A blocked sink is rarely dramatic like a leak… it’s just relentless. The water sits there, the smell creeps in, and you end up doing that sad little “scoop-and-dump” routine with a mug. I’ve been to plenty of homes in Petts Wood and Shortlands where it starts as “just slow” and turns into “we can’t wash up”.
Most of the time it’s a build-up of fat/grease (kitchens), soap sludge (bathrooms), or limescale in older pipe runs. The trick is clearing it properly — not masking it for a week.
If you’re stuck near The Glades or driving in via the A21 and thinking “please, just someone nearby” — call 07706 889 614. I’ll tell you straight what’s realistic time-wise.
Kitchens in Bromley terraces and Orpington semis get hit with the same pattern: warm grease goes down as a liquid, then cools and lines the pipe like candle wax. Add a bit of rice, coffee grounds, and washing-up foam… and you’ve got a proper restriction over time.
Bathrooms are different. Soap, toothpaste, shaving foam and hair make a sticky sludge that loves the inside of older waste pipes. In some parts of Kent/South East London you’ll also get harder water, so limescale builds on the pipe wall and gives that sludge something to cling to.
Step one is working out where the restriction is: the trap under the sink, the short waste run, or further down the branch line. A lot of plumbers guess. I don’t like guessing — it wastes your money and my time.
For kitchens, I’m looking for grease build-up (FOG: fats, oils and grease) and food debris trapped in the pipe. For bathrooms, it’s usually soap sludge + hair + scale. Different “recipes”, same outcome.
“No mess left behind. Honestly, that was my biggest worry.”
— Orpington homeowner
“Explained what caused it and how to stop it happening again.”
— Bromley customer
“Didn’t just ‘poke it’ and leave. It actually drains properly now.”
— BR1 flat
Sometimes it helps, sometimes it just softens grease and shifts it further down where it cools again. If it’s been slow for weeks, boiling water rarely “solves” it — it just buys time.
Often it’s biofilm (a slimy layer) sitting in the trap or waste pipe. It doesn’t need a full blockage to smell. A proper clean-out of the trap and waste run usually fixes it.
On its own, limescale is more like “pipe narrowing”… but it gives soap sludge something to stick to. Over time the combination can create a stubborn restriction.
Repeat patterns usually mean there’s a condition in the line — not just random bad luck. This is exactly why we built this page: the recurring blockage diagnosis guide.
Yes, but tell me you’ve got one. Disposers change what can sit in the line and where blockages form. A quick heads-up avoids wasted time on arrival.
Fastest route is the phone: 07706 889 614. If you’re mid-workday, send the form and I’ll ring back between jobs.
If you’re seeing multiple fixtures slowing or backing up, don’t book this as a “sink job” — use this page instead: the main page for outside drainage emergencies.
Include “kitchen” or “bathroom”, plus your nearest landmark.
