How Much Does a Plumber Charge to Unfreeze Pipes?

There’s nothing more stressful than waking up to no water—or worse, a burst pipe—on a freezing winter morning. If you’re asking, “How much does a plumber charge to unfreeze pipes?”, you’re not alone. Many U.S. homeowners face this urgent issue each year, especially in colder states like Minnesota, Colorado, or New York. The good news? Understanding typical costs, response times, and prevention strategies can save you both money and major headaches. Let’s break it all down clearly and compassionately—because frozen pipes don’t wait, and neither should your peace of mind.

What Causes Pipes to Freeze?

Before diving into costs, it helps to understand why pipes freeze in the first place. Water expands when it freezes, creating immense pressure inside pipes. If that pressure isn’t relieved, the pipe can crack or burst—even if the ice later thaws.

Common risk factors include:

• Pipes located in unheated areas (attics, garages, basements)
• Poor insulation around plumbing
• Sub-zero temperatures lasting more than 6 hours
• Thermostats set too low during cold snaps

According to the Insurance Institute for Business & Home Safety, a single burst pipe can cause over $5,000 in water damage—not including repair labor. That’s why acting fast matters.

How Much Does a Plumber Charge to Unfreeze Pipes? (2025 Pricing)

The average cost to unfreeze pipes ranges from $100 to $400, depending on several key factors:

Most plumbers charge $75–$150 per hour, with a minimum service fee of $75–$125 just for showing up. If your pipes are frozen but not yet damaged, many pros can thaw them in 30–90 minutes using specialized tools like infrared heaters or pipe-thawing machines.

💡 Pro Tip: Some plumbing companies offer flat-rate pricing for frozen pipe emergencies (e.g., “$249 for same-day thawing”). Always ask for a quote upfront.

DIY vs. Hiring a Plumber: What’s Safer?

You can try thawing minor freezes yourself—but only if you’re 100% sure the pipe hasn’t burst. Here’s a safe, step-by-step method:

1. Turn on the faucet – This relieves pressure and lets water flow as ice melts.
2. Apply gentle heat – Use a hair dryer, heating pad, or warm towels. Never use open flames (like a torch)—this risks fire or pipe damage.
3. Work from faucet toward blockage – Heat the nearest accessible section first.
4. Monitor for leaks – If you see water pooling, stop immediately and call a pro.

⚠️ Warning: If pipes are inside walls, under floors, or made of PVC/CPVC, DIY attempts can worsen damage. When in doubt, call a licensed plumber.

Hidden Costs to Watch For

Even if the thawing itself costs $150, additional expenses may arise:

• Water damage restoration: $500–$5,000+ if walls or flooring are soaked
• Pipe replacement: $200–$1,500 if a section cracked
• Mold remediation: $500–$6,000 if moisture lingers untreated

A 2024 HomeAdvisor survey found that 68% of frozen pipe emergencies led to secondary repairs—so prevention is far cheaper than cure.

How to Prevent Frozen Pipes This Winter

Avoid the stress (and bill) entirely with these proven strategies:

✅ Insulate pipes in attics, crawl spaces, and garages with foam sleeves ($0.50–$2/ft)
✅ Keep garage doors closed and interior doors open to allow warm air circulation
✅ Let faucets drip at 5–10 drops per minute when temps drop below 20°F
✅ Set thermostat no lower than 55°F when away during winter

The U.S. Department of Energy estimates that proper insulation can reduce freeze risk by up to 90%.

Emergency Response: What to Do Right Now

If you suspect frozen pipes:

1. Check for no water flow or reduced pressure at faucets
2. Feel pipes for cold spots (especially on exterior walls)
3. Shut off main water valve if you see swelling, frost, or leaks
4. Call a licensed plumber immediately—delaying can turn a $150 fix into a $3,000 disaster

Many plumbing companies offer 24/7 emergency service. Save a local pro’s number in your phone before winter hits.

FAQ: Your Top Questions Answered

Q: Can frozen pipes thaw on their own?

A: Yes—but it’s risky. As ice melts, pressure builds. If the pipe is already cracked, water will gush out unnoticed, causing hidden damage. Controlled thawing by a pro is far safer.

Q: How long does it take a plumber to unfreeze pipes?

A: Typically 30–90 minutes for accessible pipes. Complex cases (e.g., pipes in walls) may take 2–4 hours, especially if drywall needs temporary removal.

Q: Does homeowners insurance cover frozen pipe damage?

A: Yes, usually—but only for resulting water damage, not the plumbing repair itself. You’ll still pay the plumber. Always document damage with photos and file a claim promptly.

Q: Are PEX pipes less likely to freeze?

A: PEX is more flexible than copper or PVC and can expand slightly, reducing (but not eliminating) burst risk. However, water inside can still freeze and block flow.

Q: What’s the cheapest way to unfreeze a pipe?

A: If safe, use a hair dryer ($0 cost if you own one) or electric heating pad. But again—only attempt if you’re certain there’s no rupture.

Q: How cold does it have to be for pipes to freeze?

A: Generally, below 20°F for 6+ hours. However, poorly insulated pipes can freeze at higher temps—especially in drafty areas.

Conclusion

Knowing how much a plumber charges to unfreeze pipes empowers you to act fast, avoid panic pricing, and protect your home. While DIY methods work in mild cases, professional help ensures safety, speed, and long-term reliability—especially during freezing emergencies.

Don’t wait for disaster. Insulate your pipes, keep faucets dripping in deep cold, and save a trusted plumber’s number today.
