"Combi swap in a two-up two-down, needed the gas run upsized and boxed. KJ took the time to plan the route so it didn't dominate the kitchen. Great job."

Leak Detection in Accrington — Insurance-Friendly Report
In short
Accrington stone-terrace leaks are the same story as Blackburn and Burnley — lead soil-stack corrosion first, mains supply second, and thermal imaging distinguishes the two before any wall is opened.
Response: 85–125 minutes across BB5

£50 diagnostic — refunded if unlocatable
Insurer-accepted report format
Incoming water pressure across Accrington
Incoming mains typically 3.0–4.0 bar across BB5. Great Harwood elevated 2.6–3.4 bar.
Every report we send in Accrington prints the incoming static and dynamic pressure at the stopcock alongside the cause statement — pressure is often half the leak story and adjusters want to see it.
What leaks in Accrington actually look like
Accrington leak-trace work is dominated by stone-terrace lead-stack corrosion in BB5, push-fit joint failures on Great Harwood newer-estate mains, and concealed heating leaks in Oswaldtwistle semis.
Most common Accrington leak sources we see
- Lead soil-stack corrosion in BB5 stone terraces
- Push-fit joint failures on Great Harwood newer-estate mains
- Concealed heating leaks under Oswaldtwistle semi tile floors
- Failed shower waste seals in Accrington en-suites
- Central-heating pinhole corrosion in older BB5 rad circuits
What Accrington insurers actually want in the report
Common Accrington insurers: Admiral, Direct Line, Aviva. United Utilities is drainage authority.
Accrington insurers want a clear stack-vs-mains distinction on any pre-1960 stone-terrace claim — different repair specs, different exclusion clauses. Get it in the cause statement.
Every insurance-friendly report includes: date and address, incoming static and dynamic pressure readings (bar), thermal-imaging screenshots with location markers, acoustic-tracer transcript, dye-test results where applicable, non-invasive access method used, engineer name and qualification, and a plain-English cause statement. Delivered as a single PDF within 48 hours.
How KJ approaches a leak trace in Accrington
- For pre-1960 stone terraces, thermal-image the soil stack separately from supply pipework
- Log static AND dynamic pressure at the incoming stopcock
- Isolation-test the meter for 30 minutes before calling a supply-side leak
- For Great Harwood elevated stock, log pressure at multiple times of day
- Deliver the PDF report within 48h with stack-vs-mains distinction printed
Transparent Accrington leak-detection cost band
£185–£320 for a non-invasive trace and written report; £420–£680 with stone-terrace/lead-stack investigation.
Every price is confirmed in writing after the £50 diagnostic. Nothing beyond the trace itself starts without your approval, and the £50 is refunded if the leak can't be located non-invasively.
Why you shouldn't sign a Accrington rip-out quote before the report
An Accrington pattern is quoting a full mains replacement on damp that's actually lead-stack corrosion. Insist on thermal evidence first.
Our promise on every Accrington leak-detection call-out: £50 to attend, log pressure and run the first non-invasive trace; an insurance-friendly PDF report within 48 hours; and refund of the £50 if the leak can't be located non-invasively.
