Testing & Assessment
Mold Inspection & Testing in Derry, NH
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
October rain and then a freeze. Which one actually opens the foundation?
The pair. October puts the water in. Frost pries the joint around it. A dry freeze is much less destructive than a wet one, which is why an October peak is a worse local month than a heavier summer cell would be. The rain is the load. The freeze is the wedge.
The mill pond is picturesque. Is it also the water table?
For the blocks along Beaver Brook, yes. The ponds were built to hold water, and they still do. A cellar on that corridor can wet from below in a dry week because the pond, not the last storm, is setting the table. Picturesque is not drained.
A 1982 house on a drumlin. Did they build above the problem?
Above the pond. Not above freeze-thaw. Drumlin till still takes October rain and still locks, and the downhill side of that lot sheds melt onto the wall in April. You have left the mill hydrology and kept New Hampshire's winter. That is a different wet wall, not a dry one.
