Home inspections & commercial inspections by a qualified inspector with a construction background = real world understanding of structures. Add the use of thermography (infrared imaging) essentially giving me a 6th sense to observe temperature differences & patterns. Abnormal temperatures found with the infrared scan can point out; wet building materials; missing insulation or air leaks; HVAC issues; energy loss; overheating electrical equipment; non-invasive stucco & roof inspections; etc....
