Basement Waterproofing · Princeton, NJ
We diagnose water entry causes and install drainage, sump, and seals tailored to Princeton basements.
We address common local issues like high water table, spring runoff, and freeze-thaw cracks using interior and exterior drainage techniques and moisture controls. Work is sized to the foundation type and finished basement conditions to limit indoor humidity and mold risk.
Our work
FAQ
Costs vary with access, foundation type, and chosen method; small interior drains start lower while exterior excavation and full systems cost more, so expect a site-specific estimate after inspection.
Interior drain and sump installations often take 2–4 days; exterior excavation can take several days to a week depending on soil, weather, and restoration needs.
We inspect walls, floors, grading, gutters, and take moisture readings, then show you problem areas and present practical repair options with a written scope.
Most interior drain and sump installations allow occupants to remain with limited access restrictions, while exterior excavation may require short periods of entry restriction near work areas and noise.
Maintain gutters and downspouts, check grading away from the foundation, and run the installed sump pump system as recommended to keep groundwater managed.
