Should I Call a Plumber for Frozen Pipes? Here’s What to Do

Waking up to no running water on a freezing winter morning is more than just an inconvenience—it’s a potential disaster in the making. If you’re wondering, “Should I call a plumber for frozen pipes?” you’re not alone. Thousands of U.S. homeowners face this dilemma every winter, often unsure whether they can handle it themselves or need professional help. The truth? Acting quickly—and correctly—can mean the difference between a minor fix and thousands in water damage. Let’s break down exactly what to do, when to act, and when it’s time to pick up the phone.

How Do Pipes Freeze—and Why It Matters

Pipes freeze when ambient temperatures drop below 32°F (0°C) for several hours, especially in unheated areas like attics, garages, or exterior walls. According to the Insurance Institute for Business & Home Safety (IBHS), a single burst pipe can cause over $5,000 in water damage—and that’s before mold remediation or structural repairs.

Frozen pipes don’t just stop water flow—they create dangerous pressure buildup. As ice expands inside the pipe, it can crack metal or PVC, leading to a burst pipe the moment the ice thaws. That’s why timing and technique matter more than you think.

💡 Did you know? The U.S. Department of Energy notes that pipes in unheated spaces can freeze in as little as 6 hours during sub-zero temperatures.

Can You Thaw Frozen Pipes Yourself? (And When You Shouldn’t)

✅ Safe DIY Thawing: When It’s Okay to Try

If you know exactly where the freeze is, the pipe isn’t cracked, and you have safe access, you might thaw it yourself. Common signs of a frozen pipe include:

• No water (or just a trickle) from a faucet
• Frost or bulging on visible pipes
• Unusual smells from drains (due to trapped air)

Step-by-step safe thawing method:

1. Turn on the faucet. This relieves pressure and lets water flow as ice melts.
2. Apply gentle heat using one of these methods:
   • Hair dryer (keep moving to avoid overheating)
   • Electric heating pad wrapped around the pipe
   • Towels soaked in warm (not boiling!) water—around 110°F (43°C)
3. Work from the faucet toward the blockage. This prevents steam pressure from trapping behind the ice.
4. Never use open flames (torches, lighters) or boiling water—they can melt PVC or ignite nearby materials.

⚠️ Warning: If you see any moisture, cracks, or bulges, stop immediately. A compromised pipe could burst during thawing.

❌ When to Call a Plumber Immediately

Call a licensed plumber right away if:

• You can’t locate the frozen section
• The pipe is behind a wall or in a crawlspace
• You notice any signs of leakage (even a small drip)
• You’ve tried DIY methods for over 30 minutes with no results
• Outdoor temperatures are below 20°F (-6°C)—risk of re-freezing is high

Professional plumbers use infrared cameras and pipe-thawing machines that safely deliver controlled heat without damaging your system—tools most homeowners don’t have.

Frozen Pipe Emergency: What Happens If You Wait?

Delaying action is the #1 mistake homeowners make. A study by State Farm Insurance found that 25% of winter water damage claims stem from delayed responses to frozen pipes.

Consider this real case:
In January 2023, a family in Minnesota ignored a slow drip from their kitchen faucet during a cold snap. Within 48 hours, the pipe burst behind the wall, flooding the kitchen and subfloor. Repairs totaled $18,000—including drywall replacement, flooring, and mold treatment.

Compare that to the $150–$300 average cost for a plumber to thaw a frozen pipe before it bursts (HomeAdvisor, 2024 ).

DIY vs. Pro: Quick Comparison

📌 Pro Tip: Even if you thaw the pipe yourself, have a plumber inspect it within 24 hours. Micro-cracks may not leak immediately but can fail days later.

How to Prevent Frozen Pipes Next Winter

Prevention is far cheaper than repair. The EPA’s WaterSense program recommends these proven strategies:

• Insulate pipes in unheated areas with foam sleeves (R-3 to R-5 rating)
• Keep garage doors closed and seal cracks near pipes
• Let faucets drip at 5–10 drops per minute when temps drop below 20°F
• Set thermostat no lower than 55°F when away in winter
• Open cabinet doors under sinks to allow warm air circulation

For long-term protection, consider installing heat tape (thermostatically controlled) on vulnerable pipes—available at hardware stores for under $50.

FAQ: Should I Call a Plumber for Frozen Pipes?

Q1: How long does it take for a plumber to fix frozen pipes?

A: Most plumbers can thaw and inspect a frozen pipe in under an hour. If a pipe has burst, repairs may take several hours or require follow-up visits for drying and restoration.

Q2: Will my homeowner’s insurance cover frozen pipe damage?

A: Yes—but only if you took reasonable precautions. Insurers often deny claims if you left the heat off or failed to insulate pipes. Always document your prevention efforts.

Q3: Can frozen pipes thaw on their own?

A: Technically, yes—but it’s extremely risky. As ice melts, pressure builds behind the blockage. Without an open faucet to relieve it, the pipe can burst suddenly, causing major flooding.

Q4: What temperature do pipes freeze at?

A: While 32°F is the freezing point of water, pipes typically freeze at or below 20°F—especially if exposed to wind or poor insulation. Duration matters: 6+ hours below 20°F significantly increases risk.

Q5: Is it safe to use a space heater to thaw pipes?

A: Only if used with extreme caution. Never leave a space heater unattended near pipes or flammable materials. A hair dryer or heating pad is safer and more targeted.

Q6: How do I know if my pipe has already burst?

A: Signs include water stains on walls/ceilings, damp carpet, sudden drops in water pressure, or a hissing sound near pipes. If you suspect a burst, shut off the main water valve immediately and call a plumber.

Final Thoughts: Don’t Gamble with Frozen Pipes

So, should you call a plumber for frozen pipes? If there’s any doubt—yes. The small upfront cost pales in comparison to the financial and emotional toll of water damage. Remember: time is water, and water is money.

If this guide helped you avoid a plumbing nightmare, share it with a friend or neighbor—especially someone in a colder climate. A quick share could save them thousands this winter.

Stay warm, stay dry, and when in doubt, call a pro. Your home (and wallet) will thank you.
