Park Slope's brownstone rows sit in one of the city's largest historic districts, where many blocks still carry original bluestone sidewalks — so sidewalk violations here aren't just a repour, they're a materials question.

JBS Concrete Pros serves Park Slope from our yard at 9101 120th Street in Richmond Hill, Queens with concrete work, masonry, contracting, and 10–40 yard roll-off dumpster rental — same-day delivery on calls before noon, Monday–Saturday. ZIP codes covered: 11215, 11217.
On designated landmark blocks the LPC requires in-kind sidewalk repair — bluestone where bluestone exists — while standard blocks get DOT-spec concrete; we do both, plus stoop restoration, rear-extension foundations, and containers on curb permits.
DOT violations cleared: permit, repour, dismissal.
10–40 yd roll-offs, same-day before noon.
Cracks, bowing, underpinning, waterproofing.
4,000 PSI flatwork, stoops, retaining walls.
Tuck-pointing, lintels, façade restoration.
New builds, additions, gut renovations.
On landmarked bluestone blocks, repairs must generally match in kind; we price bluestone reset against LPC-approved alternatives and file accordingly.
Yes — excavation, underpinning where the party wall requires it, and the new foundation, with DOB filings handled.
