Stormwater Got Inside: What's Salvageable and What Isn't

One principle does most of the work: can the material be cleaned all the way through, or did it absorb the water? Everything else follows from that.

The short answer

One principle decides most of it: can the material be cleaned all the way through? Non-porous items — tile, metal, glass, solid wood — generally come back. Porous items that absorbed the water — carpet pad, mattresses, upholstery, particle board — generally do not, because storm water is Category 3.

Sorting flood-damaged contents for salvage after storm water entered a Downey, CA home

First, the thing people find hardest to accept: storm water that came in from outside is Category 3 contaminated, regardless of how clear it looked. It crossed soil, roadway, and storm drain, and it carries what those carry.

That single fact drives every salvage decision below.

The principle

Generally salvageable

  • Tile, stone, sealed concrete, and glass
  • Metal furniture, appliances, and fixtures — though electrical items need assessment before being energized
  • Solid wood furniture, if dried promptly and properly; finishes may need attention
  • Dishes, glassware, and non-porous kitchenware, after proper cleaning and disinfection
  • Jewelry, coins, and hard non-porous valuables
  • Most hard-surface toys and household items

Generally not salvageable

  • Carpet pad — always, on any category of flood water
  • Carpet itself, on Category 3 water
  • Mattresses, pillows, and upholstered furniture
  • Particle board and MDF furniture, which swells irreversibly and loses integrity
  • Stuffed toys and soft goods that absorbed contaminated water
  • Drywall and insulation below the flood line
  • Cosmetics, medicines, and any food, including sealed containers that were submerged
  • Baby bottles, pacifiers, and children's feeding items

The judgment calls

ItemIt depends on
Clothing and textilesFrequently recoverable with hot-water laundering and appropriate disinfection; heavily soiled or delicate items may not be
Solid hardwood flooringSalvageable within about 24 hours with drying panels; permanent deformation after that
Kitchen cabinetsSolid wood doors and frames often survive; particle board carcasses usually do not
ElectronicsAssume loss if submerged; anything that got wet must be assessed before being powered on
Antiques and heirloomsSpecialist conservation is often worth it — do not discard before asking
Area rugsValuable rugs can sometimes be professionally restored; ordinary rugs rarely justify it

Documents and photographs: the exception

This is the one category where waiting actually helps, and where people throw things away that could have been saved.

Do not try to separate wet pages — they tear, and separation is a specialist process. Do not lay them out to air dry, which sets the damage. Instead, bag them and freeze them if you can. Freezing stops deterioration and biological growth and buys you weeks. Freeze-drying then recovers a surprising amount, including material that looks beyond hope.

Tell us at the first visit if there are documents or photographs that matter. It changes what we prioritize.

Document before you discard

Everything you throw out is part of your contents claim, and the claim is settled from your list rather than ours.

  1. Photograph each item, or each grouping where individual shots are impractical
  2. List item, room, approximate age, and replacement cost
  3. Keep receipts, credit card records, or listing links where you have them
  4. Note why disposal was necessary — contamination, structural failure of the material
  5. Ask your adjuster before disposing of anything substantial, or confirm they waive inspection

Safety while sorting

  • Waterproof gloves and boots, always — this is contaminated material
  • Do not sort in the affected area if there is visible mold growth; get it contained first
  • Wash hands thoroughly before eating, drinking, or touching your face
  • Keep children and pets out entirely
  • Do not run box fans in a contaminated area, which aerosolizes it into your air
  • Check your tetanus status if you are handling debris with metal or broken material in it

The part we take on

Structural decisions are ours — how far up the wall the drywall comes out, whether the flooring can be dried, what the framing needs. Contents decisions are collaborative, and we would always rather flag something as questionable and let you decide than throw out something that mattered to you.

If something is genuinely borderline, say so. There is often a specialist route for items with real value, sentimental or otherwise.

Frequently asked

Yes on a genuine flood loss, and the appearance is misleading. Water that crossed soil, roadway, or a storm drain carries bacteria and chemical contaminants you cannot see. The IICRC S500 standard classes it as Category 3, and porous materials that absorbed it cannot be reliably decontaminated. Carpet pad always goes; carpet effectively always goes.

The one category where waiting helps

Documents and photographs are the exception worth fighting for. Do not try to separate wet pages and do not lay them out to air dry — both set the damage. Bag them, freeze them, and tell your restoration crew. Freeze-drying recovers a surprising amount.

Everything you discard is part of your contents claim, so photograph and list it before it leaves the house — item, room, age, replacement cost. For sewage-contaminated items that genuinely cannot stay, document heavily and tell your adjuster why.

Structural decisions are ours; contents decisions are yours. We would always rather flag something as borderline and let you choose than throw out something that mattered to you.
