Groundwater & Basement Water Intrusion in Derry, NH
Basement seepage, failed sumps and water through the slab are extracted and dried, and the path from the ground is found so the floor stays dry next season. The path from the ground is named first: through the wall, up through the slab, back through a drain, or from a sump that stopped. The space is extracted and dried, with the porous materials the water touched removed, and the delivery is addressed, because a dried floor only stays dry if the water stops arriving.

Often needed alongside
- Structural Drying & Dehumidification
Sealed air movers and dehumidifiers bring framing, subfloor and drywall back to a measured dry standard, with daily readings logged from inside the material.
- Emergency Water Extraction
Standing water is pumped and extracted around the clock, before it climbs the walls and soaks the subfloor. Same-day response where coverage allows.
- Mold Inspection & Testing
An independent assessor confirms whether the assembly that got wet is actually dry, whether growth started while it was not, and how far it reaches.
Frequently asked questions
What does green framing do to a house?
It shrinks across the grain as it dries, which pulls the structure slightly out of shape. Studs and plates lose a fraction of their depth, nails back out, and the gaps that open are at the joints between members. None of it is dangerous; all of it gives water and air a path.
Where does that matter in a loss?
In how far water travels. A tight wall holds a leak roughly where it started; one with open paths at the top and bottom plates lets it run into the floor structure and along it. Contractors here expect the wet area to be wider than the failure suggests, and meter accordingly.
Does it explain other things owners notice?
Frequently, yes. Nail pops in ceilings, trim that has opened at the corners, and drafts at outlets in exterior walls all come from the same source. They arrived in the first few years and then stopped, which is the pattern that distinguishes drying shrinkage from anything currently going wrong.
