About Mario's Windows and Doors

Mario immigrated from Austria in 1992 and in the same year started an apprenticeship as a licensed carpenter in the window/door and renovation industry. After several years as a journeyman in this field, Mario started the business in Barrie in Year 2000, approaching the business in the fashion of no compromises on quality. We believe in good-old-fashioned family values and you will find those in our working relationship as well – committed to your satisfaction. Today more than 85% of our business is repeat and referral customer (we love referrals!)
