ASTM E1105 and AAMA water-spray investigations.
Window and curtain-wall water-penetration testing follows ASTM E1105 and AAMA standards: controlled water spray at calibrated pressure differential, with observers inside watching for ingress. We supervise these tests on commercial and institutional facades — for new-construction acceptance, for post-installation troubleshooting, and for leak investigation on existing buildings. The deliverable is a witnessed report with time-pressure data and a clear acceptance or failure finding.
Patio Leak 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.

Per spec — typically no controlled leakage during the test period.
