Leaking Tap Repair in Hailsham - DIY Fix or Call a Plumber

Published July 2026 | Leaking Tap Repair Guide

You've noticed the drip. Maybe it's the kitchen mixer that won't quite shut off, or the bathroom tap that's been leaving a rust stain down the basin for weeks. The question sitting in your head is the same one most Hailsham homeowners face: do you roll up your sleeves and fix it yourself, or do you pick up the phone and get a plumber in? It sounds minor, but the wrong call can turn a 15 pound repair into a 500 pound disaster.

Both routes are legitimate. Both have real advantages. The right answer depends on your tap type, your confidence with basic plumbing, and what's actually causing the drip - and that's exactly what this guide breaks down.

Option A - DIY Tap Repair

DIY tap repair means diagnosing the fault yourself and sourcing the parts from a local merchant or online, then carrying out the fix without professional help. For many leaking taps, this is entirely achievable - but only if you know what you're dealing with before you start.

What DIY tap repair typically involves

The most common cause of a dripping tap is a worn washer or a faulty cartridge. On an older pillar tap (the kind with separate hot and cold handles), the fix usually means turning off the water supply, removing the tap head, replacing the rubber washer at the base of the spindle, and reassembling. On modern mixer taps with ceramic disc cartridges, the process is similar but requires sourcing the correct cartridge - which varies by brand and model.

Here's the basic process for a standard washer replacement:

1. Turn off the water supply at the isolation valve under the sink, or at the stopcock if there's no isolation valve.
2. Open the tap fully to release pressure and drain any remaining water.
3. Remove the tap handle - usually held by a grub screw hidden under a decorative cap.
4. Unscrew the gland nut or headgear and lift out the spindle.
5. Replace the old washer with a new one of the correct size (typically 12mm or 3/4 inch for most UK taps).
6. Reassemble in reverse order, turn the water back on, and check for leaks.

Total parts cost: typically between 3 and 20 pounds for a washer kit. Ceramic cartridges run from around 10 to 50 pounds depending on the brand and specification.

Pros of DIY tap repair

• Low cost when the repair is simple - you're paying only for parts.
• Can be done at a time that suits you without waiting for an appointment.
• Builds useful knowledge for future minor repairs.
• Satisfying to sort it yourself, particularly for those already comfortable with basic home maintenance.

Cons of DIY tap repair

• Misidentifying the fault is common. A tap that drips from the spout has a different cause to one that leaks around the base - treating the wrong problem wastes time and money.
• Older taps - particularly those in East Sussex properties built before the 1980s - often have corroded fittings that shear when you try to remove them, turning a minor job into a full tap replacement.
• Cross-threading when reassembling can cause worse leaks than the original problem.
• If your home doesn't have proper isolation valves, cutting off the water means shutting down the whole property supply - which creates more disruption than most people anticipate.
• Getting the wrong cartridge for a mixer tap is an easy mistake, and returns on opened plumbing parts aren't always accepted.

Option B - Hiring a Local Plumber in Hailsham

Bringing in a qualified plumber means handing the diagnosis and repair to someone who does this daily. A good local plumber will identify the root cause quickly, carry the most common parts in their van, and have the job finished in an hour in most cases.

What professional tap repair typically involves

When our engineers attend a leaking tap call-out, the first step is always diagnosis. A dripping spout, a leak from the base, water around the gland nut, and a slow weep from the supply pipe all point to different faults - and treating the wrong one is where DIY attempts often come unstuck.

A typical professional repair looks like this:

1. Inspect the tap and identify whether the fault is a washer, cartridge, O-ring, gland packing, or something further upstream like a faulty isolation valve.
2. Isolate the supply - a plumber will often fit an isolation valve during the visit if one isn't already present, which also benefits future maintenance.
3. Carry out the repair using trade-quality parts, not the low-grade washers that come in supermarket kits.
4. Test under pressure, check for secondary leaks, and confirm the tap operates correctly before leaving.

