What is actually going on
Cleaning up a flooded basement means removing the water, deciding what is ruined, cleaning and then drying the structure so it does not grow mould. In a single house that is one owner’s problem. A lot of Hackensack basements are not like that. In two- and three-family houses and in apartment buildings, the basement is typically shared: it holds the boiler, the electrical panel, laundry machines and storage cages or corners where several households keep their belongings. When it floods, that creates questions that have nothing to do with drying technique. Who controls the boiler and panel? Whose possessions were damaged, and who photographs them before they are thrown away? The landlord or managing agent arranges the cleanup of the building, but each tenant’s belongings are a matter for that tenant and their own renters insurer, if they have one. The physical cause matters as well. Around 18 per cent of the city’s land area sits in the FEMA mapped flood zone, with the Hackensack River along its eastern edge, so some basements take water from outside during heavy weather rather than from a pipe — which changes both the cleanup and the insurance conversation.
What to do right now
Do not go into a shared basement with standing water
The boiler, panel and laundry circuits are usually down there. Report it to building management or the superintendent and let them isolate the power.
Report it in writing
Send the landlord or managing agent a message with the time and a photograph from the stairs. If several tenants are affected, each should report.
Photograph your own stored belongings
Before the building’s cleanup crew bags anything, ask to photograph what is yours. Once it is in a skip there is no record.
Note how the water arrived
Was it raining hard? Is water coming through a wall or window well, up through a floor drain, or from a pipe? Tell management what you saw.

Warning signs worth acting on
- Water seeping along the base of a basement wall during heavy rain, which points to outside water rather than a building pipe.
- Damp or flaking paint in a ground-floor garden apartment unit along the wall closest to grade.
- Water around the base of the boiler or water heater in a shared utility room.
- A floor drain that fills rather than empties during storms.
- Storage boxes on a basement floor that are soft or stained at the bottom.
Who you should call, and why
For a Hackensack house you own, call a restoration contractor for the cleanup and, depending on the cause, a plumber or waterproofing contractor. For an apartment building, a two- or three-family rental or a condominium, the landlord, managing agent or association arranges the contractors for the shared basement; tenants report, document their own belongings and contact their own insurer.
Water-damage restoration contractor
Pumps down, removes contaminated porous material, cleans and dries the basement and records what was removed.
Licensed electrician
Checks the panel, laundry circuits and any equipment that was in the water before power is restored to the basement.
Foundation or waterproofing contractor
Assesses how outside water is getting into the basement, which matters most for buildings near the mapped flood zone.
Licensed plumber
Needed if a building pipe, the water heater or the drain line caused the flooding.
What a professional normally does
Coordinates with building management
In a shared basement the contractor works for the owner or association and needs access to the utility room, storage areas and sometimes individual units.
Pumps out and classifies the water
Outside floodwater and drain backup are treated as contaminated under the IICRC approach, which means more porous material goes.
Removes ruined materials and contents
Wet drywall, insulation and carpet are cut out; residents’ belongings should be photographed before disposal.
Cleans, treats and dries
Hard surfaces are cleaned and treated, then dried with dehumidifiers until readings return to normal.
Before you let anyone start work
Most disputes with a restoration company start with something that was not agreed in writing on the first day. These take a few minutes, even in an emergency.
- Get a written scope and estimate before work starts, with the drying and any rebuild as separate documents.
- Look up the company’s New Jersey contractor registration yourself, and ask for proof of liability insurance.
- Ask who will be in your home, and whether any of the work is subcontracted.
- Read any authorisation or assignment-of-benefits form before you sign it.
- Photograph your belongings before anything is moved, and ask for an inventory of anything taken away.

What drives the cost
We do not give prices. For a shared Hackensack basement the cost is borne by the building, while each household’s belongings are a separate matter; the factors below drive the building’s side.
- Depth and source of the water, which determines how much must be removed.
- The size of the basement and how much stored property must be cleared.
- Whether the boiler, water heater, laundry equipment or panel was affected.
- Whether parts of the basement were finished or used as living space.
- How long it took to start pumping, which can be extended by access problems.
Insurance documentation checklist
Whether any part of a basement flood is covered is decided by the relevant insurer. In Hackensack, with about 63 per cent of homes rented according to the US Census Bureau, the building’s policy and each tenant’s renters policy are separate, and flood from outside is excluded from standard property policies and needs its own flood cover. Document your share clearly.
- Your written report to management, with time and photographs.
- Photographs of your stored belongings before disposal, with a list.
- A note of the weather and how the water entered.
- Your renters or homeowners declarations page, and any flood policy.
- Purchase dates or receipts for damaged items where you have them.
- Any written confirmation from management about the cleanup.
Local context
About 18.0 per cent of Hackensack’s land area lies in the FEMA 1 per cent annual chance flood zone, with the Hackensack River along the eastern boundary, and roughly 63 per cent of occupied homes are rented. Many basements here are shared spaces in two- and three-family houses and apartment buildings, holding the boiler, the panel and residents’ storage, so a flood is both a building problem for the owner and a contents problem for each household.

Common questions
My belongings in the building basement were ruined. Who pays?
The building owner’s insurance generally concerns the building; your belongings are usually a matter for your own renters policy, if you have one. Whether a particular loss is covered is for the insurer to decide. Photograph everything before the cleanup crew removes it.
Is a basement flood near the river a flood claim?
If water entered from outside at ground level, insurers typically treat it as flood, which standard homeowners and renters policies exclude. Flood cover is separate. You can check whether an address is in the mapped zone on the FEMA Flood Map Service Center.
Should I clean my storage area myself?
Wait until building management confirms the power is isolated and the water has been classified. If it was floodwater or drain backup, wear gloves and boots, and photograph items before you discard them.
