Basement Waterproofing · Cranford, NJ
Interior waterproofing and drainage fixes for finished and unfinished basements. We focus on practical repairs that stop leaks, control humidity, and protect living space.
We address water entry, basement wall seepage, and standing water through interior solutions: perimeter drains, sump pump installs, interior French drains, wall sealing, and controlled dehumidification. Work is scoped for basements being finished, used for storage, or converted to living areas.

FAQ
Cost depends on cause and scope. Simple wall sealing or a dehumidifier runs lower, while interior perimeter drains and a sump system cost more. We provide a no-obligation estimate after an on-site assessment to show exact materials and labor.
Most interior waterproofing jobs take 2–7 days: inspection, trenching for a perimeter drain, sump install, and finish repairs. Expect noise and dust during excavation; we protect floors, set up dust barriers, and keep a clear work path so homeowners can use other areas.
Sometimes a narrow trench along the perimeter requires removing baseboard and flooring edge. We limit demolition to the minimum needed, document existing finishes, and include restore work in the estimate.
We test the system, advise on dehumidifier set points, and show where to check sump operation. Routine checks of the pump, discharge line, and interior humidity keep the system working.
Yes. Schedule a walkthrough so we can inspect moisture sources, take measurements, and provide a written estimate. The onsite consultation is the next step to get an accurate quote and timeline.
