Pre-Lining Surveys

Cured-in-place-pipe lining requires accurate dimension and condition data to scope correctly. Our pre-lining surveys deliver pipe interior dimensions, defect locations, lateral tie-ins, ovality, and joint conditions — the data the lining contractor needs to size the liner, plan the lateral reinstatements and bid the work confidently. Engineering oversight and post-lining verification scans are also available.

Why Pipe Leak Detection for pre-lining surveys

Pipe Leak Detection is a sub-division of Leak.ca, the Greater Vancouver leak detection company trusted since 1999. Every site visit is delivered by certified technicians using calibrated equipment, with documented findings formatted for insurance, engineering and procurement use.

We don't sell remediation. Our role is independent detection and assessment — the data you and your professional team work from.

Pairs well with

Clients booking pre-lining surveys often combine it with In-Pipe Camera Inspection or Pipe Tracing & Mapping — particularly when the underlying issue spans multiple systems or when documentation needs to support a broader investigation.

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).
