Local coverage
Brockley sits in a conservation area, and when a stain spreads across a Lewisham ceiling our directly-employed engineers typically reach you within 30 to 60 minutes, tracing hidden leaks behind the ageing copper of Forest Hill and Sydenham with thermal imaging, acoustic and tracer-gas methods rather than tearing the property apart.

Local insights
Leak detection across Lewisham covers SE4, SE6, SE8, SE12, SE13, SE14, SE23 and SE26, taking in Lewisham, Catford, New Cross, Forest Hill, Sydenham, Brockley, Hither Green and Honor Oak. Victorian terraces in Brockley and Forest Hill, Edwardian villas in Honor Oak, and post-war estates in Lewisham and Catford all draw from a moderate Thames Water supply. Brockley conservation area, plus Forest Hill and Sydenham Edwardian stock with original copper now ageing, sets the borough's leak-detection pattern.
Brockley conservation work begins with a Protimeter Surveymaster and Tramex pinless moisture map to fix the wet boundary, then the FLIR E96 thermal camera (640x480 sensor, less than 0.04 degrees C differential) traces heating-circuit flow under solid floors and inside ornate cornice work. Pressure-decay testing across isolated sections of the central-heating primary circuit narrows the failure before any original board is lifted.
Forest Hill and Sydenham Edwardian-villa work is dominated by pinhole leaks on original copper. The Sewerin Aquaphon A150 acoustic kit (rod microphone on valves, ground microphone on screed) picks up underfloor leaks on solid-floor kitchens and dining rooms. Hydrophone work on loft cold-water tanks confirms whether the source is a vessel or pipework leak. Sodium fluorescein and Rhodamine WT under a Spectroline OPX-365 UV lamp separates above-floor plumbing from waste-pipe failures on shower trays.
For underground supply leaks running from the Thames Water meter to the front door across Hither Green and Honor Oak, the 5% hydrogen / 95% nitrogen tracer gas mix (BS EN 14338 compliant) is the standard tool. Damp surveys in basement and lower-ground flats close with a salt-test analysis (30 minutes on-site, 48-hour lab turnaround) for nitrate, chloride or neutral salts. Every investigation generates an insurance-grade trace-and-access report accepted by LV, Aviva, Direct Line, Admiral, Hiscox, Zurich, AXA, RSA, NIG, Allianz, Ageas and Legal & General. Survey and any follow-on repair are billed at our flat half-hour labour rate for the time of day, with no callout fee.
