Pre-Demolition Scans

Pre-demolition scanning is the low-cost insurance against very expensive demo-day surprises: hidden conduit, post-tension cables, active pipes, asbestos in unexpected places, structural framing not on the drawings. We deliver pre-demolition scans for general contractors, demolition contractors and tenant-improvement teams. The output is a marked-up site plan showing what's hiding behind, beneath or above the planned cut.

Why Leak Scanning for pre-demolition scans

Leak Scanning 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-demolition scans often combine it with Multi-Sensor Surveys or Flow & Pressure Diagnostics — 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).
