Floodwater Got Into the House: What to Do
Water from a storm, a river or the Sound came in through the doors or basement and is now sitting inside. Here is what it usually means, whether it is an emergency and what to do now. One call connects you with a local crew, any hour.
Floodwater inside the house is outside water that came in over thresholds, through basement walls or up from saturated ground during a storm, a river rise or a coastal surge. Treat it as an emergency: it counts as category 3 (contaminated) water, it can hide electrical and gas hazards, and soaked materials start to break down fast. Stay out of standing water, keep power off in wet areas, and make one call to reach a local crew.
Where This Water Usually Comes From
- Most common
Coastal storm surge
On the Long Island Sound shoreline, salt water pushed in by a storm and a high tide enters ground floors and basements all at once. A white crust or a salty smell on walls after the water drops points to surge rather than rain.
- Cause 2
Flash flooding from heavy rain
A cloudburst can drop more rain than brooks and storm drains can carry, even far from a big river. Water that arrived fast, carried mud and debris, and drained within hours is usually flash flooding.
- Cause 3
River or stream overflow
Towns along the Connecticut, Farmington, Naugatuck and Quinebaug rivers can see water climb over a day or two. If the water rose slowly and the nearest river or brook was over its banks, this is the likely source.
- Cause 4
Runoff across the yard or street
When the ground is frozen or already soaked, rain and snowmelt run across the surface toward the lowest door, garage or bulkhead. A muddy trail that starts at one entry point usually means runoff.
Is It an Emergency?
Call now if
- Call now if water is touching outlets, extension cords, the electrical panel or the furnace.
- Call now if you smell gas or heating oil anywhere in the house.
- Call now if the water came in with sewage, heavy mud or a chemical smell.
- Call now if floodwater is more than a few inches deep in any room.
- Call now if floors, walls or basement stairs look damaged or unstable.
It can usually wait a few hours if
- It can usually wait a few hours if the water has already drained and nobody needs to walk through what is left.
- It can usually wait a few hours if power to the wet areas is off and nothing new is coming in.
- It can usually wait a few hours if only a garage or an unfinished slab got wet and it is draining on its own.
- It can usually wait a few hours if local officials still say travel is unsafe, so the crew can come once roads reopen.
Still call today: hidden moisture keeps spreading while it waits.
What to Do Right Now
- 1Put safety first Do not wade into standing floodwater inside the house. Keep children and pets away from it, since it can carry sewage, fuel and sharp debris.
- 2Shut off power the safe way If you can reach the main breaker without standing in water, turn it off. If you cannot, call the electric utility and wait for them.
- 3Leave gas to the utility If you smell gas, get everyone outside and call the gas utility or 911 from a distance. Do not flip switches on or off on the way out.
- 4Document before moving anything Photograph the water line on the walls, damaged belongings and the spot where water came in. Pictures taken now are hard to recreate later.
- 5Carry dry things up Move dry papers, medicines, photos and electronics to an upper floor. Leave soaked upholstered furniture and rugs where they are for the crew to judge.
- 6Call for pumping and drying Floodwater needs extraction, removal of soaked materials and cleaning before drying can start. One call connects you with a local crew.
How a Crew Finds the Source and Fixes It
The crew starts by confirming the power is off in the flooded area and checking for gas or fuel smells. Standing water comes out with submersible or truck-mounted pumps, then extraction tools pull water from carpet and low spots. Next the technicians map how high the water really went. Floodwater wicks up drywall and wall cavities above the visible stain line, so moisture meters are run along each wall and thermal imaging shows cold, wet insulation behind finished surfaces. Because floodwater is category 3, porous materials it touched, such as carpet, pad, insulation and the lower part of the drywall, are usually removed with a straight flood cut above the wet line rather than dried in place.
With the soaked material out, the remaining framing, concrete and hard surfaces are cleaned and treated, and salt residue from coastal water is rinsed off so it does not keep pulling moisture from the air. Dehumidifiers and air movers are set for the size of the space, and the crew returns to take readings until wood and concrete reach dry targets. Belongings can be packed out for cleaning. If water pushed through cracks in the foundation, the crew dries what got wet, but a cracked or failing wall itself belongs with a structural engineer.
