Leak Detection Surrey — Trace and Repair Hidden Water Leaks
A hidden water leak can cause extensive damage to a property before it is even found. Water seeping from a concealed pipe under a floor, inside a wall cavity, or above a ceiling can cause timber rot, plasterwork damage, mould growth and structural problems — often without any visible sign of water until the damage is already significant. At 247 Plumber Surrey, our specialist leak detection service uses professional equipment to locate hidden leaks accurately and with minimal disruption, covering Guildford, Woking, Epsom, Camberley, Farnham, Redhill, Reigate and all surrounding Surrey areas.
Finding a hidden leak used to mean significant damage to decorations and structure — floors lifted, tiles broken, walls cut open — in the search for the fault. Today, specialist acoustic leak detection equipment allows us to pinpoint a leak to within a very small area before any access is made, greatly reducing the cost and disruption of trace and access work. In many cases we can locate a leak without lifting a single floorboard or removing a single tile.
Signs You May Have a Hidden Leak in Your Surrey Property
Unexplained Increase in Water Bills
If your water bill has increased noticeably without any change in your household’s water usage, a hidden leak is a likely explanation. Even a small pinhole leak in a copper pipe under a concrete floor can lose hundreds of litres per day. Your water company can sometimes provide meter reading data to help confirm whether there is an ongoing loss.
Damp Patches on Walls, Floors or Ceilings
Damp patches that appear or grow despite no obvious external water source — such as rain ingress — suggest an internal pipe leak. Patches that are warm to the touch in a floor often indicate an underfloor heating leak or a hot water pipe leak. Ceiling staining below a bathroom frequently indicates a slow leak at a joint or through a waste fitting that has not been properly sealed.
Constantly Running Water Meter
If you turn off all taps and appliances in your home and the water meter dial continues to move, water is leaving your supply somewhere it should not be. This is a reliable early indicator of a hidden leak. We can help you carry out this check and, if a leak is confirmed, trace its location and repair it.
Mould or Mildew in Unexpected Places
Mould growing on walls or ceilings in areas that are not normally exposed to moisture — hallways, bedrooms, inside wardrobes — can indicate a slow hidden leak providing a persistent source of moisture to the affected area. Left untreated, mould can cause respiratory health problems and structural damage to wall surfaces and timbers.
Our Leak Detection Methods
Acoustic Leak Detection
Acoustic detection equipment picks up the sound of water escaping under pressure from a pipe and allows us to pinpoint the leak location by mapping sound intensity across a surface. The engineer moves the listening device systematically across the floor or wall, and the equipment identifies where the sound is loudest — directly above or beside the leak. This is the most accurate and least invasive method for locating leaks in pipes under concrete floors or behind plastered walls.
Thermal Imaging
A thermal imaging camera detects differences in temperature across surfaces. A hot water pipe leak under a floor creates a warm zone visible on the thermal image, while a cold water leak creates a cooler zone as evaporation lowers the temperature slightly. Thermal imaging is particularly useful for locating underfloor heating leaks and for identifying the approximate area of a leak before acoustic detection is used to pinpoint it precisely.
Pressure Testing
Pressure testing confirms the presence and severity of a leak in a plumbing or heating system. The system is isolated, pressurised to a test pressure and monitored over a period of time. A drop in pressure indicates a loss somewhere in the system. Combined with acoustic detection, pressure testing helps us confirm we have found the right location before any access work begins.
Trace and Access Insurance Claims in Surrey
Many home insurance policies in Surrey include cover for trace and access — the cost of finding and accessing a hidden leak, including reinstatement of the surfaces disturbed in the process. The actual repair itself is usually covered under buildings insurance. If you believe you have a hidden leak and have home insurance, contact your insurer before commissioning leak detection work, as they may have approved contractors. We produce written reports with photographs documenting the leak location and the damage found, which can support an insurance claim.

How do you find a hidden leak without damaging my property?
We use acoustic detection equipment and thermal imaging cameras to locate leaks with precision before any access is made. In most cases we can identify the leak location to within a small area, minimising the amount of floor or wall that needs to be opened up to access the faulty pipe.
Does my home insurance cover leak detection in Surrey?
Many home insurance policies include trace and access cover, which pays for finding and accessing a hidden leak. Check your policy documents or call your insurer before booking. We produce written reports with photographs to support insurance claims.
