Metro Atlanta homes are built for mild winters, so their pipes are often underinsulated when a real freeze arrives, and that is exactly when they burst. The good news is that prevention here is cheap and simple: know your shutoff, protect the exposed pipes, and drip your faucets when a hard freeze is forecast. This post covers the practical steps, using the Christmas 2022 freeze as the local cautionary tale.
Why Georgia pipes are vulnerable
This is not Minnesota. Homes in Acworth are built for a climate that freezes only occasionally, so the plumbing is rarely insulated for a sustained hard freeze. When an Arctic blast does come through, the exposed lines are caught unprotected.
The most at-risk pipes are the ones in vented crawl spaces, in garages, and along exterior walls, plus outdoor hose bibs. Vented crawl spaces are the classic weak point, because the vents let cold air swirl around the pipes.
What the 2022 freeze taught the metro
Over Christmas 2022, metro Atlanta sat below freezing for three days, with about eight degrees on Christmas Eve morning. Cobb County fire crews were overwhelmed with burst-pipe calls, and county facilities including senior centers and a library were closed by the damage.
The key lesson: most bursts flooded after the thaw. A frozen pipe can crack while the ice plug still seals it, then let go when the water flows again. Prevention beats cleanup, because by the time water appears, the pipe has already failed.
The prevention checklist
Before winter, find your main shutoff and make sure it works, so you can stop water fast if a pipe does burst. Insulate exposed pipes in the crawl space, garage and along exterior walls with foam sleeves. Disconnect garden hoses and cover hose bibs, since an attached hose traps water that freezes back into the wall.
When a hard freeze is forecast, let a faucet drip, a slow trickle keeps water moving and relieves the pressure that actually splits a pipe. Open cabinet doors under sinks on exterior walls so warm air reaches the pipes, and keep the heat on even when away.
If a pipe freezes anyway
If no water comes out of a faucet during a freeze, a pipe is likely frozen. Keep that faucet open so melting water can escape, and warm the pipe gently if you can reach it, never with an open flame. Do not assume a thawed pipe is fine; a line that froze can leak once it thaws, so have it checked. And know where that shutoff is, because in a burst, minutes matter.
A simple room-by-room walk before winter
A short walk of the house in the fall catches most freeze risks. In the crawl space and garage, look for uninsulated pipe on exterior walls and add foam sleeves. At every outdoor spigot, plan to disconnect the hose and cover the bib. Under sinks on outside walls, remember that opening the cabinet doors during a freeze lets warm air reach the pipes.
Also confirm the main shutoff works and that everyone in the house knows where it is. The goal is to enter winter knowing your weak points and having them protected, rather than discovering them during the first hard freeze.
Traveling during a cold snap
An empty house is where freeze damage does the most quiet harm, because no one is there to notice a burst until it has run for hours. If you travel in winter, keep the heat on at a safe minimum rather than turning it off, and if possible have someone check the house.
During the 2022 freeze, some of the worst residential damage was in homes left unattended over the holidays. A thermostat kept at a safe level and a neighbor with a key are cheap protection against coming home to a flooded house.
The morning after: checking for damage
When a hard freeze breaks, the job is not over. Because pipes often crack while frozen and only leak on the thaw, the hours after temperatures rise are when to pay attention. Walk the house, run the faucets, and watch for reduced flow, damp spots or the sound of water where there should be none.
If a faucet ran dry during the freeze, keep it open as it thaws so melting water can escape, and warm the pipe gently rather than with a flame. And do not assume a line that thawed is fine; a pipe that froze can leak once water flows again, so a quick check the morning after is worth the few minutes it takes.
| When | Do this |
|---|---|
| Before winter. | Locate the main shutoff, insulate exposed pipe. |
| Before a freeze. | Disconnect hoses, cover bibs. |
| During a hard freeze. | Drip a faucet, open sink cabinets, keep heat on. |
| If a line froze. | Keep the faucet open, have the line checked after. |

Which pipes freeze first in Acworth?
The exposed ones: crawl-space lines on exterior walls, garage plumbing, and outdoor hose bibs. Those are the spots to insulate and to let drip when a hard freeze is forecast.
Does letting a faucet drip really help?
Yes. Moving water is harder to freeze, and the open faucet relieves the pressure that actually splits a pipe. It is one of the simplest and most effective freeze precautions.
My pipe froze but did not burst. Am I safe?
Not necessarily. A pipe can crack while frozen and only leak once it thaws and water flows again. If a line froze hard, have it checked before assuming it survived.
Should I leave the heat on when traveling in winter?
Yes. Keep the thermostat at a safe minimum and, if possible, have someone able to access the home. During the 2022 freeze, authorities urged travelers to arrange access in case pipes burst.
What is the single best freeze precaution?
Knowing and testing your main shutoff before winter, so you can stop water instantly if a pipe does burst. Alongside that, insulating exposed pipe and dripping a faucet during a hard freeze prevent most bursts in the first place.
Should I turn the heat off when traveling in winter?
No. Keep it at a safe minimum instead. An unattended house is where freeze bursts run longest before anyone notices. Some of the worst 2022 damage was in homes left empty over the holidays, so keep the heat on and, if you can, have someone check in.
Where to go from here
If a pipe does let go, burst pipe repair stops the damage and fixes the line. A burst that reached flooring and drywall needs water damage restoration afterward. A home that keeps breaking the same aging lines is a candidate for repiping.
