How to Prevent Your Pipes From Freezing This Winter (And What to Do If They Already Have)

Winter in Onslow County may not be as harsh as up north, but we still get freezing nights—especially in January and February—when temperatures can drop suddenly. Those quick cold snaps catch homeowners off guard every year, and one of the most common (and costly) problems we see is frozen or burst pipes.

A frozen pipe isn’t just inconvenient. It can lead to major water damage, expensive repairs, and days without running water. Fortunately, most frozen pipe issues can be prevented with a few simple steps.

Here’s what every homeowner in Jacksonville, Richlands, Sneads Ferry, Swansboro, and surrounding areas should know this winter.

Why Pipes Freeze in Eastern North Carolina

You might think freezing pipes are only a northern problem, but coastal NC homes often have:

• Exposed or poorly insulated pipes, especially in crawlspaces
• Older homes built before current insulation standards
• Pipes running along exterior walls where cold air seeps in
• Outdoor hose bibs left unprotected

When the air dips below 32°F, the water inside these pipes can freeze, expand, and eventually cause the pipe to crack or burst.

How to Tell if Your Pipes Are Freezing

Watch for these early warning signs:

• Little or no water pressure
• Frost on the outside of pipes
• Strange smells coming from faucets or drains (a sign the pipe is partially blocked by ice)

If you notice these symptoms, shut off your water immediately and call a professional.

What to Do If Your Pipes Already Froze

If you suspect a frozen pipe, act fast:

1. Turn off the main water supply to prevent flooding if the pipe bursts.
2. Open the faucet connected to the frozen line.
3. Use gentle heat—like a hair dryer or space heater—on the affected pipe.
   Never use open flames or high-heat tools.
4. Call a licensed plumber if you can’t reach the frozen section or if you’re unsure where the freeze is.

Even if the pipe thaws, damage may have already occurred. A professional can inspect it to ensure it’s safe.

When to Call a Plumber

Reach out to a professional immediately if:

• You think a pipe is frozen and can’t locate it
• The pipe has visible cracks
• Water isn’t flowing after thawing
• You notice dripping, moisture, or pooling water

In Onslow County, freezing nights can hit fast. A quick response can prevent big repair bills.
