Drain surveying and CCTV inspections
Persistent drainage problems, suspected defects or an unclear drain route may call for a survey. A survey can help locate defects in accessible drainage and inform a proportionate repair plan.

We investigate before recommending where to open up. Our aim is to use the evidence to keep any necessary access targeted.
What to watch for
Signs You May Have a Hidden Water Leak
You do not need to see running water to suspect a leak. Common warning signs include:
- A water bill rising without a change in usage
- Damp patches, peeling paint, mould or musty smells
- A boiler or heating system losing pressure repeatedly
- A water meter moving when taps and appliances are off
- Warm spots in floors or unexplained sounds of running water
- Persistently wet ground or unusually lush patches of grass
These symptoms can have more than one cause. The right investigation helps identify where the moisture or water loss is coming from.
Where we investigate
Leak Detection and Property Services in Surrey
A hidden pipe leak in Guildford, repeated drainage symptoms near Woking or a roof stain in Reigate calls for evidence suited to the building. We select investigative methods to suit the symptoms and property, then explain the findings and practical next steps.
- Cold and hot mains water supply pipes
- Central heating and boiler pressure loss
- Underfloor heating and concealed pipework
- Water ingress and flat roof leaks
- CCTV drain surveys and drainage investigations
- Pipework mapping, moisture checks and drying assessments
For hidden leaks in supply pipes, heating systems, floors or walls, we can use moisture readings, acoustic equipment, thermal imaging and tracer gas as appropriate. Testing is chosen around the pipe material, pressure and construction so that any proposed access is guided by the evidence. Investigations can be trace only or include access where suitable. Explore our leak detection service.
Our approach
How We Investigate a Concealed Water Leak
Different pipe materials, building layouts and symptoms call for different tests. We choose methods to suit the property.
Acoustic detection
Uses specialist listening equipment to identify possible sounds of water escaping under pressure.
Thermal imaging
Looks for temperature differences that may help trace hot pipework or water-affected areas.
Moisture checks
Measures and compares moisture patterns in affected building materials.
Tracer gas testing
Uses a suitable tracer gas method where a leak is small or difficult to locate by other means.
Over 20 years' combined experience
Our team brings experience in construction, plumbing and maintenance to interpreting the results. We aim to locate the problem before recommending targeted access or repairs.
Flexible investigations
Trace Only or Trace and Access
The scope depends on the system, access and what is agreed before work begins.
Some home insurance policies include trace and access cover. Check with your insurer before booking, as cover and evidence requirements vary. We can discuss reporting and documentation for your investigation.
Beyond a hidden pipe leak
Other Property Investigations in Surrey
Finding the right cause matters. These additional investigations can help with drainage, roofs and moisture left after a leak.
Flat roof leak investigation
Water appearing beneath a flat roof does not always enter directly above the visible stain. Flat roof investigations consider outlets and junctions as well as the position of internal staining.
Pipework mapping
When the route of concealed water or heating pipework is uncertain, mapping can help identify likely pipe runs before drilling or opening a surface. Tracing likely pipe runs can help before drilling into a floor or opening finishes to reach a suspected leak. The achievable detail depends on the pipe material and construction.
Drying and restoration
After the source of a leak is addressed, affected materials may still hold moisture. Checking moisture beneath visible surfaces helps decide whether controlled drying is needed before restoration.

Leak Detection in Surrey: FAQs
Find answers to common questions, or contact our team about your property.
-
How do I know if I have a hidden water leak?
Warning signs include an unexplained higher water bill, damp or mould, a boiler that keeps losing pressure, or a water meter moving when taps are off. These signs can have other causes, so an investigation helps establish the source.
-
Will you need to dig up my floors or garden?
We aim to narrow down the leak using suitable non-invasive tests first. If opening-up work is needed, we explain where and why before access is arranged.
-
What is the difference between trace only and trace and access?
Trace only investigates and reports the suspected leak location. Trace and access can also include opening the relevant area to reach the pipework, where appropriate and agreed.
-
Will my insurance pay for leak detection?
Some policies include trace and access cover, but the conditions vary. Check your policy wording and speak to your insurer before authorising work.
-
How long does a leak survey take?
It depends on the property, pipework and symptoms. We can discuss the likely scope and timing when you enquire.
-
Do you investigate commercial properties as well as homes?
Yes. We can discuss investigations for homes, rented properties and business premises, subject to the requirements of the site.
