Sterling Gasfitting & Plumbing, leak detection is carried out using a systematic, evidence-based process designed to accurately locate concealed water leaks without unnecessary damage. We investigate issues such as unexplained high water bills, loss of pressure, damp areas, mould, and suspected hot water leaks using a combination of advanced testing methods. Depending on the situation, this may include shower testing, dye testing, and targeted isolation of fixtures to eliminate false positives. Pipework is pressure tested using nitrogen and hydrogen trace gas, allowing even the smallest leaks to be detected within walls, floors, and concrete slabs. We further confirm findings with professional acoustic listening equipment, pipe locating tools, and thermal imaging cameras to visualise temperature differentials caused by leaking water. This layered approach ensures the leak is pinpointed accurately, clearly explained, and supported by data — giving our clients certainty before any repairs are carried out.
