Standing in a flooded basement or water-damaged suite, it is tempting to start moving belongings immediately. First, protect people and prevent further loss. Then document what happened before cleanup changes the evidence. Knowing how to document flood damage gives your insurer, adjuster, property manager, and restoration team a clear record of the event and the work required to restore the property safely.
If water is near electrical equipment, outlets, appliances, or a breaker panel, stay out of the area and do not touch anything wet. If the source is a burst pipe and it is safe to do so, shut off the main water supply. Sewage backups, contaminated floodwater, and water entering from outside require extra caution because they may contain bacteria, chemicals, or other hazards. Keep children, pets, tenants, and unprotected staff away from affected areas.
Start Documenting Flood Damage Before Cleanup
Once the area is safe to enter, begin with wide photos and video. Record the property as it looks before water extraction, demolition, disposal, or moving furniture. A restoration crew may need to remove damaged materials quickly to prevent mold and structural deterioration, but clear documentation should happen first whenever conditions allow.
Use your phone to take a slow video walkthrough from the entrance of the property to every affected room. Narrate the date, time, address, apparent water source, and what you can see. For example, identify a failed supply line, an overflowing appliance, a roof leak, groundwater intrusion, or a sewer backup. Do not guess at the cause if you do not know it. State only what you observed, such as, “Water was flowing from beneath the kitchen sink at 6:30 a.m.”
Then take still photos from several distances. Wide images establish the location and scale of the loss. Mid-range photos show what was affected within each room. Close-ups capture water lines on walls, swollen baseboards, damaged flooring, stained ceilings, soaked insulation, and visible debris. Photograph the water source if it is visible and safe to approach.
Capture the details insurers need to see
Your documentation should show both the immediate damage and the conditions that could create later damage. Moisture behind walls, under flooring, or inside cabinetry may not be obvious in a photo, but visible staining, buckling, delamination, and water marks help establish why professional moisture testing and drying are necessary.
Include photos of these conditions when they apply:
- Water depth against a ruler, tape measure, or another clear point of reference
- The highest visible water line on walls, furniture, doors, and stored items
- Damaged mechanical equipment, appliances, electrical components, and built-in finishes
- The exterior entry point for water, such as a foundation crack, roof opening, blocked drain, or window well
- Labels, serial numbers, model numbers, and receipts for damaged equipment or higher-value contents
Take photos in good light when possible, but do not delay emergency mitigation to get perfect images. A slightly imperfect photo taken immediately is more useful than no record at all.
Build a Room-by-Room Flood Damage Inventory
Photos support your claim, but an inventory explains what each image shows. Work through the property one room at a time and create a written list of affected building materials and contents. For a home, that may include flooring, drywall, furniture, electronics, clothing, tools, and stored seasonal items. For a commercial property, include inventory, tenant improvements, equipment, documents, furnishings, and any interruption to operations.
For each item, record the room, description, brand or model if known, approximate age, original purchase price if available, and current condition. Use plain language: “oak dresser, lower drawers swollen and wet,” or “server cabinet in rear office, water reached bottom two inches.” Avoid throwing away damaged items until your insurer has advised you, unless they are unsafe, contaminated, or must be removed to protect the property.
When contaminated water is involved, do not sort through or clean porous items without proper protective equipment and direction from a qualified restoration professional. Upholstered furniture, carpeting, insulation, paper products, and some contents may not be safely recoverable after a sewage backup. Documentation matters, but health and safety come first.
Keep a timeline from the first discovery
A simple event log can prevent confusion later. Write down when the flood was discovered, when the water source was shut off, who was contacted, when emergency services or contractors arrived, and what actions were taken. Save call logs, emails, text messages, invoices, and emergency service reports in one folder.
Also record reasonable emergency expenses. This can include water extraction, temporary power protection, emergency plumbing repairs, dehumidifier rental, temporary relocation, or security measures after water damages a door or window. Keep original receipts and make a digital copy immediately. Insurance coverage and reimbursement rules vary by policy and cause of loss, so do not assume every expense is covered. Your records allow the insurer to assess the expense properly.
Preserve Evidence Without Letting Damage Spread
There is a real trade-off after a flood: waiting too long can allow mold growth, wood swelling, corrosion, and material failure, while cleaning too aggressively can make it harder to prove the original extent of damage. The practical approach is to document first, then begin reasonable emergency mitigation.
Do not leave standing water in place simply for an adjuster to see it. Take photos and video, retain samples or damaged components only when it is safe and appropriate, and arrange professional extraction and drying promptly. If a plumbing fitting, hose, or appliance component failed, keep the damaged part if possible. Place it in a labeled bag or container and photograph it before it is removed.
Avoid painting over stains, replacing flooring, tearing out drywall, or discarding major contents before your insurer has had an opportunity to review the loss, unless immediate removal is required for safety or to stop further damage. If emergency demolition is necessary, photograph the materials before and during removal and ask the restoration contractor to document moisture readings, affected areas, and disposal.
Report the Loss Clearly to Your Insurer
Contact your insurer as soon as possible after stabilizing the situation. Have your policy number, property address, date and time of loss, suspected cause, and a concise description ready. Ask for a claim number and write it in your event log. Use that number on emails, invoices, estimates, and photos going forward.
When describing the incident, be factual. Explain where water originated, which areas were affected, whether water was clean, gray, or sewage-contaminated, and what emergency steps were taken. If the source has not been confirmed, say so. A professional leak detection, plumbing, or restoration assessment may identify conditions that were not visible during the initial emergency.
Send organized files rather than an unmarked camera roll. Create folders by room or date, and name photos clearly when possible, such as “Basement-waterline-north-wall” or “Office-server-room-before-extraction.” This is especially helpful for condo properties, rental units, and commercial buildings where responsibility may involve an owner, corporation, tenant, property manager, or multiple insurers.
Extra Documentation for Condos and Commercial Properties
In a condo, notify property management or the building emergency contact right away, particularly when the water may have come from another unit, a common plumbing line, the roof, or a building system. Photograph your unit, but also document hallways, common areas, or neighboring spaces only if authorized and safe to do so. Keep copies of notices from management and any incident reports.
Commercial operators should document operational impact alongside physical damage. Record affected business areas, equipment downtime, stock loss, closures, canceled appointments, tenant disruption, and temporary relocation measures. Do not include private customer information or sensitive business records in claim photos. A clear operational log can support discussions about recovery priorities and any applicable business interruption coverage.
Let Professionals Document What Photos Cannot
A flood can look minor on the surface while moisture remains trapped beneath flooring, behind baseboards, inside wall cavities, or around electrical and mechanical systems. Professional documentation may include moisture maps, humidity readings, thermal imaging results, drying logs, equipment records, contamination assessments, and detailed scope-of-work reports. These records establish the technical basis for drying, remediation, removal, and reconstruction decisions.
GTA Restoration provides 24/7 emergency response across Toronto and the GTA, with restoration, plumbing, cleanup, and insurance documentation support coordinated under one response. Fast extraction and controlled drying can reduce secondary damage, but the work must be properly documented from the start.
The best time to organize flood evidence is while the details are still clear and before the property changes. Take the photos, start the timeline, save the receipts, and bring in qualified help quickly. That record can make the path from emergency to recovery far more manageable.
