Frozen Pipes in Houston

Frozen Pipes — illustrated guide

No water or a trickle from a faucet during freezing weather. Here's what to do about frozen pipes in Houston — including the local factors that change the advice.

Do this right now

1

Open the faucet

Open the affected faucet slightly. Flowing water — even a trickle — helps melt ice and gives it somewhere to go.

2

Warm the pipe gently

Hair dryer, heating pad, or warm (not hot) towels on the frozen section, working from the faucet back toward the blockage. Never an open flame or heat gun on high.

3

Check for leaks as it thaws

Watch closely — the real danger is a split you can't see until water flows. Have the main shutoff location ready.

4

Know when to stop

If you can't find the frozen section, if it's inside a wall, or if thawing reveals any leak — stop and call.

5

Call before it bursts

Call (844) 699-1165. A pro can thaw safely, check for splits, and insulate the vulnerable runs so it doesn't happen again.

What makes frozen pipes different in Houston

  • In Houston, rare but real — the 2021 freeze caught Houston unprepared, with burst pipes across the metro
  • slab-on-grade homes across flat bayou country, many built from the 1960s–90s — pipes in these spots freeze first.
  • hurricanes, tropical storms, and intense Gulf humidity
  • Flat terrain and high water table mean flooding, not basements — storm drainage overwhelms systems fast

Neighborhoods

If you're in The Heights, Montrose, River Oaks, Galleria, Katy, Sugar Land, The Woodlands, Pasadena, Midtown, Energy Corridor, or anywhere across the Houston metro — Houston, Pasadena, Baytown, Sugar Land, The Woodlands — the steps above apply. Call (844) 699-1165 and mention your neighborhood so we match you with a pro who knows the area.

What to tell the pro when you call

  • Which fixtures are affected and the outdoor temperature
  • Where you suspect the freeze is: attic, crawlspace, exterior wall, garage
  • Whether any water is flowing at all
  • The age and material of your pipes if known
  • Whether this has happened before (recurring freezes need insulation fixes)

At what temperature do pipes freeze?
Uninsulated pipes in unconditioned spaces can freeze around 20°F (-7°C), and wind chill on exterior walls makes it worse. Pipes have burst at higher temps when exposed.
Should I drip faucets during a freeze?
Yes — a slight drip on faucets served by vulnerable pipes relieves pressure, which is what actually prevents bursts. Also open cabinet doors under sinks on exterior walls.
