Thermal imaging is a non-contact, non-invasive method of detecting leaks and moisture by measuring infrared radiation emitted from surfaces. A thermal camera converts heat into a visible colour map. Water and moisture have distinct thermal signatures, making leaks visible even when hidden inside walls, ceilings, under floors, or below concrete.
Thermal imaging works for water leaks, moisture damage, and energy loss. It's particularly useful for detecting leaks in walls and ceilings where other methods can't reach, and for confirming the extent of moisture damage before repair begins. The camera doesn't damage anything — it just sees temperature differences.
