How much does it cost to find and fix a leak in London?

Leak work is charged by time, at £60 + VAT for the first 30 minutes and £30 + VAT for each additional 30 minutes, and many accessible leaks, such as a dripping compression fitting or a leaking trap, are traced and fixed within the first half-hour to an hour.

• £60 + VAT for the first 30 minutes
• £30 + VAT per additional 30 minutes
• Saturday appointments charged at the same weekday rate
• No separate call-out fee
• An estimate is given once the source is found, before the repair

A worked example: a leaking compression joint under a sink that is dripping onto the cupboard floor is usually traced and resealed or remade within the first half-hour to an hour, so around £60 to £90 + VAT plus any fitting. The reason a leak is charged by time rather than a flat price is that the finding is the job: where water shows is often not where it leaks, because it runs along a pipe or a joist and drips at the lowest point, so the skill and the time go into tracing it back to the true source before a single fitting is touched. Once found, an accessible joint or fitting is quick to put right, which is why most accessible leaks are a single short visit.

How we find where a leak is really coming from

Silver Saints trace a leak back to its true source rather than guessing from where the water shows, because water rarely drips directly below the fault. On a leaking pipe the water runs along the pipe or across a ceiling joist and falls at the lowest point, so a brown watermark in the middle of a ceiling can be fed by a leak a metre or more away. We work it back methodically: checking whether the leak is constant or only appears when a fixture is used, which separates a pressurised supply leak from a waste or appliance leak, then isolating sections to pin down the joint, fitting or seal at fault. Getting that right first is what stops a customer paying to open up the wrong spot.

What kinds of leaks do you repair?

Silver Saints repair accessible plumbing leaks from supply pipes, waste pipes, pipe joints, compression and push-fit fittings, tap and valve connections, traps, overflows and the plumbing connections to water-using appliances. Common jobs are a weeping compression joint, a failed push-fit O-ring, a perished tap connector, a cracked or loose trap under a sink or bath, and an overflowing or leaking tank or cistern. Where a leak is behind tiling, under a floor or buried in a wall, we explain what access is needed before opening anything up, so you know the scope before the work starts.

Why is there a brown watermark on my ceiling?

A brown watermark on a ceiling is water from a leak above tracking along a joist or pipe and soaking through at the lowest point, and Silver Saints trace it back to the source, which is often a bathroom waste, a pipe joint or, in a flat, a leak from the property above. The stain marks where the water collects, not where it escapes, so the repair starts with finding the actual leak rather than treating the stain. In a converted flat or mansion block a ceiling leak frequently originates in the flat above, and we identify that clearly so it can be raised with the right party.

Leaks across London property types

Where leaks happen and how hard they are to reach varies sharply across London building stock. In Victorian and Edwardian terraces across Wandsworth, Hackney, Islington and Camden the pipework is often a patchwork of old and new, with original lead or steel runs joined to later copper and plastic, and the weak points are the joints between materials and the buried runs under suspended timber floors. In mansion blocks across Kensington, Chelsea and Marylebone pipes are frequently boxed in or run through communal voids, so a leak in one flat shows in another and tracing the source matters most. In 1960s and 1970s blocks the original galvanised pipework can corrode at the threads. In modern new-build flats around Nine Elms, Battersea and Canary Wharf the plumbing is mostly push-fit and manifold-fed, where a leak is usually a fitting that was not fully engaged. Knowing the likely weak point by property type is what makes the trace quick.

Stopping the damage while we work

The first thing on a live leak is to stop it getting worse, so Silver Saints isolate the water at the nearest service valve or the stopcock before opening anything up, which limits the damage and lets the repair be done dry. Knowing where the isolation points are, the under-sink service valves, the appliance valves and the main stopcock, and confirming they actually hold, is part of the job, because a seized stopcock is a common nasty surprise on older London properties. Where a fitting needs replacing we remake it properly rather than over-tightening a failing joint, since a compression nut cranked down on a worn olive will weep again within weeks.

Combine a leak repair with other plumbing jobs in one visit

Because a Silver Saint is multi-trade, a leak visit is a sensible moment to deal with the related plumbing that caused or surrounds the leak, in the same appointment and with no second call-out fee. A leak from a worn tap connection is often best solved by replacing the tap rather than nursing the joint. A leak where a basin or worktop meets the wall usually needs resealing the basin or sink once the pipe is fixed. And a slow waste leak is frequently tied up with a partial blockage, so we can sort a blocked sink or waste at the same time. Tell us everything when you book and we will arrive equipped for the lot.

Can you find the source of a leak even if it is not obvious?

Why is there a brown watermark on my ceiling?

A brown watermark on a ceiling is water from a leak above tracking along a joist or pipe and soaking through at the lowest point, and Silver Saints trace it back to the source, which in a flat is often a leak from the property above.

Can you tell if a ceiling leak is coming from the flat above?
