WETT-certified professionals must abide by a code of ethics requiring professionalism in all aspects of their work. The installation and maintenance of wood-burning appliances is not regulated in Canada. As a non-profit training and educational association, WETT does not oversee, nor is it responsible for, the workmanship of its members. As such, WETT does not act as a regulator. WETT does maintain internal processes to address breaches of our code of ethics, however WETT cannot become involved in resolving consumer disputes.WETT trains and certifies individuals, not companies. Companies can use the WETT logo if someone at their company is WETT certified, but only those who have been issued certification by WETT can claim to be WETT-certified. WETT-certified professionals carry photo ID cards. Ask to see an ID card and ensure that it carries a valid sticker showing the current year.
