Emergency and planned plumbing across London
Emergency repairs, leaks, blockages and considered installations across London properties.
About our plumbing service
Water damage is the fastest way for a well-kept property to lose value, which is why plumbing sits at the centre of what GEM does. Our engineers attend leaks, bursts and failed fittings across central, west and south-west London with the parts and judgement to make a repair permanent on the first visit, not a temporary fix that fails the following month.
Beyond emergencies, we handle the planned side of plumbing properly: replacing tired pipework before it lets go, upgrading stopcocks and isolation valves so future incidents can be contained, and installing sanitaryware, pumps and appliances to a standard that stands up in a managed portfolio. Every job is recorded against the property, so your maintenance history builds into a real asset record.
What happens when you report a leak
Emergency plumbing callouts are triaged for a four-hour operational response, and the phone call starts the work: our operations desk talks you or your tenant through isolating the supply at the stopcock while an engineer is en route, because ten minutes of running water does more damage than most repairs cost. On arrival the engineer traces the fault to its source rather than the point where water appears, which in London's converted terraces and mansion blocks is frequently a floor or a flat away.
Vans carry the fittings that fail most often in the capital's housing stock: flexi hoses, compression joints, ball valves, waste traps and isolation valves, so the majority of emergencies end on the first visit with a permanent repair rather than a return appointment.
Finding leaks without opening ceilings
Where the source is hidden we use moisture mapping and staged isolation to narrow the fault before anything is opened up, and when access is unavoidable we cut cleanly and make good afterwards. Slow leaks are the expensive ones: a weeping joint inside a ceiling void can run for months before the stain appears, and by then the joist ends are wet. The aim is a repair you can forget about, evidenced with photographs, rather than an exploratory hole and an estimate.
Plumbing for landlords and managing agents
For landlords and managing agents on a GEM plan, plumbing callouts are triaged against your subscription and billed at subscriber trade rates, with photographs and completion notes delivered through your portal. Agents authorising work remotely get the evidence trail insurers and freeholders ask for, and repeat issues at the same address are flagged so the underlying cause gets fixed instead of refunded twice.
Questions we hear about plumbing
How quickly can you attend a plumbing emergency?
Emergency callouts are triaged for a four-hour operational response. For active leaks we will talk you through isolating the supply immediately while an engineer is en route.
Do you repair or just replace?
We repair where a repair is genuinely sound, and recommend replacement only when the economics or safety case is clear. Every recommendation comes with a written quotation before work proceeds.
Can tenants report plumbing issues directly?
Yes. On every package, tenants report issues through the portal with photographs and access times, and we triage against your authority limits. You see every report and its status as it happens.
Where do I find my stopcock?
Usually under the kitchen sink, in a hallway cupboard or, in flats, near the entrance or in a communal riser. Finding it before an emergency is worth two minutes today; our engineers label it during any visit so the next incident is containable.
Do you fix low water pressure in flats?
Yes. We diagnose whether the cause is a shared supply, a failing pump, scale or a partially closed valve, then quote the fix. In older mansion blocks the answer is often a booster set or cylinder change rather than new pipework.
