After the drying

Mold Inspection & Testing in O'Fallon, MO

An independent assessor confirms whether the assembly that got wet is actually dry, whether growth started while it was not, and how far it reaches. An inspection after a water loss confirms whether the assembly that got wet is dry now and whether growth started while it was not. Readings are taken in the material, cavities are opened where the readings point, and the result is a written scope of what is dry, what is not, and what has to be corrected for the repair to hold.

The pro who inspects is the pro who quotes

On this site, inspection is the last check of a water job rather than the start of a separate one. Most people reach this page because something was wet, was dried, and a smell or a stain came back. The inspection answers whether the material is dry now and whether anything grew while it was not. Nothing here is medical advice; questions about health are for a clinician.

Often needed alongside

  • Mold Remediation

    Growth and the material it grew into come out under containment, what remains is cleaned, and the assembly is dried and read before anything closes it in.

  • Structural Drying & Dehumidification

    Sealed air movers and dehumidifiers bring framing, subfloor and drywall back to a measured dry standard, with daily readings logged from inside the material.

Frequently asked questions

Why is the ductwork inside the floor?

Because the trusses are deep enough to hold it. Open-web floor trusses leave a clear space through the middle of the floor structure, so the heating and cooling runs go inside it rather than below, which keeps the basement ceiling flat. It also means the duct and the framing share a cavity.

Can the system be used during the drying?

Not while there is water in the floor, and that is the practical difficulty. Running air through a duct that sits in a wet cavity moves that moisture to every room the system serves. The house is carried on portable equipment until the floor has come down and the duct has been checked.

How far does the wet area go?

Along the trusses rather than across the room. The open webs let water run the length of a truss and through into the next, so a failure at one point produces a wet run following the framing. The ceiling below is opened along that line rather than beneath the visible damage.
