Water Emergency in Your House? What to Do Right Now
If water is actively entering your house, focus first on people, electricity, the water source, and preventing additional damage. The right response depends on whether you have a burst pipe, sewage backup, roof leak, overflowing fixture, leaking appliance, or another source of water.
Water + electricity can be dangerous. Do not walk through standing water to reach an electrical panel or electrical equipment. If electrical conditions appear unsafe, stay out and contact qualified emergency or utility personnel.
What should you do first when water is entering your house?
Your first goal is not to start repairing drywall or worrying about paint. It is to make the situation safe, stop additional water when possible, determine where the water is coming from, and prevent the loss from getting larger.
Check for Immediate Danger
Look for electrical hazards, sagging or collapsing ceilings, structural damage, sewage, hot water, gas odors, fire, or other unsafe conditions.
Find the Water Source
Determine whether the water is coming from plumbing, a toilet, appliance, water heater, roof, sewer, basement, or another source.
Stop the Water if Safe
Use a fixture shutoff or the home's main water shutoff when appropriate and when you can reach and operate it safely.
Protect Unaffected Property
Move furniture, electronics, rugs, boxes, and other belongings away from spreading water when doing so does not expose you to a hazard.
Take Photos & Video
Once immediate safety is addressed, document the apparent source, standing water, affected materials, and damaged belongings when practical.
Address Cleanup & Drying
Once the source is controlled, determine how far the water traveled and what needs water removal, drying, cleaning, or professional attention.
Should you shut off the water?
If the emergency is caused by pressurized household plumbing, stopping the water can prevent substantial additional damage. Depending on the source, you may be able to use a local fixture valve or the home's main water shutoff.
Examples where shutting off water may help
- A burst or broken supply pipe.
- A failed toilet supply connection.
- A leaking sink or plumbing fixture.
- A failed appliance supply hose.
- Certain water-heater plumbing leaks.
Home shutoff locations vary. If you do not know how your system works, do not damage plumbing components or enter an unsafe area trying to improvise during an emergency.
When shutting off the house water will not solve the source
The main water shutoff will not stop every type of water emergency. Roof leaks, groundwater, exterior flooding, sewer backups, and some drainage problems require different responses.
What if water is near electrical outlets or equipment?
Water emergencies can create electrical hazards when water reaches outlets, wiring, appliances, electrical equipment, or energized areas. Standing water can also conceal an electrical hazard.
If reaching a breaker panel or electrical equipment would require entering standing water or another unsafe area, stay out. Contact qualified emergency, utility, or electrical personnel as appropriate.
Be especially cautious when:
- Water is near outlets, extension cords, or electrical equipment.
- Water is entering through light fixtures or ceiling electrical boxes.
- Standing water is present around appliances.
- The electrical panel or its surrounding area is wet.
- You hear buzzing, see sparks, or smell burning.
If water is coming through your ceiling, stay away from affected light fixtures and visibly unstable ceiling areas.
What if the ceiling is sagging or filling with water?
Water above a ceiling can saturate drywall, insulation, and other materials. A ceiling that is visibly sagging, bulging, cracking, or deteriorating may present a falling-material hazard.
If the ceiling appears unstable:
- Keep people and pets out of the area beneath it.
- Do not stand directly underneath a bulge or sag.
- Stay away from wet light fixtures and electrical components.
- Address the source from a safe location when possible.
- Get qualified help when the condition appears unsafe.
Opening a bulging ceiling can release water and damaged material suddenly and may expose electrical or structural hazards. An unstable ceiling should be treated cautiously.
See our complete Water Coming Through the Ceiling Guide.
What if the water is sewage?
Sewage is not an ordinary water spill. It can contain microorganisms and other contaminants, and the cleanup approach can differ substantially from a small clean-water plumbing leak.
If sewage is entering the house:
- Keep children and pets away from the affected area.
- Avoid direct skin contact with sewage or contaminated materials.
- Stop using plumbing fixtures if doing so may worsen the backup.
- Consider whether electrical hazards are also present.
- Address the sewer, drain, or septic source.
- Use appropriate cleanup precautions and professional assistance when warranted.
Contamination affects personal protection, cleaning, disinfection, and decisions about porous materials that were exposed.
Continue to our Sewage Backup in the House Guide for more detailed information.
What if the water is coming from the water heater?
A leaking water heater can involve hot water, electricity, gas controls, pressurized plumbing, and a potentially large volume of water. The exact response depends on the type of heater and where the leak is occurring.
Look for the apparent leak location
- Water connections at the top of the unit.
- The drain valve.
- The temperature-and-pressure relief system.
- The tank body or bottom of the unit.
- A nearby pipe or another source that only appears to be the heater.
If you smell gas or suspect a gas leak, leave the area and follow appropriate emergency and utility procedures rather than continuing to troubleshoot the water heater.
See our complete Water Heater Leaking Guide.
What if rain is coming through the roof?
During an active storm, the priority is protecting people and limiting interior damage without creating a second emergency.
Roof leaks can travel along framing, decking, insulation, and other materials before becoming visible on a ceiling. The location of the interior drip may not be directly beneath the exterior roof problem.
