Waterproofing
Waterproofing Contractors in NYC & Yonkers
Basement, facade and roof waterproofing that fixes the source — not the symptom.
Water is the most expensive problem a building can have: it rots joists, spalls brick, ruins finishes and invites violations. We trace leaks to their actual source and seal them permanently — instead of painting over the stain and waiting for the next storm.
Our Waterproofing Services
- Basement waterproofing — interior and exterior systems, foundation sealing, drainage correction for NYC's flood-prone blocks
- Facade waterproofing — clear sealers and elastomeric coatings for brick and masonry walls (pairs with repointing)
- Roof & parapet waterproofing — coatings, flashing and coping repairs that stop top-down leaks (see parapet inspections)
- Balcony & terrace waterproofing — membranes under tile and pavers
- Below-grade brownstone waterproofing — for Brooklyn's garden-level apartments
Honest Diagnosis First
Not every leak needs a full system. We inspect free of charge, show you where the water actually enters, and quote in writing only what's needed — response within 24 hours.
