Underground Leak Detection in Derry/Londonderry & Antrim
We use advanced methods such as tracer gas and acoustic technology to detect underground pipe leaks without having to dig up large areas. GPS mapping helps us trace pipe runs accurately, and thermal imaging identifies moisture and temperature differences in buried systems.
Internal Leak Detection in Derry/Londonderry & Antrim
Our team uses moisture mapping, thermal cameras and inspection cameras to locate the source quickly, avoiding the need to open up large areas unnecessarily. These techniques are ideal for identifying leaks from heating pipes, bathrooms, roofs, or internal plumbing.
Tracer Gas Leak Detection in Derry/Londonderry & Antrim
For smaller or more stubborn leaks, we use tracer gas - an advanced method that’s highly effective in detecting even the smallest escape. The gas is safe, non-toxic, and ideal for use in sealed systems where water loss is visible but the source isn’t.
Detailed Reporting & Insurance Support in Derry/Londonderry & Antrim
After detection, a full written assessment is provided. This includes location findings, cause, severity, and photographic evidence where applicable. The report is formatted to support insurance claims and is passed directly to our in-house loss assessor if required. Should the client choose to move forward with repair work, we can cover the cost of the leak detection upfront and manage the entire process through to full restoration.
