Tap & Sink Repair in Watford
A dripping tap sounds minor at noon and unbearable at 3am. [Rapid Plumber Watford](/) answers on 07360 270663 at every hour, finds the independently owned partner company closest to your street and sends you its name by text before it arrives. Taps, mixers and sink wastes across Watford, Holywell and Leggatts are all within its reach.
Published UK guidance puts a leaking tap repair at about £60 to £120, with a new tap installed at £80 to £250. These are published ranges, not our prices. The partner company works out whether a new washer or cartridge will do, quotes the job in writing, and tells you honestly if the tap is simply spent.
Hard water is the chief culprit locally. Tapwaterdata gives the Watford South zone, which covers most of WD18, a hardness of 351 mg/l as calcium carbonate, while the smaller Watford North zone reads 323 mg/l. Both are very hard, and both leave scale on ceramic discs, cartridges and aerators that stiffens handles and makes taps drip.
The fix depends on the tap. A traditional pillar tap needs a new washer or seat, a mixer or a monobloc usually needs a cartridge, and a ceramic-disc tap needs its discs replaced. Getting the type right first time is the difference between a ten-minute fix and a second visit.
A leak under the sink is often a supply pipe or a compression joint rather than the tap, and that crosses into leak detection. A tap that cannot be shut off at all can be treated as urgent.

What We Do
Tap and Sink Faults We Arrange Repairs For
Most visits come down to one of three things.
Dripping and Leaking Taps
A drip from the spout is a worn washer, seat or cartridge. A leak at the base of the handle is usually a failed O-ring. Fixing it promptly stops waste, avoids staining on the basin and prevents a drip from turning into a corroded seat.
Stiff Handles and Weak Flow
A handle that has gone stiff, or flow that has dwindled, often means scale has clogged the cartridge or the aerator. Descaling can help, but a cartridge that has hardened is cheaper to replace than to coax back to life.
Sink Wastes and Trap Leaks
A cabinet that smells damp or a bowl that drains slowly may have a cracked waste, a perished seal or a loose trap. Pipework under the sink is checked for compliance with the Water Supply (Water Fittings) Regulations 1999 while it is open.
The Benefits
What Happens at a Tap Visit
Short job, clear steps.
Identify the Tap
The partner company confirms the tap type and brand, isolates the supply, and removes the headgear or cartridge to see exactly what has failed. Sending us a photo helps it bring the right part.
Fix or Replace
If a washer or cartridge is all that is needed, the repair is quoted at that level. If the body is corroded, the plating is worn or parts are discontinued, a replacement tap is quoted in writing as an alternative.
Leave It Tidy
The new part is tested under pressure, the surrounding joints are checked dry and any scale is wiped away. You can keep the old parts if you want to see what failed.
Good to Know
Tap Problems Worth Fixing Early
A small drip becomes a large cost.
Signs a Tap Needs Attention
Watch for these between cleans.
- A steady drip even when the handle is fully shut
- Water seeping around the base or spindle of the tap
- A handle that has become hard to turn
- Weak or split flow from the spout
- White crusty scale around the spout or aerator
Quick Things You Can Do
Simple steps before the partner company arrives.
- Find the small isolation valve under the sink and close it
- Put a bowl under the drip and check the cupboard below
- Take a photo of the tap, including any brand name
- Do not force a seized handle with pliers
- Clear the area under the sink for access
Why Us
Tap Repair Across Watford
Every kitchen and bathroom is a bit different.
Cassiobury Kitchens
The 1930s semis around Cassiobury Park Avenue often have the original kitchen layout extended by later additions, which means long supply runs to a single sink. Those runs can keep a tap's hot flow cool, and a fix is sometimes about the pipework behind it.
West Watford Terraces
Rear-kitchen extensions on the terraces off Vicarage Road keep sinks a long way from the stopcock. The partner company will ask where your isolation valves are so it can shut off just the tap rather than the whole house.
North Watford Bathrooms
Victorian and Edwardian terraces off St Albans Road often have basins that were added or moved a century later. Mixed old and new pipework under a basin is a common source of slow leaks.

What Is Tap and Sink Repair?
Tap and sink repair is the diagnosis and replacement of the parts that control and carry water at a basin or sink: washers, cartridges, discs, O-rings, aerators, tails, traps and wastes. It keeps the existing tap in service where possible and replaces the whole fitting only when it cannot be saved.
Taps and their connections must meet the Water Supply (Water Fittings) Regulations 1999, which exist to prevent waste and contamination. Fittings should be WRAS-approved, and BS EN 806 sets out the design principles for water systems inside buildings.
What Affects the Price of Tap Repair
The Type of Tap
A washer change on a traditional tap costs far less than a cartridge on a premium mixer. Published UK guidance puts repair at £60 to £120 and a replacement at £80 to £250.
Access and Pipework
A tidy cupboard with working isolation valves makes a quick job. If the valves have seized, the partner company may fit new ones, which adds to the price but makes any future repair simpler.
After the Repair
The tap is run hot and cold, checked for drips and tested with the plug in and out. You are given a written account of what was changed, and the invoice is the partner company's own.
