Multifamily window programs are the Bronx work: whole buildings, floor by floor, in occupied rentals from Highbridge to the Grand Concourse.
The Bronx is multifamily. The typical job is a building of twenty-five to a hundred units, occupied, where every window is replaced on a schedule that residents have seen in advance and the building never stops being lived in. The Elston at 990 Woodycrest Avenue in Highbridge is the model: twenty-five units on Aluplast uPVC tilt-turn windows, installed in two phases around occupancy, with the performance data documented for the owner’s compliance file.
The building stock is prewar six-storey walk-ups and elevator buildings along the Grand Concourse and in Fordham and Kingsbridge, postwar towers, and the Riverdale co-ops. The choice between uPVC and aluminum is usually cost per opening against facade exposure, and we price both.

Most Bronx window work is on rent-stabilised or affordable buildings where the owner is replacing windows as a capital improvement, often tied to Local Law 97 or an energy program. The documentation — NFRC ratings, unit counts, before-and-after — matters as much as the installation, and we produce it. Riverdale and Parkchester co-ops follow the alteration-agreement process.

Yes. That is the typical Bronx job: floor by floor, one opening open at a time, weather-tight by end of day, on a schedule residents have seen in advance. The Elston was 25 units in two phases.
Usually uPVC for cost per opening and thermal numbers; aluminum where the facade is exposed or the openings are large. We price both.
Yes: unit performance data, NFRC ratings and counts go into the owner’s compliance file.
