In the first hour after a basement flood, stay out of standing water, keep children and pets away, and call for help. Stop a plumbing leak only if you can reach the shutoff from a safe, dry location. Document visible damage without entering the flooded area, then arrange professional water removal and drying.
Discovering water in your basement can leave you wondering what to do first. Should you check the sump pump, move furniture, or call a restoration company? Before taking action, you need to consider electrical hazards, possible contamination, and where the water is coming from.
For homeowners in Mentor, Painesville, Willoughby, Eastlake, and nearby Lake County communities, the first hour is about protecting people and arranging the right help. This guide explains the steps you can take without putting yourself at risk.

Your First-Hour Basement Flood Checklist
You do not need to start removing water yourself to make progress. Use this checklist to organize your next steps, and skip any action that would require entering an unsafe area.
- First 5 minutes: Keep people away from the basement and check for hazards from a dry location.
- 5–15 minutes: Call for help and stop a plumbing leak only if the shutoff is safely accessible.
- 15–30 minutes: Photograph visible damage and notify your insurer or landlord.
- 30–60 minutes: Prepare information for the cleanup crew and keep access to your home clear.
First 5 Minutes: Stay Out of the Water
Do not enter a flooded basement to inspect the damage. Standing water can hide electrical hazards, sharp debris, and contamination. A shallow water level does not mean the basement is safe, and rubber boots do not protect you from every electrical hazard.
Keep children and pets away from the basement entrance. If you smell gas, see sparks, or suspect structural damage, leave the building and call 911 or the appropriate utility from a safe location. Do not operate switches or electrical equipment where gas may be present.
If your main electrical shutoff is inside the flooded basement, do not walk through water to reach it. Contact the utility or a qualified electrician for help. The CDC’s flooded-home safety guidance explains the hazards homeowners should consider before entering an affected space.
5–15 Minutes: Call for Help and Address the Water Source
Stop an active plumbing leak only if you can reach the water shutoff from a safe, dry location. If a broken supply line caused the flooding, a plumber can repair the source while a restoration company addresses the resulting damage.
Other sources may be harder to identify. Water can enter through foundation openings, collect around a failed sump pump, or back up through a floor drain. Tell the responding team what you can see without approaching the water.
- Your address and the affected area of the home
- When you first noticed the water
- Whether the water level appears to be rising
- Any visible plumbing leak, sump pump issue, or drain backup
- Whether electrical equipment or outlets may be affected
If you do not know the source, say so. Clear-looking water can still contain contaminants. Avoid contact with sewage, drain backups, and outdoor floodwater.

15–30 Minutes: Document the Damage From a Safe Location
Take photos or video before cleanup changes the scene, but do not enter the flooded area to get them. From a dry location, capture the visible water level, affected rooms, and damaged belongings when possible.
Write down when you discovered the flooding and what you noticed first. Keep records of calls, emergency services, and related expenses. These details can help the restoration team understand the situation and support your insurance documentation.
- Photos of visible damage taken from a safe location
- A list of affected belongings
- The time you discovered the water
- Notes about the suspected source
- Receipts for emergency repairs and cleanup
Notify your insurer and ask what documentation it needs. Coverage depends on the cause of the damage and your policy. A plumbing leak, groundwater intrusion, and sewer backup may receive different treatment, so avoid assuming the cleanup will be covered.
If you rent your home, notify your landlord or property manager.
30–60 Minutes: Prepare for the Restoration Crew
Keep access clear and give the crew the information it needs to assess the basement. Explain any known electrical hazards, possible sewage contamination, or areas that may be difficult to reach.
Move belongings only if they are outside the affected area and safe to handle. Do not enter standing water to rescue furniture, storage boxes, or electronics. Let the responding professionals determine when entry is safe.
If someone in your household needs help staying away from the basement, arrange a safe place for them while the crew works. Keep pets secured and leave a clear route to the home.
What Not to Do After a Basement Flood
Some common cleanup attempts can create additional hazards or spread contamination. Before plugging in equipment or removing materials, wait for an assessment.
- Do not use a household vacuum to remove water. Standard vacuums are not designed for water extraction.
- Do not plug in fans or other equipment before electrical safety is confirmed. Wet outlets and equipment can present serious hazards.
- Do not run fans over sewage or suspected contamination. Ask the restoration team about containment and cleanup first.
- Do not start cutting drywall or pulling up flooring. Professionals should assess contamination and material hazards before demolition.
- Do not rush to pump out deep floodwater. Get professional guidance, especially while outdoor water remains high.
What Happens After the First Hour?
Professional cleanup begins with a safety and damage assessment, followed by appropriate water removal and drying. The restoration team evaluates the source, affected materials, and moisture beyond the visible standing water.
Water can remain inside walls, beneath flooring, and within insulation after the surface looks dry. Moisture detection and monitoring help the crew determine where drying is needed and when drying goals have been met.
Some materials may need removal, while others may be candidates for cleaning and drying. The approach depends on the water source, contamination, material condition, and extent of damage.
Federal guidance recommends cleaning and drying a flooded home within 24–48 hours when possible to reduce mold risk. That is a reason to arrange help promptly, not a reason to enter an unsafe basement. See the CDC’s disaster cleanup guidance for more information.

Frequently Asked Questions About Basement Flooding
Can I enter my basement if there are only a few inches of water?
No. Shallow water alone does not establish that entry is safe. Electrical equipment, contamination, and hidden hazards can still make the basement dangerous. Wait for a qualified professional to assess it.
Should I call a plumber or a restoration company?
You may need both. A plumber addresses plumbing failures, while a restoration company assesses and cleans up the water damage. Explain the suspected source when you call so the right help can respond.
