Brownstone underpinning, basement lowering, sidewalk violations and stoops on tight blocks — Brooklyn is structural work, and it's where JBS's engineered concrete crew does its most serious jobs.
JBS serves all of Brooklyn with concrete and masonry: brownstone underpinning and basement lowering, foundation repair, DOT sidewalk violation removal, stoops and brick pointing.
Brooklyn's rowhouse and brownstone stock drives a specific kind of work: cellar dig-downs that need engineered underpinning, party-wall-adjacent excavation, lime-mortar pointing that can't be done with modern hard mortar, and street-tree sidewalk damage on landmarked blocks. JBS self-performs the underpinning and coordinates the DOB filings.

Yes — we match mortar hardness and color to the original lime-based mortar so the brick faces don't spall, which is the failure you see when pre-war walls get repointed with hard modern mortar.
