Odour Diagnosis Is About Method, Not Guesswork
Most drainage smells come from one of four causes: dried-out traps, blocked vent stacks, grease coating in waste pipes, or fractured pipes leaking sewer gas through walls/floors. Each looks similar from the outside — but each needs a different repair.
We use methodical diagnosis: CCTV the lines, smoke test the system, pressure test if needed. The investigation finds the actual source — not just somewhere that smells. Then we quote a permanent repair.

Common Odour Sources We Find
Dried Traps
Sink, washer or floor trap dried out — sewer gas escapes back up.
Blocked Vent Stacks
Roof vent blocked — drains can't breathe, gas escapes inside.
Grease In Pipes
Old grease coating waste pipes, decomposing.
Cracked / Failed Pipes
Sewer gas escaping through damaged pipework.
