A flooded home hits you all at once, the shock, the mess, the "what now?" Standing in inches of water with belongings soaking around you, knowing what to do after home floods is the difference between a manageable recovery and months of compounding problems. Every minute counts, because water keeps causing damage long after the initial event ends.


The good news: there's a clear path forward. You need to protect yourself first, then your property, then deal with insurance, in that order. Skipping steps or handling them out of sequence can put your health at risk or cost you thousands in denied claims. Most homeowners have never dealt with a flood before, so the process feels overwhelming when it shouldn't have to be.


This guide walks you through exactly what to do from the moment floodwaters enter your home through final restoration. At Water Damage Repair Tech, we've helped homeowners across Austin and surrounding communities recover from floods, burst pipes, and storm damage with 24/7 emergency response. We built this guide from that hands-on experience, so you'll get practical, proven steps rather than generic advice.


Before you start: safety checks and water type


Before you do anything else, assess the situation from a distance. Entering a flooded space without checking for hazards first can turn a property emergency into a personal one. You need to know two things before stepping inside: whether the environment is physically safe, and what type of water caused the flooding, because that changes how you approach cleanup and what protective gear you need.


Know the water category first


Not all floodwater carries the same risk, and knowing what you're dealing with tells you how cautious to be. Category 1 (clean water) comes from a supply line break, a leaking appliance, or rainwater entering directly, it poses the least immediate health risk. Category 2 (gray water) includes overflow from washing machines or dishwashers and contains low-level contaminants and microorganisms. Category 3, called black water, is the most dangerous: sewage backups, outdoor floodwater, and any standing water that has sat for more than 48 hours. Even clean water escalates to Category 3 after two days of sitting.


If your flood came from an external storm or a river, treat all water as Category 3 regardless of how it looks or smells.

Check for hidden hazards before you enter


Electrical and gas hazards cause more flood-related injuries than the water itself. Before you walk into any flooded area, go to your electrical panel and shut off power to every affected circuit if you can reach the panel without standing in water. If the panel is in the flooded zone or you're uncertain, call your utility company to disconnect service from the outside. For gas, if you smell anything or hear hissing near lines, leave immediately and call your gas provider.


Structural checks come next. Swollen door frames, cracks running along exterior walls, or a visibly sagging ceiling all signal that the building may be compromised. If you spot any of those warning signs, stay out and call a restoration professional before you proceed. Knowing what to do after home floods starts with protecting yourself, because no amount of property damage is worth entering a structurally unsound or electrically live space.


Step 1. Make it safe and stop more damage


Once you've confirmed it's safe to enter, your first priority is stopping the water at its source and preventing further damage to everything still intact. If you know what to do after home floods, you know that acting within the first hour dramatically limits the total repair bill. Move fast, but work methodically, because rushing without a plan leads to missed steps.


Shut off the water source


If your flood came from a plumbing failure, find your main water shutoff valve and close it immediately. In most Austin-area homes, this valve sits near the front of the house along the foundation, in a utility closet, or under the kitchen sink. Turning it clockwise shuts off supply to the entire home. If you can't locate the main shutoff, go to the street and use the meter shutoff, which requires a meter key or an adjustable wrench available at most hardware stores.


If a storm or external source caused the flooding, you can't stop the source, so focus all your energy on protecting the interior from that point forward.

Protect undamaged belongings


Move furniture, electronics, and valuablesto the highest dry floor in your home as quickly as possible. Place aluminum foil or wooden blocks under furniture legs that can't be moved, which slows water absorption into the wood and reduces permanent staining. Take photos of everything before you move it, since that documentation directly supports your insurance claim in the next step.


Limit how many people walk through the flooded area. Each person tracking through wet rooms spreads contamination and drives water further into subfloor materials. Keep the path of movement short and direct, and have clean footwear ready at the exit point so you don't carry contaminated water into dry areas of the home.


Step 2. Document damage and start your claim


Documentation is the foundation of any successful insurance claim. Before you remove a single soaked item or pull up damaged flooring, capture evidence of everything the flood touched. Insurance adjusters work from the record you create, so gaps in your documentation can directly reduce your payout. Knowing what to do after home floods means treating your phone like a job site camera from this point forward.


Photograph and record everything


Start at the water's entry point and work outward room by room. Take overlapping photos and short video clips at floor level, mid-wall, and ceiling height so the adjuster sees the full vertical scope of damage. For each room, capture wide shots showing the overall space and close-ups of specific damage like waterlogged drywall, buckled flooring, or ruined appliances. Write the date and time on a notepad and photograph it at the start of each room's documentation session.


