What We Do
A stain on a fourth-floor ceiling is rarely coming from directly above it. Water travels along framing, ducts, and pipe chases before it appears, which is why guess-and-patch repairs so often fail. We use systematic controlled water testing — isolating one variable at a time — to find the true entry point before anyone opens a wall.
Controlled water testing is the only reliable exterior leak diagnosis method: start at the lowest suspected entry point, test one element in isolation, and work upward until the leak reproduces. It takes patience, and it is the difference between one correct repair and four wrong ones. For active emergencies — a storm-opened roof, a failed parapet, water coming into an occupied unit — we stabilize first with temporary protection to stop the damage, then diagnose properly and price the permanent repair. Our crews are on call for emergency response across the five boroughs and Westchester, and we document every stage with photographs for your insurer or managing agent.

Our Step-by-Step Process
Clear and stress-free from first call to final sign-off.
Stabilize the Active Leak
If water is actively entering we stop it first — temporary membrane, tarping, or sealing — so the damage stops accruing while we diagnose.
Interior & Exterior Survey
We document where water appears inside, then inspect every exterior element above and around it, building a ranked list of suspected entry points.
Controlled Water Testing
We test one element at a time from the lowest suspect upward, isolating variables until the leak reproduces and the entry point is confirmed, not guessed.
Permanent Repair & Retest
We repair the confirmed entry point, then repeat the water test on that element to prove the leak is closed before we call it done.
