When the temperature drops, either suddenly or slowly over a matter of weeks, it can be very easy to overlook the biggest leak danger of your house: Frozen pipes.

This is more likely to happen on water lines indoors that are set on external walls, in hallways or rooms without radiators and vents, or if they’re running externally around your property. If the water in the pipe freezes, it will expand, causing damage and leaks.

Why Electric Heating Cables for Frozen Pipes are So Effective

Joseph Wade, VP of Operations at Benjamin Franklin Plumbing, says, ‘If you have outdoor pipes that will be exposed to these freezing temperatures and you know you won’t have to use them all winter, shut off the water supply in them and drain. Disconnect hoses from the pipes and leave the outside valve open in case there’s water left in the lines.

‘For those lines you can’t shut off, you’ll have to insulate them. Check out your local hardware store and invest in pipe sleeves, heat tape or heat cables [jump to our picks for home delivery]. These items will be your best option for insulating pipes that run outside your house or in unheated areas like an attic or basement. Newspapers might work if temperatures don’t drop far below freezing, but specific products like pipe sleeves, heat tape, and heat cable are more reliable.’

Walmart Shoppers rave about the Frost King cable, which is 12-feet long, and has an average rating of 4.8/5. One verified purchaser left a five-star review, explaining, ‘It was exactly what I needed. We have been having long extended periods of temperatures between 20° and 0° so the drain for the water from the furnace has been freezing.

'Heating up the garage was not enough to keep it from freezing over. I put this on the drain pipe, and it hasn't frozen since. It isn't much heat, but just enough. I have been using it for a few weeks now, and it seems to be working just great even with the snow and wind.’

You can use the kit on plastic or metal cold water lines, and it accommodates two-inch pipes well, offering excellent pipe freezing prevention down to -40° Fahrenheit. This is an essential move for adequately winterizing your home, and time and money well spent.

If your pipe has already frozen, the product will help gently thaw it at a rate that won’t lead to leaks or further problems, as defrosting too rapidly can cause bursts .

Walmart's Frost King kit also has built-in self-regulation mechanisms, meaning it will draw power and start doing its magic to stop pipes from freezing automatically. It will activate at 38°F and deactivate at 45°F. This will ensure it doesn’t run up bills unnecessarily, which, with energy costs being what they are in 2025, every little saving to slash your bills in the winter is worth knowing about.

You don’t have to do any guesswork for the operation either, as there is a light that switches on (it’s located in the plug), which will tell you whether it’s on or not.

Pro Pipe Tips in Winter

Here are some extra tips from plumbing pro Joseph, to help you prevent and deal with pipes that have frozen up.

  • Value location: Be sure you know where the main water shutoff valve is in your house. If, despite your best efforts, a pipe freezes and bursts, turn off the water immediately to limit the damage, then work on thawing the affected pipes.
  • Install sensors and automatic shut-off valves: Today, you have the option of installing sensors that detect water, and in some cases, temperature change. If the sensors detect a problem, it will notify you through the app and shut off the water to prevent water damage. Amazon sells a three-pack of sensors for water leaks affordably, and they come with app functionality, which shoppers praise for its 'seamless' and easy setup.
  • Don’t turn off the heat: When you leave your house during winter, don’t turn off the thermostat – that’s a heating mistake to avoid. That drop in temperature inside the home can lead to frozen pipes. Make sure to also check out your water shut-off valve is working correctly in case of an emergency where you have to shut off the water supply to your home.

If you haven’t been able to prevent a frozen pipe this winter:

  • Warm it up slowly: Once you’ve identified a problematic pipe, gently warm the air around the frozen section using a space heater (be careful to check manufacturer information on yours, as they are not all suitable for outdoor use), a warm towel, or a heat lamp. Do not turn to flames or torches, or hairdryers on high heat settings, as that can warm the pipe up too quickly and lead to other issues.
  • Run the faucet: Experts also recommend that you turn the faucet on so that you allow water to flow as the ice melts away. Frozen pipes are not to be taken lightly, and if you’re in any doubt about how to deal with yours, call the pros.

Plumbing pro Joseph adds that if the troublesome pipe is in your ceiling, he recommends homeowners call a licensed plumber. He says, ‘This is difficult to thaw yourself. Most times, the wall or ceiling will have to be cut to access the frozen pipe.’

What to Shop


If you've been battling a frozen or snowy driveway, ditch the expensive salt, which can damage your lawn and plants, and instead use sand to add instant grip and traction to walk and drive on the surface without backbreaking shovelling.

Once it has melted away, scoop up the sand and save it in a lidded bucket for reuse later. It's a great way to be more sustainable at home whilst coping with preparing your home for a freeze.
