WHAT WE INSPECT

From single-tenant retail buildings to large multi-story complexes, our commercial inspection services cover every critical system your investment depends on.

01
Structural Systems
Evaluation of foundations, load-bearing walls, beams, columns, roof structures, and framing. We identify settlement, cracking, deterioration, and code compliance concerns.
Foundation Framing Roof Structure
02
Electrical Systems
Inspection of service panels, sub-panels, wiring, outlets, breakers, and ground fault protection. Commercial electrical systems demand higher scrutiny — we deliver it.
Service Panels Wiring GFCI/AFCI
03
HVAC Systems
Assessment of heating, ventilation, and air conditioning units, ductwork, and controls. Commercial HVAC represents a major capital cost — know its true condition before you buy.
Heating Cooling Ductwork
04
Plumbing Systems
Inspection of supply lines, drain, waste and vent systems, water heaters, backflow devices, and fixtures. We identify leaks, improper installations, and aging infrastructure.
