First: Is It Safe to Go Down There?
An electric sump pump stops when the power fails, which is why FEMA recommends a battery-operated backup. If the pump has stopped, the water may keep rising while you are working out what to do.
Where Is the Water Coming From?
Basement water has a handful of usual entry points. Knowing which one you have tells you what to check and what to tell a professional.
- The sump pit. FEMA describes sump pumps as drawing in groundwater from around the house and directing it away through drainage pipes. Saturated ground can fill the pit faster than the pump moves water, and a pump that fails or loses power does not move any.
- Foundation walls and the floor. FEMA recommends closing foundation cracks and sealing basement walls with waterproofing compounds to avoid seepage.
- Floor drains. A floor drain that backs up can mean sewer water, which is a different, more contaminated problem. FEMA recommends drain plugs and sewer backflow valves installed by a qualified, licensed plumber.
- Outside water running toward the house. Roof runoff and meltwater that drain toward the foundation instead of away from it.
If the water is coming from a floor drain, treat it as possible sewage and see EPA’s advice on sewage backups: avoid contact and contact your local health department or regulatory agency.
What to Check Once It Is Safe
FEMA’s guide to low-cost home flood protection lists simple checks that apply directly to a basement that takes on water at thaw (FEMA).
- Clean gutters, downspouts and splashpads so roof water flows away from the house.
- Clear snow and ice away from the foundation.
- Look at how water flows around the house. Stormwater should drain away from the building.
- Make sure floor drains are clear of obstructions.
- If you have a sump pump, choose one with a battery-operated backup in case of power failure.
FEMA also says flood protection measures need to be tailored to the property and may need advice from local engineers or contractors, and that some changes need permits. Check with your local building department before changing drainage.
Remove the Water, Then Dry the Structure
Before anything is moved or thrown away, take photos or video when that is practical. The NYS Department of Health lists documentation for insurance as part of cleanup.
When water is widespread, NYS Homeland Security and Emergency Services advises draining a flooded basement in stages after the surrounding water has subsided. Draining it all at once can load the foundation unevenly, which is a structural question for a professional.
Wet materials hold moisture after the standing water is gone. EPA advises drying water-damaged areas and items within 24–48 hours where possible, because damp materials that dry in that window usually do not grow mold. That is a target worth working toward. It is not a promise that mold cannot grow, and it is not a deadline after which mold appears.
If mold turns up
On a New York mold project, H&H performs either the mold assessment or the mold remediation — never both on the same project. See mold services.
What H&H Does on a Wet-Basement Call
H&H Environmental has operated since 2005. For a wet basement, the work falls into these parts. Each is described as a service, not a promise about timing, because every basement is different.
Water extraction. Standing water is removed. (Emergency water extraction)
Removal of wet or damaged materials, where necessary. Materials that cannot be dried are taken out so they do not keep moisture against the structure.
Structural drying and dehumidification. The structure and the air are dried. (Structural drying)
Antimicrobial treatment. Used where it is appropriate.
Monitoring. Drying is monitored so the work continues until the structure is dry.
Documentation and insurance. We work directly with your insurance carrier and provide documentation and direct billing for covered losses. Whether a loss is covered is decided by your policy and your carrier, not by H&H. (Insurance help)
Sump pumps, drainage and foundation sealing are separate trades from the water damage services above. The full list of what we do is on the water damage restoration page.