Use this checklist to make sure you capture everything before you start removing anything:


  • Structural damage: walls, floors, ceilings, doors, windows

  • Damaged contents: furniture, appliances, electronics, clothing

  • Water entry points: broken pipes, wall gaps, foundation cracks

  • Any mold or discoloration already visible


File your claim the right way


Call your insurance company as soon as you finish documenting, not before, so you can answer their questions with accurate information. Most policies require you to report damage within a specific window, often 24 to 72 hours, so check your policy terms immediately.


Keep a backup of all photos and videos in cloud storage before submitting anything to your insurer.

Give the adjuster your complete photo and video files along with a written inventory of every damaged item, including estimated values where possible. A thorough submission speeds up the adjuster's review and reduces the chance of a low-ball settlement.


Step 3. Remove water and dry the home fast


Standing water is actively destroying your home every hour it sits. Flooring, subfloor, drywall, and framing absorb moisture continuously, and mold can begin growing within 24 to 48 hours. Knowing what to do after home floods means treating water removal as an emergency task, not something to start after you've finished documenting.


Extract standing water first


Your extraction method depends on how much water you're dealing with. Wet/dry vacuums handle small volumes well and are available at most hardware stores for under $100. For anything more than an inch of standing water, a submersible pump moves water faster and connects to a garden hose so you can direct discharge well away from your foundation.


Discharge pumped water at least 20 feet from your foundation and away from neighboring properties to prevent it from seeping back through the soil.

If you're dealing with Category 3 water, avoid direct contact during removal and use a professional-grade pump rather than a shop vac, since contaminated water can aerosolize during suction and create a serious health hazard.


Set up drying equipment the right way


Once standing water is out, air movement and dehumidification do the heavy lifting. Position fans to push air across wet surfaces, not just into the room, and place a commercial dehumidifier in the center of each affected room. Run equipment continuously for at least 72 hours and use an inexpensive moisture meter to confirm materials are actually drying, not just feeling dry on the surface.


Use this checklist to set up your drying station correctly:


  • Run fans continuously, pointing directly at wet walls and floors

  • Empty dehumidifier reservoirs every few hours or connect to a drain line

  • Open interior doors to allow air circulation between rooms

  • Check moisture meter readings every 12 hours to track progress

  • Keep windows closed if outdoor humidity is above 60%


Step 4. Clean, disinfect, and prevent mold


Drying removes moisture, but it doesn't remove the bacteria and pathogens that floodwater deposits on every surface it touches. Cleaning and disinfecting is a separate step that most homeowners skip or rush, and that mistake leads to mold growth and persistent odor weeks later. This is where what to do after home floods comes down to thoroughness: every surface that water contacted needs to be cleaned before you close up the space.


Disinfect all affected surfaces


Start by removing any material that can't be fully dried and cleaned, including drywall soaked more than an inch above the waterline, carpet padding, and particle board furniture. These materials trap moisture and bacteria even after the surface feels dry, making them a guaranteed source of mold if left in place. Wipe down all hard surfaces, including concrete, tile, studs, and subfloor, with a cleaning solution before applying disinfectant.


Use this disinfection protocol on all hard, non-porous surfaces after cleaning:


  • Mix 1 cup of unscented liquid bleach per gallon of water

  • Apply with a sponge or pump sprayer and let sit for at least 10 minutes

  • Wipe away and allow to air dry completely before any reconstruction begins

  • Wear gloves, eye protection, and an N95 mask throughout this process


Stop mold before it starts


Mold spores are already present in most indoor environments; standing moisture is the only thing they need to start colonizing. After disinfecting, keep fans and dehumidifiers running for an additional 48 hours and use your moisture meter to confirm readings below 16% in wood materials.


If you spot any fuzzy growth, discoloration, or persistent musty odor, stop work and call a certified mold remediation professional immediately before it spreads further.

Check inside wall cavities by removing a small section of baseboard trim. Hidden moisture between the drywall and framing is the most common cause of mold problems that don't show up until weeks after a flood.


Next steps after cleanup


Once cleaning and drying are complete, your home still needs structural assessment before reconstruction begins. Hire a licensed contractor to inspect framing, subfloor, and any wall cavities you opened during cleanup. This inspection catches hidden moisture pockets or weakened structural elements that photos and moisture meters can miss. Get the assessment in writing so you have documentation to submit alongside your insurance claim before any rebuild work starts.


Knowing what to do after home floods gets you through the immediate crisis, but the recovery process extends into the weeks that follow. Review your insurance policy for replacement cost versus actual cash value coverage, since that distinction affects how much you receive for damaged belongings and materials. Report any supplemental damage you discover during reconstruction to your adjuster promptly.
