Stormwater Got Inside: What’s Salvageable After a Flood and What Isn’t
Storm water is contaminated water. That single fact decides most of the keep-or-discard questions you are about to face.
After Category 3 water — sewage, or flood water that has touched the ground — carpet, pad, mattresses, upholstered furniture, particleboard furniture and any food that was not sealed all go. Drywall and insulation the water reached come out too. Hard, non-porous items can be cleaned and disinfected. The rule is porosity: if contaminated water soaked into it, it cannot be reliably disinfected.
After a storm flood, everything looks salvageable if you rinse it. That instinct is understandable and it is usually wrong.
Water that has crossed the ground is Category 3 — contaminated — regardless of how clear it looks. It carries soil bacteria, landscape chemicals, and whatever was on the street. That reclassifies every porous item it touched.
Photograph everything before you decide anything
Nothing goes in a skip before it has been photographed in place. Individually, with make and model where relevant.
Then keep items until an adjuster has seen them or expressly released them. Where health risk makes storage impossible, photograph thoroughly, retain a labelled sample where safe, and get written agreement to dispose. Undocumented disposal is the most common reason legitimate contents claims get reduced.
Discard — no realistic path to saving
- Carpet pad. Always, without exception, after any category of flood water.
- Mattresses, box springs and pillows.
- Upholstered furniture that absorbed flood water into the frame and filling.
- Particle-board and MDF furniture and cabinet bases that have swollen.
- Insulation of any kind that got wet.
- Food, including anything sealed that was submerged — seals are not reliable against contaminated water.
- Cosmetics, medicines and baby items that contacted the water.
- Paper, books and cardboard that were saturated.
- Toys and items with porous surfaces or enclosed voids that cannot be cleaned inside.
Assess professionally — sometimes saveable
- Carpet face, which can occasionally be salvaged after Category 2 water caught quickly. After true flood water, generally not.
- Solid wood furniture, which can often be saved if dried slowly and correctly. Rapid drying causes splitting.
- Hardwood and engineered flooring, where mat drying may recover it if reached early.
- Appliances, which need electrical inspection before any use. Motors and control boards that were submerged usually do not recover.
- Documents and photographs, which can be freeze-dried by specialists. Get them frozen quickly to stop deterioration while you arrange it.
- Clothing and textiles, most of which survive commercial laundering with appropriate sanitising.
Usually saveable with cleaning and disinfection
- Hard non-porous surfaces: tile, sealed concrete, glass, metal, glazed ceramics.
- Solid plastics with no enclosed voids.
- Metal cookware and utensils, after washing and sanitising.
- Jewellery, ceramics and glassware.
- Sealed stone and quartz worktops.
The building itself
The same logic applies to the structure. Carpet pad goes. Drywall is cut back above the water line, because gypsum wicks upward and the paper facing is organic. Insulation in the affected cavity is removed. Base cabinets with particle-board bases usually go; solid wood or plywood boxes may survive.
What stays — framing, slab, hard surfaces — is cleaned first, then disinfected. That order is not a detail. A disinfectant applied over soil does not work, which is why "we sprayed it" is not the same as "we cleaned and treated it".
What sentimental items deserve
Photographs, documents and irreplaceable items are worth a different calculus. Rinse gently in clean water, do not attempt to separate stuck photographs, and freeze them in a sealed bag as soon as possible. Freezing halts deterioration and buys weeks to arrange specialist freeze-drying.
Tell your restoration crew what matters to you at the start. Items that would otherwise be triaged as damaged contents can be set aside and handled differently, but only if someone knows.
How to run the triage without losing the claim
The practical problem is that you need the contaminated material out of the building quickly and you need it documented before it goes. Those two pressures pull against each other, and the way to resolve them is to work in one direction through the house rather than dashing between rooms.
Start at the furthest affected point and work back toward the exit. Photograph each item where it sits, then move it to one of three staging areas: keep, professional assessment, and discard. Keep the discard pile outside and under cover if you can, and do not put it in a skip until you have written agreement.
Label the discard pile by room. When an adjuster asks what came out of the family room three weeks later, a labelled pile and a set of timestamped photographs answers the question in thirty seconds. An unlabelled heap does not.
- Photograph the room as a whole before touching anything in it.
- Photograph each significant item individually, in place, with make and model where relevant.
- Move to a staging area and label by room.
- Note anything you cannot photograph — items under standing water, for instance — in writing with the date.
- Keep receipts for anything you buy to manage the situation: gloves, bags, tarps, storage.
A word on personal protective equipment
If you are handling flood-contacted contents yourself, treat it as contaminated work rather than tidying up. Waterproof gloves, closed footwear you are willing to discard, and eye protection if you are moving anything overhead.
Wash thoroughly afterwards, and keep children and pets away from both the affected area and the staging piles. Anyone in the household who is pregnant, immunocompromised or has a respiratory condition should stay out of it entirely — that is not caution for its own sake, it is the standard advice for Category 3 exposure.
Frequently asked
Can I bleach flood-damaged carpet and keep it?
No. Bleach does not reliably penetrate the full thickness of carpet and pad, and the contamination is throughout the material rather than on its surface. Pad goes in every case; carpet face after true flood water goes too.
It was only rainwater. Is that really contaminated?
Rain is clean until it lands. Once it has crossed a roof, a yard, a patio or a street, it carries soil organisms, animal waste, landscape chemicals and debris. Category is determined by what the water has contacted, not by where it started.
Do I have to keep everything until the adjuster comes?
Ideally yes, and certainly the photographs. Where health risk makes storage genuinely unsafe, document thoroughly and get written agreement to dispose. Never discard on a verbal assurance alone.
Expert insight
Photograph before you discard
The most expensive mistake we see after a flood is disposal before documentation. Contents claims are settled from evidence, and a bag at the kerb is not evidence. Photograph each item where it sits, note what it was and roughly what it cost, and only then remove it. It adds an hour to a bad day and it is routinely the difference of thousands on the contents side of a claim.
The bottom line
Porous and flood-contacted means discard. Hard and non-porous means clean and disinfect. Everything in between is worth a professional assessment before it goes in a skip.
Photograph first, always. We document contents as part of the job and provide the record to your carrier alongside the structural scope.
