Home Inspector in Commerce City, CO

Commerce City is two cities: 1950s–60s homes in the historic core near the refineries, and 2000s–present master-planned Reunion and Buffalo Run north of 96th. Old sewer and electrical in the south, expansive soil and builder shortcuts in the north. Justin inspects both with a structural engineer's eye and a buyer's deadline in mind.
