Leaks, pipes & freezing · Thornton
Frozen pipe thawing in Thornton, CO
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 Thornton 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.

Local conditions
Frozen pipe thawing in Thornton: what's different
Thornton sits on open plains with little to break the wind during cold fronts, so garages, crawl spaces and exterior walls lose heat fast. Pipes in garage ceilings and along north walls freeze first.
A plumber thaws the frozen section safely, checks for splits, and looks at insulation and air sealing. Newer homes with PEX tolerate freezing better but still fail at fittings.
In Original Thornton's 1950s ranches, supply lines in crawl spaces and along basement rim joists are the usual trouble spots. In newer north Thornton homes, lines in garage ceilings under bonus rooms freeze first when an arctic front settles in.

How frozen pipe thawing works in Thornton
- 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
Thaw safely
Controlled heat such as a heat gun, heat tape or an electric pipe thawing machine is used. Never an open flame.
- 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
Prevent the next one
Options include insulation, heat cable, sealing air leaks around the rim joist, or moving the pipe into a heated space.
