"Oil boiler running rough all winter. KJ came out on the OFTEC ticket, changed the nozzle and rebalanced the burner properly. First time it's worked cleanly in years."

Leak Detection in Oldham — Insurance-Friendly Report
In short
Saddleworth (OL3) leak calls often start as "damp in the corner" and turn out to be a combined-sewer surcharge misdiagnosed for months — the trace has to rule out drainage before it rules in supply.
Response: 50–85 minutes across OL1–OL9

£50 diagnostic — refunded if unlocatable
Insurer-accepted report format
Incoming water pressure across Oldham
Incoming mains typically 3.4–4.4 bar across OL1–OL9. Saddleworth hillside properties (OL3) frequently see 2.6–3.4 bar due to elevation.
Every report we send in Oldham 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 Oldham actually look like
Oldham leak-trace work is a mix of push-fit joint failures on Failsworth/Chadderton semis, 100-year-old lead-solder failures in central Oldham terraces, and Saddleworth combined-sewer confusion where the "leak" turns out to be sewer surcharge.
Most common Oldham leak sources we see
- Push-fit joint failures on Failsworth/Chadderton semi mains
- Lead-solder failure on cold mains under central Oldham terraces
- Combined-sewer surcharge (misdiagnosed as leak) in OL3 after heavy rain
- Concealed heating leaks under Royton semi tile floors
- Failed shower waste seals in Saddleworth cottage en-suites
What Oldham insurers actually want in the report
Common Oldham insurers: Direct Line, Admiral, Aviva. Direct Line adjusters ask for the isolation-test result alongside the thermal image.
Oldham insurers (particularly Direct Line) want the isolation-test result printed on the report — a 30-minute meter hold with all fixtures off, either "no movement" (leak is heating-side) or "visible movement" (leak is supply-side). That single test halves the loss-adjuster's questions.
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 Oldham
- For OL3, rule out combined-sewer surcharge before diagnosing a supply leak
- Log static AND dynamic pressure — Saddleworth hillside can be misleadingly low
- Isolation-test the incoming mains for 30 minutes before calling a supply-side leak
- Thermal-image the leak area AND the floor/wall below with permission
- Deliver the PDF report within 48h with the isolation-test result printed
Transparent Oldham leak-detection cost band
£185–£320 for a non-invasive trace and written report; £420–£680 with combined-sewer floor 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 Oldham rip-out quote before the report
A recurring OL3 pattern is quoting a supply-side repair on damp that's actually combined-sewer surcharge after heavy rain. Insist on ruling out drainage before any supply-side repair is authorised.
Our promise on every Oldham 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.
