07863 767134 — that's the one number to remember, staffed 24 hours a day, every day of the year, whether you're standing in an inch of water right now or just want a straight answer about what happens next. Hownslow & Southall Plumber Done Right works out of 66 Winchester Ave, Hounslow, TW5 0HA, dispatching across Hounslow, Southall, Isleworth, Heston, Cranford and Norwood Green. Below: what actually happens on the call, what's worth having ready, how to shut off your own water in the meantime, and exactly how far our coverage reaches.
Answered Live, Any Hour You Call
There's no closing time on this line — the phone is staffed 24 hours, and a real person picks up rather than a recording. That first conversation is short, typically five to ten minutes: what's happening, whether water's actively running, and whether you've found your stopcock. From there an engineer gets moving, and for a real emergency — an active leak, no water, a sewage backup — arrival is as fast as the route from Winchester Ave allows once triage on that emergency plumbing call wraps.
Worth Knowing Before You Dial
A short mental checklist turns a fifteen-minute triage call into a five-minute one:
- Your address, plus which town — Hounslow, Southall, Isleworth or Heston
- A plain description: active water, none at all, a smell, or a drain that won't clear
- Whether you've found the stopcock and whether you could actually turn it
- Any plumbing work done recently — a new boiler, a fixture swap — that might connect to what's happening now
Shutting Off Your Own Water Before We Arrive
Every property has a main stopcock, and locating it before an emergency happens is five minutes well spent. In an older Victorian or Edwardian terrace around Hounslow High Street or Southall, it's usually under the kitchen sink or just inside the front of the property. In a 1930s Heston semi it's more often under the stairs or in a hallway cupboard. In a newer flat, including the Green Quarter developments in Southall, expect a utility cupboard with a modern manifold system. Turn it clockwise until it stops. An older valve can stick, so ease into it rather than forcing it — a seized one can snap. With the stopcock off, open the lowest tap in the property to relieve pressure and drain what's already sitting in the pipes — a small step that can noticeably slow a leak while you wait.
Smelling Gas? Call the National Gas Emergency Service First
If you smell gas anywhere in the property, get everyone outside immediately and don't touch a light switch, a phone, or anything electrical on the way out. Call the National Gas Emergency Service on 0800 111 999 from a safe distance — that's who shuts off supply and makes the property safe. Only once they've confirmed it's safe should you call us on 07863 767134 to arrange any plumbing follow-up. For any other genuine emergency, 999 remains the number.
What Happens Once an Engineer Is On-Site
Diagnosis comes first — a visual check, and for anything not obviously visible, electronic leak detection or a CCTV drain survey — before you're looking at a price. That price comes in writing before any repair work starts, not as a surprise on the invoice afterward, and the finished repair gets checked before the engineer calls it done. For leak detection specifically, that final check matters more than it might elsewhere: a repair can look sound on the surface while the surrounding pipework is still under the same hard-water stress that caused the original leak, so confirming the fix holds is part of the job, not an afterthought.
The Towns We Dispatch Into
No special arrangement needed — this is the standard coverage footprint:
- Hounslow (TW3, TW4, TW5, TW6) — where the shop is, on Winchester Ave
- Southall (UB1, UB2) — about 3 miles north of Hounslow town centre, in the London Borough of Ealing
- Isleworth (TW7) — about 2 miles east of Hounslow town centre, along the A315 towards the Thames
- Heston (TW5) — about 1.5 miles north-west of Hounslow town centre, between the A4 and the M4
Beyond that core footprint, Cranford and Norwood Green are also reachable, along with the wider area around the A4 Great West Road, M4 (nearest access Junction 3), A30, A312 and A315. If your address sits just outside those towns, say so on the call and we'll confirm a realistic window before anyone's dispatched.
Why Calling Now Beats Waiting Until Morning
Thames Water classifies all the water it supplies as hard, and that steady mineral load doesn't announce itself until a boiler, cylinder or joint finally gives out — often at an inconvenient hour rather than a scheduled one. A small drip left overnight in an older Isleworth or Southall property can mean real water loss and damage by morning. None of that is meant to alarm anyone — it's meant to explain why the smarter move is calling at the first sign of trouble instead of waiting to see if it resolves itself. A blocked drain call today, or a leak caught while it's still small, is reliably less disruptive than the cleanup after it's been left alone.
Whatever's going on at your address, the number stays the same: 07863 767134, answered around the clock.

Frequently Asked Questions
How fast does someone actually pick up when I call 07863 767134?
A real person, not an automated menu, typically answers within a few rings, day or night, since the line stays staffed around the clock rather than switching to voicemail after hours. Once you're through, we ask a handful of quick questions — what's happening, whether water's actively moving, and where you're located — and start getting an engineer moving before the call even ends for anything that reads as urgent. That process runs the same at 3pm on a Tuesday as it does at 3am on a bank holiday. Keep your address handy so the first minute of the call goes straight to triage rather than logistics.
What should I have ready before I even pick up the phone?
