Illustrative case: a flooded 1960s basement with tile over black adhesive

The situation

Illustrative example. Not a real job or customer.

A homeowner in a 1960s ranch in the west metro wakes to find an inch of water across the finished basement. The water heater tank has split. The basement floor is dark-green nine-inch tile, several squares are already lifting, and black adhesive is visible where one has popped loose. A water mitigation provider is on the way.

1. The owner shuts off water to the heater and turns off its gas supply at the appliance valve, staying clear of the wet area near the electrical panel.
2. When the mitigation technicians arrive, the owner tells them the house was built in the 1960s and asks them not to pull up any tile yet.
3. The technicians extract standing water and set up dehumidification, positioning air movers so they do not blow across the broken tiles.
4. The owner calls two CDPHE-certified building inspectors, picks the one who can sample that day, and verifies the certification with CDPHE.
5. The inspector samples the tile and the adhesive separately, plus the drywall where the mitigation provider wants to make flood cuts.
6. Results show the tile negative and the adhesive positive. The drywall joint compound is negative.
7. Flood cuts on the walls proceed right away. The owner hires a certified abatement contractor to remove tile and adhesive under containment.

Drying of the walls continued with only a short pause, the floor was removed under controls, and clearance was completed before new flooring went in. The owner's claim file included the inspection report, the abatement scope, clearance results and the waste record.
