Water Leak Detection in Stevenage

What the work involves

• Acoustic survey with ground microphones along the route
• Tracer gas injection for plastic pipes and quiet leaks
• Thermal imaging and moisture profiling where relevant
• A marked dig location and a written findings report

When you need it

• The meter runs with everything off
• A damp patch, warm spot or sinkhole with no obvious source
• The water company says the loss is on your side
• You need evidence for an insurance trace-and-access claim

What leak detection costs in Stevenage

A professional detection visit typically runs £150–£400 — thermal imaging for hot and heating pipes, acoustic listening, tracer gas that passes through concrete and tile, endoscope cameras into voids, moisture mapping and pressure or consumption tests locate the leak point precisely, so the repair is one small hole instead of an exploratory trench. On any metered supply, the detection fee is usually recovered many times over in stopped losses. Two pricing models dominate: no-find-no-fee detection, and a fixed find-and-fix price — ask which one the quote uses, and check the no-find guarantee’s scope: internal hot and cold is standard, while heating circuits and the incoming main are often excluded. For insurance claims, an independent report — commissioned by you rather than the insurer — carries weight precisely because it answers to neither side. Check your buildings policy for ‘trace and access’ cover too — most include it, and it pays for locating the leak and opening up to reach it (usually not the pipe repair itself; scope varies). Insurers expect the photographed report good firms provide as standard.

Try the two-minute test first

Turn off every tap and appliance, then watch the meter. Movement with everything off means water is escaping between the meter and your taps — usually the underground supply pipe — and that is exactly the job to post. And not every ‘leak’ is a pipe — failed shower waterproofing mimics one precisely, so ruling pipework in or out is half the value of a proper visit.

Water Leak Detection in Stevenage — common questions

How accurate is leak detection?

On a traceable route a good engineer will usually mark within 0.5m — the difference between one small hole and a series of exploratory excavations.

How do professionals find a hidden leak?

Acoustic ground microphones, tracer gas and correlation between sensors — the point is pinpointing, so the excavation is surgical.

Is a leak always on my side?

No — the main and the communication pipe up to your boundary belong to the water company, and faults there are theirs to fix free.

Can I claim a leak allowance?

Metered customers can usually claim an allowance from Affinity Water for water lost to a genuine supply-pipe leak once it is fixed — ask when you report it, and keep the repair invoice.