- 1
Make the house safe
The crew confirms power is off in wet areas, checks for gas or fuel smells, and marks unsafe floors before anyone walks through the flooded rooms.
- 2
Pump out the water
Submersible and truck-mounted pumps remove standing floodwater, then extraction wands pull remaining water from carpet, low corners and floor drains so drying equipment can work.
- 3
Map the wet line
Moisture meters and thermal imaging trace how far water wicked up walls and under floors, so removal follows the real damage instead of the visible stain.
- 4
Remove and clean
Soaked carpet, pad, insulation and lower drywall are cut out and bagged, then framing and concrete are cleaned and treated because floodwater is category 3 contaminated water.
- 5
Dry and verify
Dehumidifiers and air movers run while technicians take daily readings, and rebuilding starts only after framing, subfloor and concrete readings show the structure is truly dry.
How to Keep It From Happening Again
- Move water away from the walls. Keep gutters clear and run downspouts several feet out so heavy rain does not soak the soil right at the foundation.
- Back up the sump pump. Sump pumps stop when the power goes out, so a battery or generator backup keeps one running through a storm outage.
- Store things high. Keep papers, keepsakes and electronics on shelves or upstairs instead of on the basement floor where the first inch of water lands.
- Watch the warnings. When flood or coastal storm warnings are posted, move valuables up and charge phones before the water arrives, not after.
- Seal the low entries. Check bulkhead doors, garage thresholds and basement windows for gaps where surface water can run straight inside.
What It Costs
Floodwater cleanup is priced as category 3 work, usually $7 to $14 per sq ft, with a typical job between $2,500 and $12,000, and a flooded finished basement often lands between $3,000 and $15,000. Water depth, how long it sat, salt residue, and how much drywall, flooring and contents must go all move the price. General market ranges, not quotes.
How Long It Takes
Once the water is out and soaked materials are removed, drying usually takes 3 to 5 days, longer in a cold or very humid basement. Rebuilding drywall, flooring and trim often adds 1 to 3 weeks depending on how much had to come out.
Call (203) 555-0163Floodwater Got Into the House in Connecticut
Floodwater reaches Connecticut homes from the Sound, from rivers and from sudden storms. In Fairfield County, Sandy pushed a surge of more than 9 ft into the Bridgeport gauge and a house floated away in Fairfield. In New Haven County, the August 2024 flash floods brought 12 to 16 in of rain to Oxford and washed out a bridge in a Southbury state park, while Irene had already washed away shoreline homes in East Haven. In Litchfield County, Winsted and Torrington were among the hardest hit in the August 1955 flood. Older housing across the state means many basements were never built with floods in mind.

Floodwater Got Into the House FAQs
How do I clean up floodwater in my basement?
Start with safety: power off in the wet area, no wading, and gloves and boots if you must go near it. Floodwater is category 3, so soaked carpet, insulation and lower drywall usually need to be removed and the space cleaned before drying, which is work a local crew is set up for.
Can I stay in my house after floodwater came in?
It depends on how much of the house got wet, whether the power and heat are safe, and whether sewage came in with the water. If only the basement flooded and upstairs is dry and powered safely, many people stay while the crew works.
Do I have to throw out drywall after a flood?
Drywall that floodwater touched is usually cut out above the wet line, because it soaks up contaminated water and cannot be cleaned inside. Walls that only got damp from humidity can sometimes be dried in place after meter readings.
How soon should flood cleanup start?
As soon as it is safe to enter. EPA guidance says mold usually will not grow if wet materials are dried within 24 to 48 hours, but that guideline is for clean water, and floodwater adds contamination on top.
Is salt water from a coastal storm worse than rain water?
Salt water leaves residue on wood, concrete and wiring that keeps pulling in moisture and speeds corrosion. Shoreline floods need a thorough rinse and cleaning before drying, in addition to the steps used for any floodwater.
