Water and crawl spaces
Foundation crack and seepage repair
Tier A · 26 towns covered
Injection and sealing for cracks in poured walls and block that let water through during heavy rain.
Homeowners here run into this regularly, and the fix depends heavily on what's actually causing it.
The things people ring up about
- A crack that weeps only during heavy rain
- White mineral staining running down the wall below a crack
- A crack that has visibly widened since you first noticed it
- Damp patches on one specific spot of the wall
What the work involves
Injection seals the crack against water. It does not address why the wall cracked. A contractor should tell you which of the two you are dealing with, because a moving crack will simply open again.
$400 – $1,500 per crack — typical range, not a quote. What your home needs can only be settled by a registered contractor who comes out and looks at it.

Where we can route this
The ground differs across the county, so this doesn't apply everywhere.
Inland mainland
Inland mainland lots on sand, where groundwater sits close enough to the surface to matter under a floor.
Bayfront and lagoon
Lagoon communities built on fill, where the water beneath a house answers to the tide as much as the weather.
Long Beach Island
The barrier island — salt air, sand, and older cottages still sitting on crawl spaces and slab.
