Frozen Pipes in Georgia? How to Prevent Them — and What to Do If One Bursts

People assume frozen pipes are a problem for up north. They’re not. North Georgia gets hard cold snaps every winter, and because homes here aren’t built for sustained freezing the way northern homes are, our pipes are often more exposed — running through uninsulated crawl spaces, garages, and exterior walls. A single hard freeze can burst a pipe, and a burst pipe can dump hundreds of gallons into your home in an hour.

The good news is that prevention takes about ten minutes, and knowing what to do in the first sixty seconds of a burst can be the difference between a mop-up and a renovation.

Why Pipes Burst When They Freeze

Water expands as it freezes. When water inside a pipe turns to ice, it pushes outward with enormous force — and here’s the part most people get wrong: the pipe usually doesn’t split where the ice is. The expanding ice builds pressure downstream of the blockage, between the ice and a closed faucet, and the pipe bursts at that weak point. That’s why letting a faucet drip helps: it relieves the pressure that actually does the damage.

The pipes most at risk are the ones with the least protection — exterior hose bibs, pipes in unheated crawl spaces and garages, and any plumbing running along an outside wall.

How to Prevent Frozen Pipes (Before the Freeze)

Do these once at the start of winter, and again before any hard freeze in the forecast:

• Disconnect and drain garden hoses, and shut off the interior valve to outdoor spigots if you have one. A connected hose traps water in the bib and is a top cause of burst outdoor pipes.
• Insulate exposed pipes in crawl spaces, garages, and the attic with foam pipe sleeves — a few dollars per length at any hardware store.
• Seal drafts near pipes — gaps where lines enter the house let freezing air right onto the pipe.
• Know where your main shut-off is (and that it works) before you ever need it.

What to Do During a Hard Freeze

When the forecast drops below freezing for several hours, especially overnight:

• Let faucets drip — a slow trickle on the fixtures farthest from where your water enters keeps water moving and relieves pressure. This is the single most effective overnight move.
• Open cabinet doors under sinks on exterior walls so household heat reaches the pipes.
• Keep the heat on — don’t drop the thermostat below 55°F at night, even if you’re away.
• Open the garage door’s weather seal area — if there’s plumbing in the garage, keep that door closed and the space as warm as possible.

If a Pipe Is Already Frozen (But Not Burst)

If you turn on a tap and only a trickle comes out, a pipe is likely frozen. Act before it bursts:

1. Open the faucet so water can flow once it thaws and pressure can escape.
2. Apply gentle heat to the frozen section — a hair dryer, a space heater kept at a safe distance, or towels soaked in hot water. Work from the faucet end toward the blockage.
3. Never use an open flame — no torches, no propane heaters aimed at the pipe. That’s how house fires start.
4. If you can’t reach it or it won’t thaw, call us — a frozen pipe in a wall or crawl space is hard to reach safely.

If a Pipe Bursts — Do This First

This is the emergency. Move fast:

1. Shut off the main water supply immediately. This is why knowing your shut-off location ahead of time matters — every minute is gallons.
2. Turn off the water heater if the burst affects hot-water lines, so it doesn’t run dry.
3. Open faucets to drain the remaining water in the system and relieve pressure.
4. Move valuables and soak up water to limit damage.
5. Call for emergency service. A burst pipe is exactly the situation our 24/7 line exists for — see when to call an emergency plumber.

The faster the water is off, the smaller the repair and the cleanup.

What Repairs Cost

Water damage cleanup is separate and often dwarfs the plumbing repair — which is exactly why prevention and a fast shut-off pay for themselves.

Frequently Asked Questions

At what temperature do pipes freeze? Generally around 20°F or below, especially if sustained for several hours overnight. Exposed and uninsulated pipes freeze first, which is why a 25°F night can still burst a crawl-space pipe.

Does letting a faucet drip really prevent freezing? Yes — it keeps water moving and, more importantly, relieves the pressure that builds between an ice blockage and a closed faucet. That pressure is what actually bursts pipes.

My pipes froze but didn’t burst. Am I in the clear? Once thawed and flowing normally, yes — but it’s a warning. That pipe will freeze again next cold snap. Insulate it before the next freeze.

Should I shut off my water if I leave town in winter? For an extended absence, yes — shut off the main and drain the lines, or at minimum keep the heat at 55°F+ and have someone check the house. A burst pipe in an empty home can run for days.
