Thermal Image Home Inspection
Hidden by the naked eye. Water infiltration outside corner
To the naked eye, nothing. Thermal imaging shows the upper bathroom toilet leaking. Confirmed with moisture meter.
Water coming in from the roof over garage. Lack of correct flashing.
Water penetration blind to the naked eye.
Shows lack of insulation around the HVAC air ducts in attic.
Shows a power drain, over heated switch. Undetected by the naked eye.
Water penetration between lower window sash and jamb.
Shows cold spot in attic. Lack of insilation in corner.

Benefits of Thermal Imaging in the detection of:
-
Water infiltration (roof leaks located with recent rain fall within 24~48 hours)
-
Cold air infiltration
-
Excessive moisture in building materials
-
Stud / Joist / Beam / Rafter placement and structure
-
Insulation gaps, insufficient and unevenness
-
Electrical drops, panels, breakers, switches and wire connections
-
Heating and cooling duct placement, insulation, air leaks
-
Pipe location
-
Special Inspections
-
Pest infestation
-
Energy audits
-
Insurance claims
-
Thermal Imaging Limitations
-
Thermal imaging only displays surface temperatures of solid objects.
-
IR detects the temperature based upon wavelength of the light emitted by the object (longer wavelength, colder). IR, therefore, does not show the temperature of objects that reflect light, (glass, shiny metal, light colored objects in direct sunlight).
-
IR, does not “see through walls”, but only displays the very slight differences in surface temperature of the wall. Images of areas “behind” and not in contact with walls depends upon the temperature difference of the area. It is easier to see “hot” objects because they will be radiating heat to the not-in-contact surface. .
-
Careful adjustment of the range of temperatures displayed is important to proper imaging and interpretation.
-
Thermal imaging camera does not look thru wall, nor is it a xray machine. Does not produce any type of radio activity.
