The short answer

Start with Photos and Video

Begin documentation as soon as it is safe to do so. Take wide shots to show the overall extent of the flooding, then close-up photos of specific damage. A video walkthrough is very useful, narrating what you see as you pan slowly across the room. Capture images of the water line on walls and furniture to prove the depth at its worst point.

Focus your camera on the source of the water, if you can identify it. This might be a crack in the foundation, a window well, or a backed-up floor drain. Photograph any damaged personal property, including furniture, electronics, and boxes of stored items. Do not move items until after you have recorded their condition, unless they are in immediate danger of further damage.

Create a Detailed Inventory List

Make a written list of every item that is wet, stained, or otherwise affected. For each item, note the brand, model, age, and an approximate value if you know it. Describe the damage in simple terms, such as 'soaked carpet' or 'warped wooden cabinet.' This list supports your photos and provides a clear record for your insurance adjuster to review.

Be thorough and include even small items. Group similar things together, like '12 hardcover books' or 'a box of winter clothing.' If you have receipts, manuals, or pre-loss photos for major items, gather them in a safe, dry place. This inventory is a critical piece of evidence for establishing the scope and value of your loss after a heavy rain event.

  • Furniture: couches, chairs, tables, shelving units.
  • Electronics: televisions, computers, speakers, gaming consoles.
  • Flooring: carpet, padding, laminate, tile.
  • Personal belongings: clothing, books, photo albums, toys.
  • Appliances: water heater, furnace, washer, dryer.
  • Building materials: drywall, baseboards, insulation, doors.

Protect Important Documents

Water can quickly ruin paper records you need for your claim. Locate insurance policies, mortgage documents, and identification. If they are wet, carefully separate the pages and lay them flat to air dry in a clean area. For documents that are already damp, avoid stacking them, as this can cause ink to run and pages to stick together permanently.

If you have many important papers, consider placing them in a sealed plastic bin for safe storage. You can also take clear photographs or scans of critical documents as a backup. This step helps ensure you have the necessary paperwork to communicate effectively with your insurance company during the claims process after a basement flood.

Note the Cause and Conditions

Write down the date and time you first noticed the flooding. Note the weather conditions, including how much rain fell and over what period. If the water entered from a specific point, like a window or a crack, describe that in your notes. This information helps establish that the flood was a sudden event caused by the rainstorm.

Observe and record the type of water. Clean water from rain is different from gray water that may have backed up from a drain. Mention any steps you took to try to stop the water, such as placing sandbags or using a wet-dry vacuum. Your notes create a timeline that supports the facts shown in your photographs and videos.

What to Do After Documenting

Once you have thorough documentation, contact your insurance company to start your claim. Share your photos, videos, and inventory list as they request. Keep a copy of everything you submit for your own records. You should also take steps to prevent further damage, like moving salvageable items to a dry area, but only after they have been fully documented.

A water damage inspection by local water damage pros can provide a professional assessment of the moisture in your walls and floors. This report can be valuable evidence for your claim. Remember, policies vary, and your insurer decides what is covered. Acting quickly to document and mitigate damage supports your financial recovery.

  • Contact your insurance provider to report the loss.
  • Save all correspondence with your adjuster.
  • Keep damaged items until the adjuster says you can dispose of them.
  • Get a professional moisture inspection for your records.
  • Begin water extraction and drying to prevent mold.
  • Review your policy to understand your deductible and limits.

Frequently asked questions

How long do I have to file a claim after a flood?

You should notify your insurer as soon as possible. Most policies require prompt notice, often within a few days of discovering the damage. Check your specific policy documents for the exact timeframe to avoid any potential issues with your claim's acceptance.

Should I start cleaning up before the insurance adjuster's inspection?

You should document everything first with photos and video. Then, you can take reasonable steps to prevent more damage, like removing standing water. Do not make permanent repairs or throw away damaged items until the adjuster has seen them, unless they pose a safety hazard.

What if I don't have receipts for damaged items?

You can still make a claim. Use old photos, credit card statements, or owner's manuals as proof of ownership. Provide a detailed description and the approximate age of each item. Your adjuster will work with you to establish a value based on the available information.
