Testing & Assessment
Mold Inspection & Testing in Pierre, SD
An assessment establishes whether mold is present, where it is growing, and how far it extends — before anyone quotes removal. A mold inspection locates moisture and growth that a room-level look would miss, reading wall cavities, subfloor, and the areas behind finished surfaces. The result is a scope: what is affected, what has to come out, and what is driving the moisture.
Most people reach this page after noticing something rather than after something broke: a smell that returns, a stain that spreads, a room that feels damp. An inspection answers what is actually there and where the moisture comes from, which is the information every later decision depends on. Several states, Texas among them, keep assessment and remediation as separate licensed roles specifically so the party identifying the problem is not the party selling the fix. Nothing here is medical advice — if you have health questions, those are for a clinician.

Frequently asked questions
The house is well above the Missouri. Does Oahe still matter?
For inundation, only on the lowest terraces. For the shale, the reservoir is a separate story: it holds a water table against those terraces on a managed schedule. Up the hill the problem is the shale itself, which moves with small wettings whether the river is high or not.
Why is this clay called gumbo, and what does that do to a drain?
It is a fat, sticky shale residue that swells when wet and smears when worked. Original exterior drains laid in it clog with the same material they were meant to carry, often within a few years. A 1976 basement here is frequently sitting with a drain that has not functioned for decades.
The wall cracks in June and again in January. Two problems?
One soil, two seasons. Shale swells with the June wetting and heaves with the winter freeze, so the same joints are worked twice. A crack that is blamed on frost often opened first in a wet June and only became obvious when the ground locked.
