Lewisville flood, storm, water and fire damage restoration

Lewisville lies mostly in Denton County, with a sliver in Dallas County, on the eastern Cross Timbers between the Blackland Prairie and the Grand Prairie. The Garza-Little Elm Dam, finished in 1954, created today's Lewisville Lake, and the Elm Fork flows south through town with Timber Creek and Prairie Creek as tributaries. The city grew from about 78,000 residents in 2000 to more than 111,000 in 2020, and annexing Castle Hills in 2021 added roughly 18,000 more.

Lake, creeks and Tornado Alley weather

Where the Elm Fork meets the lake, a delta stretches nearly seven miles south, and FEMA maps much of that area as Zone AE, a 100-year flood zone. Timber Creek can overflow during heavy rain and has occasionally flooded nearby homes. The city averages about 38 inches of precipitation a year, and temperatures have ranged from 113 degrees down to 3 below zero.

The lake itself can turn rough: when Hurricane Carla affected the area in 1961, winds reached 86 mph and swells hit six feet. Denton County's federal declarations since 2000 include severe storms and tornadoes in 2007 (two declarations), storms and flooding in 2015 and 2024, the 2021 Severe Winter Storms, the 2006 Extreme Wildfire Threat and Hurricane Rita in 2005.

Leaks, freezes and water damage restoration in Lewisville

Most indoor losses start with plumbing and appliances: water heaters, dishwasher and refrigerator lines, and washing machine hoses. Hard freezes such as the February 2021 storm can split pipes in attics, garages and outside walls. Roofs hammered by spring hail may leak only during the next heavy rain.

Effective water damage restoration usually includes stopping the source, extracting water, checking walls and floors with moisture meters and running dehumidifiers until materials are dry. The water extraction and structural drying guides cover what crews do in each phase.

Federal disaster declarations that included Denton County

FEMA records show Denton County was included in 7 major disaster declarations for weather or fire events from 2000 through 2026 (3 severe storm, 1 flood, 1 severe ice storm, 1 fire, 1 hurricane, by FEMA incident type). Declarations are made at the county level, so they do not mean every neighborhood in Lewisville was affected. The most recent:

Handling smoke and fire damage

House fires most often start in kitchens, dryers and electrical systems. In apartment complexes and townhomes, smoke can spread to adjoining units, and water from firefighting adds a second layer of damage. Denton County was also part of the 2006 wildfire-threat declaration.

Restoration firms typically secure openings, remove charred material, clean soot by residue type, clean ducts and deodorize. Our fire damage cleanup page and smoke odor removal page explain the methods.

When Timber Creek rises or a storm rolls through

Heavy rain can push creek water into homes near Timber Creek and other low spots, and properties in the mapped delta flood zone face the highest risk. Water that enters from outside is Category 3 and may carry sewage, fertilizer and debris.

Contractors commonly extract water, cut out wet drywall above the waterline, remove soaked carpet and pad, disinfect and dry. After hail or high winds, roof tarping and board-up come first. Visit flood cleanup and storm damage cleanup for details.

Mold after leaks and creek flooding

North Texas summers are hot and humid, so anything left wet for a day or two can begin to grow mold. Look behind baseboards, under sinks and in closets after any leak or flood.

EPA guidance indicates homeowners can usually clean patches under about 10 square feet once the moisture problem is fixed. For larger areas, hidden growth or mold after floodwater, consider a company that handles mold remediation with proper containment.

First moves for Lewisville homeowners and renters

• Call 911 for fire, injuries, gas odors or anyone caught in rising water.
• Stay away from creek banks and flooded roads during storms.
• Shut off the main water valve when a pipe or appliance line breaks.
• Keep clear of rooms with sagging ceilings or standing water near outlets.
• Photograph damage and belongings before cleanup; keep receipts.
• Ask your agent whether you have flood coverage; standard homeowners policies often exclude it, and coverage depends on your policy.
