Repair Dripping Mixer Tap: Fast Cartridge, O-Ring & Tap Replacements Across MK, Beds & Bucks
Fed up with a constant dripping mixer spout, water pooling around the base of your swivel tap, or stiff quarter-turn lever handles? Severe chalk limescale across Milton Keynes, Bedfordshire, and Bucks scores ceramic discs and perishes rubber O-rings. We repair or replace faulty mixer taps on the first visit with £0 call-out charge.
Why Is Your Mixer Tap Dripping or Leaking?
Modern monobloc, dual-lever, and single-lever mixer taps rarely use old-fashioned rubber washers. Instead, they fail in one of three specific places due to hard-water scale:
Scored Ceramic Disc Cartridges (20/24/28 Spline)
If water keeps dripping from the spout nozzle when the lever is turned off, grit or hard-water calcium has scored the microscopic twin ceramic discs inside the brass valve cartridge.
- Quarter-turn hot & cold brass ceramic gland swaps
- 35mm & 40mm single-lever plastic joystick cartridges
- Fixes stiff, grating, or spinning mixer tap handles
Perished Swivel Spout O-Rings & Bonnet Seals
If water oozes out from the neck swivel joint whenever the tap is running and pools around your worktop or basin, the internal nitrile rubber O-ring seals have split.
- Full spout removal, descaling & twin O-ring replacement
- WRAS-approved silicone grease lubrication for smooth swivel
- Stops water seeping through the tap hole into the cabinet below
Weeping Flexi-Tails, Seized Valves & Full Tap Swaps
When a budget mixer tap has a pitted internal brass seat, seized grub screws, or corroded M10/M12 braided flexi-tails, replacing the complete mixer tap is faster and more economical.
- Complete monobloc basin, bath & kitchen mixer installations
- Upgrading seized or missing 15mm isolation ball valves
- Securing loose/spinning taps with brass horseshoe backnuts
Our 4-Step Mixer Tap Repair Process
Send us a quick photo of your mixer tap on WhatsApp before we arrive—we can identify your exact spline/cartridge type or bring a new replacement mixer tap on the van.
Safe Water Shut-Off & Valve Inspection
We isolate the hot and cold feeds under the sink or at the mains stopcock. If your property lacks accessible under-sink isolation valves, we can install them during the repair.
Non-Destructive Shroud & Valve Removal
Hard-water limescale often welds chrome decorative shrouds and brass cartridges into the tap body. We use specialist pullers and descaling agents to extract seized parts cleanly.
Precision Cartridge Match or Full Tap Upgrade
We match the thread diameter (1/2" or 3/4"), spline count, and stem height—or, if the tap body is corroded internally, install a brand-new mixer tap on the spot.
Descaled Aerator & Dry Cabinet Sign-Off
We clean out your blocked spout aerator diffuser for smooth splash-free flow, pressure-test all under-sink connections, and cover our workmanship with a 3-month guarantee.

Real examples of how we stop constant hot-water drips, boiler short-cycling, and swollen kitchen worktops.
Field Case Study 01 • Milton Keynes (Shenley Brook End)
Hot-Side Quarter-Turn Mixer Drip Firing Combi Boiler Every 10 Minutes
The Fault: A homeowner's dual-lever monobloc mixer tap had a rapid hot-water drip that kept triggering their combi boiler throughout the night and staining the sink basin with limescale.
The Outcome: The customer WhatsApped a photo of the tap levers. Jimmy arrived within 50 minutes, isolated the hot feed, extracted the calcified 1/2" 20-spline brass ceramic disc gland, and fitted a matched pair of hot and cold ceramic cartridges plus a new spout O-ring kit.
Field Case Study 02 • Dunstable & Luton Border
Seized Monobloc Mixer & Swollen Under-Sink Cabinet Rescue
The Fault: Water had been secretly seeping past a perished mixer tap base seal for months, corroding the steel clamping plate underneath and dripping onto the cupboard shelf.
The Outcome: Because the old tap body threads were rotted solid with verdigris and limescale, Jimmy cut out the seized backnut from below, installed two new quarter-turn 15mm isolation valves, and mounted a brand-new heavy-duty monobloc mixer tap in under an hour.
"Sent Jimmy a picture of our dripping bathroom and kitchen mixer taps on WhatsApp in the morning. He gave a fixed price straight away, came out that afternoon with the exact ceramic cartridges on his van, and stopped both drips in 30 minutes. Brilliant local service."
"Our mixer tap was leaking around the swivel neck and soaking the worktop every time we washed up. Jimmy replaced the internal O-rings, fitted proper shut-off valves under the sink, and tightened up the loose tap base. Zero call-out fee and super tidy."
Frequently Asked Questions: Dripping Mixer Tap Repairs
Everything you need to know about repairing vs. replacing a leaking mixer tap.
Why does my mixer tap still drip even when I push the lever firmly off?
Unlike traditional pillar taps that compress a soft rubber washer, modern mixer taps use two ultra-smooth ceramic discs inside a cartridge. When hard-water limescale or pipe debris scratches those ceramic discs, pushing the handle harder will never seal the gap—and forcing it can snap the lever spline. Replacing the internal ceramic disc cartridge restores a 100% watertight seal.
Is it cheaper to repair a dripping mixer tap or replace the whole tap?
In around 70% of call-outs, replacing the internal ceramic disc cartridges or spout O-rings is the fastest, most cost-effective fix—especially for branded taps (Bristan, Franke, Blanco, Grohe, Crosswater). However, if you have an older unbranded tap where limescale has fused the chrome shroud solid or pitted the internal brass body, fitting a complete new mixer tap is often better value and gives you a brand-new manufacturer warranty.
Can I supply my own replacement mixer tap for you to fit?
Yes, absolutely. Whether you have already bought a new bathroom basin mixer, bath filler, or kitchen monobloc tap—or you want us to supply and fit a reliable trade-grade mixer tap straight from our van—we charge £0 call-out fee and give you a fixed installation price upfront.
