A Lewisville water damage call, start to finish

Lewisville grew up beside a federal dam. Lewisville Lake, which holds back the Elm Fork of the Trinity, is owned by the U.S. government and operated by the Army Corps of Engineers for water supply, flood control and recreation, and the city of about 140,000 spreads out below and around it in Denton County.

Still, the water damage most Lewisville homes see does not come from the lake. It comes from a water heater giving out in a garage, a sink supply line, a running toilet, a slab leak, or a summer storm that overloads a street drain. If you are searching "water damage Lewisville TX" with wet floors in front of you, the steps are the same: stop the water, stay safe, take pictures, then call.

Water Damage Pro Dallas is a free phone line, not a restoration company. Dial (469) 649-7066 and an automated assistant takes down what is wrong, then sends the call on to an independent, locally owned restoration company that serves Lewisville. That company inspects, writes its own estimate and does the work if you hire it.

The dam, the 2015 spill and what changed

The Texas Water Development Board lists the lake's normal conservation pool at 522 feet above sea level and the top of its flood pool, which is also the spillway crest, at 532 feet. Water above that line goes over the spillway.

That happened in the wet spring of 2015. NBC DFW later reported that the lake reached about 537 feet and that the spill caused street flooding in areas below the dam but did not get into structures. In June 2015 a landslide hit the upstream face of the dam's embankment, and an August 2015 review found other safety issues, including seepage. Those problems helped win $150 million for Corps upgrades at the dam, and a July 2026 Corps update said the spillway work, which added more than 70 anchors driven into the bedrock, was nearing completion.

For a homeowner, the practical point is narrower: a standard home policy does not cover flood from any source, lake or creek. If your address is in or near a mapped flood zone, ask about a separate flood policy now, because FEMA says a new National Flood Insurance Program policy generally waits 30 days before it takes effect.

February 1, 2025: when Timber Creek took out a main

The most recent big water event in Lewisville started underground, not in the sky.

Saturday, about 10 p.m. A 30-inch water main failed and pressure dropped across central Lewisville. The city said about 80 percent of its water customers were affected.
The cause. City officials said erosion along Timber Creek separated the pipe and let water out very quickly.
Service back, notice stays. Pressure came back within about three hours, but state rules required a boil water notice, and Lewisville ISD closed 21 schools and facilities on Monday.
Monday afternoon. Tests showed the water was safe and the notice was lifted at 2 p.m. The city told residents to flush their pipes and water heaters and run an empty dishwasher cycle.

A pressure drop like that does not usually flood homes, but sudden pressure changes can show up later as a drip at an old valve or fitting. If you find a new leak after a citywide outage, treat it like any other leak: shut it off and call.

Water damage restoration in Lewisville's 1970s and 1980s neighborhoods

The city's own history says Lewisville had roughly 9,200 residents in 1970 and close to 25,000 a decade later, with whole neighborhoods going up almost overnight, and that home building kept going through the 1980s. Many of those houses are now 40 to 55 years old. Old Town, the original downtown, dates to the 1880s, when the railroad arrived about two miles east of the first settlement and the town moved to meet it.

Houses of that age have usually had some plumbing replaced, but not always all of it. When water damage shows up in an older Lewisville home, ask the company to look for the source before drying anything:

Water heaters in garages or closets, and the pan and drain line under them
Original shutoff valves that may not close fully when you need them
Supply lines to toilets, sinks, ice makers and washers
Lines under the slab, where a leak shows up as a warm or damp floor or a bill that climbs with no change in use
AC condensate lines in the attic that drip into a ceiling

A plumber stops and fixes the leak. The restoration company traces where the moisture went, removes what cannot be saved and dries the rest. The slab leak page explains how those two jobs fit together.

Lewisville numbers and utilities

City water

Public Works: 972-219-3510. Water billing: 972-219-3440. Police and fire non-emergency: 972-219-3600. Anything dangerous: 911.

Electric

Lewisville is split between two power delivery companies, Oncor and Texas-New Mexico Power, depending on the address. Your electric bill names yours. Report outages and downed lines to that company.

