Brooklyn water damage & leak restoration

Brownstones, limestones and multifamily walk-ups share party walls, risers and roofs, so one leak can reach several units and neighbors. Blue Arrow serves Park Slope, Sunset Park, Bay Ridge, Bensonhurst, Dyker Heights, Sheepshead Bay and the rest of Brooklyn with 24/7 drying, sewage cleanup and flat roof leak repair.

How Brooklyn buildings fail

  • Flat roofs and parapets: most row houses have flat roofs with parapet walls, scuppers and drains that clog; leaks show up on top-floor ceilings and along party walls. See roof leak repair.
  • Aging risers and cast-iron stacks: century-old plumbing leaks inside walls between floors. See pipe leak repair.
  • Garden-level and cellar flooding: heavy rain overwhelms yard drains and the combined sewer. See flood cleanup and sewage cleanup.
  • Plaster and lath: historic walls and ornamental ceilings need careful drying rather than quick tear-out.
  • Boiler and radiator leaks: steam and hot-water heating systems leak at valves and joints.
Historic interiors deserve a gentler approach

Plaster walls, original moldings and parquet floors can often be saved with controlled drying. We map moisture carefully and remove only what can’t be dried, so the character of the house survives the leak.

Brooklyn FAQ

The leak is coming through the party wall from next door. What now?

Notify the neighbor right away and photograph the damage. We can inspect and document the moisture path on your side, which helps both insurers decide responsibility, and start drying your home in the meantime.

Can you work in a landmarked building?

Interior mitigation generally doesn’t require Landmarks approval, but exterior repairs to a landmarked building may. We’ll flag anything that needs a permit before work starts.

24 / 7 Emergency Response

Water, fire and mold don’t wait. Neither do we.

Every hour of standing water raises the cost of the repair. Call the office nearest you — a coordinator answers around the clock, dispatches a crew and can bill your insurance carrier directly.
