Leak Detection in Ealing
Edwardian villas in Ealing, leaking quietly behind plaster, give themselves away through stained ceilings, hidden damp, and unexplained Affinity Water bills, and we trace them across Acton, Hanwell, Greenford, and Southall using thermal imaging, acoustic, and tracer-gas methods, typically on site within 30 to 60 minutes.

Local insights
Leak detection in Ealing: the local picture.
Leak detection across Ealing covers W3, W5, W7, W13, UB1, UB2, UB5, UB6 and NW10, taking in Ealing, Acton, Hanwell, Greenford, Northolt, Southall, Park Royal and West Ealing. The borough's mix runs from Edwardian villas in Ealing through Victorian terraces in Acton and Hanwell to 1930s semis in Greenford and dense HMO stock in Southall. Affinity Water supplies hard, scale-heavy mains across the borough with a slightly different pressure profile to Thames Water territory.
HMO investigations across UB1, UB2 and Acton bring a particular brief: pressure-decay testing across isolated sections of multi-tenancy plumbing to find which flat or risers is bleeding water, hydrophone work on shared cold-water tanks in the loft, and the FLIR E96 thermal camera (640x480 sensor, less than 0.04 degrees C differential) reading heat trace through partition walls and ceiling voids. The Sewerin Aquaphon A150 acoustic kit (rod microphone on valves, ground microphone on screed) picks up underfloor and concrete-slab leaks across the converted-house stock.
Victorian terrace work in Acton and Hanwell leans on sodium fluorescein and Rhodamine WT dye under a Spectroline OPX-365 UV lamp, run through shower-tray wastes and bath traps to separate above-floor plumbing from waste-pipe failures on lath-and-plaster ceilings. For underground supply leaks running from the Affinity Water meter to the property (regular on Edwardian Ealing front gardens), the 5% hydrogen / 95% nitrogen tracer gas mix (BS EN 14338 compliant) is the standard tool.
Damp surveys in basement flats and ground-floor HMO conversions close with a Protimeter Surveymaster and Tramex pinless moisture map plus a salt-test analysis for nitrate, chloride or neutral salts (30 minutes on-site, 48-hour lab turnaround). Insurance-grade trace-and-access reports are written in the format accepted by LV, Aviva, Direct Line, Admiral, Hiscox, Zurich, AXA, RSA, NIG, Allianz, Ageas and Legal & General. Survey from a fixed starting fee, repair work at the inner-London half-hour rate.
