TL;DR: Get everyone out safely and cut the power. Don't wade into standing water until you know it's safe. Photograph everything before touching it. Call your insurer and a licensed Dallas water damage cleanup company immediately — the faster you act, the less damage you'll face.
A house flood is one of the most disorienting emergencies a homeowner can face. One moment everything is normal; the next, you're watching water creep across your floors and you have no idea what to do first. In Dallas, where intense thunderstorms can drop several inches of rain in just a few hours and aging pipes can fail without warning, flooding happens more often than most people expect.
This guide walks you through exactly what to do — in the right order — so you protect your family, minimize property damage, and give yourself the best chance at a full insurance payout.
Step 1: Get Everyone Out Safely
Before anything else, your only priority is the safety of the people (and pets) in your home. Floodwater is deceptive — it doesn't look dangerous, but it can be.
- Evacuate immediately if water is rising quickly, the structure feels unstable, or you smell gas.
- Don't walk through moving water. Just six inches of moving water can knock a person off their feet.
- Watch for electrical hazards. If your home has standing water near electrical outlets, appliances, or your breaker panel, assume the power is live until proven otherwise.
- Shut off electricity at the main breaker if you can do so without standing in water. If you can't reach the panel safely, call your utility company — Oncor in most of Dallas — to shut off power from outside.
- Avoid sewage-contaminated water (it has a distinctive foul odor). It carries serious pathogens. If you suspect sewage backup is involved, you need professional sewage cleanup — do not attempt this yourself.
Step 2: Stop the Source If You Can
If the flooding is coming from inside your home — a burst pipe, a failed water heater, an overflowing appliance — shut off the water supply immediately. Every second counts when water is actively flowing into your home.
- Know where your main shutoff valve is before an emergency happens. In Dallas homes it's typically near the water meter, often on the side of the house or in the garage.
- If a single fixture is the source (like a toilet that overflowed), shut off the local valve at the base of that fixture.
- For a burst pipe, shut off the main valve and call a plumber alongside your water damage restoration team.
If the flooding is from outside — storm runoff, a rising creek, or street flooding coming in through a door or window — you can't stop the source, but you may be able to slow it. Sandbags, rolled-up towels along door thresholds, or plastic sheeting can buy you a few minutes while you evacuate valuables to higher ground.
Step 3: Document Everything Before You Touch It
This step feels counterintuitive when you just want to start cleaning up, but it's critical for your insurance claim. Insurance adjusters need to see the damage as it was — not after you've moved things around.
- Take photos and video of every affected room from multiple angles. Get close-ups of waterlines on walls, damaged flooring, furniture, and appliances.
- Photograph the source of the flooding if visible (the broken pipe, the point where water entered).
- Make a written inventory of every item that was damaged, including approximate purchase dates and values.
- Save any receipts for emergency purchases (hotel stays, emergency plumbing repairs, etc.) — these are often reimbursable.
- Don't throw anything away yet, even damaged items. Your adjuster may want to inspect them in person.
Step 4: Call Your Insurance Company
After documenting the scene, call your insurance company to open a claim as soon as possible. Keep these things in mind:
- Standard homeowner's insurance covers sudden, accidental water damage — burst pipes, appliance failures, roof leaks from a storm. It does not cover rising water from outside (flooding from storms, overflowing rivers).
- Flood insurance (through the National Flood Insurance Program or a private insurer) covers water that originates from outside your home. If you're in a Dallas flood zone and don't have this coverage, you may be paying out of pocket.
- Ask your insurance company whether you're covered for additional living expenses (ALE), which pays for hotel costs while your home is being restored.
- Get a claim number and the name of your adjuster. Write it down.
Step 5: Start Water Removal Immediately
Standing water is a ticking clock. The longer it sits, the deeper it penetrates into flooring, subfloors, wall cavities, and insulation — and the faster mold takes hold. In Dallas's warm climate, mold can begin growing within 24 to 48 hours of water exposure.
