Texas Freeze Survival Guide

Texas homes are built for heat, not cold, which is exactly why a hard freeze does disproportionate damage here compared to a similar cold snap in a traditionally cold-winter state. This is a deep dive specifically on preparing for a Texas hard freeze: why the state's home construction makes pipes so vulnerable, the difference between a statewide grid emergency and a local ice-related outage, and the specific prep that matters most. For our broader Texas multi-hazard kit covering tornadoes, heat, and hurricanes, see the Texas Emergency Kit guide.

Why Texas Homes Are Uniquely Vulnerable

During Winter Storm Uri in February 2021, more than 17 million Texans lost access to safe tap water as pipes froze and burst statewide, with temperatures staying below freezing for roughly 8 to 10 consecutive days and insured losses estimated around $8 billion. The scale of that damage traces back to an architectural reality: most Texas homes are built for a hot, humid climate where hard freezes are historically rare, so water pipes routinely run through uninsulated attics, exterior walls, garages, and crawlspaces with little or no thermal protection. In a traditionally cold-winter state, those same pipes would typically run through conditioned, insulated interior space specifically because hard freezes are expected. In Texas, a freeze that would be unremarkable in Minnesota or Michigan can be genuinely catastrophic, because the housing stock itself wasn't designed for it.

ERCOT Grid Emergencies vs. Local Ice-Related Outages

Not every winter power problem in Texas is the same kind of event, and knowing which one you're facing changes what you should do:

• An ERCOT conservation alert or grid emergency means the statewide grid operator is asking Texans to reduce electricity use because generation capacity is strained, often specifically because cold weather is affecting power plants and gas supply simultaneously, the failure mode behind the 2021 blackouts. This can mean planned, rotating outages across the state, potentially for days, regardless of whether your specific neighborhood has any local storm damage at all.
• A local ice-related outage is a normal-for-winter-weather event: ice accumulation on lines and trees causing outages in your specific area, similar to what happens in any ice-prone region, typically resolved by local utility repair crews rather than a statewide capacity shortfall.
• Why the distinction matters: A local outage is usually a matter of "how long until the repair truck gets to my street." A statewide ERCOT emergency is a matter of "how long until the grid itself can carry normal load again," which can be a very different and less predictable timeline, and rotating outages during one may hit areas with zero physical storm damage at all.

Follow both your local utility's outage map and ERCOT's public conservation alerts during a winter event, since they tell you different things: one about your street, one about the whole grid.

Protecting Texas Pipes Specifically

Because Texas plumbing so often runs through unconditioned space, focus your prevention effort on the specific locations most Texas homes actually route pipes through:

• Attic pipes: common in Texas construction; insulate exposed lines and consider heat tape on any run in an unconditioned attic. See our heat tape guide
• Exterior wall cavities: open cabinet doors under sinks on exterior walls during a hard freeze to let interior air reach the pipes
• Garages: many Texas homes route water heater or laundry lines through an attached, unconditioned garage; keep the garage door closed and consider insulating those runs specifically
• Outdoor spigots and hose bibs: disconnect hoses and cover every exterior faucet; see our faucet cover guide
• Know your main shutoff before you need it: if a pipe does burst, shutting off the main immediately limits the damage far more than any amount of towel-mopping afterward. See our frozen pipes: what to do guide

Texas Freeze Checklist

• Insulate or heat-tape exposed attic, garage, and exterior-wall pipe runs
• Disconnect hoses and cover all outdoor spigots
• Know your main water shutoff location before a freeze, not during one
• Let vulnerable faucets drip during a hard freeze
• Open cabinet doors under exterior-wall sinks
• Charge power stations and phones before the storm arrives
• Stock 7+ days of water and non-perishable food
• Have a non-grid-dependent heating plan (see our winter power outage guide)
• Stock sleeping bags and thermal curtains for indoor cold if heat fails
• Follow both your local utility's outage map and ERCOT conservation alerts
• Withdraw cash: card readers and ATMs may be down along with the power
