Alliance General Contracting NY Inc is a licensed and fully insured contractor operating out of 2362 Westchester Ave in the Bronx.

Sidewalk work in New York City is governed by the Department of Transportation, which specifies slab thickness, scoring pattern, cross slope, expansion joint placement and curb-cut detailing. Property owners who hire someone unfamiliar with those specs often end up re-doing the flag after a DOT inspection. We build to the published standard the first time.

Why NYC Properties Need Concrete Sidewalk Installation and Repair
Concrete either lasts thirty years or cracks in two, and the difference is almost always base preparation, reinforcement and control joints not the mix itself. Alliance General Contracting NY Inc pours driveways, sidewalks, steps, slabs and foundations across the Bronx, Brooklyn, Queens and Manhattan with compacted sub-base, proper steel and joints cut before the slab decides where to crack on its own.
Across the four boroughs we work on two-family brick homes, pre-war walk-ups, semi-detached row houses and mixed-use storefront buildings; limestone and brownstone rowhouses, three-family frame homes and converted industrial lofts; attached brick colonials, Tudor-style singles, garden co-ops and two-family investment properties; pre-war co-ops, brownstone conversions, tenement-era multifamily buildings and high-rise condo interiors. Each of those building types ages differently, and concrete sidewalk installation and repair is specified accordingly what suits a detached Bayside colonial is not what suits a shared-wall Bed-Stuy rowhouse or a fifth-floor pre-war apartment in Washington Heights. That judgment is the part you are really hiring a licensed contractor for.
Signs You Need Concrete Sidewalk Installation and Repair Now
Property owners usually call us after they notice one of the following: visible staining or discoloration on interior finishes, a musty smell that returns after every rain, hairline cracking that keeps widening season over season, materials that are loose, spalling, sagging or separating, rising utility bills that suggest a compromised building envelope, or a condition flagged on an inspection or violation notice. None of these get cheaper with time. Water in particular finds a path and then keeps using it, and by the time damage is obvious the repair has usually doubled in scope.
If you are seeing any of that, book the free estimate. We will tell you honestly whether it is urgent, whether a targeted repair will do, or whether you can safely budget for it next season.
Timeline and What To Expect
After your free walkthrough you receive a written, line-item scope with materials named and allowances stated. Once you approve it we confirm material lead times, arrange any filings the work requires, and give you a start date with a realistic duration. On site we protect the surrounding areas before work begins, keep the space clean at the end of each day, and send you progress photos of anything that will be covered up. When the work is done we walk it with you and close out every punch item before invoicing the balance.
Permits and code compliance are handled as part of the job where applicable. New York City has real requirements around structural work, sidewalks, facades, plumbing and electrical, and doing it properly protects your resale, your insurance position and your neighbors.