Permits

Building Inspections: 972-219-3470. The city's permit page lists plumbing and electrical repairs and water heater replacements among the permit types, and a city handout says a water heater installation needs a permit.

Safety first. Shut off the main water valve if you can get to it without risk. Water and electricity together are the real hazard, so stay out of any puddle that touches an outlet, a cord or an appliance. Switch off the breaker only when the panel can be reached from dry flooring; if it cannot, call your electric delivery company (Oncor or TNMP, as your bill shows) or an electrician. A gas smell means everyone goes outside, and the calls to 911 and Atmos Energy or the gas company on your bill are made from there. Floodwater and sewage are not safe to wade through, for adults, children or pets. Once everyone is safe, take photos for the insurance claim and carry valuables and documents to a dry room.

The 2021 freeze in Lewisville

During the February 2021 winter storm, Lewisville came through with less disruption to its water system than many neighbors. Community Impact reported that the city put one service area near the northeastern Sam Rayburn Tollway corridor, about 3,500 residents, under a boil notice after pressure fell below 20 pounds per square inch, while most of the city was not under a notice as of February 18. Frozen pipes inside homes were another matter. The city waived plumbing and electrical permit fees for storm repairs, though permits and inspections were still required.

For the next hard freeze, know where your main shutoff is and whether it turns, and look at which pipes run through the attic or an outside wall. The burst pipe page covers the cleanup.

Five things to ask a restoration company in Lewisville

What is the source, and is it fixed? Drying a house while the leak still runs wastes your money.
What category of water is it? Under the ANSI/IICRC S500 standard, clean supply-line water, gray appliance water and black sewage or floodwater call for different handling.
Can I have the estimate in writing? Including what will be torn out and why.
Who pulls the permits? Plumbing, electrical and water heater work in Lewisville needs them.
Can you show your firm on the IICRC Global Locator and send a certificate of insurance? Then check both yourself.

Ask your insurer, not the contractor. Guidance from the Texas Department of Insurance separates water that shows up suddenly and by accident, like a split pipe, an overflowing toilet or a failed washer hose, which most home and renter policies include, from slow leaks and seepage, which they usually leave out. Flooding is excluded from home policies altogether and needs a separate flood policy. Insurers can also refuse a claim when the owner did not take reasonable steps to limit further damage. Before you sign for any work, pull out your policy and call the insurer about what it includes. More on water damage and insurance.

Lewisville water damage questions

Does Lewisville Lake flood the houses in town?

The lake is a flood control reservoir run by the U.S. Army Corps of Engineers, and its spillway crest sits at 532 feet. In 2015 the lake rose to about 537 feet and spilled; reporting afterward said streets below the dam flooded but water did not get into buildings. Most Lewisville water damage starts inside the house or with local runoff, not the lake. Look up the house on FEMA's flood map, and see flood damage restoration if outside water gets in.

Who do I call in Lewisville about a water main or meter problem?

The city's contact list gives Public Works at 972-219-3510 and water billing at 972-219-3440, with police and fire non-emergency at 972-219-3600. Call 911 if anyone is in danger. A leak past the meter, inside your walls or under your slab, is a private repair: close your own shutoff, call a plumber, and then call about drying the house.

My Lewisville water heater burst in the garage. Does the new one need a city permit?

Yes. A City of Lewisville handout says installing a water heater requires a permit. State law lets a homeowner do that work on their own homestead, but anyone else doing it must be a licensed plumber registered with the city. Building Inspections answers questions at 972-219-3470. The restoration company dries the garage and walls; the plumber handles the heater. See water damage repair.

How long can water sit before mold starts in a Lewisville house?

The EPA says that mold usually does not take hold when damp materials get dry inside 24 to 48 hours. That is a guideline, not a promise, and wet insulation or carpet pad can stay damp longer than it looks. If mold has already spread across a large area, Texas rules generally call for licensed professionals; the Texas mold rules guide explains when.
