As the UK shivers under a blanket of snow and ice, homeowners are being urged to avoid a common but costly mistake when dealing with frozen pipes. Experts warn that a well-intentioned quick fix could lead to repair bills running into thousands of pounds.
The High Cost of a Hasty Thaw
New data from the UK insurance industry reveals the stark financial impact of water damage from burst pipes. The average escape-of-water claim now stands at around £2,700. In more severe cases, where damaged flooring, plasterwork and electrical systems need replacing, the final bill can escalate far beyond this figure.
Tony Reynolds, a home maintenance specialist at building supplies retailer Supreme Merchants, states that many of these expensive claims originate from incorrect attempts to defrost pipes. In a bid to solve the problem quickly, people often resort to methods that do more harm than good.
What NOT to Do With Frozen Pipes
Reynolds has issued a clear warning against two particularly dangerous tactics: using boiling water or a blowtorch or naked flame on a frozen pipe. "Boiling water and naked flames crack pipes every year," he explained. "People do not realise that the pipe itself is still freezing cold inside, even if the outside feels warm."
The extreme and localised heat from these methods causes the pipe to expand too rapidly. Because the ice blockage remains inside, the pressure has nowhere to go, leading to cracks or split joints. This turns a simple thawing job into a major plumbing emergency.
The Safe, Expert-Recommended Method
Instead of reaching for the kettle or blowtorch, Reynolds advocates for a gentler, more gradual approach using an item many households already own. "Electric blankets and heated throws are brilliant for frozen pipes," he said.
He explains their suitability: "They are built for long, low-level heat, which is exactly what you want when ice is blocking a pipe." This consistent, mild warmth slowly melts the ice from the outside in, allowing the water to flow again without subjecting the pipe to thermal shock.
"People think they are saving time, but one split joint can turn into weeks of repairs," Reynolds cautioned. "Using gentle heat from something like an electric blanket could genuinely save households thousands."
The Crucial Extra Step Most People Miss
If you are using an electric blanket to defrost a pipe, Tony Reynolds shares one vital professional tip that is frequently overlooked. Before you even switch the blanket on, you should slightly open the tap fed by the frozen pipe.
He clarifies why this simple action is so important: "That tiny flow relieves pressure as the ice melts. It is one of those tricks experts know, but homeowners rarely do." Allowing water to drip out as the ice thaws prevents a dangerous build-up of pressure inside the pipe, further reducing the risk of a burst.
With the cold snap set to continue, taking a patient, informed approach to frozen pipes can be the difference between a minor inconvenience and a devastating and expensive home disaster.