Where the Voltrade GoFIX diagnostic tool is particularly useful here is in cases where the fault isn't immediately obvious. By logging symptoms against common fault patterns for your tap type and property age, it helps narrow down whether the fix is a simple part swap or something requiring a wider investigation - such as pressure issues from the supply that are causing repeated washer failure.

In terms of cost, a professional tap repair in Hailsham typically costs between 80 and 180 pounds for a standard repair, including call-out and labour. If a tap needs full replacement, expect to pay between 150 and 350 pounds depending on the fixture chosen and complexity of the installation.

Pros of hiring a plumber

• Accurate diagnosis from the start - no guesswork and no wasted trips to the merchant for the wrong parts.
• Trade parts are generally more durable than retail equivalents.
• Work is guaranteed - if the problem returns shortly after, a reputable plumber will return to remedy it.
• A plumber can spot and flag secondary issues during the visit, such as evidence of slow corrosion behind the tap or low water pressure that's stressing the fittings.
• No risk of making the problem worse through incorrect reassembly or overtightened fittings.

Cons of hiring a plumber

• Higher upfront cost, particularly if your issue turns out to be a straightforward washer that you could have replaced yourself.
• You need to be available for an appointment, which doesn't always suit busy schedules.
• Quality varies between traders - it's worth using a platform that vets its engineers rather than picking from an unverified directory.

Side-by-Side Comparison

Here's a summary of how the two options compare across the factors that matter most to most homeowners:

Which Is Right for Your Situation

The honest answer is that this comes down to three variables: the type of tap you have, the age of your plumbing, and your existing experience with basic home repairs.

DIY is a reasonable choice if all of the following apply: you have a standard pillar tap with accessible fittings, the property is relatively modern (post-1990), you can clearly see an isolation valve under the sink, and the leak is coming from the spout rather than the base or supply connection. In this case, a washer kit from your local Hailsham builders merchant and an hour of your Saturday morning can sort it.

Professional repair is the better call in any of these scenarios:

• You have a mixer tap with a ceramic cartridge and you're unsure of the make or model.
• The tap is over 15 years old and the fittings look corroded or discoloured.
• The leak is coming from around the base of the tap, not the spout - this often points to O-ring failure or a cracked body, which is harder to repair cleanly.
• You've already attempted a DIY fix and the leak has returned or worsened.
• There's no isolation valve and cutting off the household supply will cause significant disruption.
• The drip is heavy rather than slow - this suggests a more significant failure that may damage the cabinet or surrounding surface if left.

Properties across East Sussex, particularly older Victorian and Edwardian terraces in the Hailsham area, often have lead or iron supply pipes to the taps that can behave unpredictably when fittings are disturbed. Our engineers frequently find that what looks like a simple washer job uncovers corroded supply pipes behind the wall - something worth bearing in mind before starting DIY work on period properties.

What Hailsham Homeowners Typically Choose and Why

From the jobs our engineers attend across Hailsham and the wider East Sussex area, the pattern is fairly consistent. Most homeowners attempt a DIY fix first for kitchen taps - particularly on more accessible fittings where a previous repair has been done before. When that doesn't resolve the issue, or when the bathroom tap is involved (where access is tighter and fittings are often more complex), they call a plumber.

Mixer taps in particular catch people out. They look simple but the cartridge specification varies enormously by manufacturer, and fitting the wrong cartridge can cause the drip to worsen or the tap to lose pressure on one side. Brands like Bristan, Grohe, Hansgrohe, and Roca all use different cartridge sizes, and even within a brand the cartridge can differ between product ranges. That's a lot of potential for an expensive mistake.

There's also a practical consideration around water waste. A tap dripping at a rate of one drop per second wastes roughly 15 litres of water per day. Given the water metering rates common across this part of East Sussex, that adds up meaningfully on a quarterly bill - which often makes a professional repair pay for itself more quickly than people expect.

