Groundwater & Basement Water Intrusion in Trenton, NJ
Basement seepage, failed sumps, and hydrostatic pressure against the foundation are extracted and dried, and the path from the ground is identified so the loss does not repeat. Groundwater and basement seepage are extracted and dried only after the path from the soil is identified — a wall, a slab, a drain, or a failed sump. Drying the interior without stopping that path returns the same water to the same floor.
Frequently asked questions
Our part of the river seems to behave differently from downstream.
It does, and the fall line is why. Below it the river is tidal and its level answers partly to the sea; above it, to flow arriving from upstream. That transition runs through this city, so two properties a mile apart along the water can face genuinely different mechanisms. Establishing which reach you are on determines whether the tide is worth watching alongside the forecast.
The neighbor will not dry their side of our shared wall.
That is the hardest practical problem in rowhouse drying and worth escalating early. A party wall wet from both sides will not dry from one, and equipment on your side alone pulls moisture through from theirs indefinitely. Get the readings on the shared assembly recorded, put the access request in writing, and tell the insurer the wall is wet from both faces. That record carries any later conversation about cost.
It backed up out of a fixture rather than seeping in.
In the older neighborhoods that is the combined sewer rather than your plumbing. One pipe carries sanitary and storm flow and, when it surcharges, relieves through the lowest connected opening. A backwater valve on the building sewer is the standard remedy, and it must stay accessible and be inspected, because one that has silted open provides nothing when it is needed.