A clear address is the single most useful thing — including which of Hounslow, Southall, Isleworth or Heston you're in, since postcodes like TW5, TW7 and UB1/UB2 can otherwise get confused over the phone. Beyond that, a plain description helps: is water actively running, is there no water at all, is there a smell, or is a drain backed up. Knowing whether you've already found your stopcock, and whether it turned, changes how we prioritise the call. None of this is mandatory before we'll help — it just shaves minutes off the triage conversation once an engineer's already on the way.
Where is the stopcock likely to be in a typical Hounslow or Southall property?
In an older Victorian or Edwardian terrace around Hounslow High Street or Southall, the main stopcock is usually under the kitchen sink or just inside the front of the property, close to where the supply enters. In a 1930s Heston semi it's often under the stairs or in a hallway cupboard; in a newer flat, including the Green Quarter developments in Southall, it's more often in a utility cupboard or an under-sink cabinet as part of a modern manifold system. Turn it clockwise until it stops — a stiff older valve should be worked gently rather than forced, since a seized one can snap. If you genuinely can't find it, say so when you call and we'll talk you through likely locations for your specific property type.
From the moment I hang up, how long until an engineer is at my door?
Phone triage runs roughly five to ten minutes, and for a genuine emergency — an active leak, no water at all, or sewage backing up — arrival after that is generally as quick as we can manage. Where you're located shifts that window somewhat: a call from central Hounslow tends to run a little quicker than one from further out toward Cranford or Norwood Green, simply because of the drive. Triage happens up front on purpose, so the engineer who arrives is already carrying the right equipment for what you've described rather than improvising afterward. If the situation gets worse while you're waiting, call back — it can move you up the queue.
I can smell gas. What's the very first thing I should do?
Get everyone out of the property immediately, and don't touch a light switch, use your phone indoors, or do anything else that could cause a spark on the way out. From a safe distance outside, call the National Gas Emergency Service on 0800 111 999 first — that's who can shut off supply to the property and make it safe — and reach us afterward on 07863 767134 to arrange any plumbing follow-up once the gas engineer has confirmed it's safe. A genuine gas smell is one of the rare situations where waiting for a booked appointment isn't the right call at all. Stay outside until the gas engineer confirms it's safe to go back in.
Does someone really pick up at 3am, or does it eventually go to voicemail?
It's a real person at 3am, same as at any other hour — this isn't a service that advertises 24 hours while quietly letting overnight calls fall to a machine. That distinction matters most during a genuinely cold snap, when scale-weakened joints and stressed pipework can fail across several properties on the same street within a short window. There's no window to plan around here; if something happens at 2am, that's when to call, not the next morning. The hours we publish — 24 hours — are the hours the phone is genuinely staffed.
Which towns and postcodes actually fall inside your normal coverage area?
Standard dispatch covers Hounslow (TW3, TW4, TW5, TW6), Southall (UB1, UB2), Isleworth (TW7) and Heston, plus Cranford and Norwood Green nearby. Hounslow, Isleworth and Heston fall under the London Borough of Hounslow for building control, while Southall and Norwood Green fall under the London Borough of Ealing — a genuine cross-borough split that factors into anything requiring notifiable work. A property further out in west London is often still reachable — just mention it when you call so we can confirm timing before anyone's dispatched. The phone number stays the same regardless of which town it is.
Water is spreading across my floor right now — what do I do before anyone arrives?
Shut off the stopcock first; every extra minute the water runs adds to the cleanup. Get anything valuable or electrical up off the floor if it's safe to reach, and stay clear of sockets or plugged-in appliances sitting near standing water. If the water seems to be coming up through a floor or wall rather than from a visible pipe or fixture, that can point to a hidden leak, and the same stopcock step still applies while an engineer locates it electronically. Call 07863 767134 as soon as you notice it — the sooner triage starts, the sooner someone's on the road.
Will I actually see a price before anyone starts cutting into a wall or floor?
Yes — an engineer diagnoses what's happening on-site first, then presents a fixed price in writing before touching anything, never a surprise total on the invoice afterward. That's true whether it's a middle-of-the-night emergency or a routine boiler service booked a week out. Nothing obligates you to go ahead once the diagnosis is done; the quote is yours to accept or decline. Once work is agreed, the finished repair gets checked before the job is considered done.
Is 66 Winchester Ave somewhere I can actually visit?
That's our address in Hounslow, TW5 0HA, though most contact happens over the phone on 07863 767134 since a plumbing job gets an engineer sent to your address rather than handled across a counter. The address itself is real and useful if you need it for paperwork, to confirm we're an actual local operation before calling, or simply to look us up. If you're managing a property you don't personally live in — a rental near Southall or a flat you oversee in Heston — having that address on hand alongside your own tends to speed things up. For anything time-sensitive, calling beats writing.
Does it matter whether my address is in Hounslow, Southall, Isleworth or Heston for permitting?
It can, mainly for anything that needs notifying to a council rather than a straightforward repair. Hounslow, Isleworth and Heston all fall under the London Borough of Hounslow, with building control based at Hounslow House on Bath Road; Southall and Norwood Green fall under the London Borough of Ealing instead, a genuinely separate authority. None of that changes how fast we respond to an emergency — the stopcock-and-dispatch process is identical everywhere we cover — but it's worth knowing if a job turns into something requiring notification. Mention your town when you call and we'll flag it if it applies.
