What to Do When Your Pipes Freeze This Winter in Worthing

Published October 2026 | Frozen Pipes

Your heating's been off overnight, temperatures dropped below zero, and now the kitchen tap is running dry. Or maybe there's a thin trickle where there should be a full flow. You're fairly sure you've got a frozen pipe - but do you try to sort it yourself, or do you call a plumber?

It's a more common winter situation than most Worthing homeowners expect, and the decision you make in the next hour or two can be the difference between a minor inconvenience and a flooded kitchen. There are two realistic paths here: attempt to thaw the pipe yourself, or call a professional. Both can be the right call depending on what you're actually dealing with.

Option A: Thawing Your Frozen Pipes Yourself

DIY thawing means applying gentle heat to a frozen section of pipe yourself, using items you likely already have at home. It's the first instinct for most people, and in certain situations it's a reasonable approach that costs you nothing and gets water flowing again quickly.

How DIY Pipe Thawing Works

The principle is simple: apply controlled heat to the frozen pipe to melt the ice blockage and restore flow. Here's how it's typically done:

1. Locate the frozen section - usually an exposed pipe in an unheated space such as the loft, garage, under the kitchen sink, or inside an external wall cavity.
2. Open the nearest tap so water can drain freely as the ice melts.
3. Apply gentle heat using a hairdryer on a low or medium setting, warm towels soaked in hot water, or a hot water bottle wrapped around the pipe.
4. Work from the tap end backwards towards the frozen section, not from the frozen point inward. This lets melting water escape rather than building pressure behind the blockage.
5. Check the tap periodically - when water starts flowing again, the blockage has cleared.

Never use a naked flame, a blowtorch, or a heat gun. These can cause water inside the pipe to turn to steam faster than it can escape, which risks rupturing the pipe or starting a fire. And never use electric heat sources near standing water if there's any sign the pipe may already have split.

What DIY Thawing Costs

If you already have a hairdryer at home, the cost is essentially nothing. A few extra towels or a hot water bottle adds a few pounds at most. That's the main attraction - it's immediate and costs almost nothing to attempt.

Pros of the DIY Approach

• No call-out fee.
• You can start immediately, at any hour.
• For a simple, accessible pipe, it often works.
• You identify which pipes in your home are most vulnerable.

Cons of the DIY Approach

• If the pipe has already cracked, thawing it will cause it to flood.
• You may not be able to find or access the frozen section at all.
• Applying heat incorrectly can damage plastic or older lead pipework.
• A hairline crack you can't see won't reveal itself until the ice melts and water starts pushing through.

As Watersafe.org.uk notes, frozen pipes left unchecked can lead to burst pipes and costly water damage - and acting quickly is what limits the fallout. DIY thawing works best when you can see the pipe, reach it easily, and you're confident it hasn't already split. The moment pipes are inside walls, under floorboards, or in the loft - or if there's any hint of water damage nearby - the DIY route becomes a much riskier bet.

Option B: Calling a Professional Plumber in Worthing

Calling out a qualified plumber means handing the problem over to someone with the tools, training, and experience to diagnose what's actually happening across your whole system - not just treating the obvious symptom in front of them.

What a Plumber Will Do

A professional plumber won't just warm up the frozen section and head off. They'll approach it systematically:

1. Locate the frozen or burst section, using thermal imaging equipment in more complex cases.
2. Isolate the water supply before applying any heat, if there's any sign of cracking or splitting.
3. Safely thaw the pipe using specialist equipment designed for the job.
4. Inspect the full pipe run for stress damage or micro-cracks that wouldn't be visible to you.
5. Carry out any necessary repairs, replacing damaged sections where needed.
6. Advise you on which pipes in your property are most at risk in future cold spells, and what lagging or protection is worth fitting.

This is the version of events where you end up with a properly assessed system, not just a reopened tap and fingers crossed that nothing else is wrong.

What Professional Call-Out Costs in West Sussex

Emergency plumber call-out rates across West Sussex typically range from 80 to 150 pounds just to attend, before any work is carried out. Hourly labour rates commonly run between 60 and 100 pounds depending on the firm and whether it's out of hours. If the pipe has burst and needs a section replacing, total costs typically sit between 200 and 500 pounds for most standard jobs. Where water has got into flooring, wall cavities, or ceilings, costs can push considerably higher. In almost every case, acting early works out cheaper than managing the aftermath of a burst.

Pros of Calling a Professional

• Full diagnosis, not just a surface fix.
• Proper equipment for thawing without causing further damage.
• If there's a split, they can repair it before the flooding starts.
• Work comes with professional guarantees and accountability.
• Practical advice on lagging and prevention going forward.

Cons of Calling a Professional

• Higher upfront cost than attempting it yourself.
• In a genuine emergency, particularly overnight, you may be waiting for an available engineer.
• Call-out rates at weekends and in the early hours are typically higher than standard daytime rates.

Side-by-Side Comparison

The comparison makes one thing clear: DIY works in a fairly narrow set of circumstances. The moment anything is uncertain - where exactly the freeze is, whether the pipe has split, whether you can access it safely - a professional is the lower-risk option even if the upfront cost is higher.

Which Is Right for Your Situation

There's no single answer that fits every home and every frozen pipe, but there are some clear decision points worth working through.

Go DIY if:

• The frozen section is visible and accessible - under the kitchen sink, in the garage, on an exposed section of external pipework.
• There's no sign of water leaking or damp patches anywhere near the affected pipe run.
• You can reach the pipe safely without needing to climb into a loft or move heavy fixtures.
• Temperatures only just dipped below zero overnight, suggesting the freeze is likely shallow.

