The cheapest way to deal with a frozen pipe in Rapid City is to keep it from freezing in the first place. A burst pipe repair often runs $350 to $1,500, and the water damage behind it can cost far more. A few simple winter habits cost almost nothing and prevent most of it. Here is exactly what to do.
Why Pipes Burst in the Black Hills
Water expands as it freezes. When a pipe full of water freezes, the ice builds pressure against the pipe walls and the closed sections of pipe until something splits. The split often is not where the ice formed, but downstream, where pressure has nowhere to go.
In the Black Hills, winters drop to 20 below, and the pipes most at risk are the ones with the least protection:
- Pipes in exterior walls
- Pipes in unheated crawlspaces and basements
- Pipes in garages, sheds, and unheated outbuildings
- Water lines on rural acreage around Piedmont, Hermosa, and Wall
Vacant cabins around Hill City and Custer are the worst case. A pipe can freeze, burst, and pour water for days before anyone arrives.
Before the Cold: Winterize Your Plumbing
A little fall prep prevents most winter bursts.
- Disconnect garden hoses and shut off and drain outdoor faucets. A connected hose traps water in the spigot, which freezes and cracks the line.
- Insulate exposed pipes in crawlspaces, basements, garages, and exterior walls with foam pipe sleeves or heat tape.
- Seal drafts near pipes. Cold air pouring through a gap in the rim joist or foundation can freeze a pipe even when the room feels fine.
- Know where your main shutoff is before you need it, and make sure it turns freely.
During a Cold Snap: Daily Habits
When the forecast drops well below zero, these habits keep water moving and warm.
- Let a faucet drip. Moving water is far harder to freeze. A slow drip on the faucet farthest from where the water enters the house keeps the whole run flowing.
- Open cabinet doors under sinks on exterior walls so warm room air reaches the pipes.
- Keep the heat on, even when you are away. Never set it below 55 degrees in winter.
- Open interior doors so heat circulates to colder rooms.
For Vacant Cabins and Second Homes
If a property will sit empty through winter, the surest protection is to take the water out of the pipes entirely:
| Step | Why It Matters | | --- | --- | | Shut off the main water supply | No water in the lines means nothing to freeze | | Drain the pipes and water heater | Removes the water that would otherwise burst the line | | Add antifreeze to drain traps | Keeps trap water from freezing and cracking fittings | | Keep heat at a safe minimum | Backup protection for anything still holding water |
This is the same approach we recommend for the many seasonal cabins around Hill City, Custer, and Deadwood.
What to Do If a Pipe Freezes
If you turn on a faucet and only a trickle comes out, you may have a frozen pipe that has not burst yet. Act fast:
- Leave the faucet open. As the pipe thaws, running water helps melt the ice.
- Warm the pipe gently with a hair dryer, a space heater, or warm towels. Never use an open flame.
- Find the main shutoff in case the pipe has already cracked and water starts flowing once it thaws.
If a pipe has already burst, shut off the main water valve immediately and call a plumber. Our 24/7 emergency line answers any hour at (605) 555-0900.
The Bottom Line
Frozen pipes are one of the most common and most preventable plumbing emergencies in Rapid City. Winterize in the fall, let faucets drip in deep cold, keep the heat on, and drain the lines in any home that sits empty. Do those things and you will likely skip the burst pipe repair entirely.
