Service Overview

What it is.
Who it's for.
Why it matters.

What it is

Leak detection and repair on water systems, gas pipework and heating circuits, from a slow dripping tap to a hidden pinhole under the floor losing 50 litres a day. We trace, isolate, repair and pressure-test.

Who it's for

Anyone seeing damp patches, hearing running water with everything off, watching their water meter spin unexpectedly, or smelling gas. Insurance claimants needing leak trace and access reports.

When you need it

As soon as you suspect a leak. Hidden water leaks cost roughly £50/month on the water bill and quietly destroy floors, joists and ceilings within weeks. Gas leaks are an immediate emergency, call now.

Why professional matters

Most water damage claims start as a leak that was 'going to get sorted next week'. Find it fast, fix it once, and you avoid the £8,000 ceiling and floor replacement that follows.

What Happens If You Leave It

The cost of doing nothing
is always higher than acting.

Structural damage

Water in floor joists or ceiling cavities causes rot within weeks. Replacement runs into thousands; early detection costs hundreds.

Mould and health risk

Damp from undetected leaks grows mould inside walls, respiratory issues, allergies, asthma triggers.

Wasted water (and money)

A pinhole leak can lose 70+ litres a day. On a water meter, that's £25/month draining into your floor.

Gas leak escalation

Even a tiny gas leak is an explosion risk and a CO risk. Never put it off, call immediately.

Our Process

A clear, step-by-step system.

No surprises, no shortcuts, the same proven workflow on every job.

Phone triage

Describe the symptoms, visible damp, sound of water, smell of gas, meter movement. We'll prioritise accordingly.

On-site inspection

Visual inspection of accessible pipework, fittings, appliances and damp patches.

Detection & tracing

Non-invasive leak detection: acoustic, thermal imaging, moisture mapping, pressure testing, minimal damage to find the leak.

Quoted repair

Fixed-price quote for the repair, written down before we cut into anything.

Repair & pressure test

Clean repair to a watertight finish, system pressure-tested, area dried and tidied. Insurance report on request.

The Benefits

Why the right engineer
changes the outcome.

Same-day attendance

Most leaks attended within 24 hours, emergencies within hours.

Non-invasive detection

We find the leak before we cut into anything, minimal damage, maximum chance of one clean repair.

Fixed-price repair

Quote in writing before any work. No hourly creep, no 'while we're here' upsell.

Fully insured

£2M public liability and full insurance-grade reports on request for claims.

Health & safety first

Gas leaks treated as immediate priority, Gas Safe certified, CO incident trained.

One-visit resolution

Stocked vans mean most repairs (compression joints, push-fits, soldered copper, gas pipe sections) done same visit.

The Detail

What we'd tell a friend before they booked.

Leak repair sounds simple. The hard part is finding the leak, done badly, that means lifting every floorboard and knocking holes in every wall. Done properly, it means walking in with the right equipment and pinpointing the source before a single tile comes up.

Water leak detection methods we use

Acoustic detection, listening for the specific frequency of pressurised water escaping through a pinhole, even through tiles or concrete. Thermal imaging, hot or cold spots on walls, floors and ceilings caused by water tracking through structure.

Moisture meters, pinpoint mapping of moisture content in plaster and timber. Pressure testing, isolating sections of pipework and pressurising to identify the failed run.

Tracer gas, for very deep or buried leaks, an inert gas is introduced and tracked to the leak point with a sniffer. We use whichever combination is appropriate, most jobs only need acoustic and thermal.

Gas leak detection and immediate safety

Gas leaks are NEVER a 'tomorrow' job. If you smell gas: turn off at the meter (the lever sits perpendicular to the pipe when off), open windows and doors, leave the property, do not switch any electrics on or off, do not light anything, call the National Gas Emergency line on 0800 111 999 first.

They will attend rapidly, isolate the supply and make the property safe, they do not repair, so they'll then refer to a Gas Safe registered engineer. That's us.

We carry out a full gas tightness test, locate the leak, replace the failed section to current standards, re-test and re-certify the installation.

Common leak sources and what they cost to repair

Compression fittings under sinks loosen over time, typically £80–£150 to replace and remake. Push-fit fittings (Speedfit, Hep2O) can fail at the O-ring, £100–£180 swap.

Pinholes in copper pipework from years of slightly acidic water, repair £150–£280, full re-run if extensive. Failed radiator valves, £120–£200 per valve.

Boiler-side leaks (PRV, heat exchanger, expansion vessel) covered under our boiler repair service. Underfloor heating leaks need specialist detection and partial floor lifting, quoted on-site after thermal imaging.

Working with your insurance

Most home insurance policies cover the cost of leak detection ('trace and access') and the resulting repair to property damage, but not always the leak repair itself. We provide insurance-grade reports as standard, invoice, dated photos, detection method, repair description, and pressure test results, so your claim goes through cleanly.

We deal directly with loss adjusters on managed claims if it helps the process along.

FAQ

Leak Repair
questions, answered.

The questions we hear most from leak repair customers across East London and Essex, with straight answers from a Gas Safe engineer, not a marketing brochure.

How much does leak detection cost?+

Standard leak detection visit is £150 covering up to 90 minutes of detection work. If a leak is found and we proceed with the repair, the detection fee is credited against the repair cost.

How fast can you attend a suspected water leak?+

Same day in most cases, often within hours for emergencies causing active damage. Gas leak suspected? Call us immediately.

Do I need to lift floors before you arrive?+

No, we use non-invasive detection (acoustic, thermal, moisture mapping) specifically to find the leak before any damage is done.

Will my insurance cover this?+

Most home insurance policies cover leak trace and access plus consequential damage. We provide insurance-grade reports for your claim as standard.

Can you repair gas leaks?+

Yes, every Sound Gas engineer is Gas Safe registered and trained for gas pipework repair, full tightness testing and re-certification.

What if you can't find the leak?+

If after a thorough detection visit we can't locate it, you only pay the detection fee, and we'll recommend specialist next steps (e.g. CCTV drain survey for suspected drainage leaks).

Do you cover Waltham Abbey, Chingford, Loughton and Essex?+

Yes, leak detection and repair across our full service area as standard.

How long does a typical leak repair take?+

Detection: 30–90 minutes. Repair: 1–3 hours depending on access and the leak type. Most jobs are completed start-to-finish in a single visit.
