Water is flooding your house — what to do right now

This article is for educational purposes only and is not a substitute for professional advice. Local codes, regulations, and best practices vary by region.

Water is pouring into your house. It’s coming from somewhere. It’s getting everywhere. You have a few minutes to make decisions that determine whether this is a controlled emergency or total disaster. The first thing to do is stop panicking and do the things that matter right now. Everything else can wait a few minutes.

This is an emergency but not unmanageable. Water damage is repairable. Properties recover from flooding. Your job right now is to minimize damage and prevent it from getting worse. Panicking doesn’t help. Clear thinking does. Here are your priorities.

Step One: Stop the Water

The first thing is to find the source and stop it if possible. If water is pouring in from outside (rain coming through walls or windows), close doors and windows. If the problem is a burst pipe, locate your main water shutoff and turn it off. The shutoff is usually near the water meter or where the main line enters your house. Know where yours is before you need it in an emergency. If you don’t know, find it now.

If you can identify the source and safely stop it, do that. If you can’t locate the shutoff or the water is coming from outside faster than you can control it, move to step two.

Step Two: Protect People and Critical Items

Move people away from the water. If electricity is involved (water near outlets, panels, or appliances), turn off the main breaker. Wet electrical systems are dangerous. If water is entering from an electrical source, do not touch it.

Grab critical items—documents, photos, irreplaceable things—and move them to high ground. Laptops, hard drives, photos, and important papers should be moved to a dry location immediately. Don’t spend time on everything, just the irreplaceable things.

Shut doors to contain flooding if you can. This limits spread to unaffected areas.

Step Three: Call for Help

Once the water is stopped or contained, call for professional help. For major flooding, call a water damage company. These companies have industrial equipment that extracts water, dries structures, and prevents mold. Cost is significant—often $1,000-5,000+ depending on area affected—but it prevents exponentially worse problems. Water damage companies usually respond quickly.

For plumbing emergencies (burst pipes inside), call an emergency plumber. Cost for emergency service is higher than regular plumbing but necessary.

For natural disasters (flooding from outside, storms), contact your insurance company if you have it. They have preferred contractors and can authorize repairs. If you don’t have flood insurance and flooding came from outside, you have limited coverage, but your homeowner’s insurance might cover some damage.

Document damage. Take photos of wet areas, water lines, and affected items before cleanup begins. This helps with insurance claims.

Assessing Severity

How much water are we talking about? A few inches in your basement is serious but different from water throughout your house. Water that stays contained in one area is different from water spreading everywhere.

Is water from inside your house (burst pipe, plumbing issue) or from outside (flooding, storm)? Inside water is typically cleaner and requires less cleanup concern. Outside water is contaminated and requires more aggressive drying and cleaning.

Is the water still entering or has it stopped? If stopped, damage is contained. If continuing, you’re still in crisis mode.

Has electricity been affected? Wet electrical systems are dangerous and require professional assessment before you restore power.

These factors determine how quickly you need help and how much you’ll need. If water is still entering or if electrical systems are affected, treat this as urgent. If water has stopped and is contained, you have more time to organize professional help.

What Not to Do

Don’t go wading through flood water if you don’t have to. It’s contaminated with sewage, chemicals, and debris. Wear boots if you must go through it.

Don’t use household vacuum cleaners to extract water. You’ll damage the vacuum and potentially electrocute yourself if there’s any electrical involvement.

Don’t turn on major appliances or use outlets in wet areas. Water and electricity are a dangerous combination.

Don’t attempt structural drying yourself. Water gets into walls, under floors, and in cavities where you can’t reach it. Professional equipment dries these areas. Without it, mold develops.

Don’t delay professional water removal thinking you’ll handle it yourself. The first 24-48 hours are critical. The longer water sits, the more damage and mold growth happens.

Immediate Temporary Measures

While waiting for professional help, open windows if weather allows and run fans to move air. This helps with initial drying but doesn’t replace professional equipment. Air circulation does help prevent mold in that first day.

Mop up standing water with towels and a wet vacuum if you have one. Removing water from surface areas helps. Move furniture to high ground if possible to prevent it absorbing water.

Turn off the water heater if water flooded that area. Damaged water heaters are a safety issue.

If electricity is secure (no water near outlets), turn on dehumidifiers to extract moisture from air. This helps prevent mold but again, professional drying is necessary.

Professional Water Extraction

Professional water removal uses industrial pumps and vacuums that extract water from structures and can handle large volumes quickly. Drying involves dehumidifiers and air movers that run for days to dry walls, floors, and cavities.

The goal is to reduce moisture below the level where mold can grow. This takes professional equipment and expertise. Cost ranges from $1,000 for minor incidents to $10,000+ for severe flooding. Insurance sometimes covers this if water came from covered events (burst pipes from freezing, for example), but policies vary widely.

After Water is Removed

Once professionals extract standing water, the real work begins—drying. This takes days or weeks. Dehumidifiers and air movers run continuously. Doors and windows open for ventilation. Flooring might need removal for walls to dry. Insulation in walls might need replacement if saturated.

Mold prevention becomes critical. Any damp material should be removed if it can’t dry completely in 24-48 hours. Drywall, carpet, and insulation that remain damp will develop mold. Prevention is cheaper than mold remediation later.

Documenting everything—photos of damage, receipts for cleanup costs, records of professional work—helps with insurance claims. Keep detailed records.

Insurance and Recovery

Contact your insurance company immediately. They need to know about the damage for claims. Some damage is covered, some isn’t (flood damage is typically not covered by standard homeowner’s insurance unless you have a separate flood policy). Document the situation fully.

Recovery from water damage is possible but expensive. The sooner you address it, the less expensive it becomes. Immediate professional intervention prevents secondary damage (mold, structural rot) that costs far more to fix than the original water removal.

The Bottom Line

A water emergency requires immediate action to stop water entry and protect people and belongings. Call professional help immediately. Water damage is repairable but the first 24-48 hours are critical. Professional water extraction and drying prevent mold and structural damage. Quick response turns a flood into an expensive repair. Delayed response turns a flood into a disaster. Act now, worry about costs later—it’s the right priority.
