If floodwater gets inside your home or business, get everyone out of the water, shut off power to wet areas if you can do it safely, and call for professional water removal as soon as possible. Photograph everything before you move it. Wet drywall, flooring and insulation need to be dried or removed within 24 to 48 hours.
Flash flooding in Kaufman and Rockwall counties rarely gives much notice. A line of storms parks over the area, the ditches along FM 548 and FM 740 fill up, and water that normally drains off a lot in minutes starts pooling against a slab. Neighborhoods in Forney, Heath, Fate and Royse City were built quickly on flat Blackland Prairie clay, and that soil does not soak water up fast. When the rain outruns the drainage, water looks for the lowest way in, and that is often your garage door or back patio slider.
This guide walks through what to do in the first hours, what not to do, and how to tell the difference between water you can handle and water that needs a crew.
What counts as a flash flood in North Texas?
The National Weather Service describes a flash flood as rapid flooding that starts within about six hours of heavy rain, and often much sooner. Around here that usually means a thunderstorm that drops a lot of rain in a short time, or several storms that train over the same neighborhoods one after another.
Fall is a real part of that picture. Spring gets most of the attention, but cold fronts that push through North Texas in October and November can set off slow-moving storms with heavy rain. When the ground is already wet from earlier storms, it takes less rain to cause problems.
Why does water get inside so many Forney and Rockwall homes?
Most homes in this area sit on concrete slab foundations, so there is no crawlspace or basement to catch water. Once water comes over the threshold, it spreads across the slab under carpet, vinyl plank and laminate. It also wicks up the bottom of drywall and into the wood plate that sits at the base of every wall.
A few local patterns show up again and again:
- Lots that drain toward the house. Newer subdivisions are graded to move water to the street, but a settled flower bed, a new patio or a blocked side yard swale can send runoff toward the foundation instead.
- Garages that sit lower than the house. Water often enters the garage first, then slips under the door into a laundry room or mudroom.
- Homes near creeks and low areas. Properties along creeks that feed the East Fork of the Trinity River and the low ground around Lake Ray Hubbard can see water rise faster than the street drains can handle.
- Clay soil that holds water. Our heavy clay drains slowly, so water can stand against the foundation for hours after the rain stops.
Is it safe to go back into a flooded building?
Only when the water has stopped rising and you are sure the power is off in the wet area. Floodwater and electricity are a dangerous mix, and you cannot see a submerged outlet or extension cord.
Before you step in, ask yourself these questions:
- Is the water still coming in, or has it peaked?
- Can you reach your breaker panel without walking through water?
- Is there any smell of gas? If so, leave and call the gas utility from outside.
- Are there signs the structure moved, such as sagging ceilings or doors that suddenly will not close?
If any answer worries you, stay out and wait for help. Your belongings can wait. You cannot.
What should I do in the first few hours after the water stops?
Once it is safe, the goal is to limit how far the water travels and to keep a clear record of what happened. Here is the order that works best on most jobs:
- Turn off power to wet rooms. Use the breaker panel only if you can reach it from a dry spot.
- Document everything. Take wide photos of each room, then close ups of the waterline on walls, damaged flooring and furniture. Video works well too.
- Move what you can. Lift furniture onto blocks or move it to a dry room. Pull rugs, boxes, photos and papers out of the water.
- Remove standing water if it is shallow and clean enough to handle. A wet vacuum helps on small areas. Leave deep or dirty water to a crew with pumps and protective gear.
- Do not turn on the HVAC if ducts or the air handler took on water. You can spread moisture and debris through the house.
- Call your insurance company and a restoration company. Document everything for your insurance company and check your policy for reporting steps and deadlines.
Is floodwater different from a burst pipe?
Yes, and it matters for how the cleanup is handled. Water from a broken supply line starts out clean. Water that runs across yards, streets and driveways picks up soil, fertilizer, oil and whatever else is on the ground. Restoration crews treat that water as contaminated.
That changes a few things:
- Porous materials that soaked in floodwater, such as carpet pad, the bottom of drywall and insulation, are usually removed rather than dried in place.
- Hard surfaces are cleaned and disinfected before drying equipment goes in.
- Crews wear protective gear and keep contaminated debris out of clean parts of the house.
Coverage can also be different. FEMA notes that standard homeowners policies generally do not cover flood damage, which is usually handled through separate flood insurance. Every policy is different, so check yours and ask your agent how rising water is treated.
How fast does a flooded building need to be dried?
Fast. The EPA advises drying wet building materials within 24 to 48 hours to prevent mold growth. On a slab home that took on water, that means pulling up wet flooring where needed, cutting drywall above the waterline, and setting commercial dehumidifiers and air movers.
Household fans help a little, but they cannot reach water trapped under flooring or inside a wall cavity. Restoration technicians use moisture meters to find where the water went and check readings every day until materials are back to normal.
What does professional flood cleanup look like?
Every job is different, but most flood cleanups follow the same basic path:
- Inspection and moisture mapping to see how far water traveled under floors and up walls.
- Water extraction with truck mounted or portable pumps and extractors.
- Removal of materials that cannot be saved, such as soaked carpet pad and drywall below the flood cut.
- Cleaning and sanitizing the slab, framing and other surfaces that stay.
- Structural drying with dehumidifiers and air movers until readings confirm the building is dry.
- Rebuild, including drywall, flooring, trim and paint.
At Best Option Restoration of Forney Rockwall, that last step stays with the same team. We handle Emergency Water Damage Restoration and Storm Damage Restoration from the first extraction through the finished walls, so you are not hunting for a second contractor while you are still drying out.
First steps after floodwater gets inside
If you only remember one part of this post, make it this list.
- Get to safety first. Never walk or drive through moving water. The National Weather Service warns that six inches of moving water can knock an adult down, and about a foot can carry away a small car. Turn around, don’t drown.
- Cut power to wet areas from a dry spot. If you cannot reach the panel safely, leave it for the utility or an electrician.
- Take photos and video before you clean. Capture the waterline, the flooring and anything damaged.
- Pull belongings out of the water. Start with items that cannot be replaced, like photos and documents.
- Call for water removal the same day. The 24 to 48 hour drying window starts when the water arrives, not when the storm ends.
- Keep receipts. Hotel stays, supplies and repairs you pay for out of pocket should all be saved for your claim.
