Testing & Assessment
Mold Inspection & Testing in Marshalltown, IA
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
North Dakota has a Jamestown on till too. Is this the same June problem?
No. That prairie city sees about 3.6 inches in June on a 21-inch year. This packing town takes 5.7 inches on a 36-inch year, on an Iowa River industrial trench, 1958 stock. Shared till word; different river, different load, different grid. Do not copy a James River playbook onto a Marshall County cellar.
The packing plants closed. Why do the alleys still wet basements?
The grid remains. Alleys were laid to serve the plants, not to drain 5.7 inches of June rain off till. Closing a plant did not retile the lots or deepen the Iowa. The water still uses those alleys as the path to the 1958 floor drains.
Hays, Kansas, also sits on a slight grade. Same perched-till story?
Hays is shortgrass loess and a 25-inch year. This is a wetter Iowa till plain with a packing-plant sewer system. The word till is shared; the June total and the industrial drains are not. Ask how the water entered the cellar before assuming a High Plains seepage job.