Call a professional plumber if:

• You can't locate the frozen section and you're guessing based on which taps aren't working.
• There's any dampness, bubbling paint, discolouration on ceilings, or dripping near the affected area - these suggest the pipe may already be cracked.
• The pipe runs through a wall, under a floor, or in the loft.
• You've applied heat for 20-30 minutes and water still isn't flowing.
• Temperatures have been severely below zero for several consecutive days, significantly increasing the risk of pipe damage.
• You're not certain where your main stopcock is or can't turn it off reliably.

If you're not sure whether you're dealing with a frozen pipe or another plumbing fault altogether, the Voltrade GoFIX diagnostic tool can help you identify the likely issue before you decide your next step - useful for ruling out other problems before you start applying heat in the wrong place.

What Worthing Homeowners Typically Choose and Why

In our engineers' experience working with homeowners across Worthing and the wider West Sussex area, the split tends to break down along two lines: where the pipe is located, and how confident the homeowner is in what they're actually dealing with.

Many people living in Worthing's older housing stock - Victorian and Edwardian terraced houses particularly - have pipework that runs through uninsulated external walls or exposed loft spaces. These properties tend to freeze first and hardest when temperatures drop, because those pipe runs were never built with modern insulation standards in mind. In those homes, professional help is much more commonly the right route, simply because the freeze is rarely in a location you can get at yourself.

Homeowners in newer builds, particularly those constructed from the 1980s onwards, often have more accessible pipework and better-insulated systems. In those properties, DIY thawing of an under-sink or garage pipe is more workable - provided there are no warning signs of damage.

As local plumbing engineers in Worthing note, pipes can freeze and expand suddenly when temperatures shift, which is exactly why a pipe that appears fine after DIY thawing may still carry hidden structural damage. Our engineers also see this regularly across Worthing: homeowners who applied some heat, assumed the problem was resolved, and then found a week later that a hairline crack had been weeping slowly into a wall cavity or behind a kitchen unit. The water damage from that scenario is typically far more expensive to remedy than the original call-out would have been.

The pattern our engineers consistently observe is this: homeowners who call a professional early tend to spend less overall, because problems are caught before they escalate. Those who manage it themselves for a day or two before calling tend to have more extensive damage to deal with by the time an engineer arrives.

Making Your Decision

If you're still weighing it up, these four questions should bring you to a clear answer.

Can you actually see and reach the frozen pipe?

If you can put your hand directly on the pipe and apply heat to it without needing to move anything significant, that's a genuine DIY candidate. If you're estimating where the freeze might be based on which taps aren't working, or you know it's inside a wall, under a floor, or in the loft, you need a professional. Accurate diagnosis alone is worth the call-out cost, because working on the wrong section wastes time and doesn't solve anything.

Is there any sign of water damage near the pipe or on adjacent walls?

Bubbling or flaking paint, damp patches, discolouration on ceilings or walls, or any dripping near the affected area - even very slow dripping - means the pipe may already be compromised. If you thaw a cracked pipe without first isolating the water supply, you'll turn a frozen pipe problem into a flooding emergency. A professional plumber will isolate and assess before applying any heat whatsoever.

How long has the freeze been in place?

A pipe that froze during a single cold night is in a very different situation to one that's been solid for several days. The longer a freeze persists, the more ice can expand and stress the pipe material. Extended freezes are particularly damaging to older copper or lead pipework - common in parts of Worthing's older housing stock - where the material may already be weakened. The longer the freeze, the stronger the case for bringing in a professional before you attempt anything.

Do you know exactly where your main stopcock is and can you turn it off quickly?

Before attempting any DIY thawing, you need to know precisely where your main stopcock is and be confident you can reach it in seconds. If a pipe splits the moment the ice starts to melt, you have very little time to get the water off before serious damage begins. The stopcock is typically under the kitchen sink or where the supply enters the property. If you're not sure where yours is, find it now. If it's stiff or difficult to operate, get that sorted before you touch any frozen pipe - or call a plumber from the outset.

Frequently Asked Questions

How do I know if I have a frozen pipe rather than another plumbing problem?

The clearest sign is a combination of very cold overnight temperatures and reduced or absent flow from one or more taps, while others work normally. Frozen pipes typically affect specific sections of a property - taps furthest from the boiler, or those on external walls, tend to go first. If cold taps are dead but hot water still runs (or vice versa), that helps narrow down which pipe run is affected. Watersafe.org.uk has a detailed guide on identifying frozen pipe symptoms and distinguishing them from other faults.

What should I do immediately if a pipe has burst?

Turn off your main stopcock immediately to cut the water supply - usually found under the kitchen sink or where the mains supply enters the property. Then open all cold taps to drain down the system. If water is near any electrics, switch off at the consumer unit. Call a plumber as soon as the water is off. Do not use any electrical appliances in the affected rooms until the area is confirmed safe. Taking these steps in the right order significantly limits the extent of the damage.

Can I prevent my pipes from freezing again in future winters?

Yes, and prevention is substantially cheaper than dealing with a freeze and its aftermath. Lagging exposed pipes with foam pipe insulation is inexpensive and widely available from DIY retailers. Keeping your heating running at a low background temperature during cold spells - even when you're away from home - prevents unheated spaces from dropping to freezing point. In West Sussex, where sustained sub-zero temperatures are less common than in northern regions, basic pipe lagging in loft spaces and garages typically provides adequate protection for most properties.

Does my home insurance cover frozen or burst pipes?

Most standard UK home insurance policies include some form of escape of water cover, which typically covers burst pipes - but the specifics vary considerably between insurers. Some policies cover trace and access costs to locate the problem plus the repair, but not the resulting water damage to floors or walls. Others cover both. Check your policy documents carefully before assuming full cover, report any damage to your insurer promptly, and avoid attempting extensive DIY repairs before damage has been properly assessed, as this can sometimes complicate a claim.
