Tap Repair & Replacement in Cardiff

Vetted & insured engineers Clear pricing before work starts G3-qualified for unvented cylinders No gas work — plumbing only

From period pillar taps in Grangetown to monobloc mixers in Splott kitchens, we repair and replace taps across Cardiff, and we'll tell you honestly when a repair beats a replacement.

Cardiff water notes: Cardiff's Welsh Water supply from Brecon Beacons reservoirs is soft — scale is a minor player, and the city's plumbing work leans toward Victorian terrace pipework and the huge Cardiff Bay apartment stock. Cardiff's terraces in Roath, Canton and Grangetown carry classic Edwardian plumbing layouts, while Cardiff Bay and the city centre have added thousands of flats with communal risers and boosted mains. Mains supply here is managed by Welsh Water.

Repairs: washers, cartridges and seals

Traditional compression taps drip because the washer or seat has worn — a re-washer and reseat is a fast, cheap repair. Ceramic disc taps (most modern mixers and quarter-turn taps) drip because the cartridge has worn or scaled; we carry common cartridge sizes and match obscure ones by manufacturer. O-rings cure leaks from the spout base and handles. In Cardiff's water, scale accelerates all of this — which also means a serviced tap lasts visibly longer than a neglected one.

Replacement done properly

A professional tap replacement includes the parts that fail next: new flexible connectors (the old ones are the most common future flood source), service/isolation valves fitted if absent, thread sealing done correctly, and the tap tightened against a supported base rather than a flexing sink. It's the difference between a tap swap and a tap swap you won't revisit. We supply-and-fit or fit your purchased tap across Cardiff at the same labour rate.

The real cost of a drip

That background drip is a running bill: thousands of litres a year, doubled in cost on a meter (supply plus sewerage), tripled in annoyance. Hot-side drips also drain your cylinder's heat. In Cardiff's water the drip also leaves scale tracks that etch chrome and stain ceramics — cosmetic damage that outlasts the fault.

Tap work pricing in Cardiff

From £79 for standard tap repairs in Cardiff, parts included. Replacements are quoted as labour plus tap, so you can compare our supplied ranges with your own purchase like-for-like. If your existing tap is obsolete and a repair means hunting discontinued cartridges, we'll tell you the honest economics up front.

Frequently asked questions

Do you fix outside taps?

Yes — repairs, replacements and new outside tap installations with the legally required double-check valve for backflow prevention, plus an internal isolation point so you can drain it each winter.

My mixer tap has low pressure on hot only — why?

Common on combi and gravity systems: scale or a blocked hot-side inlet filter, a kinked or degraded flexi, or the tap's internal flow restrictor. It's diagnosable in minutes with the tap head off.

Is a constantly dripping tap really worth fixing?

On a metered supply, unambiguously: thousands of litres a year, charged as both water and sewerage, plus heating cost on hot taps. The repair usually costs less than the annual waste.

Can you fit a tap I bought online?

Yes — supply-your-own is fine and priced at the same labour rate. We'll check compatibility (tail lengths, hole spacing, pressure requirements) before removing the old tap, so a mismatch is caught before the sink is out of action.
