How to Thaw Frozen Pipes in Alaska
Open the faucet
Open both hot and cold handles on the faucet the pipe leads to. This allows water to flow once ice melts and relieves pressure.
Locate the frozen section
Feel along the pipe for extremely cold spots. Check pipes in exterior walls, near windows, and in unheated areas.
Apply heat starting at the faucet
Use a hair dryer, heat lamp, or space heater. Work from the open faucet toward the frozen area. Never use open flames.
Continue until flow returns
Keep applying heat until full water pressure is restored. This can take 30 minutes to 2 hours.
Check for leaks
Once thawed, carefully inspect the entire pipe for cracks or leaks. Freezing can cause hidden damage.
Never Do These Things
- • Never use a propane torch or open flame
- • Never pour boiling water on pipes
- • Never use a kerosene heater indoors
- • Never ignore a bulging pipe — it's about to burst

Preventing Frozen Pipes in Alaska
Frequently Asked Questions
How do I know if my pipes are frozen in Alaska?
Signs of frozen pipes include: no water or very low water pressure from faucets, frost visible on exposed pipes, strange smells from drains (trapped sewage), and bulging or cracked pipes. In Alaska winters (-20°F to 20°F), pipes in exterior walls, crawl spaces, and unheated areas freeze first.
How much does it cost to fix frozen pipes in Alaska?
Thawing frozen pipes costs $200 - $550 in Alaska. If the pipe bursts, repair costs range from $300 - $900 for accessible pipes, or more for pipes in walls or underground. Emergency/after-hours service adds 50-100% to these costs.
At what temperature do pipes freeze in Alaska?
Pipes can begin freezing when outdoor temperatures drop below 20°F (-6°C). In Alaska, this commonly occurs October through April. Pipes in unheated areas like crawl spaces, attics, and exterior walls freeze fastest. Wind chill makes it worse.
Can I thaw frozen pipes myself in Alaska?
You can safely thaw accessible frozen pipes using a hair dryer, heat lamp, space heater, or warm towels. Never use open flames, propane torches, or boiling water—these can crack pipes or start fires. If pipes are in walls or you see bulging/cracks, call a Alaska plumber immediately.
How long does it take for pipes to freeze in Alaska?
In Alaska's winter cold (-20°F to 20°F), unprotected pipes can freeze in as little as 4-6 hours. During extreme cold events, pipes can freeze in 2-3 hours. Interior pipes in heated homes rarely freeze unless heat fails.
Should I let my faucets drip to prevent frozen pipes in Alaska?
Yes, letting faucets drip during extreme cold prevents frozen pipes. The constant water movement makes freezing harder, and the open faucet relieves pressure if freezing occurs—preventing bursts. This is especially important in Alaska October through April.
What do I do if a frozen pipe bursts in Alaska?
Immediately shut off your main water valve. Then call an emergency plumber in Anchorage or your area. While waiting: turn off electricity to affected areas, remove valuables from water, and document damage with photos for insurance.
Does homeowners insurance cover frozen pipe damage in Alaska?
Most Alaska homeowners insurance covers water damage from burst pipes if you maintained reasonable heat in your home. Coverage typically includes repairs and water damage restoration. However, the pipe repair itself may not be covered. Check your policy and document everything.
