Structural Drying & Dehumidification in Derry, NH
Commercial air movers and low-grain refrigerant dehumidifiers pull moisture out of the structure, with daily moisture-meter readings logged for your insurer. Structural drying brings building materials back to a documented dry standard using air movers and dehumidifiers rather than surface evaporation alone. Moisture readings are logged through the process so the substrate, not just the surface, is confirmed dry before anything is rebuilt.

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.
