Testing & Assessment
Mold Inspection & Testing in St. Louis, MO
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
Water came up through the floor drain rather than in at a wall. What does that mean?
That the public sewer surcharged rather than the foundation leaking. Water arriving through a fixture during heavy rain is Category 3 and carries sewage, so the scope is disinfection and porous material removal rather than exterior drainage. The two failures look identical on the floor and are not related.
The house is from the 1920s. Is a dry basement realistic?
Managed, yes; sealed, no. Brick foundations of that period were built to carry load, not to exclude moisture, and the damp-proofing layers taken for granted now did not exist. Controlling surface water and keeping the perimeter drained accomplishes far more than treating the inside face of the wall.
Does a backwater valve solve sewer backup?
It addresses the specific failure of water entering backward through the lateral, which is the mechanism here. It does nothing about groundwater or surface water, so it is worth understanding which problem a given basement actually has before installing one and assuming the question is closed.
