Frozen pipes are the local emergency
Every plumber in this metro has a January that runs on frozen-pipe calls. Knowing the basics before it happens is worth real money, because the difference between a thaw and a burst is usually how fast someone acts.
- Know where your main shutoff is now, not during the emergency. Everyone in the house should know.
- If a faucet is running to a trickle in deep cold, that's often a pipe starting to freeze — not a plumbing quirk.
- Open under-sink cabinet doors on exterior walls during a cold snap so warm air reaches the pipes.
- Let a faucet drip on the coldest nights. Moving water is much harder to freeze.
- If a pipe has burst, shut the water off first and call second.

Frequently asked

As a 2026 ballpark, expect about $90–$200 for a service call and $85–$150 an hour, often with a one-hour minimum. Clearing a drain runs about $150–$450, and a tank water heater replacement about $1,200–$3,500 installed. After-hours rates are higher — ask in advance.
What should I ask a plumber before hiring?
Confirm they're licensed and insured in North Dakota. Ask whether the quote is flat-rate or hourly and what it includes. Ask about the warranty on the work itself, separate from the fixture. And for emergencies, ask their real response time and after-hours rate.
Do I need a permit for plumbing work in Bismarck?
Yes. The City of Bismarck lists plumbing among the work that requires a permit, and water heaters appear under the HVAC heading too. Your plumber should pull it. Call the Building Inspection Division at (701) 355-1465 if you're unsure about your specific job.
How do I prevent frozen pipes in North Dakota?
Insulate pipes in unheated areas, keep the house above 55°F even when you're away, and seal drafts near plumbing. On extreme-cold nights, let a faucet drip and open under-sink cabinet doors on exterior walls. Know where your main shutoff is before you need it.
What should I do first if a pipe bursts?
Shut the water off at the main, then call. Every minute the water runs adds to the damage, and the shutoff does more good in the first thirty seconds than anything a plumber can do over the phone. Make sure everyone in the household knows where that valve is.
