Our Leak Detection Services

We offer a comprehensive range of leak detection services to locate leaks anywhere in your Welwyn Garden City property — behind walls, beneath floors, underground, within your heating system. Our multi-method approach means we find the actual source of the problem, not just where the water ends up.

Water Leak Detection

We locate hidden leaks in mains supply pipes, internal plumbing and waste systems using expert water leak detection services that pinpoint the exact leak location.

Central Heating Leak Detection

We find leaks in radiator pipework, boiler connections and sealed heating systems with our dedicated central heating leak investigation. Ideal when your boiler keeps losing pressure.

Underfloor Heating Leak Detection

We trace leaks in underfloor heating circuits beneath screed, tile and laminate floors using specialist underfloor heating leak surveys.

Underground Leak Detection

We locate leaks in buried supply pipes, service pipes and drainage systems across gardens and driveways with underground pipe leak detection methods.

Commercial Leak Detection

Full commercial property leak detection and repair for offices, retail, hospitality, healthcare and industrial premises across Welwyn Garden City.

Trace and Access

Insurance-approved trace and access leak investigation services with detailed reports, photographic evidence and findings to support your claim.

Leak Detection Technology We Use

Finding a hidden leak takes more than guesswork. Our leak detection engineers use multiple non-destructive testing technologies, choosing the most appropriate methods based on your property type and the suspected leak location. This multi-method approach gives us the best chance of pinpointing the leak while keeping disruption to a minimum.

1

Thermal Imaging

Our thermal imaging camera surveys use infrared technology to detect temperature differences caused by escaping water. Ideal for locating leaks behind walls and beneath floors without damage.

2

Acoustic Listening

Acoustic leak detection technology uses sensitive microphones to detect the sound of water escaping under pressure. Excellent for tracing leaks in mains supply pipes and buried pipework.

3

Tracer Gas Detection

For heating systems and underfloor circuits, tracer gas testing introduces a safe gas that escapes at the leak point and rises to the surface for detection.

4

Moisture Mapping

We use advanced moisture meters and mapping to track dampness through building materials, helping trace the leak path back to its source with precision.

Leak Detection for Welwyn Garden City Property Types

Welwyn Garden City's distinctive housing stock presents unique challenges for leak detection. As one of the UK's original planned garden cities, the town has a particularly varied mix of property ages and construction styles — each with different pipe materials, layouts and common leak points.

Original Garden City Properties

The 1920s and 1930s homes that form the heart of Welwyn Garden City — around Handside, Peartree and the town centre — were built with the distinctive Arts and Crafts character the garden city is known for. These properties typically have a mix of original and updated plumbing, with leaks commonly occurring at joints between different pipe materials. Our thermal imaging and moisture mapping can trace these complex pipe runs without opening up the structure.

Post-War and Modern Developments

Areas such as Panshanger, Woodhall and Hall Grove include a mix of post-war housing and more recent developments. While newer plastic pipework is less prone to corrosion, leaks still occur at joints, manifolds and connections. Many modern properties also have underfloor heating, which requires specialist detection when a leak develops in the circuit.

Commercial and Industrial Properties

Welwyn Garden City has a significant commercial presence, including business parks, retail units in the Howard Centre and industrial premises. We provide professional plumbing leak investigation and repair for commercial premises with flexible scheduling to minimise business disruption.

Signs You Might Have a Leak

Many leaks stay hidden for weeks or months before becoming obvious. By the time you see visible damage, significant water may already have been lost. If you've noticed any of these warning signs, our leak detection services can help — you can also use our quick leak checker tool to assess your situation.

Water bill has increased unexpectedly
Damp patches on walls or ceilings
Musty or mouldy smell
Sound of running water when off
Warm or wet spots on floors
Low water pressure throughout

Catching a leak early typically means simpler repairs, lower costs and less disruption to your home or business.

How Our Leak Detection Process Works

When you contact us about a suspected leak, here's what happens:

1

Initial Conversation

We discuss your situation over the phone. What have you noticed, where, and when? This helps us understand what kind of leak we're likely dealing with and which equipment to bring.

2

Site Survey

Our engineer inspects your property, looks at the visible damage, checks systems (boiler pressure, water meter, etc.) and identifies access points. We explain our approach before starting.

3

Detection Work

Using thermal imaging, acoustic listening, tracer gas, moisture mapping or a combination, we systematically trace the pipe runs and isolate the leak source. This usually takes 1–4 hours for domestic properties and 2–6 hours for commercial premises.

4

Findings and Report

Once we've located the leak, we explain what we've found, show you the evidence and mark the leak location. You'll receive a written report with photographs, suitable for insurers.

5

Repair Guidance

We advise on repair options and can carry out minor repairs same day. For larger jobs, we provide clear information and a quote, or you can choose your preferred contractor.

Think You Have a Leak?

Don't let water damage get worse. Our engineers can locate your leak quickly using non-invasive technology.

Insurance Claims & Trace and Access

If you're claiming on your home insurance for water damage, your policy may include trace and access cover. This typically pays for the trace and access survey to find where the leak is coming from, separate from the cost of repairs.

Not sure whether your policy includes cover? Check your policy documents or contact your insurer before arranging your visit.

Our Reports Include:

  • Description of investigation methods used
  • Photographic and thermal imaging evidence
  • Precise leak location with property layout
  • Technical findings and pipe identification
  • Recommendations for repair

Frequently Asked Questions

How quickly can you attend a leak in Welwyn Garden City?
In most cases we can arrange a leak detection visit in Welwyn Garden City within 24–48 hours, and often sooner for urgent issues. For customers in AL7 and AL8 postcodes and nearby areas such as Hatfield, Welwyn and Hertford, we're able to offer same-day or next-day appointments depending on our schedule.
What types of leaks can you detect?
We specialise in locating hidden leaks that are difficult to trace without specialist equipment. This includes mains water supply pipe leaks, internal plumbing and waste pipes, central heating and radiator circuits, underfloor heating systems and underground leaks in gardens, driveways and yards.
Will you need to damage my floors or walls to find the leak?
Our aim is always to minimise disruption. In most cases we can locate the leak using non-invasive methods such as thermal imaging cameras, acoustic microphones, tracer gas and moisture meters. This allows us to trace pipe routes and identify the leak location without lifting floors or breaking into walls unnecessarily.
Can you help with insurance trace and access claims?
Yes. Many Welwyn Garden City customers contact us because their home insurance includes trace and access cover. We provide detailed written reports with photographs, equipment used and clear findings, which are designed to support insurance claims.
Do you carry out repairs as well as leak detection?
Our primary focus is professional leak detection, but in many cases we can carry out minor repairs at the same visit, such as fixing accessible pipe joints or small sections of pipework. Where more extensive work is required, we'll clearly explain the options, provide a quote where appropriate, or supply the information your chosen plumber or builder needs.