Another factor is the kitchen. When the leaking tap is above a base unit full of cleaning products, the risk of water damage to the cabinet below is real. Homeowners in Hailsham with newer fitted kitchens tend to call a plumber fairly quickly for this reason - the cost of replacing a water-damaged cabinet unit well exceeds any saving made by going DIY.

Making Your Decision

Have you identified what type of tap you have and where exactly it's leaking?

This is the most important question. A drip from the spout on a traditional tap almost always means a washer. A leak from the base usually means an O-ring or body seal. A weep around the gland nut suggests the packing needs attention. Each fault has a different fix, and diagnosing incorrectly is the most common reason DIY attempts fail. Take a look before you commit to either route - even a quick video search for your tap type will tell you whether the fix is within reach or not.

How long has the tap been dripping and is there any existing water damage?

A slow drip that's been going a few days is low urgency. A tap that's been weeping for months underneath a cabinet is a different matter - water damage to chipboard units happens quickly and silently. If there's any swelling, staining, or soft patches in the cabinet below your sink, don't delay. Get it looked at professionally. The plumbing repair will be far cheaper than a kitchen refit.

Do you already have the correct tools and parts to hand?

You'll need an adjustable spanner, a flat-head screwdriver, grub screw keys, a replacement washer or cartridge, and ideally some PTFE tape. If you don't have these already and need to buy them, factor that into your cost comparison - a trip to a merchants and a few hours of your time has a real value too. If you already have a basic plumbing toolkit from a previous job, the DIY cost is genuinely low. If you're starting from scratch, the gap between DIY and professional narrows considerably.

What are the consequences if the repair goes wrong?

For a simple pillar tap in good condition, the downside of a failed DIY attempt is usually just a return trip to the merchant and a call to a plumber anyway. But for older taps, mixer fittings, or taps that feed a washing machine or dishwasher, the consequences can be more serious - a fitting that fails under pressure, a supply pipe that cracks when you remove a corroded fitting, or a tap body that shears can cause water damage that dwarfs the original repair cost. If the stakes feel high, trust that instinct.

Frequently Asked Questions

How much does it cost to fix a leaking tap in Hailsham?

A professional tap repair in Hailsham typically costs between 80 and 180 pounds for labour and parts combined, assuming a standard repair such as a washer or cartridge replacement. If the tap needs full replacement rather than repair, costs commonly run between 150 and 350 pounds depending on the tap specification and installation complexity. DIY repairs cost between 5 and 50 pounds for parts alone, assuming you already have basic tools and no complications arise during the job.

Can a leaking tap cause serious water damage?

Yes - particularly when the leak is at the base of the tap or along the supply pipe rather than from the spout. Water that drips inside a cabinet rather than visibly into the basin can saturate chipboard unit bases within weeks, leading to swelling, mould, and structural failure of the cabinet. In older East Sussex properties where the tap connects to lead or copper supply pipes, a persistent drip can also indicate corrosion in the pipework behind the wall, which warrants investigation before it becomes a more significant repair.

What are the most common causes of a dripping tap in UK homes?

The most common cause is a worn rubber washer on traditional pillar taps - the washer compresses over thousands of open-close cycles and eventually stops forming a proper seal. On modern ceramic disc mixer taps, a faulty cartridge is the most frequent culprit. O-ring failure is also common, particularly on swivel-spout kitchen taps where the O-rings around the spout base wear from repeated rotation. Less commonly, a leaking tap can be caused by excessive water pressure stressing the fittings, which a plumber can test and address with a pressure-reducing valve if needed.

How long does a professional tap repair typically take?

In most cases, a professional plumber can diagnose and repair a leaking tap in under an hour. Simple washer replacements on accessible pillar taps are often completed in 20 to 30 minutes. Ceramic cartridge replacements on mixer taps typically take 30 to 45 minutes once the correct part is confirmed. Where the tap requires full replacement or where complicating factors such as corroded fittings or absent isolation valves are present, allow for one to two hours. Our engineers aim to carry common washer and cartridge sizes to minimise the need for return visits.
