What a licensed remediation job actually involves, in the order it happens. Every step below is the contractor's work, not ours.
-
Step 1: Assessment
A licensed assessor establishes whether there is growth, how far it extends, and where the moisture is coming from.
-
Step 2: Containment
Barriers and negative air pressure go up first, so disturbing material does not move spores into clean rooms.
-
Step 3: Removal
Porous material that cannot be cleaned comes out - drywall cut past the moisture line, insulation, carpet pad, cabinet bases.
-
Step 4: Drying
Dehumidifiers and air movers bring the structure back to a dry standard, with readings logged from the material rather than the surface.
What drives moisture problems in Derry
The Derry area our local pros cover for mold removal takes in East Derry Historic District. Beaver Brook still powers the mill story, and October's 4.86 inches is the last big input before granite till locks, so a 1982-median town takes its wettest month into freeze-up.
Housing stock
Of roughly 9,904 housing units, about 7,436 were finished in 1989 or earlier, which puts the median construction year at 1982. New England frame on full basements, median 1982, on granite till and outwash along Beaver Brook, with mill-era stock near the ponds and later tract on the drumlins.
Climate and water risk
October alone accounts for 10.4 percent of the 46.68 inches this area sees in an average year, on 1991–2020 normals recorded 4.4 miles away at W HAMPSTEAD. October's 4.86 inches lands on till that is about to freeze. Water that month puts in the soil is still there when the ground locks, and frost then pries foundation joints around that moisture until spring. The mill ponds hold a water table under the oldest blocks the whole time.
Common moisture and mold problems in Derry
- October rain saturating granite till that then freezes in place against basement walls
- Beaver Brook mill ponds holding a water table under the oldest blocks through winter
- Drumlins shedding melt in a short spring onto the next downhill foundation
- 1982-median frost walls with original damp-proofing that freeze-thaw has already split

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.
