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.
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.
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.
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.
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.
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:
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.
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.
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.
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.
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.
