Frozen pipe repair in San Antonio, TX
Ice in a line is a two part problem: the blockage now and the split that floods when it thaws. We warm the run slowly, fix what cracked and insulate what was exposed.
Signs you need this
- No water from a tap during a freeze
- Frost on exposed pipe
- Bulging or split pipe
- Water spraying after a thaw
Why it happens
Water expands when it freezes, and that pressure splits pipe, usually somewhere other than where the ice is. San Antonio does not freeze often, so many homes have pipes in attics, exterior walls and outdoor spigots with little or no insulation. The February 2021 storm showed how fast that turns into flooding.
The worst damage usually shows up after the thaw, not during the freeze. Ice holds the split closed, then as it melts water sprays from a crack inside a wall or attic. If you suspect a frozen pipe, it helps to know where your main shut-off is before you start warming anything. We thaw lines gradually so fittings are not stressed, check each run for splits before turning water back on, and repair what failed. Then we look at why it froze: missing insulation, a pipe in an outside wall, an unheated garage or an old hose bib, and fix that so the next freeze is a non-event.
What we check first

What affects the price
Thawing and inspecting is a service visit. Each split adds parts and time. Freeze-proofing work like insulation and frost-free spigots is quoted separately and is worth doing before winter.
Before a hard freeze, disconnect hoses, cover outdoor spigots, open cabinet doors on exterior walls and know where your main shut-off is.
Frozen pipe repair questions
Should I use a torch to thaw pipes?
No. Open flame is a fire risk. Use gentle heat or call us.
Should I drip my faucets?
During a hard freeze, a slow drip on exterior wall faucets helps.
Do you work during freezes?
Yes, 24 hours a day. Freeze nights are some of our busiest.
How do I find my main shut-off?
Usually near the meter in the front yard or where the line enters the house. We can show you on any visit.
