Mission
At The Building Science Detectives, we apply advanced building science and data-driven diagnostics to uncover the true causes of building performance issues. Our investigations and consulting services equip property owners and builders with clear guidance to design, construct, maintain, and repair buildings that are safe, efficient, durable, and resilient. By solving problems at their source, we help clients make informed decisions that protect their investments and support long-term building health.

Vision
We aim to advance how homes and buildings are understood, maintained, and managed by integrating expert diagnostics with proactive, technology-supported solutions. Our work moves the industry toward a future where property owners benefit from predictive insights, simplified maintenance, and continuous performance improvement. Through innovation, accessibility, and a commitment to building longevity, we strive to create a built environment where every structure operates reliably and every occupant experiences comfort and confidence.

Jonathan built The Building Science Detectives around a simple idea. Buildings behave like living systems and they deserve to be understood that way. His background blends building science, energy performance, sustainability work at Biltmore, and a lifelong curiosity about how things function. That mix turned a personal obsession into a career focused on diagnosing comfort issues, moisture problems, efficiency gaps and the hidden interactions that shape how a building performs.

Clients come to Jonathan when guesswork will not cut it. He uses advanced diagnostics, clear analysis and a practical understanding of construction to explain why a problem exists and how to fix it with confidence. His work is grounded in data but delivered with the belief that every building can work better.

Away from inspections and consulting, Jonathan is usually found working on projects at home with his family. It is the perfect testing ground for new ideas and occasionally a reminder that even experts discover surprises behind walls.
