Sewer Leak Detection

When CCTV shows a suspect defect but it's unclear whether the line is exfiltrating, tracer-gas and dye-testing methods confirm leakage. We pressurize the line with non-toxic tracer gas or run dye through the system and locate the escape point on the surface. This is the methodology for confirming sewer-leak insurance claims and for satisfying engineering questions about specific defects.

How to prepare for your visit

1. Document what you're seeing. Photos, dates, sounds, water-bill changes, anything unusual. The more we know in advance, the faster we can locate.
2. Clear access to the suspected area. Move furniture, stored items, and rugs. Non-invasive methods still need clear sightlines.
3. Have system history ready. Recent plumbing work, prior leaks, renovations, age of property, prior insurance claims.
4. Confirm the email for your report. Photo-linked report delivered within 48 hours (often same-day for residential).
