Testing & Assessment
Mold Inspection & Testing in Alton, IL
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
Melvin Price is a lock, not a distant levee. What does a May pool do to a cellar on the flats?
It sets the table for miles. When May's 5.46 inches add to a pool that cannot drop, the extra goes into fill and cellars rather than downriver. A calm lock is a full Mississippi against the terrace, not a dry basement. The dam is the hydrology; the rain is only the increment.
Cave-mouth streets sit in the limestone. Is that the same May job as a lock-pool house?
No. The bluff fails from limestone seepage and from downspouts that terminate at the cut. The flats fail from a river the lock will not let fall. Treating both as one Mississippi story misses the cave-and-cut problem on one and the pool problem on the other.
Belleville's story is Illinois Basin coal. Does a void explain an Alton cellar?
Not as the first diagnosis. This town is a lock-and-bluff town. Coal country sits inland. A wet cellar on Leverett Place is pool and limestone, not a mine trough, and following a Metro East coal map to the river will miss the dam that is actually holding the water.
