Chimney Repair for Union City chimneys
Union City's brick chimneys rise from attached multifamily buildings on the crest of the Palisades, exposed to wind off the Hudson on one side and crowded by neighboring chimneys on the others. Most were built for coal and now vent gas boilers and water heaters; some are shared across a party wall, and some have been abandoned after conversions to direct-vent systems.
We inspect, repoint, rebuild, reline and cap chimneys across Union City, flash chimneys properly where they pass through flat membrane roofs, and seal or remove abandoned chimneys that have become leak points. Most of the work is done from the roof, with materials brought up through the building or by hoist.
Union City housing
Union City's housing is almost entirely flat-roofed multifamily: brick and wood-frame two- to four-family houses and small apartment buildings on narrow lots, attached or inches apart, with front parapets or cornices and rear scuppers. Many buildings have been re-roofed with layers of built-up roofing and modified bitumen. Roof hatches, skylights and brick chimneys are standard, and rooftop access is usually through the top-floor unit or a common stair.
Weather & exposure
On the crest of the Palisades, Union City roofs take wind directly off the Hudson River with no shelter. Nor'easters drive rain against parapets, coping and chimneys and lift loose membrane edges. Density means debris from neighboring roofs ends up in your scuppers, and ponding follows. Summer heat on dark membranes ages them quickly, and freeze-thaw opens joints in coping and crowns every winter.
Repair, repoint or rebuild in Union City
We start with an inspection of the exterior and, where the chimney serves an appliance, the flue interior. Repoint sound brick with worn joints; rebuild loose upper sections from a solid course with a proper crown and stainless cap; reline unlined or damaged flues serving gas appliances with correctly sized stainless steel liners. For party-wall chimneys, we identify which flues serve which building and coordinate with the neighbor. Unused chimneys are capped and sealed or removed below the roofline.
Do chimney work before a roof replacement so the new flashing is set into sound masonry and no masonry debris falls on the new membrane.
