Should You Call a Plumber for Frozen Pipes?

Waking up to no water—or worse, a burst pipe—in the middle of winter is every homeowner’s nightmare. If you’re asking yourself, “Should you call a plumber for frozen pipes?”, you’re not alone. This common but urgent issue affects thousands of U.S. households every winter, often when temperatures drop below 20°F. The good news? Quick, informed action can prevent thousands in water damage. Let’s break down exactly when you can handle it yourself—and when it’s time to call a licensed plumber immediately.

What Causes Pipes to Freeze?

Pipes freeze when surrounding temperatures fall below freezing (32°F or 0°C) for an extended period—especially in uninsulated spaces like attics, basements, crawl spaces, or exterior walls. According to the U.S. Department of Energy, even pipes in heated areas can freeze if cold air infiltrates through cracks or poor insulation.

Key risk factors include:

• Outdoor temps below 20°F for 6+ hours
• Poor insulation or drafty areas near plumbing
• Pipes exposed to wind (e.g., under kitchen sinks on exterior walls)
• Homes in colder regions like the Midwest or Northeast

Frozen pipes don’t just stop water flow—they can burst under pressure, causing catastrophic flooding. The Insurance Institute for Business & Home Safety reports that burst pipes are one of the most common and costly winter home insurance claims, averaging over $15,000 per incident.

Can You Thaw Frozen Pipes Yourself?

Sometimes—yes. But only if:
✅ The pipe is visible and accessible (not inside a wall)
✅ You see no signs of cracking or leaking
✅ You’re comfortable using safe thawing methods

Safe DIY Thawing Steps (Step-by-Step)

1. Turn on the faucet – This relieves pressure and allows steam/melted water to escape as ice thaws.
2. Locate the frozen section – Usually the coldest spot or where frost appears on the pipe.
3. Apply gentle heat using one of these tools:
   • Hair dryer (keep 6+ inches away)
   • Space heater (never leave unattended)
   • Hot towels (soak in warm—not boiling—water, ~100–110°F)
   • Electric heating pad (wrap around pipe, low setting)

Never use:
❌ Open flames (propane torches, lighters)
❌ Boiling water (can crack cold metal)
❌ Anything that causes rapid temperature swings

⚠️ Caution: If you see moisture, bulging, or hairline cracks—stop immediately. A thawing frozen pipe that’s already compromised can burst within minutes.

When Should You Call a Plumber for Frozen Pipes?

Call a licensed plumber right away if:

• The frozen pipe is inside a wall, ceiling, or under flooring
• You suspect a leak or hear dripping after thawing begins
• Water isn’t flowing even after 30–45 minutes of safe thawing
• You’re uncomfortable using heat tools near plumbing or electrical systems
• Your home loses all water pressure suddenly in cold weather

Professional plumbers use infrared cameras to locate hidden ice blockages and controlled thawing systems that minimize burst risk. They can also inspect for micro-fractures that may fail days later—a hidden danger DIY methods can’t detect.

According to HomeAdvisor, 68% of frozen pipe emergencies that result in flooding involve pipes behind walls, where damage goes unnoticed until ceilings stain or floors warp.

💡 Pro Tip: Many plumbing companies offer emergency same-day service in winter. Save their number before a freeze hits.

How to Prevent Frozen Pipes Next Winter

Don’t wait for another scare. Take these proactive steps when temps drop:

1. Insulate vulnerable pipes with foam sleeves ($0.50/ft at hardware stores).
2. Seal cracks near plumbing with caulk or spray foam.
3. Keep cabinet doors open under sinks on exterior walls to allow warm air circulation.
4. Let faucets drip (5–10 drops/minute) when temps fall below 20°F—this relieves pressure.
5. Set thermostat no lower than 55°F if you’re away.

The CDC recommends these steps as part of winter home preparedness, especially in historically cold states like Minnesota, Colorado, or Maine.

FAQ: Should You Call a Plumber for Frozen Pipes?

Q: How long does it take for pipes to freeze?

A: Pipes can freeze in as little as 6 hours when temps are below 20°F—especially if uninsulated or exposed to wind.

Q: Can a frozen pipe thaw on its own?

A: Yes, but not safely. As ice melts, pressure builds behind the blockage. If the pipe is weakened, it may burst during thawing—even if it survived the freeze.

Q: What temperature should I keep my house to prevent frozen pipes?

A: Maintain at least 55°F indoors, even when away. In extreme cold, 60–65°F is safer for older homes or poorly insulated pipes.

Q: Will insurance cover burst pipes from freezing?

A: Most homeowners insurance policies cover sudden, accidental water damage from burst pipes—but not if you failed to maintain heat or insulate (considered negligence). Always document your prevention efforts.

Q: Can I use a space heater to thaw pipes?

A: Only if you stay in the room and keep the heater 3+ feet from flammables. Never leave it running overnight or unattended—this is a leading cause of winter house fires.

Q: How do I know if a pipe has already burst?

A: Signs include:

• Wet drywall or flooring
• Musty odors
• Unexplained spikes in water bills
• Low water pressure in specific zones
  If you see any of these, shut off the main water valve and call a plumber immediately.

Conclusion

So—should you call a plumber for frozen pipes? If there’s any doubt, yes. While minor, visible freezes can often be handled safely at home, hidden damage or complex plumbing setups demand professional expertise. A $200 service call could save you $15,000 in water restoration and structural repairs.

Don’t gamble with your home’s plumbing this winter. Share this guide with friends and family—especially those in cold-climate states—so they’re prepared before the next freeze hits.
