Testing & Assessment
Mold Inspection & Testing in Rochester, 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 damage shows in March. Did something happen in March?
Because the water never left. Ground saturating in autumn freezes with that moisture in place, and each thaw cycle works cracks and joints wider through the winter. By the March melt, the openings are larger than they were in the fall and there is a great deal of water available.
Are ice dams caused by the roof or by something else?
Almost always insulation, showing up as a roofing symptom. Heat escaping into the attic melts snow on the upper roof, the meltwater refreezes at the cold eave, and the ridge that forms backs water under the covering. Replacing the surface without addressing heat loss reproduces the dam.
This was a mill town. Does that affect the older housing?
That it moves moisture rather than blocking it. Brick and lime mortar of that period transport water by design, and no damp-proof course was installed. Managing what reaches the outside of the wall, and the humidity inside it, is more productive than trying to make the wall itself a barrier.
