Building Leak Investigation in New York City
Fixed-fee leak investigations for NYC property managers, owners, and boards. We inspect likely water paths, document visible conditions, and give you clear next steps before another patch repair.
Stop Guessing Where the Water Is Coming From
Water infiltration rarely follows a straight path. A ceiling stain may be connected to failed sealant, open masonry joints, a parapet condition, roof-edge flashing, or a window perimeter several feet away from the visible damage.
Repeated patch repairs get expensive when the source is not documented first. ARCONDES investigates the likely water path, photographs relevant conditions, and prepares practical findings for managers, owners, boards, and contractors.
The goal is simple: identify the most likely contributing conditions, document what is visible, and define the next repair step with less guesswork.
A leak investigation is appropriate when:
- Water is entering through walls, ceilings, windows, or facade openings
- The same leak returns after prior patch repairs
- Tenants are reporting active or recurring water intrusion
- A contractor has proposed repairs but the source is still unclear
- The board or manager needs documentation before approving work
- Insurance, DOB, or repair planning requires clearer evidence

Common Leak Sources in NYC Buildings
Open Masonry Joints
Wind-driven rain can enter through deteriorated mortar joints and travel through wall assemblies before appearing indoors.
Failed Window Sealant
Aging caulk and perimeter joints around windows are common entry points during heavy rain.
Parapet and Coping Conditions
Cracked parapets, failed coping joints, and roof-edge conditions can send water into the wall from above.
Flashing and Roof-Edge Failures
Damaged flashing at transitions can direct water behind the building envelope.
Facade Cracks and Displacement
Cracked masonry, movement, or displaced units can create openings that worsen over time.
Prior Repairs Without Diagnosis
Patch repairs may hide symptoms without addressing the actual water path.