Tap Types and How Each One Fails
Pillar Taps With Washers
The traditional pair of separate hot and cold taps relies on a rubber washer pressing against a seat. When the washer hardens or the seat pits with scale, the tap drips. This is the cheapest repair, though a badly scored seat may need a reseating tool or a new tap.
Ceramic Disc and Quarter-Turn Taps
Two ceramic discs slide against each other to control flow. They are tough, but grit and scale scratch them, which causes weeping from the spout. The cartridge is replaced as a unit and the job is usually quick.
Mixer and Monobloc Taps
A single lever controls temperature and flow through one cartridge. Mixers are the most common kitchen fitting, and they fail by dripping, stiffening or swinging loose at the base. Quoting for the right cartridge needs the brand, so a photo saves a second visit.
Sink Wastes, Traps and Under-Sink Leaks
Why the Cupboard Floor Gets Wet
Many kitchen "tap leaks" are in fact waste joints, flexible tap connectors or a loose trap. A damp cupboard base, a musty smell or swollen chipboard is the clue. The partner company checks each connection with a dry tissue, because that finds a slow weep that the eye misses.
Flexible Connectors and Isolation Valves
The short braided hoses under a tap can corrode or split without warning. Replacing them while the cupboard is open costs little, and fitting an isolation valve to each means a future repair never needs the whole house shut off.
Frequently Asked Questions
How much does tap repair cost in Watford?
Published UK guidance for 2026 puts a leaking tap repair at roughly £60 to £120, with a new tap installed at about £80 to £250. These are published ranges, not our quotes, and no Watford-specific tap price has been verified. The partner company confirms the figure in writing before it starts. Where a tap is too far gone to repair, the written quote offers a replacement as an alternative, so you can compare.
Why does my tap keep dripping?
A drip usually means the washer, seat or ceramic disc inside the tap has worn or been scarred by scale. Watford's very hard water, 351 mg/l in the Watford South zone and 323 mg/l in the Watford North zone, speeds up that wear. Replacing the worn part normally stops the drip. Cold-water and hot-water taps wear at different rates, and the hot side tends to fail first because heat speeds scale.
Can limescale damage a tap?
Yes. Scale builds on cartridges, discs and aerators, making handles stiff and flow weak, and in time it can score the surfaces that seal the tap. Regular cleaning helps, but once a cartridge has hardened it is cheaper to replace than to keep descaling. A dishwasher or kettle in the same house will usually show the same scaling, which is a useful clue that the water is the cause.
Should I repair or replace a leaking tap?
If the body is sound and the fault is a washer or cartridge, repair is the cheaper choice. If the finish is flaking, the body is corroded or parts are no longer made, a new tap is the better buy. The partner company can quote both and explain the difference. Photographs of the tap help the partner company judge this before it arrives, which can save a wasted visit.
Can you fix a mixer tap?
Yes. Most mixer and monobloc taps use a replaceable cartridge, and the partner company will usually identify it from the brand or a photo. If the cartridge is obsolete, a replacement tap is offered instead. Brand names are often stamped under the handle or on the base, so a quick look or a photo before you ring is enough.
Can a tap be repaired out of hours?
The line is answered at every hour, and we ask the nearest partner company if it can attend. We cannot promise an arrival time. If the tap cannot be shut off, close the isolation valve under the sink or the stopcock and call us. If water is escaping badly, close the isolation valve under the sink first, and then ring us and we will tell you what happens next.
How do I stop the water if the tap won't shut?
Look under the sink for the small isolation valve on the pipe feeding the tap and turn the slot a quarter turn with a screwdriver. If there is none, shut the main stopcock, usually under the kitchen sink or by the front door. Then call us on 07360 270663. Turn the stopcock clockwise to close it, and run a tap to drain the pipes once it is off.
Do you fit new taps as well as repair them?
Yes, the partner company can fit a replacement tap if the old one is beyond repair. Fittings should be WRAS-approved and installed in line with the Water Supply (Water Fittings) Regulations 1999. The price is quoted in writing before the work. Replacement is quoted in writing and the partner company will remove the old tap and dispose of it unless you want to keep it.
Why is the hot tap slow but the cold tap fine?
Scale in the hot-side cartridge or in the boiler's heat exchanger is a likely cause. Low pressure, a partly closed valve or a restriction in the pipework can also be responsible. The partner company tests flow at the tap and traces it back. If both taps are slow, the problem lies upstream, in the stopcock, the pipework or the pressure feeding the property.
Do I need to be home for the repair?
Yes, someone should be at the property to give access and to approve the quote. The partner company's name is texted to you before it arrives. If another person is letting it in, tell us when you ring. If someone else is letting the partner company in, tell us on the call so that the person is expecting it.
Can a leaking tap damage my cabinet?
It can. A slow drip or a leak under the sink swells chipboard carcasses, stains worktops and breeds mould. Fixing the leak early is cheaper than replacing a kitchen unit. Putting a bowl under a drip is a sensible stopgap, but the cupboard base should be dried and checked for damp once the repair is done, because chipboard that has swollen does not shrink back.
What if the tap leaks again after repair?
Ring us on 07360 270663 and we take it up with the partner company that did the work. Because the number stays on the job, you do not need to find another contact. Any further work is quoted in writing before it begins. Keep the partner company's written account to hand, because it makes any follow-up conversation quicker.