During an active roof leak:
- Keep away from unstable or sagging ceilings.
- Move belongings away from dripping water when safe.
- Use containers for accessible drips when doing so is safe.
- Document interior damage.
- Do not climb onto a wet, icy, storm-damaged, or otherwise unsafe roof.
Water can travel before it becomes visible, so identifying the actual roof defect may require inspection after conditions are safe.
Continue to our Roof Leak Water Damage Guide.
The leak stopped. Are you finished?
Not necessarily. Once the source is controlled, the next question is where the water traveled and what remains wet.
Water can move beneath flooring, behind baseboards, into wall cavities, through ceilings, inside insulation, and beneath cabinets. A room can look substantially better after the puddle is gone while concealed materials remain wet.
Check beyond the visible water
- Adjacent rooms.
- The floor below the leak.
- Baseboards and lower drywall.
- Carpet padding and subflooring.
- Cabinet bases.
- Wall and ceiling cavities.
- Insulation.

What to do—and what not to do—during a water emergency
Do
- Put personal safety first.
- Identify the water source when possible.
- Stop additional water when it can be done safely.
- Keep people and pets away from contaminated water.
- Move unaffected belongings when safe.
- Document the source and damage when practical.
- Check nearby rooms and lower floors.
- Begin appropriate water removal and drying promptly.
- Keep receipts, estimates, and repair records.
Don't
- Enter standing water when electrical hazards may be present.
- Stand beneath a visibly unstable or sagging ceiling.
- Treat sewage as ordinary clean water.
- Climb onto an unsafe wet or storm-damaged roof.
- Ignore water because the visible puddle disappeared.
- Assume hidden walls and floors are dry.
- Cover wet materials with new finishes before the moisture problem is addressed.
- Throw away major damaged property before documenting it when documentation can safely be completed first.
What should you document during a water emergency?
Once immediate safety concerns are addressed, documentation can help establish what happened, what property was affected, and what emergency work was necessary.
- The apparent source of the water.
- Photos or video of standing or actively leaking water.
- Damaged flooring, walls, ceilings, cabinets, and belongings.
- The date and approximate time you discovered the loss.
- Emergency plumbing or source-repair work.
- Water removal and drying services.
- Receipts and invoices.
- Repair estimates.
Photos can be useful, but they are not worth entering an unsafe flooded, contaminated, electrically hazardous, or structurally unstable area.
Coverage depends on your policy and the cause of the loss. See our Water Damage Insurance Guide for more information.
When should you call a professional for water damage?
A small, accessible clean-water spill can be very different from a major water loss. Professional assistance becomes more important as the size, hazards, contamination, and complexity increase.
Consider professional help when:
- There is significant standing water.
- Water is continuing to enter and you cannot stop the source.
- Sewage or contaminated water is involved.
- Multiple rooms or floors are affected.
- Water entered walls, ceilings, insulation, or subflooring.
- Electrical or structural hazards may exist.
- The ceiling is sagging or damaged.
- You cannot determine where the water traveled.
- The area has remained wet for an extended or unknown period.
- Mold is visible or suspected.
Different emergencies may require different professionals. A plumber, roofer, sewer professional, electrician, utility, restoration company, or other qualified provider may be appropriate depending on the source and conditions.
Water emergency FAQ
What is the first thing to do when water is flooding your house?
Check for immediate hazards and protect people first. Then identify and stop the water source when it can be done safely. Once the source is controlled, address standing water, document the damage, and begin appropriate cleanup and drying.
Should I turn off the main water if my house is flooding?
If household plumbing is the source, shutting off the appropriate fixture valve or main water supply can help stop additional water. It will not stop every type of emergency, including roof leaks, exterior flooding, groundwater, or sewer backups.
Is it safe to walk through standing water in my house?
Do not enter standing water when electrical hazards, sewage, structural damage, or other dangerous conditions may be present. If the area may be unsafe, stay out and seek qualified assistance.
What if water is coming through a light fixture?
Stay away from the wet fixture and affected area because water and electrical components can create a serious hazard. Do not stand in water or beneath an unstable ceiling to reach electrical equipment.
Should I puncture a ceiling that is bulging with water?
A visibly sagging or water-filled ceiling can be unstable and may also involve electrical hazards. Do not casually stand beneath it and puncture it. Keep people away and obtain qualified help when needed.
What if sewage is flooding the house?
Keep people and pets away from the contaminated area, avoid direct contact, stop using plumbing when additional use may worsen the backup, address the source, and use appropriate sewage-cleanup precautions.
Should I call insurance before a water restoration company?
Claim procedures vary, but an active emergency should not simply be allowed to worsen while waiting. Address immediate safety and reasonable steps needed to limit additional damage, document conditions when practical, keep records, and follow your policy and insurer's applicable reporting requirements.
What should I do after the visible water is gone?
Determine whether water entered flooring, drywall, insulation, ceilings, cabinets, or other concealed areas. Removing the visible puddle does not necessarily mean the structure is dry.
What is causing the water emergency?
Emergency controlled? Now figure out what is still wet.
Once the source is stopped and the area is safe, the next job is determining how far the water traveled, what materials were affected, and what needs cleanup, drying, or repair.
