Thermal Imaging Inspection
Using an infrared camera to detect temperature differences in building surfaces, revealing hidden moisture, insulation gaps, air leaks, and electrical issues.
The Full Picture
Thermal imaging (infrared thermography) captures the surface temperature of objects and displays them as color-mapped images. In building inspections, temperature differences reveal problems invisible to the naked eye: missing insulation appears as cold spots on walls, moisture intrusion shows as cool areas where evaporation is occurring, air leaks appear as temperature gradients around penetrations, and overloaded electrical connections show as hot spots. The technology doesn't see 'through' walls — it reads surface temperature variations that indicate what's happening behind them.
Why It Matters
Why field professionals need to document this
Thermal imaging transforms subjective observations into visual evidence that clients immediately understand. A home inspector saying 'there might be missing insulation' carries far less weight than showing a thermal image with a clear cold spot on the wall. For energy auditors, thermal imaging paired with a blower door test is the gold standard for identifying air sealing priorities. The challenge is documenting dozens of thermal images with annotations and context in a professional report.
In a Report
How this shows up in findings
Here's how a thermal imaging inspection finding looks in a professional field report generated by ReportWalk:
Cold spot on second-floor ceiling indicating missing insulation in attic above
Moisture pattern on basement wall consistent with active water intrusion
Hot spot on electrical panel breaker — 40°F above ambient, overloaded circuit suspected
