Facade Leak Investigation

Our facade leak investigation service uses ASTM testing to find the true source of water intrusion—fast, accurate, and non-destructive.

Facade leak investigation is essential when water starts seeping through your building’s exterior walls. These leaks can be hard to trace—but if ignored, they cause mold, corrosion, and expensive damage. Our team identifies the root cause so you can stop the issue for good.

What is Facade Leak Investigation?

This process includes visual checks, ASTM spray testing, and moisture tracking to figure out where water enters the wall. Moreover, we inspect joints, sealants, windows, and penetrations. As a result, you’ll know exactly what needs fixing—without ripping anything open.

Why Investigate Façade Leaks?

  • Find the source of leaks, water stains, and mold
  • Prevent long-term water damage and costly repairs
  • Check how well windows, flashings, and wall systems are working
  • Back up insurance, warranty, or legal claims with real evidence
  • Avoid guesswork—target repairs based on real results

In many cases, a well-executed facade leak investigation saves time, money, and materials—especially in complex buildings.

Our Façade Leak Investigation Services Include:

  • ASTM E1105 water testing (spray rack method)
  • Thermal imaging and moisture detection
  • Window and wall system inspections
  • Sealant and flashing review
  • Repair help and coordination with your contractor

For official water testing standards, visit ASTM E1105.

Common questions

Our leak only happens during storms from one direction. Can you still reproduce it?
Usually, yes. Wind-driven rain leaks are reproduced by combining water application with a pressure difference across the wall, which pushes water through the same defects the storm does. Knowing the wind direction and duration that triggers the leak actually helps us — it narrows which elevation and which joints to test first.
Do you have to cut into the wall to find the leak?
Not always. Interior symptom mapping, exterior survey, scanning and staged water testing are non-destructive and often identify the entry point on their own. We recommend a small exploratory opening only when the mechanism behind the leak is unclear and knowing it would change the repair scope. Openings are coordinated with your contractor and restored.
How is this different from air and water infiltration testing?
Infiltration testing applies a standardized procedure to verify whether an assembly performs to a specified level, often on new or recently installed work. A leak investigation starts from an existing symptom and uses testing diagnostically, isolating one component at a time in a sequence we adjust as findings come in, to prove where water actually enters.
Will you tell us how to fix it, and can you do the repair?
We provide repair recommendations tied to what testing demonstrated, sequenced so you can address the largest contributor first. We can also prepare repair documents and observe the corrective work. We do not perform repairs ourselves — we are consulting engineers and architects, so the scope we recommend reflects only the findings.
What access do you need to test a facade leak?
We need exterior access to the wall area under investigation and interior access to the rooms where water appears, including above ceilings where possible. Depending on height and site conditions that may mean a lift, swing stage or rope access. We also need a water supply on site and cooperation from tenants in the affected spaces.
The leak stopped. Is there still a reason to investigate?
Yes. A leak that appears seasonally or only in certain wind conditions is still an open path, and the wall keeps wetting whether or not anyone sees it. Because testing reproduces the conditions deliberately, we do not have to wait for the next storm. Investigating during a dry period also makes interior observation easier.
Can your findings support a warranty or insurance claim?
Our reports document what was tested, in what sequence, and what resulted, with photographs and the reasoning connecting the entry point to the interior damage. That record is often used by owners in warranty, insurance or contract discussions. We report what the evidence supports, and our conclusions do not change based on who benefits from them.
What should we gather before the investigation starts?
Anything that establishes history: dates and photographs of past leaks, weather at the time if known, previous repair invoices or scopes, and original or renovation drawings for the wall assembly. Building staff who have watched the leak occur are often the most useful source of all. Missing records do not stop the work.
