What comes out after a flood
The removal list is decided by porosity and by the flood line. Drywall is cut back to a clean edge above the highest reading, not above the visible line, because the paper face wicks water upward well past where the mark stops. The insulation behind it comes out with it. Carpet and pad go. Particle board and medium density fiberboard swell and lose strength and do not come back.
Contents follow the same rule. Upholstered furniture, mattresses, cardboard, paper, books and anything with a porous surface that sat in flood water are not salvaged. Hard plastic, metal, glass, sealed goods and solid wood furniture with an intact finish are cleaned and kept. Where an item has real value, sentimental or financial, it gets an assessment rather than an automatic answer, and you are told plainly what the risk is.
Everything removed is photographed in place first, measured and logged against the category that required it. In a flood that list is long, and a long list without a record behind it is the thing an adjuster will not accept.
Cleaning comes before drying
In a clean water loss the sequence is extract, then dry. In a category 3 loss there is a step in between, and skipping it is the most common way a flood job goes wrong. Silt and residue settle onto every horizontal surface as the water drops, and running air movers over that residue puts it into the air of the building and into every room the air reaches.
So the order is extraction, then removal of the porous material, then cleaning and treatment of the remaining structure, and only then drying equipment. Surfaces are cleaned physically instead of being sprayed and left, because an antimicrobial applied over silt treats the silt rather than the surface under it.
Where the flood reached ductwork or an air handler, the system is not run until it has been dealt with, because an HVAC system that took flood water distributes what is in it to every room in the building the moment it is switched on.
Drying a building that took surface water
What is left after a flood removal is mostly framing, masonry and slab, and all three release water slowly. Concrete and block are class 4 materials and they hold water in their surface layer for a long time, so the drying plan uses dehumidification with the capacity to hold a dry enough condition in the space along with heat, because a cold masonry surface releases almost nothing.
Framing lumber usually survives, and it is read individually rather than assessed by eye. A bottom plate sitting on a wet slab is the last thing in the assembly to reach the dry standard and it is one of the fixed monitoring points for that reason. Nothing is rebuilt over it until it reads.
The timeline follows from the material rather than from a promise. A lower level stripped back to framing and masonry is drying dense material that gives water up slowly, and the daily log is what tells you where it stands.
The flood insurance line, stated plainly
Flood is excluded from almost every standard homeowners policy. It is covered separately under a National Flood Insurance Program policy, and a homeowner who does not carry one generally has no cover for a flood loss, whatever their homeowners policy pays for other kinds of water.
That distinction catches people out because the water on the floor looks identical. A river that came up into a basement and a supply line that burst in the same basement produce the same puddle and two entirely different insurance conversations. It is worth knowing which policy you hold before the weather makes it urgent.
The loss is documented the same way in either case: photographs from before anything moved, the flood line recorded, a category and class assignment, an inventory of removals with the reason for each, and a daily reading log through the drying, so you have a complete file to give your insurer. We do not file, adjust or negotiate the claim.
