New York, NY Leak Detection & Consulting
Finding the True Source of Water Intrusion in New York City Buildings
Building Envelope Leak Detection in New York, NY
In a New York City high-rise, the stain on the ceiling is rarely where the water got in. Wind-driven rain can slip past a worn window seal on the twentieth floor and travel down inside the wall, appearing in an apartment or office several floors below. Water through a failed terrace membrane or setback flashing can follow slab edges and pipes before it drips, and leaks from shared walls and parapets often show up next door. Patching the visible damage rarely solves the problem and leads to repeat repairs and frustrated residents and tenants. Presto Restoration uses controlled testing and careful inspection to show exactly where water enters, bringing more than 25 years of experience to towers, co-ops and condos, hospitals, universities and historic buildings. In New York City, our goal is to fix the cause once.
OUR DIAGNOSTIC METHODS FOR NEW YORK CITY BUILDINGS
We pick the tests that answer the questions your New York building is raising and skip the ones that would not change the repair.
Controlled water testing recreates a leak on our schedule. We wet one small area at a time while a technician watches inside, so the failed component is identified without waiting for the next storm.
Infrared thermography shows temperature differences that reveal wet materials and air leaks, especially on cold days.
Moisture meter readings map how far water has spread, and repeat readings confirm whether repaired areas are drying.
Where permitted, drones let us inspect upper facades, setbacks and rooftop equipment, revealing cracked sealant, open joints and loose flashing. Elsewhere we use rope access and swing stages for a close look.
When needed, we make small controlled openings to see flashings, insulation and framing directly, then close and seal them.
Each investigation is sized to the problem, from one leaking terrace door to recurring leaks across a tower, and we explain why each method is included.

New York City Leak Detection & Consulting FAQs
Does Presto offer leak detection as a standalone service in New York City?
No. Our leak investigations are part of larger commercial restoration projects, which typically start at $50,000. For an inspection report alone, a specialty engineering firm is the better fit.
What methods does Presto use to find leaks in New York City buildings?
Controlled water testing, infrared thermography, moisture mapping, drone or rope access inspection and, when needed, small investigation openings.
Why does diagnostic work matter before restoration?
Fixing the wrong component wastes money and leaves the leak in place. Confirming the entry point first makes the restoration last.
Does Presto provide expert witness or litigation support?
No. Presto does not provide forensic engineering, expert witness testimony or litigation support, and we recommend a specialty forensic engineering firm for that work.
What does a diagnostic report include?
Photo-documented findings, confirmed entry points, testing results and a prioritized repair scope for your building.
How long does diagnostic work take?
A day or two for one problem area, or a couple of weeks for a full study of a large building. Water testing needs above-freezing temperatures.
