Water and crawl spaces
Crawl space drainage and sump systems
Tier B · 26 towns covered
Interior perimeter drainage and a pump to move groundwater away before it reaches the space under your floor.
Homeowners here run into this regularly, and the fix depends heavily on what's actually causing it.
What people notice first
- Water sitting on the ground under the house after a storm
- A tide line or silt mark along the base of the foundation wall
- A pump that runs constantly, or one that has stopped running at all
- Ground that never fully dries out between rains
What a contractor will do
The usual approach is a perimeter drain below the level of the crawl floor feeding a pump, sized to the volume of water actually arriving. Where the pump discharges matters as much as the pump itself.
$5,000 – $12,000 — typical range, not a quote. What your home needs can only be settled by a registered contractor who comes out and looks at it.

Towns we cover for this
Only the areas where this work actually applies.
Inland mainland
Flat sandy tracts with a high water table. Crawl spaces and slab are the common foundation types here.
Bayfront and lagoon
Dredge-and-fill lagoon communities at low elevation with tidal influence on groundwater.
Long Beach Island
Salt air, timber and concrete pilings, and housing stock split sharply between pre- and post-Sandy.
