Structural Drying & Dehumidification in Derry, 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 ground is ledge. Should that not mean dry?
Rock supports a structure admirably and takes in virtually nothing. Rainfall either remains on the surface or discovers a seam and runs along it, so rather than dispersing through soil it surfaces in a concentrated stream somewhere below. A property on stone therefore encounters more water at the footing, not less. Firm and dry are separate matters entirely.
There are old ponds above the house. Should that worry anyone?
Old mill ponds and their structures are scattered across this part of the state, many with no traceable owner because the companies that built them are long gone. The state register of dams records what exists and who holds it. Where a structure above a property is deteriorating, that register is the right place to start.
The town grew very fast in one stretch of decades.
It did, from a small town to one of the largest in the state, and a great deal of the housing arrived in that window on ground that had been farm and woodland. The channels receiving what it sheds were sized for the earlier condition and extended piecemeal, which is why upstream capacity is usually the constraint.
