Category asks what’s in the water. Class asks how much of the structure it soaked, and that answer sets the equipment count, the drying timeline, and the bill.
Part of one room, little or no wet carpet. A few air movers and a fast, monitored dry.
A full room: carpet and pad soaked, walls wicked under about two feet. The most common class.
Overhead loss: ceilings, insulation, walls, and floors wet at once. The most water a structure can hold.
Hardwood, plaster, masonry, concrete. Deep-held moisture that releases slowly and needs specialty drying.
Class measures evaporation load: how much water the structure absorbed and how hard it will fight to keep it. It answers a different question than category, which grades contamination. Every job gets both labels, and both drive your scope: category sets the safety rules, class sets the equipment math.

No pressure, no truck rolled, just an honest read on your situation.
The wet footprint is a strip or corner: some floor, the bottom of one wall, minimal carpet. Mostly low-porosity materials.
Spot extraction, targeted air movement, and a short monitored dry. Demolition is rarely needed at all.
A handful of air movers, one LGR dehumidifier, moisture meters to verify dry standard before the equipment leaves.
Lowest risk, but water travels: check under baseboards and inside wall bottoms. Small jobs sometimes land under your deductible, and we tell you plainly when paying cash beats filing.
An entire room is affected: carpet and pad soaked, drywall wicked up to about 24 inches, readings elevated across the space.
Full extraction, pad pulled where saturated, perimeter and cavity airflow, then daily readings until every material verifies dry.
Air movers placed to the room’s geometry, LGR dehumidifiers sized to the cubic footage, thermal imaging plus meters for the daily log.
The 48-hour mold clock is the main enemy; contents need blocking or moving. Expect several monitored drying days, not one loud afternoon.
The loss came from above, an upstairs failure or roof entry, so ceilings, insulation, walls, and floors are wet together.
Controlled removal of what cannot dry (soaked insulation, sagging ceiling drywall), zoned structural drying, and often a contents pack-out.
High-capacity dehumidification, large air-mover counts, cavity-drying systems, and containment to manage humidity zone by zone.
Treat sagging ceilings as a collapse hazard and assume wet ceilings mean wet wiring. Displacement is possible; this is where ALE coverage earns its keep.
The dense materials are wet: cupping hardwood, plaster, brick, slab, crawl-space framing. Surfaces can read dry while deep probes disagree.
Specialty systems on a longer, daily-verified timeline: floor-mat drying, cavity injection, applied heat, sometimes desiccant dehumidification.
Rescue-mat floor systems, desiccant dehumidifiers, heat-drying rigs, and deep-probe meters that read where the water actually is.
The twin temptations are demolishing what could be saved and quitting while the slab is still wet. Patience plus documented deep readings protects both the floor and the claim.

No pressure, no truck rolled, just an honest read on your situation.
Five-minute callback, honest advice, zero obligation. That’s the whole pitch.
Keep your phone nearby. If water is still spreading, shut off the main valve now, it’s usually in the basement or crawl space, on the street-facing wall.
