Structural Drying & Dehumidification in Concord, NH
Commercial dehumidifiers and air movers remove moisture from the structure, with daily readings logged from the material itself for claim documentation. 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
The sand plain the city sits on is a very good aquifer.
It is, and coarse sand passes water sideways with very little resistance, so a rise in the river becomes a rise underfoot a long way from the bank with nothing arriving over the ground. That is why some cellars here fill on a schedule that matches the gauge rather than the rainfall, and why grading does not touch it.
Two weeks of thaw and the ground frozen underneath it.
Nearly always. A whole season of snow comes away over roughly two weeks onto ground closed to a depth that will accept none of it, so every bit of the volume travels at the surface. Rain during that fortnight adds rather than substitutes. By the end of March what counts is a working pump and an outlet not frozen shut.
Cracks open in the cellar wall every spring.
Frost accounts for nearly all of it on walls of this age. Moisture in the soil alongside freezes, expands and presses inward, and the wall yields slightly where it can without fully recovering in the thaw. The change therefore turns up in March rather than during any storm. Drier ground going into the freeze does more than any repair in spring.
