DC Water Damage Emergency Checklist: First 24 Hours (Logistics)

This is a logistics checklist — the operational steps to take in the first 24 hours after water damage in the District: how to stop the water, who to call, what to document, and whom to notify. It deliberately does not cover drying technique, mold judgment, or “is it safe to stay” decisions; those are restoration questions, not logistics. The goal here is simple: contain the loss, build a record, and route it to the right people.

At a glance: the five logistics phases

Phase 1 — Make the scene safe

• Look before you step. If standing water touches outlets, the panel, cords, or appliances, assume an electrical hazard and stay out until power is off — ideally by a professional or only if the panel is dry and safely reachable.
• Smell for gas. A gas odor means leave and call 911 and the utility from outside. Do not flip switches.
• Keep people and pets clear of contaminated water (sewer backups are Category-defined contamination — treat them as hazardous and stay out).

Phase 2 — Stop the water at the source

The single most damage-limiting action is shutting the water off. Where the valve is depends on your building type:

• Single-family / rowhouse: the main shutoff is typically where the service line enters — near the meter, in the basement, or in a front utility area.
• Apartment / condo: there may be a unit-level shutoff plus a building main controlled by management.

The full, building-by-building walkthrough — including how to find and turn the valve, and what to do if you can’t — is on how to shut off your water in a DC home or apartment.

Phase 3 — Call the right number

Match the call to the cause. Calling the wrong line wastes time in an emergency.

The complete contact directory with hours and links is on the DC water emergency contacts desk, and the formal sewer/main-break reporting steps are on reporting a water main break or sewer backup.

Phase 4 — Document the loss (before you clean up)

This is the phase people skip under stress, and it is the one that most affects the outcome of a claim. Build the record before moving or discarding anything:

• Photograph and video everything — wide shots of each affected room, then close-ups of damaged building materials and contents. Capture standing-water depth against a wall or doorframe if safe.
• Note the time and source. Write down when you discovered it and what caused it (e.g., “supply line to water heater failed, ~6:40 a.m.”).
• Inventory damaged contents — make, model, and approximate value where you can. Keep receipts you have.
• Preserve the failed part if it’s safe — the burst hose, the cracked fitting — for the insurer and any plumber.
• Keep all repair and mitigation receipts from the start.

Phase 5 — Notify the right parties

With the scene safe and the loss documented, start the formal processes:

• Your insurer. Report the loss promptly. Standard homeowners and renters policies treat sudden internal water damage differently from flood (surface) water — flooding from outside is covered under the NFIP, not a standard policy. The NFIP’s how-to-file guidance and this site’s flood insurance in DC page explain which is which.
• Landlord or property manager / HOA. Renters and condo owners must usually notify management quickly; building systems and shared responsibility may be involved.
• Mortgage servicer, if the damage is significant — some claim payouts route through the servicer.

The 24-hour logistics checklist

Use this as the printable core. (Print this page; the layout is print-friendly.)

• Confirmed the scene is safe — no electrical or gas hazard; 911 if life is at risk
• Closed the water main shutoff (or confirmed source is public)
• Called the correct line — DC Water (202) 612-3400 / 311 / insurer
• Took wide and close-up photos and video before touching anything
• Wrote down the time, cause, and a contents inventory
• Preserved the failed part and kept all receipts
• Reported the loss to the insurer
• Notified landlord / HOA / mortgage as applicable
• Confirmed any plumbing or gas repair will be permitted (why this matters)
• Verified any contractor’s DC license on Scout
