Water intrusion inspection on Long Island
A water intrusion inspection establishes where water is entering a building and how far it has spread, before anything is opened. Water travels along framing, down stud bays and across slabs, so the stain marks where it exited rather than where it got in. We image thermally across a broad area, confirm with moisture testing, and where necessary run controlled water testing — then report a likely source and extent.

Coastal exposure changes the problem
On Long Island's South Shore and along the North Shore inlets, wind-driven rain reaches entry points that ordinary rain never touches, and flood history leaves moisture inside assemblies long after the visible damage is repaired.
That is why an intrusion investigation here often finds two distinct things: an active path, and older saturation that was never dried. Distinguishing them matters for both the repair scope and any claim.
- Roofs and parapets
- Exterior walls and cladding
- Windows, doors and thresholds
- Terraces, balconies and decks
- Foundations and below-grade walls
- Mechanical penetrations
Establishing responsibility on evidence
A large share of intrusion investigations exist because two parties disagree — an owner and a contractor, two unit owners, a building and its carrier. Our findings are used in those conversations precisely because we do not stand to win the remediation.
Where the answer turns out to be condensation rather than intrusion, that is the finding, and we say so.
Common questions
Water intrusion inspection on Long Island — answered.
How do you tell intrusion from condensation?
By measuring. Surface temperature is compared against the interior dew point using psychrometric readings taken at the location. If the surface is below dew point, water is forming there rather than arriving from outside — a completely different repair, and one that many facade contractors are not asked to check.
Do you perform water testing?
Where it is appropriate and the building permits it, yes — controlled testing of a specific assembly to reproduce the conditions under which the leak appears. It is particularly useful when a leak only shows up in certain weather.
What do we get at the end?
The likely source, the extent of affected material, thermal and visual documentation, and moisture readings — enough for a contractor to scope the repair or for a carrier to evaluate a claim.
Why us and not a plumber
We write the report. We never bid the repair.
A plumber who finds your leak also sells you the repair. A roofer who inspects your roof also quotes the replacement. That isn't dishonesty — it's structure, and it quietly shapes every finding. We are an independent diagnostic company: we do not perform repairs, we do not sell materials, and we take no referral fee from any contractor. The report is the entire product, so there is nothing for us to gain by finding more than is there.
We can't profit from the work we recommend, because we don't do the work. If your roof is 8% wet, the report says 8% — not "replace the field."
We accept nothing from contractors for sending work their way. Take our findings to your own plumber, roofer, or electrician, or put them out to bid.
Boards, managing agents, and insurance carriers treat an independent finding differently than an estimate from the company that wants the job.
Sometimes the answer is condensation, or a warm duct, or a neighbor's roof. We're paid the same either way, so we say so.
