Finding the source, not masking the smell
Fragrances and air fresheners solve nothing and only put the problem off. We trace it back to the cause:
- Trap water seal
- Faulty soil stack venting
- Leaking connection
- Crack in a sewer main
Our diagnostic methods
- Smoke test (smoke generator): shows where air, and the smell, is escaping
- CCTV drain inspection: spots cracks, faulty joints and traps
- Checking vents and water seals: verifies airflow and trap priming
- Dye tracing: confirms flow paths
