What We Offer
Forensic Diagnostic Chimney Audit
Our core service. A clinical, data-driven evaluation using thermography, endoscopy, UPV meters, and moisture analysis—delivered with a sealed engineering report.

The Gap: Visual vs. Thermal Heat Transfer Scan
What the Eye Can’t See
Standard visual inspections only reveal surface-level issues. Our thermal heat transfer scanning detects hidden anomalies—heat breaches, moisture pockets, and insulation gaps—that are invisible to the naked eye.
The side-by-side comparison shows the dramatic difference between what a standard visual inspection reports versus what our forensic technology uncovers.
