Where flooding actually happens in Lewisville
Most Lewisville homes will never see the lake come to them. The dam was built in the 1950s to hold back floods, and it does that job. Home flooding here tends to come from rain that falls faster than streets and creeks can carry it away.
The Elm Fork of the Trinity River runs south from the dam through Lewisville. Timber Creek and Prairie Creek cross town on their way to it. When a slow storm sits over Denton County, those channels rise quickly and low streets near them can back up into garages and slab-level living rooms.
Wet years add pressure. May 2015 brought close to 17 inches of rain, and the lake poured over the spillway that June. In October 2018, DFW’s wettest October on record pushed the lake within a few feet of the spillway again. During stretches like that, the ground stays soaked and even small storms cause runoff.
Safety first
After floodwater comes in: a checklist
Floodwater carries sewage, fuel, and yard chemicals. Wear boots and gloves, keep kids and pets out, and never enter a room where water may touch outlets.
- Shut off power at the main breaker if water reached outlets and you can get there dry.
- Photograph everything before you move it, including the water line on walls.
- Call your flood carrier if you have an NFIP or private flood policy.
- Do not use a household vacuum on floodwater. It is a shock risk and spreads bacteria.
- Throw out food and any medicine the water touched.

The work
What flood water restoration includes
Floodwater is Category 3 under IICRC S500. That changes what can be saved.
Pump and extract
Submersible pumps for deep water, then truck-mount extraction for carpet and hard floors.
Remove porous materials
Carpet, pad, and drywall touched by floodwater usually cannot be cleaned safely. We make flood cuts about 2 feet above the water line.
Clean and disinfect
Studs, slab, and cabinets that stay get cleaned and treated with an antimicrobial before drying.
Structural drying
Dehumidifiers and air movers run until wall cavities and framing hit dry readings, usually 3 to 5 days.
Contents
We sort belongings, pack out what can be cleaned, and list the rest for your claim.
Rebuild
New drywall, insulation, trim, and flooring once the structure is dry and clean.
Flood insurance and cost in Lewisville
This is the part that surprises people. A standard homeowners policy does not cover rising water from outside. Flood coverage comes from the National Flood Insurance Program or a private flood policy, and NFIP policies usually have a 30-day wait before they start.
Water that comes in from above is different. If wind-driven rain gets through a damaged roof or window, your homeowners policy may cover it. That is why the cause matters so much, and why we photograph the entry point.
Cost depends on how deep the water got, how long it stood, how many rooms were hit, and how much has to be removed. Flood jobs cost more per room than clean-water leaks because of tear-out and disinfection. You can check your flood zone on the FEMA Flood Map Service Center and get a rough number from our water damage cost calculator.
Why call a local flood restoration company
After a big storm, crews from far away get booked for days. We are based in Denton, one straight shot down I-35E, and we aim to have a crew at most Lewisville homes in about 60 minutes. Every flood job gets moisture mapping, daily logs, and photos for your adjuster.
We also keep an eye on what comes after. Floodwater leaves silt and bacteria in wall bottoms and on slabs, and missed spots turn into odor and mold within days in warm weather. Our final walk-through confirms every cut wall and floor area is clean and dry before we close anything up.

FAQ
Lewisville flood cleanup questions
Is my Lewisville home in a flood zone?
Look up your address on the FEMA Flood Map Service Center. Homes near the Elm Fork, Timber Creek, or Prairie Creek are more likely to sit in or near a mapped floodplain, but flooding can happen outside mapped zones too.
Can floodwater-soaked carpet be saved?
Usually not. Carpet and pad that sat in outside floodwater are considered contaminated and are removed. Some hard surfaces and furniture can be cleaned and disinfected.
Why cut drywall 2 feet up if the water was only 6 inches deep?
Drywall wicks water upward, and the insulation behind it holds moisture. A flood cut above the wet line lets us dry and disinfect the wall cavity instead of sealing contamination inside.
Does the lake flood Lewisville neighborhoods?
Rarely. The Corps manages the lake level with the dam. Most home flooding in Lewisville comes from heavy rain and creek overflow instead.
What if water came in through the roof during the storm?
That is not usually treated as flood. Rain entering through storm damage is often a homeowners claim. See our Lewisville storm damage page for that situation.
How long does flood cleanup take in a Lewisville home?
Extraction and tear-out usually happen on day one. Drying takes about 3 to 5 days after that. Rebuilding drywall, trim, and flooring can take one to several weeks depending on how many rooms were hit.
