In Brooklyn's brownstones and multi-family buildings, a hidden leak isn't just your problem — it can travel through plaster walls and floors and show up as damage on a different level, creating stress with neighbors or landlords. Rather than guessing or cutting into walls to search, our technicians use acoustic listening equipment, thermal imaging, and moisture meters to pinpoint the exact source of the leak first.
This non-invasive approach means less damage to older plaster and lath walls common in Brooklyn brownstones, and faster answers for insurance claims or landlord/tenant disputes. Once the leak is located, we'll walk you through exactly what repair is needed and provide a flat-rate quote before any work begins.
