Northwest Arkansas winters catch a lot of homeowners off guard. The region does not get the prolonged deep freezes of northern states, but it gets something in some ways more dangerous: rapid temperature swings. A week in the 50s followed by an overnight drop to the single digits creates conditions that burst pipes in homes that would survive a Minnesota winter without a problem, because those homes are built for it and these are not.
Pipe freezes and bursts are one of the most common plumbing emergencies NWA C&S Plumbing responds to each winter in Springdale, Fayetteville, Bentonville, and Rogers. The calls almost always come from homeowners who either did not know the risk or assumed it would not get cold enough to matter.
This guide covers what you need to do before winter arrives, what to watch for during cold snaps, and what to do immediately if you suspect a pipe has already frozen.
Why Pipes Freeze and Burst in Arkansas Homes
Water expands when it freezes. When water inside a pipe freezes, the expansion creates pressure that the pipe cannot absorb. The pipe does not always burst at the ice blockage itself. The pressure buildup between the blockage and a closed fixture is what causes the failure, and that failure can happen several feet away from where the ice formed.
Arkansas homes are particularly vulnerable because they are built for a moderate climate. Pipes in exterior walls often have little or no insulation behind them. Crawl spaces beneath homes are frequently uninsulated and open to outside air. Pipes running through garages, outbuildings, and unheated spaces have no protection at all.
A single night below 20 degrees Fahrenheit is enough to freeze an exposed pipe in an Arkansas home if there is no airflow from the interior heating system reaching that area.
Step One: Know Where Your Main Water Shutoff is
Before winter arrives, and before any emergency happens, locate the main water shutoff valve for your home. If a pipe bursts, turning off the water immediately limits the damage. Every minute the water runs is more damage to floors, walls, ceilings, and belongings.
The main shutoff is typically located where the water line enters the home. In crawl space homes this is often near the foundation. In slab homes it may be in a utility closet, garage, or near the water meter at the street.
Make sure every adult in the household knows where it is and can operate it. A shutoff valve that has not been used in years may be stiff. Test it now so you know it works.
Step Two: Insulate Exposed Pipes
Pipe insulation is inexpensive and available at any hardware store. Foam pipe sleeves slip over exposed pipes and provide a buffer against cold air. This is the single most effective step for preventing frozen pipes in locations that get cold but where the pipe is accessible.
Focus on pipes in these locations: crawl spaces, garages, unheated utility rooms, exterior walls where the pipe is accessible from a cabinet or access panel, and any pipe running through a space that does not share heating with the main living area.
In a finished home where pipes are inside walls, insulation is not accessible. But in crawl spaces and garages, a few dollars of foam sleeve can prevent a very expensive burst.
Step Three: Disconnect and Drain Outdoor Hoses
A garden hose left connected to an outdoor spigot traps water in the spigot body and the pipe behind it. When that water freezes, it can split the spigot and damage the pipe behind the wall.
Disconnect all garden hoses before the first hard freeze and drain them before storing. If your home has frost-free spigots, they are designed to drain when the hose is disconnected. A hose left connected defeats that feature.
If you have an older spigot that is not frost-free, an insulated spigot cover provides additional protection during cold nights.
Step Four: Keep Heat on During Cold Snaps
This is the step homeowners most often underestimate. During extended cold periods, the interior temperature of the home matters for the pipes inside the walls and beneath the floors, not just for comfort.
Do not turn the thermostat below 55 degrees Fahrenheit during a freeze, even in an unoccupied home. Leaving for a few days during a cold stretch and dropping the heat to save money is a reliable way to come home to a burst pipe.
If your home has cabinet doors under sinks on exterior walls, opening those doors during cold nights lets warm interior air circulate around the pipes beneath. This simple step prevents freezes in vulnerable locations.
Step Five: Let Faucets Drip During Severe Cold
When overnight temperatures are expected to fall into the single digits or stay below 20 degrees Fahrenheit for extended periods, letting the most vulnerable faucets drip slightly reduces the risk of freeze.
Moving water is harder to freeze than standing water. Even a slow drip maintains flow in the line, which helps prevent ice from forming. Focus on faucets connected to pipes running through exterior walls or unheated spaces.
This is not necessary for every cold night in Northwest Arkansas, but it is a reasonable precaution during the two or three genuinely severe cold events the region typically experiences each winter.
Crawl Space Homes Have Added Risk
A significant portion of Northwest Arkansas homes, particularly older properties in Fayetteville and Springdale, sit on crawl spaces. The pipes beneath these homes are exposed to outside temperatures when outside air can circulate freely through crawl space vents.
Some older homes were built with crawl space vents that were intended to prevent moisture buildup but allow cold air to reach pipes directly. Closing these vents during winter and sealing any gaps in the crawl space foundation reduces cold air circulation significantly.
Adding insulation to the crawl space ceiling, which is the floor of the living area above, helps as well. This is a more involved project but meaningful for homes that have experienced repeated freeze problems.
What to Do If a Pipe Freezes
If you turn on a faucet during a cold stretch and nothing comes out, or only a trickle, a pipe has likely frozen. Do not panic and do not try to thaw it with an open flame.
Turn off the main water shutoff first. If the pipe has already burst but the ice blockage is still in place, you may not see water immediately. When the ice thaws, the burst section will begin to flow. Having the water off when that happens limits the damage significantly.
Apply gentle warmth to the suspected area using a hair dryer, a heating pad, or warm towels. Work from the faucet end toward the cold section. Do not use a torch, heat gun at full power, or any open flame near pipes.
Call a licensed plumber to assess the pipe before restoring water service. If the pipe has already cracked or split, turning the water back on without knowing the pipe’s condition leads to a significant water event inside your home.

Frequently Asked Questions
At what temperature do pipes freeze in Arkansas homes?
Exposed pipes in uninsulated spaces can freeze at sustained temperatures below 20 degrees Fahrenheit. Pipes inside exterior walls with poor insulation can freeze at temperatures in the low 20s, depending on wind chill and how long the cold persists.
How long does it take a pipe to freeze?
Pipes in uninsulated spaces can freeze in as little as 6 hours during severe cold. Pipes inside walls take longer but can freeze overnight in single-digit temperatures.
Does homeowners insurance cover burst pipes in Arkansas?
Most standard homeowners insurance policies cover sudden and accidental pipe bursts, including water damage. Damage from pipes that were not maintained or that froze due to negligence, such as leaving heat off in a vacant home, may not be covered. Review your policy and document any winterization steps you take.
Should I shut off my water when I leave for the holidays?
Shutting off the water and draining the lines is the most protective step during extended absences in winter. If someone is checking the home, keeping the heat at 55 degrees or above and leaving cabinet doors open under sinks is an alternative.
Are there pipes I cannot insulate because they are inside walls?
Yes. Pipes inside finished walls are not accessible for direct insulation. The best protection for those pipes is maintaining interior heat and, in very vulnerable areas, a slow drip from the connected faucet during severe cold.
Conclusion
Preparing your plumbing for an Arkansas winter takes less than an afternoon and costs far less than the average burst pipe repair. Know your shutoff location, insulate what you can reach, disconnect outdoor hoses, and keep the heat on during cold snaps.
