Frozen Pipes Plumber: What the Pros Do and When to Call One
If a line has already split and water is coming out, stop reading and do two things: close the main valve at the point where the supply enters your home (look near the meter), and kill the breaker for any area where water is nearing outlets, cords, or the panel, before you touch anything wet.
Frozen but not leaking? Do this now:
- Open the faucet the frozen line feeds. An open tap bleeds off the pressure trapped in the line and lets meltwater escape as the ice recedes.
- Locate the main shutoff and test that it actually moves. If the pipe lets go during thawing, you want that valve already located.
- Look over the coldest runs (crawl space, garage, exterior walls) for frost, bulges, or hairline cracks.
- Apply low, steady heat: a hair dryer worked along the run, a heating pad strapped around it, or a space heater positioned a safe distance from anything that could ignite. Never a torch or any open flame.
- No flow after an hour, or the freeze is somewhere you can't reach? That's the point where the job belongs to a pro.

Can a Plumber Fix Frozen Pipes?
Yes, and usually faster than a homeowner working with a hair dryer. A licensed plumber will:
- Locate the ice plug with supply-layout knowledge and thermal tools instead of guesswork. (Want to try first? See how to find where pipes are frozen.)
- Thaw the line in a controlled way, watching pressure so a hidden split doesn't flood the room the moment ice releases.
- Test the line before leaving. Ice can crack copper or plastic without leaking until it melts, so pros restore pressure gradually and check every joint they warmed.
- Repair any damage on the spot. A split section is cut out and replaced in the same visit in most cases.
How Plumbers Thaw Frozen Pipes
The answer to "what do plumbers use" depends on the material:
- Pipe-thawing machines pass a low-voltage current through copper or galvanized steel, warming the frozen section from within with no wall demolition. Metal lines only.
- Heat guns and infrared heaters handle accessible runs in basements and crawl spaces.
- Warm-air methods work on PEX and CPVC, which can't take current and shouldn't take direct high heat.
- A small, planned access cut in drywall beats the alternative: waiting for the ice to win and opening the whole ceiling for water damage instead.

What a Frozen Pipes Plumber Costs
Almost nobody in this niche publishes numbers, so here are the researched ranges:
| Scenario | Typical cost |
|---|---|
| Thawing an accessible frozen line, nothing burst | $100-$200 flat (Angi, 2025-2026 pricing) |
| Deep or hard-to-reach freeze (under slab, behind finished walls) | up to ~$500 |
| Split before the thaw, repair plus water damage | $13,954 average insurance claim for water damage and freezing (Insurance Information Institute, 2018-2022 claims) |
That gap, a couple hundred dollars versus a five-figure claim, is the honest math behind calling early. Full repair pricing is broken down in our frozen pipe repair cost guide.
Should You Just Wait for a Thaw?
Frozen pipes do eventually thaw on their own once temperatures climb. The catch: while you wait, ice keeps expanding, and pressure builds between the plug and your closed faucets. A freeze that holds for days is exactly the kind that ends in a split, and nobody's home watching when it lets go.
One more myth worth killing: nothing you pour down a drain will unfreeze a supply run. Drain additives never touch the pressurized line where the ice actually is. If you want to work the problem yourself, start with our step-by-step thawing guide and the full first-hour checklist.
Call Right Now If You See Any of These
- A bulge, crack, or frost-caked section, even if nothing is leaking yet
- Frozen for more than a day, or a freeze inside a wall or ceiling
- No water at every fixture in the house (the freeze may be on the main service line)
- Water stains, or a water meter that moves after thawing with every faucet closed
One honest note about "24/7": partner plumbers answer day and night in winter, but during a regional cold snap everyone's pipes freeze the same week, so arrival windows stretch. Calling a plumber for frozen pipes early beats calling desperate. (800) 555-0173: a free call that finds a frozen pipes plumber near you.
