Leak detection in Cherwell.

Thames Water's chalk-aquifer supply, running at 270 to 320 ppm CaCO3 across Cherwell, produces progressive limescale build-up inside copper and plastic supply pipework alike. In Banbury's older OX15 and OX16 terraces, original lead communication pipes to the boundary remain on some properties, and galvanic action at copper-lead junctions is a documented source of slow supply-side leaks that show first as rising damp rather than any visible water. In the Bicester corridor, the new-build density has brought pressure-tested plastic systems, but micro-failures at push-fit joints – particularly where pipework runs beneath concrete oversite – are reported with notable regularity.

We trace supply leaks without opening walls or excavating blindly. Acoustic correlators locate the sound signature of a pressurised leak to within centimetres; thermal imaging identifies temperature differentials through floor and wall surfaces; tracer gas finds breaches in runs that carry no acoustic signal. Every investigation concludes with an insurance-grade written report – precise leak location mapped to a scaled drawing, pressure data, and a plain-English findings summary accepted by mortgage lenders and loss adjusters. There is no callout fee; pricing is fixed after the initial assessment. See /pricing.
