The Park Sloper

Best for structural, concrete, and foundation work

JBJ Renovations

A third-generation Brooklyn contractor (licensed as JBJ Concrete Renovations) based in Red Hook, JBJ is the pick when the job is structural: foundations, concrete, underpinning, framing, and additions, alongside full interior and exterior renovations. If your project starts below grade (a cellar dig-out, a rear extension, shoring up a settling brownstone), this is the structural-first specialist.
