Winterizing Your Home in North Carolina: Avoid Frozen Pipes and Costly Damage

When winter arrives in North Carolina, it often brings surprises — mild one day, icy the next. But even one freezing night can lead to a homeowner’s worst nightmare: burst pipes, flooding, and expensive repairs. The good news? With just a few preventive steps, you can protect your home, your wallet, and your peace of mind.


Why Frozen Pipes Are a Real Threat in North Carolina

Because North Carolina winters are unpredictable, many homeowners don’t realize how vulnerable their plumbing can be. Unlike homes in colder states, most NC houses aren’t built with deeply insulated pipes. When temperatures drop suddenly, water freezes and expands inside the pipes — and that pressure can cause them to burst.

Problem areas to check:

  • Outdoor faucets and garden hoses
  • Crawl spaces and attics
  • Unheated garages and basements
  • Pipes near exterior walls


Essential Winterization Tips for North Carolina Homeowners

  1. Insulate Exposed Pipes -Use foam sleeves or heating tape to protect exposed pipes, especially in unheated areas.
  2. Seal Gaps and Cracks - Seal around windows, doors, and foundation walls to keep warm air inside.
  3. Let Faucets Drip During Freezes - A steady drip relieves water pressure and prevents burst pipes overnight.
  4. Open Cabinet Doors - Allow warm air to circulate under sinks, especially those on exterior walls.
  5. Keep the Thermostat Consistent - Even when away, maintain your home temperature at least 55°F.
  6. Drain Outdoor Faucets and Sprinklers - Disconnect garden hoses and shut off outdoor spigots before the first freeze.
  7. Inspect Attic and Crawl Space Insulation- Proper insulation reduces both heating costs and freezing risk.


🧊 Winter Prep Checklist for NC Homeowners:

✅ Disconnect and drain outdoor hoses
✅ Insulate exposed pipes in crawl spaces and attics
✅ Check crawl space vents for cold air leaks
✅ Seal foundation cracks
✅ Set thermostat to at least 55°F




What to Do If Your Pipes Freeze

If you turn on the faucet and nothing comes out, your pipe may already be frozen.

  1. Turn off your main water supply immediately.
  2. Use a hair dryer or heating pad to warm the affected pipe slowly.
  3. Never use an open flame to thaw pipes.

If you can’t locate the frozen area or suspect a burst, call a licensed plumber as soon as possible.


📍 Local Tip:

Even coastal areas like Wilmington and Morehead City experience freezing nights that can damage plumbing. In mountain towns like Boone or Asheville, frozen pipe issues are even more frequent — so early preparation is key.


Common Mistakes Homeowners Make When Winterizing

  • Turning off the heat completely while traveling
  • Forgetting to drain outdoor spigots
  • Ignoring drafty crawl spaces
  • Assuming “it won’t freeze this year”

💬 Did You Know?

Even one inch of frozen pipe can release over 250 gallons of water once it bursts — that’s enough to fill a small swimming pool inside your home.
