Hard freezes are rare in Carrollton, which is exactly why they do so much damage. Supply lines here often run through attics and exterior walls with little insulation, and the February 2021 winter storm split pipes across Dallas County. The leak usually appears when the ice thaws and pressure returns, sometimes days after the cold snap.
Where freeze damage starts in North Texas homes
- Supply lines running through the attic above bedrooms and hallways
- Pipes in exterior walls on the north and west sides of the house
- Lines to garage water heaters, laundry rooms and outdoor hose bibs
- Uninsulated lines in garages and above unheated porches
Why an attic break is worse
A split line in the attic dumps water onto insulation and ceiling drywall. Wet blown insulation compresses and holds water against the drywall, the ceiling sags, and water runs down wall cavities to the slab. The mitigation team removes saturated insulation, drops ceiling drywall that cannot be saved and dries the framing.
How the cleanup runs
- Water is shut off and the line made safe for the plumber.
- The extraction crew clears standing water and saturated carpet pad.
- Moisture mapping follows the water from the attic down through each wall.
- Air movers and LGR dehumidifiers dry ceilings, cavities and the slab edge until readings meet the drying goal.
Hard freeze in the forecast? Let faucets drip on outside walls, open cabinet doors under sinks and know where the main shutoff is before the temperature drops.
