Signs Your Pipes Are About to Freeze (and What to Do Fast)

Cold weather might not last long along the Mississippi and Louisiana Gulf Coast, but when it hits, it can cause serious plumbing problems fast. Frozen pipes are one of the most damaging — and expensive — issues a homeowner can face.

The good news? There are clear warning signs your pipes are about to freeze, and quick steps you can take to prevent a costly disaster.

1. Slow or No Water Flow

If you turn on a faucet and only a trickle comes out — or no water at all — your pipes may be freezing. Ice inside the pipe restricts water flow and pressure.
👉 Act fast: Turn off your main water valve to relieve pressure and open nearby faucets to allow any remaining water to flow through once thawed.

2. Frost on Exposed Pipes

See frost or ice on visible pipes in crawl spaces, attics, or under your home? That’s a red flag. It means the temperature of that section has dropped below freezing.
👉 Act fast: Gently warm the area using a space heater or hair dryer — never an open flame. Keep the heat moving evenly to avoid damaging the pipe.

3. Strange Smells Coming from Drains

When pipes start to freeze, ice can block airflow, pushing sewer gases back up through your drains. If you notice a strange odor, especially in rarely used sinks or tubs, it’s time to investigate.
👉 Act fast: Run warm water down drains, open cabinet doors under sinks, and increase heat in that part of the home.

4. Unusual Sounds in the Plumbing

Banging, gurgling, or clanking noises could signal trapped air and water trying to push past ice in your lines.
👉 Act fast: Turn off the main water supply and safely warm the affected area. If the noise continues, contact a plumber immediately to prevent a rupture.

5. Water Damage or Wet Spots on Walls and Floors

If a frozen pipe bursts, water will start to leak once it thaws — often behind walls or under floors.
👉 Act fast: Shut off your water supply, turn off your water heater, and call a licensed plumber right away to locate and repair the damage before it spreads.

What to Do Right Now to Prevent Freezing:

• Let faucets drip slightly overnight when temperatures drop below 30°F.

• Open cabinet doors under sinks to let warm air circulate.

• Insulate exposed pipes in crawl spaces, attics, and exterior walls.

• Keep your thermostat set to at least 55°F — even if you’re away.
