If you've noticed an unexplained increase in your water bill, damp patches appearing around your property, reduced water pressure, or water pooling where it shouldn't be, you may have a hidden leak.
At Downham Drainage Services, we provide professional leak detection services across Norfolk, helping homeowners, landlords, businesses and agricultural properties locate hidden water leaks quickly and accurately. As an member of the National Association
of Drainage Contractors, we have the experience and specialist equipment needed to identify leaks with minimal disruption and help prevent costly damage.

What Is Leak Detection?
Leak detection is the process of locating hidden water leaks within underground pipework, drainage systems, water supply pipes, and external services without the need for extensive excavation.
Many leaks occur underground or behind walls where they cannot be seen. By using specialist technology, our engineers can pinpoint the source of a leak quickly, reducing the need for unnecessary digging and repairs.
Signs You May Have a Hidden Water Leak
Many property owners don't realise they have a leak until significant damage has already occurred.
Common warning signs include:
Unexpectedly high water bills
Damp patches on walls, floors or ceilings
Low water pressure
Waterlogged areas in gardens or driveways
Cracks appearing in paving or hardstanding
Constant sounds of running water
Mould or mildew growth
Warm spots on floors where pipes may be leaking
If you've noticed any of these issues, arranging professional leak detection could help prevent further damage.

Why Leak Detection Saves Money
Many people delay investigating a suspected leak because they assume it will be expensive.
In reality, finding a leak early is often far cheaper than dealing with the consequences.
Lower Water Bills
A small leak can waste thousands of litres of water every year. Even a minor leak in an underground supply pipe can significantly increase your water costs over time.
Prevent Property Damage
Water leaks can cause:
Structural damage
Damp and mould growth
Damage to flooring and decorations
Foundation movement
Damage to driveways and landscaping
The longer a leak goes undetected, the greater the repair costs can become.
Avoid Emergency Repairs
Emergency excavation and repairs are often far more expensive than planned maintenance. Early detection allows problems to be resolved before they become urgent.
Reduce Business Disruption
For commercial premises, a hidden leak can lead to downtime, operational issues and expensive repairs. Detecting leaks early helps keep businesses running smoothly.
How We Find Hidden Leaks
At Downham Drainage Services, we use a range of specialist leak detection methods depending on the type and location of the suspected leak.
These may include:
Tracing and Location Equipment
We can accurately trace underground pipework and identify problem areas before excavation takes place.
CCTV Drain Surveys
Our high-definition drain cameras allow us to inspect drainage systems internally to identify damage, cracks, displaced joints and leaks.
Pressure Testing
Pressure testing helps determine whether a water supply system is losing water and identifies potential leak locations.
This targeted approach reduces disruption and helps avoid unnecessary digging.
