From the Duck Pond to County Road: how location shapes a Demarest call
Demarest is built around the Duck Pond, a stretch of the Tenakill Brook near Hardenburgh Avenue and Piermont Road. The Demarest Railroad Depot, listed on the National Register of Historic Places since 2004, sits nearby. Where you live relative to the pond, the brook and the hill roads changes how water behaves around your house.
A lot near the brook may see more groundwater after heavy rain. A house on higher ground may have dry basements but more roof and gutter exposure. Tell us where you are when you call, and we plan the equipment around it.
Water spreading in Demarest: what to do now
If water is moving through a Demarest house, call the 24/7 emergency line. A same-day response is offered when a crew is available and dispatch runs around the clock.
Demarest is about two miles northeast of Dumont. The borough covers 2.1 square miles and had 1,680 housing units in the 2020 Census. County Route 501 and County Route 505 run through it. Heavy rain can overwhelm gutters and downspouts anywhere in the borough, so a clogged gutter is worth clearing before a storm.
Neighborhood features and their water risks
Here is how local features tie into a typical call:
- Homes near the Tenakill Brook and the Duck Pond: check the FEMA map for your address and watch basements after heavy rain.
- Streets near Hardenburgh Avenue: roof and gutter overflow after storms is a frequent cause.
- Houses near County Road School and the depot: older construction, so ask about plumbing materials.
- Homes served by Northern Valley Regional High School's neighborhood: standard suburban plumbing, with finished basements common.
These are patterns, not predictions. A moisture meter, not a map, tells us where the water went.
Storm and pipe damage in Demarest cannot wait for morning
Call the 24/7 line.
If water is still spreading: before we arrive
Use these steps while you wait.
Close the valve
The main shutoff is near the meter or where the line enters the basement.
Avoid the electric hazard
Do not enter standing water that touches outlets or cords.
Lift contents
Move rugs, small furniture and electronics to dry spots.
Photograph first
Take pictures before anything is moved.
Who to call first in Demarest: 911, the utility, or us
Some water damage involves more than water. If you see sparks, smell gas, or a ceiling is about to collapse, call 911 first. Demarest has a volunteer fire department that was established in 1894, with its station on Park Street, and a volunteer ambulance corps established in 1961.
For an electrical hazard, call the electric utility. For a gas smell, call the gas utility from outside. Then call our 24/7 line. We handle the water and the damage, and we do not handle the utilities.
If a water main or a street pipe has broken, the borough's public works can help. If water is coming from inside your own house, our line is the right call once the source is shut off.
Services Demarest homes call us for
Calls from Demarest often involve a wet ceiling, a leaking supply line or an overflowing gutter. See our ceiling water damage repair and storm water damage cleanup pages. To the south and west, our pages for Cresskill and Haworth cover neighboring areas. Tell the dispatcher which side of the Duck Pond you are on, since that helps the crew find the house on the first pass.
