Leak Walk Before Repairing Duct

Sealing, Leakage, Mastic & Pressure Testing⚠️ VERIFYField workflow

Core Answer

Find the actual leak path before smearing more sealant. Walk the joint, seam, access door, tap, cap, and temporary test closure in a consistent order.

What to Check First

Confirm the test section and pressure condition
Listen and feel only where the test procedure allows
Mark each suspected leak before repairing
Separate mechanical fit problems from sealant problems
Photograph repeat failures before they disappear under mastic

Ask Foreman

The leak is showing at [joint/seam/access/tap]. Do you want the mechanical fit corrected first, or is the approved sealant repair enough here?

Text to Foreman

Do Not Do This

Do not bury a loose joint, crooked flange, open seam, or failed access-door gasket under more mastic.

Why This Matters

Random repairs waste time and can hide the real mechanical problem until the retest.

Verify against: project leakage-test plan, approved sealant data, drawings/specs, foreman and test contractor direction.
