Call a licensed plumber immediately if your pipes freeze. A professional plumber has the exact machinery and experience needed to thaw your lines without causing a catastrophic burst.
When sub-zero temperatures hit, you need to know who to call for frozen pipes before minor ice turns into a massive, expensive flood. Acting quickly and contacting a licensed local professional like Derks Plumbing will protect your home from severe water damage.
What Happens When Pipes Freeze?
When water freezes, it does something unusual: it expands. Inside a copper, PEX, or galvanized steel pipe, this expansion creates immense hydraulic pressure. The ice blockage itself is not what typically ruptures the pipe. Instead, the ice pushes water toward closed faucets or bends in the plumbing, trapping it.
This trapped water gets compressed by the growing ice. The pressure climbs until the metal or plastic pipe wall splits open. When the temperature rises and the ice block thaws, water rushes out of the split at full household pressure, flooding your crawl spaces, ceilings, and floors.

Who Should You Call for Frozen Pipes?
A licensed plumber is who fixes frozen pipes safely and correctly. Here’s why that matters more than trying a DIY approach.
Plumbers carry tools designed to thaw pipes without damaging them. They also know how to check for hidden cracks before you turn the water back on. A crack you can’t see can flood your home once water starts flowing again.
If you’re searching for plumber frozen pipes services, look for a company with emergency availability. Frozen pipes often happen during nights, weekends, or holidays when temperatures drop fastest. A plumber who answers calls around the clock can prevent a small freeze from turning into major water damage.
Some homeowners also call their water utility company first, especially if the frozen section is part of the main line rather than interior plumbing. But for pipes inside your home, a plumber is almost always the right first call.
Signs Your Pipes Are Frozen
Catching a frozen pipe early can prevent a burst. Watch for these warning signs.
- No water or a weak trickle from a faucet that normally runs fine
- Frost visible on exposed pipes, especially in basements or crawl spaces
- Strange smells coming from a drain or faucet, which can mean a blockage from ice
- Bulging or swollen sections of visible pipe
- Unusual banging or clanking noises in your plumbing system
If you notice any of these signs, don’t wait. Call a plumber before the pressure builds high enough to crack the pipe.
What to Do Before the Plumber Arrives
While you wait for your professional to pull up to your property, take these protective steps to minimize damage:
Shut Off the Main Water: Locate your main water shut-off valve (usually in the basement, utility closet, or near the street) and close it completely.
Open Faucets: Turn on the taps connected to the frozen lines. This relieves the hydraulic pressure as the ice begins to melt.
Clear the Area: Move furniture, electronics, and valuables away from walls or ceilings where you suspect frozen pipes are located.
Document Everything: Take photos of any visible frost, bulging areas, or active leaks for insurance purposes.
What a Plumber Does to Fix Frozen Pipes
Professional plumbing repair for frozen pipes usually follows a clear process.
Step 1: Locate the Frozen Section
Plumbers use moisture meters, thermal cameras, or a process of elimination based on where water flow has stopped.
Step 2: Thaw the Pipe Safely
Plumbers use tools like heat tape, hot water wraps, or specialized heat guns designed for gradual, even thawing. This prevents the rapid temperature change that can crack already-stressed pipe walls.
Step 3: Inspect for Damage
Once thawed, the plumber checks the full length of the pipe for cracks, splits, or weak spots that might fail later.
Step 4: Repair or Replace Damaged Sections
If damage is found, the plumber repairs the specific section rather than replacing the entire line, which keeps repair costs lower in most cases.
Step 5: Test Water Flow and Pressure
Before finishing the job, the plumber restores water flow and checks for leaks at every joint and connection near the repair.
Can You Thaw Frozen Pipes Yourself?
You can attempt to thaw a pipe yourself only if the line is fully exposed, easily accessible, and has no visible cracks.
Never use an open flame, propane torch, or space heater. These tools pose extreme fire risks and can cause the water inside the pipe to boil rapidly, triggering a violent explosion. Instead, use a handheld hair dryer on a low setting or wrap the pipe in towels soaked in hot water. Always start warming from the faucet side and work your way back toward the frozen blockage to let steam escape safely.
What If a Frozen Pipe Bursts?
If a pipe has already split, you are dealing with an urgent plumbing emergency. Follow these steps immediately:
Cut the Water and Power: Shut off the main water valve instantly. If water is near electrical outlets or your breaker box, safely turn off the electricity to those zones.
Call for Emergency Repairs: Contact an emergency plumbing repair for frozen pipes specialist right away.
Remove Standalone Water: Use a wet-dry vacuum, mop, and towels to extract as much standing water as possible to prevent mold growth.
Call Your Insurer: Report the burst pipe to your homeowner’s insurance company to start the remediation claim.
How Much Does It Cost to Repair Frozen Pipes?
The cost to resolve frozen plumbing varies depending on whether the line is simply frozen or has already burst.
On average, professional thawing services range from $200 to $600. If the pipe has burst and requires structural drywall removal, line replacement, and water damage restoration, the cost can quickly climb to $1,500 or more. Investing in timely professional plumbing frozen pipes services prevents these expensive complications.
How Long Does It Take to Fix Frozen Pipes?
For standard, accessible lines, a professional plumber can thaw a frozen section in 1 to 3 hours.
If the frozen section is deep inside a finished wall, floor, or ceiling, the diagnostic and repair process can take 4 to 8 hours. The total duration depends heavily on how early you identify the issue and contact professional help.
How to Prevent Pipes from Freezing Again
Preventative care is the best defense against winter plumbing disasters. Implement these habits before the cold weather returns:
Insulate Your Pipes: Wrap exposed lines in unheated areas (crawl spaces, attics, and garages) with high-quality foam sleeve insulation.
Drip Your Faucets: When temperatures drop below freezing, let a very slow drip of cold water run from your furthest faucets. Moving water is much harder to freeze.
Keep Cabinet Doors Open: Open the doors under your kitchen and bathroom sinks to allow warm home air to circulate around the plumbing.
Seal Air Leaks: Use expanding foam or caulk to seal gaps near outdoor vents, cable lines, or sill plates where freezing air drafts enter.
When Frozen Pipes Become a Plumbing Emergency
A frozen pipe turns into an active emergency the moment you see water leaking, hear rushing water behind walls, or notice severe bulging along a metal or plastic line. Do not wait for the line to thaw on its own. The pressure buildup can cause sudden, catastrophic damage to your home’s structural foundation and electrical systems.
Why Hiring a Licensed Plumber Matters
