Brownstone underpinning, basement lowering, sidewalk violations, and containers 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, masonry, and roll-off dumpster rental: brownstone underpinning and basement lowering, foundation repair, DOT sidewalk violation removal, brick pointing, and same-day 10–40 yard containers with DOT street permits handled for curbside placement.
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 — and on streets with no driveways, our office pulls the DOT permit so the container can sit legally at the curb.

Yes, with a DOT street placement permit, which our office files as part of the rental. If you have a driveway or yard access, no permit is needed.
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.
