Denise Martin

Owner and operator of BEO Ltd, Denise has been testing Houses in New Zealand since 2012. New Zealand is currently lacking in Building science,  theory and practice and Blower door testing is that practical application. The more we learn, and the more testing we do, the better our buildings will become. Follow Denise on social media for blower door testing videos, tips and success stories.
