Flooded basement cleanup in North Arlington, New Jersey

What to do right now

1. 1

   Stay on the stairs until the power is off

   In mid-century houses the panel, furnace and water heater usually share the basement. If you cannot cut the basement circuits from a dry place, call the utility or an electrician and wait.

2. 2

   Decide whether it came from inside or outside

   Check whether it was raining hard, whether water is seeping along the base of the walls or through a window well, and whether any pipe or appliance is visibly leaking.

3. 3

   Mark and photograph the high-water line

   Use a pencil line on the wall and photograph it next to something with a known size. The depth matters to anyone assessing the loss.

4. 4

   Do not pump a deeply flooded basement all at once

   When the ground outside is saturated, pumping the basement dry too quickly can leave the walls facing unbalanced pressure. A contractor will lower the level in stages.

5. 5

   Separate what is salvageable

   Once it is safe, move photographs, documents and anything of value up and out. Leave upholstered items and mattresses for assessment; floodwater usually condemns them.

Warning signs worth acting on

• Water entering along the joint where the floor meets the wall during or just after heavy rain, which points to outside water rather than plumbing.
• A tide-mark of silt on the walls after the water drops, typical of floodwater rather than clean supply water.
• Panelling or drywall that has wicked water well above the visible flood line.
• A furnace or water heater base that sat in water, even briefly.
• A recurring damp patch in the same corner after every storm in a house inside the mapped flood zone.

Who you should call, and why

In North Arlington, start with the cause. If water came from a pipe or fixture, a plumber repairs it and a restoration contractor dries the basement. If it came from outside, the restoration contractor is the first call for cleanup and a waterproofing contractor comes later to look at how it got in. Renters, who are the majority here, should report to the landlord before arranging anything for the building itself.

• Water-damage restoration contractor

  Pumps down, removes contaminated porous material, cleans and dries, and documents depth and duration for any claim.

• Foundation or waterproofing contractor

  Assesses where outside water is entering and what drainage or sealing would reduce it next time.

• Licensed electrician

  Checks basement circuits, outlets and equipment connections that were submerged before power is restored.

• Licensed plumber

  Needed if the water came from inside, or if the water heater or drains were affected.

What a professional normally does

1. Pumps down in stages

   Free water is removed with submersible pumps and extractors, with the level brought down gradually when the surrounding ground is still wet.

2. Removes what floodwater has condemned

   Carpet, pad, insulation and the lower portion of drywall that contacted contaminated water are cut out and bagged rather than dried in place.

3. Cleans and treats hard surfaces

   Concrete, block and framing are cleaned of silt and treated before drying, because drying a dirty surface locks the contamination in.

4. Dries the structure

   Dehumidifiers and air movers run until framing and masonry readings match unaffected material. Block walls hold a lot of water and can take longer than people expect.

5. Records depth, duration and removal

   Photographs, measurements and a log of what was removed and why. In a flood loss, that list is the core of any claim.

What drives the cost

There is no fair way to put a price on a page. A basement cleanup is driven by measurable things, and floodwater from outside pushes several of them in the expensive direction.

• Depth of water and whether it came from outside, which makes it contaminated and increases what has to be removed.
• Whether the basement was finished, with carpet, walls and ceiling to strip out.
• How long the water stood before pumping started.
• The size of the basement and how much stored property needs to be moved or disposed of.
• Masonry type: block walls hold more water than poured concrete and dry more slowly.
• Whether the furnace, water heater or electrical equipment has to be replaced.

Insurance documentation checklist

Whether a flooded basement is covered depends on the cause and on the policies you hold, and that decision belongs to your insurer. The NFIP and FEMA figures for North Arlington show far more flood-affected owners than flood claims, so do not assume either way — gather the evidence and ask.

• ☐Photographs of the high-water line and of the point where water entered.
• ☐A note of the weather at the time, with the date and approximate time the water appeared.
• ☐Your homeowners declarations page and any separate flood policy, including its effective date.
• ☐Photographs of each damaged item before disposal, plus a written list.
• ☐Make, model and serial numbers of the furnace, water heater, washer and dryer if they were in the water.
• ☐The contractor’s removal list and moisture logs.
• ☐Receipts for pumps, fans or disposal you paid for yourself.

Local context

Around 21.3 per cent of North Arlington’s land area lies in the FEMA 1 per cent annual chance flood zone, across a housing stock with a 1954 median build year. That combination means many flooded basements here take water from outside rather than from a pipe, and FEMA and NFIP records — 92 owner-occupants registered for Sandy assistance against 57 lifetime NFIP claims in the ZIP code — suggest many of those basements are cleaned up with no flood policy behind them.
