Leak Analysis


Leak Detection and Analysis
ARC is highly skilled in the art of leak analysis and leak detection. We are a respected contractor serving San Francisco, Marin County and the greater Bay Area.
By relying on long experience and employing high pressure washing, we offer pinpoint detection of exterior building leakage.  If a leak persists, we have an array of tools and techniques -- including negative vacuum pressure, colored dyes, isolated area water testing and design analysis - that can be used to find the most difficult leaks. We provide detailed written reports with our findings, along with digital photos and product specifications, that will provide long term remedial relief.
