Basement Waterproofing · New Providence, NJ
Interior basement waterproofing focused on stopping leaks, managing moisture, and keeping finished basements usable. We evaluate conditions, recommend fixes, and provide a clear estimate.
We address water entry inside the foundation and slab: perimeter drainage, interior sump and pump systems, crack sealing, vapor barriers, and dehumidification for finished basements. Every scope starts with a site assessment to locate sources—exterior causes are noted only insofar as they affect interior waterproofing and recommendations.

FAQ
Costs vary by scope: simple crack sealing and interior drainage can be lower-cost, while full perimeter drainage with a sump pump and finished basement repairs is higher. We provide a free walkthrough and written estimate after inspection to give an accurate price.
Most interior waterproofing installs run 2–7 days depending on extent. You may have restricted access while we work and should avoid stored items in the work area; we protect remaining finishes and communicate a daily plan.
We start with diagnostics, recommend interior drainage, sump and pump, crack repair, and moisture control options. We don’t promise outcomes we can’t verify; after installation we test systems and document moisture readings so you have a clear record.
Sometimes partial removal of base trim, drywall or flooring is necessary to access the foundation. We note required removals in the estimate and include restoration options so you know the repair scope before work begins.
Schedule a walkthrough and estimate—our consult includes a moisture inspection and written proposal. Contact us to book a time for a site visit so we can assess your basement waterproofing needs in New Providence.
