Commercial Water Damage: A Business Continuity Playbook for the DMV

The first hour: stop, isolate, document

Shut off water at the nearest isolation valve, not necessarily the building main, so you can preserve service to unaffected tenants and operations. For multi-tenant buildings, the property manager should have an isolation map for every supply riser.

Cut power to wet areas at the panel before sending anyone in to clean. Commercial buildings have higher voltages and three-phase equipment that make electrical safety more critical than in residential losses.

Photograph and video everything before moving inventory, equipment, or fixtures. Take wide shots of each area, close-ups of damaged inventory, and the source of the failure.

Business interruption coverage

Business interruption (BI) and extra expense coverage pays for lost income and the extra costs of operating from a temporary location while your property is repaired. Most commercial policies include BI but the limits and waiting periods vary widely — typical waiting periods are 24 to 72 hours.

To make a BI claim, you need historical financial documentation: 12 to 24 months of P&L statements, sales records, payroll, and operating costs. Compile this in the first week — adjusters who request it later often slow the claim by months.

Containment that lets you stay open

A skilled commercial restoration company will set up containment to isolate the work area from the operating area. Plastic sheeting, negative air machines, and dedicated entrances let you keep selling, serving, or working while drying happens in the affected zone.

For restaurants, this often means keeping the kitchen and dining open while a damaged storage area dries. For offices, it means relocating affected workstations to conference rooms or unoccupied floors while the affected area dries.

Inventory: separate, document, dispose

Categorize affected inventory into three groups: undamaged (move to a dry area), salvageable (clean and document), and total loss (photograph, list, and dispose with carrier approval). Do not throw anything out without photographing it and documenting it in writing — the carrier needs proof for the contents portion of the claim.

For food-service businesses, any food that contacted floodwater or sat in a warm walk-in during a power loss must be discarded per health code. Get a health-inspector letter documenting the loss; it strengthens the claim.

Equipment, electronics, and HVAC

Commercial electronics, point-of-sale systems, server racks, and refrigeration require specialty restoration — not the same crew that dries the carpet. Acidic moisture continues to corrode circuit boards for days. Get electronics into specialized restoration within 48 hours.

HVAC systems that ran during the loss often spread moisture and contamination throughout the building. Shut down HVAC immediately when water is found and have it inspected before restarting.

Tenant and lease implications

Multi-tenant buildings have specific obligations under most commercial leases — landlords typically must restore base building, tenants are responsible for tenant improvements and personal property. Pull the lease and review repair obligations and rent abatement clauses early.

Communicate with every affected tenant in writing within 24 hours: what happened, what is being done, expected timeline, and impact on their space. Lack of communication is the single biggest source of tenant disputes after a loss.
