Water in your Lewisville home? Close the main valve, then call.

What comes first when water is moving through a Lewisville house?

Close the main water valve, then keep people and pets out of standing water near outlets, cords and appliances. Turn off power to the wet area only if the panel is dry and easy to reach. After that, photograph the damage, lift valuables off wet floors and call so a crew can start extraction and drying.

If the water is coming through a ceiling, stay off the drywall below it. A saturated ceiling can drop without warning, and the insulation above it may be holding more water than the stain suggests. For a heater in the attic, close its cold-water valve and its power or gas only if you can reach them without climbing into wet insulation.

The crew can help you find the right valve and make a leak safe to leave, and a burst pipe cleanup starts with exactly that. The pipe itself is a licensed plumber's job.

• Stop the source: the main for a split line, the heater's cold-water valve, or the small valve behind a toilet, washer or ice maker.
• Stay clear of power: skip any room where water reaches outlets, power strips or the air handler closet.
• Photograph it: short videos and photos of every wet room before furniture, rugs or boxes move.
• Lift what you safely can: boxes and electronics off wet floors, foil or blocks under furniture legs.
• Hold off on demolition: wet drywall and pad are judged with meters, so leave them in place for now.

Why does Lewisville Lake matter to a water damage call?

Lewisville Lake is a Corps of Engineers reservoir on the Elm Fork of the Trinity River in Denton County, and its level, its creeks and the storm drains around it decide where outside water can go. On May 31, 2015 the lake set a pool of record of 537.02 feet, against a normal pool of 522.

That 2015 high water topped the spillway at 532 feet. Reports described street flooding in areas below the dam and said water did not enter structures, and the episode helped win roughly $150 million of dam upgrades, about half of it for the spillway. No source puts lake water inside homes in any named town, so this page does not claim it.

Put plainly, at the normal pool of 522 feet the lake sits about ten feet below the top of the spillway. Water that arrives from a lake, a creek or a flooded street is treated as contaminated from the start, and it is usually a flood loss that needs a separate flood policy. The Lewisville Lake and Elm Fork guide lays out the dates and levels.

When does water trouble hit Lewisville homes?

North Texas water problems follow the weather: hard freezes from December to February, hail and flash flooding from March through June, air conditioner condensate overflow and under-slab leaks in July and August, then a second wet spell in the fall. Treat the table as a rough guide, since any year can run early or late.

Check National Weather Service Fort Worth for freeze, hail and flash flood warnings, and read the table for what is worth doing before each stretch.

What did the February 2021 freeze do to Lewisville plumbing?

Lewisville Fire Department and city crews answered 973 calls for broken water pipes between Sunday, February 14 and Sunday, February 21, 2021. The city waived plumbing and electrical permit fees for storm repairs, though permits and inspections were still required. Lines in attics and exterior walls are the usual casualties, and they often leak only once they thaw.

Nearly a thousand calls in eight days tells you how many household lines let go at once when a hard freeze thawed, not just in a few houses. The city kept inspections in place even as it waived the fees. If you are repairing plumbing today, ask the city's building department what a permit needs.

Four years later, in February 2025, a separate and unrelated event hit the city. A 30-inch main failed on the night of February 1 and a boil-water notice covered nearly 80 percent of city customers for about 36 hours. That was a drinking-water advisory about city infrastructure, not a flood, and it had nothing to do with the 2021 freeze or with water damage inside any home. The 2021 freeze guide covers the pipe side.

What does water damage cleanup cost in Lewisville?

Cost guides report a typical Dallas-Fort Worth whole-job range of roughly $1,200 to $5,000, and a minor one-room extraction and drying job often lands between $500 and $1,500. These are 2026 working estimates for Denton County. The emergency-stage price is confirmed on site and approved by you before work starts.

The total moves with how many square feet got wet, whether the water is clean, gray or sewage, what the floors and walls are made of and how many drying days the readings call for. Every line is on the price page, with the reasons behind each range.
