A frozen pipe often hides the damage until the thaw, when ice that has split the pipe melts and water pours into the wall or ceiling. A house left empty during a cold snap can run for a long stretch before anyone sees a stain.
Where freezing pipes split
Pipes in exterior walls, unheated spaces and attics are the usual victims, along with supply pipes feeding outdoor faucets. A split only a few inches long can release a large amount of water once the ice thaws.
What to do while it thaws
- Shut off the main valve before the pipe thaws if a split is suspected
- Open faucets after the shutoff so the system can drain
- Keep heat on and open cabinet doors to warm exposed pipes
- Photograph frost, splits and wet surfaces before repairs begin
Drying after the thaw
Extraction comes first, then wet drywall and insulation in the affected walls and ceilings are removed, and LGR dehumidifiers and air movers dry the cavities. A plumber repairs the split, and the frozen pipe risk check tool helps judge how exposed a house is before the next cold snap.
