Not every plumbing problem requires an emergency call-out, but you should seek urgent help when the problem could cause significant property damage, interrupt an essential water supply or create a safety concern.
Common plumbing emergencies include:
If you're unsure how urgent the problem is, contact Keystone London and explain what has happened. We can help determine the appropriate next step.
The cost of an emergency plumber in London depends on the type of problem, the work required, when the engineer is needed and whether replacement parts are required.
A straightforward leaking valve may take less time to repair than a concealed leak or burst pipe that requires further investigation. Accessibility and the extent of any damage can also affect the work involved.
Burst pipes and major water leaks can cause significant damage when water spreads through floors, walls and ceilings. Finding and controlling the source quickly can help limit further damage to the property.
Our emergency plumbers investigate leaking pipework, joints, valves and connected plumbing to identify the likely source. Depending on the fault, the repair may involve replacing damaged pipework or fittings, repairing a failed connection or isolating the affected section.
Signs of a Hidden Water Leak
Water Stains
New marks or discolouration appearing on ceilings or walls.
Damp Patches
Persistent damp around floors, walls, cupboards or plumbing fixtures.
Changes in Water Pressure
An unexplained drop in pressure can sometimes indicate a problem within the system.
Unexplained Water Usage
A noticeable increase in water use without an obvious reason may warrant investigation.
