Quick answer
A flooded basement in a New York, NY house needs pumping before cleanup, and water that came in from outside is treated as contaminated, so drywall, carpet and insulation it soaked usually come out. Published guides put extraction and drying at about $4 to $12 per square foot. Stay out if water is near electrical.
Where basement water comes from
Basement water arrives three ways: through the walls and floor as seepage in heavy rain, through window wells and areaways that fill up, or back up through a floor drain. The first two are floodwater; the third is sewage and handled as a sewage backup. Knowing which one it was changes the cleanup and the prevention.
Finished basements lose the most: drywall wicks water up from the slab, carpet and pad soak through and stored boxes collapse. Unfinished basements usually come down to pumping, cleaning and drying the slab and walls.
Signs your basement is taking water
Catch it before the next storm.
White chalky lines on walls
Mineral deposits on masonry show where water has been coming through.
Damp spots after rain
Wet patches on the floor or walls after a storm mean seepage.
A musty basement smell
Constant mustiness means moisture is getting in somewhere.
A sump pump that runs constantly
A pump that never stops, or never runs, is a warning either way.
Water in window wells
Standing water in wells or areaways can pour in through the window.
Heavy-rain seepage
When the ground around a foundation is saturated, water pushes through cracks, the wall-floor joint and porous block. It usually comes in slowly and in the same spots every storm. We pump and dry, remove wet finishes and point out where it entered, so grading, gutters or waterproofing can be addressed.
Sump pump failure
A sump pump that fails in a storm, or loses power, lets the pit overflow into the basement. We pump out, dry and clean, and check the pit and discharge line. A battery backup and a high-water alarm are cheap insurance for the next power cut.
Window well and areaway flooding
Window wells and below-grade areaways collect rain. If their drains clog, water rises until it pours through the window or under the door. The damage is sudden and concentrated under the opening. We clean out and dry, and show you the drain that needs clearing.
Finished basement tear-out
Drywall, carpet, pad and insulation soaked by floodwater come out, usually cut a foot or more above the water line. We bag and remove them, clean and treat the framing and slab, and dry before anything goes back. The rebuild is covered on our reconstruction page.
How a basement flood job runs
Make it safe
Power to the basement is turned off from a safe point before anyone goes in.
Pump and extract
Submersible pumps lower the water, then extractors finish the floor.
Remove
Wet drywall, carpet, insulation and ruined boxes come out and are bagged.
Clean and dry
Slab and framing are cleaned and dried with equipment and daily readings.

Deep basement flooding north of the city and on Staten Island
In Yonkers, rivers backing up in heavy rain have left six to eight feet of water in basements near the Sprain Brook Parkway. On Staten Island, Ida put nearly nine inches of rain on parts of the island. Flooding at that depth is a pump-out first and a cleanup second, and it's why we carry submersible pumps on every basement call.
What to do and what not to do in a flooded basement

| Electrical | Stay out if water is near outlets or the panel | Walk through water to reach the breaker |
| Pumping | Let a pump lower the water gradually | Pump a deep basement fast while the ground is saturated |
| Belongings | Photograph before moving anything | Throw things out before they're documented |
| Appliances | Leave the furnace and water heater off | Restart equipment that sat in water |

Depth
Deeper water needs pumping and reaches more of the wall.
Finished or not
Finished basements lose drywall, flooring and trim.
Water source
Sewage backup costs more to clean than seepage.
Contents
Stored belongings add sorting and removal.
Equipment in the basement
Furnaces, water heaters and panels that got wet need checking.
Access
Tight stairs and small windows slow removal.
Rebuild
Finishes put back after drying add to the total.
Basement flooding questions
What people ask with water on the stairs.
Not if water is near outlets, cords or the panel. Turn off power from a safe point or wait for us.
Water from outside usually needs a flood policy; sewer backup often needs a specific rider. Check before cleanup.
Drywall soaked by floodwater is usually removed above the water line.
Not until a technician has checked any equipment that sat in water.
Fix grading and gutters, clear window well drains and consider a battery backup sump pump.
Usually a few days to a week after pumping, longer for block walls and slabs.
