Commercial work across Brooklyn & Queens

Real jobs, each with a full project write-up.

BUSHWICKCommercial copper rough-in: new build
→
Full plumbing rough-in for a commercial buildout on Flushing Avenue. Threaded copper supply runs, new waste stack connections, and all rough-in work before slab.
MASPETHMechanical piping: commercial building
→
Mechanical room piping installation for a mid-size commercial building in Maspeth. Copper supply manifolds, zone valves, insulated runs to multiple floors.
GLENDALEFan coil unit: ceiling mount & copper connections
→
Ceiling-mounted fan coil installation in a Glendale commercial space. Copper supply and return connections, condensate drain, and zone control wiring coordination.
WILLIAMSBURGOverhead Distribution Manifold: Commercial Loft Buildout
→
A Williamsburg commercial loft buildout needed a central overhead manifold to distribute plumbing to multiple tenant zones before the ceiling was closed. We designed and installed the overhead assembly, copper mains, a branched manifold with ABS branch connections, and zone isolation, giving the building owner a system that can be expanded or modified as tenant layouts change.
ASTORIACommercial Stainless Fixture Install: Food Service Restroom
→
An Astoria food service operator renovating a commercial restroom needed fixtures that would pass a DOH inspection, not residential-grade equipment. We set a floor-mount flange, installed a commercial stainless steel toilet with a commercial flush valve, and roughed in to meet the Department of Health's requirements for commercial food service facilities.
SUNSET PARKFull Commercial Plumbing Rough-In: Warehouse-to-Office Conversion
→
A Sunset Park warehouse-to-office conversion needed full plumbing rough-in before the dropped ceiling closed, we ran copper supply and PVC drain lines overhead across the entire floor plate, connected to the building's main stack, and left properly positioned stubouts at each future fixture location, all permitted and inspected before the GC proceeded with finishes.
GREENPOINTNew Bathroom Tub Rough-In: Mixed-Use Building Addition
→
A Greenpoint mixed-use building conversion was adding a new full bathroom on the second floor where none had existed before. With metal stud framing going up and the ceiling still open, we roughed in the tub waste and overflow, positioned supply for the valve, and set the tub before framing closed around it. Getting the rough-in right before framing is the only way to avoid expensive tearout later.
MASPETHFloor Drain Rough-In: Concrete Slab Commercial Conversion
→
A Maspeth industrial building converting warehouse space to commercial use needed new floor drains added to a concrete slab, which meant core drilling, setting drain bodies, and connecting to the existing waste line below. We handled the full slab rough-in, including flange setting and slope to drain, before the new concrete pour covered everything.
BEDFORD-STUYVESANTABS Waste Line Replacement: Pre-War Commercial Building
→
Failed cast-iron drain branches in a Bed-Stuy pre-war commercial building were causing recurring backups and visible corrosion through the brick wall. We replaced the deteriorated sections with new ABS waste lines run along the exposed brick, added proper cleanouts, and connected back to the main. No jackhammering required, the new runs are surface-mounted and fully accessible for future service.
