One decade built a big share of Waldwick
The borough's Housing Element, adopted June 23, 2025, counts 3,486 housing units. Of those, 43.2 percent, or 1,506 homes, were built from 1950 to 1959. Another 10.9 percent date from before 1940, 9.7 percent from the 1940s and 13.7 percent from the 1960s, so roughly 64 percent of the stock is older than 1960.
Owner-occupancy is about 88 percent. That is a lot of houses reaching their sixth or seventh decade at the same time, which is when water heaters, drains and original lines tend to give out together.
A house from that decade may still carry its original piping, and the only way to know is to look. We check at the entry point and at a cleanout, then explain what we see. If a drain keeps slowing, drain cleaning clears it, and whole house repiping is the discussion when supply lines are failing in several places.
A borough-run water system with hard water
Waldwick makes its own water
Waldwick's water comes from six wells in the Brunswick Aquifer, drilled 170 to 250 feet deep, all inside the borough. The Borough Water Department, at 63 Franklin Turnpike, operates the system. Its 2026 water quality report prints calcium hardness averaging 450 ppm, with a range of 222 to 450, against a New Jersey recommended limit of 250.
The borough began PFAS treatment in July 2024, and it reports that the state has terminated its PFAS consent order. The report does not include results taken after treatment started.

Hard water is hard on equipment. Scale builds up inside a tank and on heating elements, which shortens the life of a water heater and makes it noisy. If you hear rumbling or see rusty water at the tap, water heater repair is the first call. A tankless water heater needs descaling on a schedule in water like this.

Ho-Ho-Kus Brook and the Ida flood
Around September 1, 2021, Ho-Ho-Kus Brook rose more than ten feet in Waldwick and flooded homes during Ida. The USGS and the state's environmental department have published flood inundation maps for the brook through the borough.
If your basement took water then or since, a sump pump that does not start is the first thing to check. For repeated seepage, ask about basement waterproofing.
Where Waldwick sewage goes
The Northwest Bergen County Utilities Authority treatment plant sits in Waldwick, at 30 Wyckoff Avenue, and serves about 75,000 people. Waldwick is one of the towns that sends its sewage there. The borough's public works department handles sewer maintenance.
Before you change a lateral or a sump discharge, ask the building department what it requires. A backup that stays in one house is usually in the private line, and a sewer camera inspection shows where. A sewer line repair follows if the pipe is cracked or rooted.
Permits and the downtown core
According to the borough building department's FAQ at 63 Franklin Turnpike, a hot water heater replacement needs a permit, and you can start it at (201) 652-5300, extension 232. The state's minor work rule (N.J.A.C. 5:23-2.17A) treats a like-capacity swap as notice first, an application within 5 business days and an inspection afterward.
Downtown runs along East and West Prospect Street and Franklin Turnpike, and the NJ Transit station sits near the geographic center of the borough. The restored 1886-87 station building houses the Waldwick Museum of Local History. Shops and restaurants near the center are covered by our commercial plumbing service.

First steps while you wait
These apply to most Waldwick calls, from a failed heater to a burst line.
Shut the water
Close the main valve where the line enters the house. For a heater, close its cold inlet valve.
Turn off the heater
Switch a gas heater to pilot or off, or flip an electric heater's breaker. Do this only if the tank area is dry.
Limit drain use
If a line is slow or backing up, stop running water to it.
Document it
Photograph damage before you move anything, for your insurer.

Yes. The borough building department's FAQ says a hot water heater needs a permit, and you can call (201) 652-5300, extension 232. We confirm the process before we begin. See water heater installation for planned swaps.
The borough's 2026 report prints calcium hardness averaging 450 ppm, well above the state's 250 ppm recommended limit. Scale builds up on fixtures and in water heaters. A flush or a softener plan can reduce the effect.
Shut off power to the basement if water is near outlets, then call us to check the sump pump and floor drains. Photograph the high-water line. The USGS flood maps for the brook show how high the water has reached.
Waldwick's water system belongs to the borough, so a main-line problem goes to the Water Department at 63 Franklin Turnpike. For a leak inside your house or on your private side, call us.
