Verified record
Carl Blomberg is a Winthrop general contractor. BuildZoom's profile lists two Boston permits he pulled in 2014: masonry and structural repair, and a chain-link fence at 804 Huntington Ave. It also lists a Massachusetts construction supervisor licence, #CS-107546, under his name. That permit pair is a dozen years old, so ask what he has been building since, look the licence number up with the state yourself, and get a written scope and a couple of references for the job you have in mind.
