About JEC
Independent building envelope consulting, from the field up
Jackson Envelope Consulting was founded by Spencer Jackson to close the gap between how buildings are drawn and how they hold up in wind and rain. We test the details that look fine on paper and give owners and project teams answers they can act on.

Spencer Jackson
Founder and principal consultant
Spencer has spent his career between design and field performance: plan review, failure analysis and hands-on diagnostics on active jobsites and in forensic investigations across the country.
He has seen the same pattern many times. A small oversight at a window transition or a rushed roofing detail turns into mold, remediation and sometimes a lawsuit. JEC exists to catch those details before the drywall goes up, and to find the real cause when they weren't.
He works as a third-party advocate for owners, developers, HOAs, contractors and architects, in residential and commercial buildings, using infrared thermography, ASTM E1105 spray testing and electronic leak detection.
JEC on LinkedInThe industry often settles for good enough. We push for built to last, starting at the interfaces and penetrations where buildings fail.
