reopening plan agreed
