I provide a free Infrared/thermal scan on every home inspection. Infrared technology can allow us to see otherwise hidden defects such as missing insulation, moisture inside walls, air duct issues etc. I have residential thermography training through InterNachi and United Infrared (see certificates below).
Check out the pictures below for some of the interesting things we are able to find.
***some defects require proper temperature differentials (outside vs inside) to be found and will not be easily discovered on a mild day
EXAMPLES OF MISSING INSULATION / AIR LEAKAGE
missing insulation - raised ceiling
missing insulation - ceiling joist bay
missing insulation - under attic service catwalk
air leak from attic due to no firestop around chimney vent/blocking
missing insulation
insulation not replaced after drywall patch
missing insulation in exterior wall
air leak from damaged weatherstripping
EXAMPLES OF MOISTURE & HVAC PROBLEMS
water leak inside wall
moisture intrusion due to missing refrigerant line insulation
moisture wicking into wall from leaking fridge water line
