Quick answer: for most Texas homes, an insulated cover on every outdoor faucet and rubber or foam insulation on exposed lines (attic first) handle an ordinary freeze. Add a thermostat-controlled heat cable only on a pipe that has frozen before or that sits somewhere you can’t keep above freezing.
Texas doesn’t get many hard freezes, which is exactly why so many homes weren’t ready in February 2021. The Department of State Health Services confirmed 246 deaths tied to that storm [1]. Waco’s airport sat at or below freezing for 205 straight hours, a record, and DFW fell to -2°F on February 16 [2]. Pipes that had never needed protection burst across the state.
At a glance
How we chose
- Follows Texas advice. The Texas Department of Insurance’s freeze checklist is insulate attic pipes, cover outdoor faucets and know where your water shutoff is [3]. We picked products for each step.
- Heat cable must self-regulate. We only list cables with a built-in thermostat, so they switch on near freezing instead of running all winter. Plug each into a ground-fault (GFCI) protected outlet [4].
- Maker specs only. Sizes and ratings come from the manufacturer’s own pages. Where a maker doesn’t publish a number, such as an R-value, we don’t guess one.
- Sold on Amazon. Every pick links straight to its own Amazon listing. Some cables and insulation come in many lengths or sizes, so check that the listing matches your pipe.
- Recall check. We searched the CPSC recall database for each brand and model on November 7, 2026 [8].
Our picks
Best for: Every outdoor hose bib
Duck Brand Flexible Faucet Cover (7.5 x 8.75 in., black)
The cheapest fix on this page and the one TDI points to first: outdoor faucets should be insulated, not dripped. This soft cover slides over the spout and pulls snug, with no adhesive, so renters can use it too.
- 7.5 x 8.75 in. soft cover [6]
- Slides over the spout and pulls tight; no adhesive [6]
Safety check: No certification applies to a passive cover. No CPSC recall found for Duck brand or its maker, Shurtape, or for faucet covers (checked 2026-11-07).
Watch out: Duck doesn't publish an R-value or the insulating material. Disconnect the hose first, and check that the cover fits your faucet's size.

Best for: Tight bends and crowded spaces
Frost King RS511XB/6 Rubber Tubular Pipe Insulation
Rubber is more flexible than polyethylene foam, so it's easier to fit around elbows and in cramped attics. It is pre-slit and self-sealing, so there's less taping.
- Rubber, pre-slit, self-sealing [5]
- 1/2-inch wall, 6-foot length [5]
- Fits 3/4-inch inside diameter [5]
Safety check: No CPSC recall found for Frost King rubber insulation (checked 2026-11-02).
Watch out: Costs more per foot than polyethylene foam. Measure your pipe first: Frost King lists more than a dozen sizes.

Best for: A pipe that has frozen before
Frost King HC Automatic Electric Heat Cable Kit (HC3A to HC30A)
Built-in thermostat turns the cable on below 38°F and off above 45°F, so it only draws power in cold weather. Sold in fixed lengths from 3 to 30 feet; pick the one that matches your pipe.
- 120V, 7 watts per foot [4]
- Thermostat on below 38°F, off above 45°F [4]
- Copper, iron or Schedule 40 plastic water pipe only [4]
- Light on the plug shows power [4]
Safety check: No CPSC recall found for Frost King or Thermwell heat cables (checked 2026-11-02).
Watch out: Not for PVC, hoses or mobile-home feed lines, and never inside walls, floors or ceilings. Never overlap it or use a cable longer than the pipe. Frost King calls for fiberglass insulation with a vapor seal over it, not foam.

Best for: Longer runs in crawl spaces and pier-and-beam homes
Wrap-On Pipe Heating Cable, 30 ft (31030)
A low-wattage cable with a built-in thermostat that switches on at 38°F, in lengths from 3 to 100 feet. Wrap-On sells each length separately; this link is the 30-foot model, so match the length to your pipe.
- 2 watts per foot; 31030 is 60 W, 0.50 A at 120V [7]
- Built-in thermostat turns on at 38°F; protects to -50°F, per the maker [7]
- Metal and rigid plastic water-filled pipe [7]
- Lengths from 3 to 100 ft. [7]
Safety check: No CPSC recall found for Wrap-On heating cables (checked 2026-11-07).
Watch out: Not for fuel lines, drain lines, hoses or buried pipe. Wrap-On calls for fiberglass pipe wrap over the cable to finish the job. Its page doesn't state a GFCI requirement, but plug it into a GFCI-protected outlet as the CPSC's heat-tape advice suggests.

Buying guide
- Start in the attic. That’s where Texas pipes froze most [3]. Measure each pipe’s outside diameter and buy insulation sized to it.
- Cover every outdoor faucet. Disconnect the hose first. No cover? TDI says a towel and tape will do in a pinch [3].
- Heat cable is for problem pipes, not every pipe. Buy a length that matches the pipe (never longer), and plan for a GFCI outlet nearby [4]. Both cables here call for fiberglass insulation over them [4][7].
- Find your main shutoff now. TDI says it’s usually near the street in a concrete or plastic box. If a pipe bursts, or you can’t insulate, shutting off and draining the lines is the backup plan [3].

Common questions
Should I drip my outdoor faucets during a Texas freeze?
No. The Texas Department of Insurance says not to drip outside faucets but to insulate them, with a faucet cover or a towel and tape. Dripping indoor hot and cold taps is the step it suggests for indoor lines, if your city isn't limiting water use.
Where do Texas pipes freeze most often?
In the attic. The Texas Department of Insurance says the attic was the number one place pipes froze in the winter after the February 2021 storm, so insulating attic lines is the first job.
Is heat tape safe?
It can be if you follow the maker's instructions. The CPSC has long linked heat tapes and cables to house fires and says to inspect them every fall and replace any with cracked covering, bare wire or charring. Plug the cables on this page into a GFCI-protected outlet, and never let them overlap themselves.
