New Brunswick homes and their plumbing
Here is how New Brunswick's homes break down by year built, based on Census estimates for the covered ZIP codes: before 1940 24%, 1940–1959 20%, 1960–1979 19%, 1980–1999 18%, 2000 or later 19%. With that many older homes, original galvanized supply pipe and cast iron or clay drains are still common, so leaks, rust and root intrusion come up often.

What goes wrong in New Brunswick homes
Pre-1960 homes: galvanized pipe and cast iron
44% of homes in New Brunswick's covered ZIP codes were built before 1960, 24% of them before 1940. Houses that old often still have galvanized steel supply lines that rust closed from the inside, and cast iron or clay sewer pipe that cracks and lets roots in. Weak pressure at upstairs fixtures, brown water after a shutoff and slow drains are the usual clues. Typical fixes are whole-house repiping and a sewer camera inspection.
Apartments, condos and attached homes
Only 23% of homes here are single-family detached houses. In attached buildings a leak or clog often involves a shared stack or a neighbor's unit, so it's worth knowing which lines are yours and which belong to the building or HOA, and where your unit's own shutoff is.
Natural gas in most homes
60% of occupied homes here heat with utility gas, so gas water heaters, ranges and dryers are common. That means gas line extensions for new appliances, flexible connector replacements and venting checks when a water heater is swapped. If you smell gas, leave first and call the gas utility from outside. See gas line repair.
Winter freezes
63% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a cold New Jersey winter those are the lines that freeze and split. See frozen and burst pipe repair.
