Frozen Pipe Repair in Germantown & Rockville, MD: What Homeowners Need to Know

It can be startling when a faucet suddenly stops running. Sometimes it means a pipe has frozen.

If you have plumbing in Germantown or Rockville, both in Montgomery County, this guide explains how pipes freeze, what to watch for, and when frozen pipe repair is the safest next step.

How a Pipe Freezes and Splits

Water expands as it freezes. Live Science explains that ice pushes the remaining water toward a closed faucet, so pressure builds between the blockage and the faucet. That is usually where the pipe splits. Sections upstream of the ice are generally safe, because the water there can flow back toward its source. The typical danger point is around 20°F.

Which Pipes Are Most at Risk

Pipes in places that stay cold are the most exposed, including:

Attics and crawl spaces
Pipes along outside walls
Unheated or minimally heated areas
Outdoor hose connections

Pipes inside cabinets can be exposed too, which is why WSSC Water suggests opening cabinet doors during a cold spell.

Warning Signs to Watch For

A faucet that runs slowly or stops running is the classic early clue, and it is worth acting on right away. After a thaw, water can escape through a split, so also watch for:

Unexplained wet spots
Low water pressure
The sound of running water when everything is off

What to Do When a Pipe Freezes

WSSC Water suggests these steps, in this order:

Fully open the cold faucet nearest the frozen pipe to relieve pressure.
Know where your main shut-off valve is before you start.
Thaw the pipe carefully with a hair dryer, because it may split and spray water.
