Mr. Charron has served the Canadian Military both as a military and as a civilian. He graduated from the Royal Military College of Canada (RMC) and also retired from the military in 1992. As a military, Mr. Charron was, among other things, part of a group investigating the environmental condition of CFB Lahr in Germany before the Canadian government was to return the land to Germany. Following his military years, Mr. Charron continued to serve the Canadian Forces as a civilian doing research in the structural engineering laboratory at RMC. During those years, he was published numerous times both as an author and a co-author in engineering publications such as The Canadian Journal of Civil Engineering. Following his findings in a research project, he was instrumental in having part of the Canadian Wood Design manual changed to better reflect the compressive properties of wood in construction.

As a member of Property Inspection Network, Ltd, Mr. Charron is a building science expert and specializes in “Pre-purchase home inspections”, “Infrared Thermography”, “Flat Roof Investigations”, “Engineering Assesments” and “Home energy audits”. Mr. Charron has now completed over 7000 inspections, infrared investigations, engineering assesments and energy audits in Eastern Ontario and Western Quebec assessing structures, mechanical systems, insulation, interior and exterior finishes, roofing, chimneys, and building envelope.

Mr. Charron has presented the findings of a thermography investigation done for a large condominium corporation at the 2012 annual InfraMation conference in Orlando. His work on that project allowed the corporation with a limited budget to prioritize its roof replacement schedule and meet its obligations to the unit owners.

The infrared camera used by Mr. Charron during his thermography investigations is a FLIR B-250.

  • Natural Resources Canada Energy Auditor


Member of Property Inspection Network Limited. Previously general contractor involved in residential construction and renovations. Work for various insurance companies focused on assessment of replacement value and liability analysis. Inspections focus on assessing the structure as a whole system, roofing, chimneys, electrical and mechanical systems, insulation, exterior/interior finishes, and the general building envelope. Elements also considered are radon gas, indoor air quality, energy efficiency and electromagnetic fields.

WETT inspections focus on the safety of the wood burning system (fireplace or wood appliance and chimney) installation. Many insurance companies require a WETT certified inspection report.

Infrared inspections can detect missing insulation, moisture infiltration, air leaks, and more. Roof inspections for flat roofs can identify specific locations that need repair without entire roof replacement.

Other experience includes project management, quality control, customer service, training, documentation, and requirements definition. In our community, Ted’s experience also includes president of cottage association, treasurer/member of board of directors for hockey association, and various roles as coach and/or official in minor hockey and baseball.

Mr. Mathisen graduated from Queens University’s civil engineering program in 1987 and has been licensed in the province of Ontario as a professional engineer since 1994.

Following university, Mr. Mathisen worked as a junior civil engineer with several municipal engineering and environmental consulting firms, gaining broad exposure to municipal projects including roads, small bridges, water supply and sewer systems, surface water management, hydrogeology and environmental impact screening. Work usually involved engineering design aspects as well as field supervision of construction activities.

Mr. Mathisen then became involved in international development, working for many years in multi-year postings in Nicaragua and Ghana, as a water supply and sanitation engineer, and manager of projects providing community water supplies and sanitation services, primarily in Latin America, Africa, Asia and the Middle East, and including several periods living overseas. 

Since 2005, Mr. Mathisen has focussed on the residential sector. From 2005 to 2012, he worked as a home designer and construction manager, working with a builder to develop custom country homes for individual clients in the national capital region. He was also contracted by Natural Resources Canada’s Local Energy Efficiency Partnership project (LEEP), which works with Canadian homebuilders to promote energy-efficient /renewable technologies in home construction. There, he designed and developed a cost database of innovative home technologies which was then rolled out nationally, to assist developers and builders across Canada to assess design and pricing options using the capital costs and cost-recovery periods provided in the database.

Since joining Property Inspection Network, Stein has focussed on the delivery of quality home inspection services for Ottawa’s real estate market, offering personal, trustworthy assessments of homes to home buyers, sellers, developers and real estate agents.
