Groundwater & Basement Water Intrusion in Dover, 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
Why is this assembly more trouble than a plain door?
Because it has more joints and a wider opening. Each sidelight is a separate unit fitted into the same frame, so there are vertical joints at every panel and a horizontal one over the top. All of them rely on the original detailing and on a sealant that has usually been renewed rather than replaced.
Where does the water actually appear?
At the bottom of a sidelight, on the floor just inside, or in the basement directly below the entry. Water entering at the head or the jambs runs down inside the frame and reaches the sill, which sits on the floor structure. Staining on the ceiling below an entry hall is a common way it is first found.
What is worth checking each autumn?
The joints between the sidelights and the door frame, and the sill under the whole assembly. Both are reachable and both take a minute to look at. A soft spot at the bottom corner of a sidelight means the framing behind it has been wet for a while, and that is a repair worth doing before winter rather than after.
