What makes us stand apart?

The principals of TMI® have been involved in the construction industry since 1982 as land developers, as builders of residential and commercial properties, and as early adapters of air barrier materials and methods. Our past experience comes from hands-on construction project management, as principals. We have walked the walk. From design drawings and specifications, through contract documents, subcontracted trades-coordination and sequencing, inspections, punch out and completion on-time on-budget, with little to no warranty issues. We have lived and understand the process better than those who have merely sat in classes or behind a desk.

In 2007 TMI® was formed to assist building owners reduce energy costs, consumption, and sustain the life of buildings. What started out as an infrared inspection firm specializing in diagnosing moisture and air infiltration quickly grew into a building enclosure and consulting firm. Our years of experience, knowledge and understanding of the construction process, trades, air barrier materials, and thermal and moisture protection sets us apart from our competitors.

TMI® Building Enclosure Specialists are expert in building enclosure air barrier systems. We possess the experience and technical building science knowledge of design, performance, systems and construction relative to the building enclosure and are recognized leaders in their field of expertise.

We approach every project as if it were our own. We analyze established best practices to ensure a successful outcome of an airtight enclosure for the general contractor and owner. Our principals stay with you every step of the way, and guide you through the process.

Our track record for approved federal submittals on the first go-around is 100%.