For significant flooding, this is where you call a professional water extraction service. A licensed restoration company will use truck-mounted or portable extractors that remove hundreds of gallons per hour — far more than any shop vac or consumer pump can manage.
If the water level is very low and you're waiting for help to arrive, you can begin removing water with mops, towels, and a wet/dry vac. Every gallon you remove before the pros arrive reduces the damage.
Step 6: Dry Out the Structure
Extracting standing water is only the first half of the job. The second half — structural drying — is what prevents long-term damage. Wet drywall, wood studs, insulation, and subfloor materials must be dried completely or they will rot, warp, and grow mold.
Professional restoration companies use a combination of:
- Industrial air movers — high-powered fans that accelerate surface evaporation across floors, walls, and ceilings
- Commercial dehumidifiers — which pull moisture out of the air and force deeper evaporation from structural materials
- Moisture meters and thermal imaging — to find hidden pockets of moisture behind walls and under floors that are invisible to the eye
The drying process typically takes 3 to 5 days. Cutting this process short is one of the most common and costly mistakes homeowners make — materials that appear dry on the surface can still hold dangerous moisture levels inside.
Dallas's humidity makes dehumidification especially important. In summer, when outdoor humidity can exceed 70%, simply opening windows actually slows drying rather than speeding it up.
Step 7: Watch for Mold — Act Fast If You See It
Even after professional drying, mold can develop if any moisture was missed. Watch for:
- A musty or earthy smell, especially in closets or behind walls
- Visible dark spots (black, green, or gray) on walls, ceilings, or under carpets
- Bubbling or peeling paint and wallpaper
- Family members experiencing new respiratory symptoms or allergic reactions
If you see or smell mold, don't disturb it — airborne mold spores spread quickly and can colonize other areas of your home. Call a professional for mold remediation. In Dallas, where summer temperatures keep indoor spaces warm and damp even with air conditioning, mold spreads faster than in cooler climates.
Step 8: Assess the Structural Damage
After the water is removed and the structure is dry, a professional can assess whether any structural damage occurred. Common issues after flooding include:
- Warped or buckled hardwood floors — often need full replacement if water sat for more than a few hours
- Drywall damage — drywall that was submerged or saturated typically needs to be cut out and replaced
- Foundation issues — repeated flooding can cause soil movement under a slab foundation, leading to cracking
- Compromised load-bearing walls — wood studs that stay wet too long lose structural integrity
A professional flood damage repair assessment will identify what can be dried and saved versus what must be replaced.
Dallas-Specific Considerations
Flooding in Dallas has some particular characteristics that affect how you should respond:
- Flash flooding is the biggest risk. The DFW Metroplex receives most of its annual rainfall in violent spring and early fall storms. Water can rise faster than you can react — keep an eye on weather alerts and know your home's flood risk zone on the FEMA Flood Map Service Center.
- Clay soil doesn't drain. Dallas sits on heavy clay soil (the famous "black gumbo") that expands when wet and drains very slowly. This makes basement and crawl space flooding more common during extended rain events.
- Aging infrastructure in older neighborhoods. Areas like Lakewood, Downtown Dallas, and Uptown have older plumbing systems that are more susceptible to pipe failures during extreme weather.
- AC condensate line backups. In the summer, clogged AC condensate drain lines are a surprisingly common source of water damage in Dallas homes. If you notice water pooling near your indoor AC unit, address it immediately.
When to Call a Professional Water Damage Restoration Company

- Professionals have the equipment to extract and dry water 10x faster than consumer tools — and speed is everything when it comes to preventing mold.
- They have moisture meters and thermal cameras to find hidden water in wall cavities and subfloors that you can't see or feel.
- Licensed restoration companies can document damage for your insurance claim and often work directly with adjusters to streamline the process.
- They carry the proper protective equipment to safely handle contaminated water (sewage, floodwater) without exposing your family to pathogens.
