What Jersey City’s housing means for repairs

Jersey City has two distinct housing stocks. About 42% of homes predate 1960, including brownstones in Hamilton Park and Van Vorst Park and two- and three-family frame houses in The Heights, Greenville and Bergen-Lafayette. About 30% were built since 2000, mostly high-rise and mid-rise condos along the waterfront and around Journal Square.

Only about 7% of homes are single-family detached, and only about 28% are owner-occupied, so most repairs involve a landlord, a condo board or both. Gas heats about 61% of homes, often through old boilers in older buildings, while newer towers use electric heat pumps. The median home value is about $566,900. In older homes, expect cast iron drains, galvanized pipes and patched plaster; in new condos, expect leaks from the unit above.

Weather that wears on Jersey City homes

Jersey City has cold winters, hot humid summers and a waterfront that floods. Hurricane Sandy in 2012 flooded parts of downtown, and heavy rain still causes street and basement flooding in low-lying areas. Salt air near the Hudson corrodes metal railings, HVAC units and window hardware. Nor'easters bring wind-driven rain that leaks through brownstone cornices, window frames and flat roofs. Freeze-thaw cracks stoops and steps, and brick needs repointing. Older boilers work hard through long cold snaps, and humid summers bring mold to basement units.

Common repairs in Jersey City

• Bathroom leak into the ceiling below

  In Jersey City multi-family homes and condos, a failed tub or shower seal shows up as a stain on the ceiling of the unit below.

• Stoop and brownstone step repair

  Brownstone stoops crack and flake from freeze-thaw and need patching or resetting.

• Boiler service and radiator repair

  Many older Jersey City homes still heat with boilers that need service before each winter.

• Siding and trim repair

  Frame houses in The Heights and Greenville have aging vinyl, aluminum or asbestos siding and wood trim that needs repair.

• Basement water and flood cleanup

  Low-lying blocks near the waterfront take on water in heavy rain and storm surge.

Fix guides for Jersey City homeowners

• Bathtub is separating from the wall

  In Jersey City's stacked units and condos, a tub pulling from the wall is a common source of leaks into the unit below.

• Ceiling is stained and sagging after a water leak

  Plaster and drywall ceilings in Jersey City multi-family homes sag after leaks from bathrooms upstairs.

• Bricks on the porch steps are loose, missing or crumbling

  Brick and brownstone stoops in downtown Jersey City lose mortar to freeze-thaw.

• Sewage backs up into the basement floor drain

  Low-lying Jersey City blocks can see sewage backups during heavy rain because many streets drain into a combined system.

Seasonal checklist

Fall

Have the boiler serviced and bleed radiators before heating season, especially in older two- and three-family homes.

Winter

Salt and shovel the stoop gently; ice in cracked brownstone speeds up spalling.

Spring

Check basement walls and the floor drain after nor'easters and heavy spring rain.

Hurricane season

If you live near the waterfront, move valuables and equipment off the basement floor and check your sump pump before storms.

Common questions

My upstairs neighbor's bathroom leaks into my Jersey City condo. What now?

Tell your neighbor and the building manager in writing, and photograph the damage. A plumber can find whether the leak is from a supply line, a drain or a failed tub seal. Your condo documents and insurance policies decide who pays for which part.

Does my Jersey City frame house have asbestos siding?

Some older two- and three-family homes in Jersey City were covered with cement-asbestos shingles in the mid-1900s. Intact siding is generally left alone or covered. If you plan to remove or cut it, have it tested first.

How do I keep my Jersey City basement dry?

Make sure gutters and downspouts carry water away, seal cracks in the foundation, and run a dehumidifier in summer. Near the waterfront, a sump pump and backwater valve help during heavy storms. A contractor can assess what your basement needs.
