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.
What usually prompts the call
- 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 a contractor will do
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.

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.
