Leaks, pipes & freezing · Saint Paul

Frozen pipe thawing in Saint Paul, MN

If a faucet gives no water or only a trickle after a hard freeze, a pipe is frozen. Leave that faucet open, warm the area gently, and call a plumber if you can't find the frozen section or if it's inside a wall, because a split pipe will leak as soon as it thaws.

Frozen pipe thawing for Saint Paul homes

Cold snaps can arrive fast. An arctic front can drop temperatures 30 to 40 degrees in an afternoon, and pipes in exterior walls, garages, crawl spaces and over unheated soffits freeze first. Homes with pipes run along north-facing walls, or kitchens over a garage, see the same freeze every winter.

For the full guide, including what you can safely do before a plumber arrives, see frozen pipe thawing explained.

Local conditions

Frozen pipe thawing in Saint Paul: what's different

Saint Paul's very cold winters freeze pipes near exterior walls and in basements of Victorian and early 1900s homes in Summit Hill and Mac-Groveland. Extreme cold can also freeze buried water service lines.

A plumber thaws frozen interior lines without open flame and checks for splits. Frozen service lines need special equipment, and Saint Paul Regional Water Services advises residents on preventing them during extreme cold.

Sealing rim joists, insulating pipes on exterior walls and keeping heat on in every room prevent most freezes. Permits come from the City of Saint Paul Department of Safety and Inspections (DSI).

How frozen pipe thawing works in Saint Paul

  1. 1

    Locate the freeze

    The plumber traces the line from the dead fixture back toward the main, checking exterior walls, garage ceilings and crawl spaces.

  2. 2

    Thaw safely

    Controlled heat such as a heat gun, heat tape or an electric pipe thawing machine is used. Never an open flame.

  3. 3

    Check for splits

    As water starts to move, the section is watched for leaks before the faucet is closed and full pressure builds.

  4. 4

    Prevent the next one

    Options include insulation, heat cable, sealing air leaks around the rim joist, or moving the pipe into a heated space.

What affects frozen pipe thawing cost in Saint Paul

  • How easy the frozen section is to reach
  • Whether the line split while frozen

Frozen pipe thawing questions in Saint Paul

What if my Saint Paul water service line freezes?

Call Saint Paul Regional Water Services and a plumber. Frozen service lines need special thawing equipment.

Should I drip my faucets in a cold snap?

Yes, for faucets on exterior walls. A slow drip relieves pressure and keeps water moving. Open both hot and cold on single-handle faucets, and open the cabinet doors underneath.

How long does it take a pipe to freeze?

An unprotected pipe in an unheated space can freeze within a few hours once temperatures fall into the low 20s °F, especially with wind. Pipes inside heated walls take much longer.

Can a frozen pipe thaw on its own without damage?

Sometimes, but you won't know whether it split until it thaws. Keep the faucet open and watch the area closely, with the main shutoff within reach.
