Why frozen pipe repair is different in Minnesota
Deep frost
Frost penetrates deeply in Minnesota winters, and shallow or poorly insulated service lines can freeze underground, leaving a home with no water.
Rim joist and exterior-wall pipes
Basement pipes running along rim joists and supply lines in exterior walls are the most frequent freeze points in Minnesota homes.
City run-water advisories
During extreme cold, some cities notify specific properties with a history of frozen service lines to keep a faucet running to prevent freezing.
Vacant and seasonal properties
Cabins and vacant homes left unheated, or heated too low, freeze quickly; they should be winterized or monitored.
How it varies across Minnesota
| Region | What to expect |
|---|---|
| Twin Cities | Older Minneapolis and St. Paul homes have many rim joist and exterior-wall pipes, and frozen service lines occur during long cold snaps. |
| Northern Minnesota | Longer, colder winters and many seasonal cabins make winterization and heat tape especially important. |
Homeowner vs. utility responsibility
Usually the homeowner
- Pipes inside the home and the private portion of the service line
- Keeping the home heated and following any run-water advisory
Usually the utility
- The public main and, in some cities, part of the service line
- Run-water advisories and, in some cities, help thawing frozen service lines
Exact boundaries vary by utility and city. Check with your local provider before planning work.

What our plumbers do
- Open the affected faucet so melting water can flow and relieve pressure.
- Apply gentle heat working from the faucet back toward the frozen section: a hair dryer, warm towels, or a space heater kept a safe distance from flammable materials.
- Open cabinet doors to let warm room air reach pipes on exterior walls.
- Once flow returns, check the full length of the pipe for leaks.
- If the pipe is inaccessible or does not thaw, a plumber may use specialized thawing equipment or open access.
Frozen Pipe Repair in Minnesota cities
Frozen Pipe Repair in Minnesota: questions
What should I do if my pipes freeze in Minnesota?
Open the affected faucet, apply gentle heat such as a hair dryer or space heater with care, and never use an open flame. If you can’t find the frozen spot or a pipe has split, shut off the main and call for help.
What if my water service line is frozen underground?
Contact your city water utility first; some cities help thaw service lines. A plumber with specialized equipment can thaw lines that are on the private side.
Should I keep a faucet running during Minnesota cold snaps?
If your city has advised your property to run water, follow its instructions. Otherwise, dripping faucets on exterior walls can help in extreme cold.
How do I prevent rim joist pipes from freezing?
Insulate and air-seal the rim joist area, insulate the pipes, and keep the basement heated. Moving pipes away from exterior walls is the permanent fix.
How should I winterize a Minnesota cabin?
Shut off the water, drain the system, blow out lines if needed, add RV antifreeze to traps and drain the water heater.
