Frozen pipe thawing in Philadelphia, PA
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 Philadelphia 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 Philadelphia: what's different
Cold snaps freeze pipes in Philadelphia rowhouse basements and exterior walls. A plumber thaws the frozen section safely and checks for splits.
They also recommend insulation and sealing gaps where cold air gets in.
Rowhouses with pipes running along shared exterior walls or through unheated basements are especially vulnerable. Vacant rowhouses with heat turned off are a common source of bursts that also damage the neighboring property. After thawing, the plumber checks for splits and recommends insulating exposed runs, especially near basement windows and where pipes pass through exterior walls.

- Basement backups: Older combined sewers can back up into basements during heavy rain.

- Rowhouse shared lines: Some older rowhouses share sewer or water lines with neighbors, which complicates repairs and requires coordination between owners.
How frozen pipe thawing works in Philadelphia
- 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.
