Testing & Assessment
Mold Inspection & Testing in Nashua, 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
The mill closed decades ago. Why would a raceway still wet a cellar?
Because the channel is still there. Raceways and tailraces were cut below street grade and were never filled to a modern dry standard, so they remain a permanent water table against the cellars that were built next to them. A dry mill does not mean a dry race.
Water showed up two floors down from the roof stain. How?
In a triple-decker the party wall and the stair chase are continuous. Water runs along those paths and exits wherever the finish is weakest, often a floor or two below and an address to the side. The stain marks the exit, not the entry.
October is not winter. Why does that month decide what the cellar does until April?
Because the ground is still open in October and locked by November. Rain that soaks in during the peak has no chance to drain once frost takes the soil, so a wet October is a wet cellar through the whole freeze. The winter total matters less than whether the soil went into winter already loaded.
