Freezing Nights in Acworth: How to Stop Attic, Crawl Space & Lake-Home Pipe Bursts

Georgia winters are mild most of the time, which is exactly why frozen pipes catch Acworth homeowners off guard. Homes here aren't built for long hard freezes, so a few nights in the teens or low 20s can split pipes in attics, crawl spaces and exterior walls. Here's where pipes freeze in Acworth homes, what to do before a cold snap and what to do if one bursts.

At what temperature do pipes freeze in Georgia homes?

Pipes in unheated attics, crawl spaces and exterior walls are at risk when outdoor temperatures drop into the low 20s or below, especially overnight and in wind.

There's no single number, because it depends on where the pipe runs and how long the cold lasts. A pipe in a heated wall may never freeze, while one in a vented crawl space or an attic above a bathroom can freeze after one hard night. Wind makes it worse by pulling cold air through vents and gaps.

Where pipes freeze in Acworth homes

Before the cold snap: your checklist

• Disconnect garden hoses and cover outdoor faucets.
• Insulate exposed pipes in the attic, crawl space and garage with foam sleeves.
• Seal gaps where cold air reaches pipes, like around crawl space vents and rim joists.
• Close foundation vents during hard freezes if your home has them.
• Keep the thermostat steady day and night, even if you're away.
• Open cabinet doors under sinks on exterior walls.
• Let faucets drip on the coldest nights, both hot and cold on exterior-wall fixtures.
• Know your main shut-off valve and make sure it turns.

Vacant homes and lake houses

Second homes near Lake Allatoona and houses left empty over the holidays are where the worst burst-pipe damage happens, because water can run for days. If a home will sit empty in winter:

• Keep the heat on at a steady setting
• Or shut off the main water and drain the lines
• Have the system winterized for long vacancies
• Install leak sensors with phone alerts
• Ask someone to check the house after hard freezes

When bringing a winterized home back into use, do it carefully. Cobb County Water System notes that if a home isn't properly de-winterized, restoring water can cause leaking pipes.

Signs a pipe is frozen

• Little or no water from a faucet when it's freezing outside
• Frost on visible pipes
• Strange smells from drains
• Bulging or cracked pipe sections

If a pipe is frozen but not broken, open the faucet and warm the pipe gently with a hair dryer or space heater kept at a safe distance. Never use an open flame. If you can't find the frozen section or it's in a wall or ceiling, call a plumber.

If a pipe bursts

• Shut off the main water valve right away.
• Turn off power to wet rooms if it's safe.
• Open faucets to drain remaining water from the lines.
• Move belongings and photograph the damage.
• Call a plumber for the pipe and a water damage crew for the cleanup.

Burst pipes in attics bring water down through ceilings, insulation and light fixtures, so the attic and ceilings need to be checked, not just the floors. See burst pipe water damage cleanup in Acworth

Don't forget the water bill

If a burst pipe on your side of the meter ran up your bill, Cobb County Water System may offer a partial leak credit once in a rolling 12-month period with a repair receipt. Keep every receipt. See Cobb County water leak credit guide
