About us

MAC-TECH was founded by Mr. Healy in 1989, 31 years ago. Already working in the field of security since 1975, he took to heart the well-being and security of businesses and citizens of his municipality and this is how MAC-TECH was born.

For the past few years, Mr. Healy had been thinking about retirement and wanted to pass the torch of his business. He set out to find a company whose owners espoused his values and whose attention to customer service was paramount.

… His patience paid off:

Serrurier Monteregie Inc., a dynamic company with people with experience in the locksmith and management field, has shown its interest in expanding their reach and having a foothold in Granby. Serrurier Monteregie Inc., as its name suggests, serves the Montérégie region but more particularly that of St-Hyacinthe and its surroundings. It has a large clientele at the institutional, industrial, commercial and residential levels.

MAC-TECH, which changes hands but no logo, will continue to serve you with the same care. The Serrurier Montérégie Inc team is there to share their expertise in order to provide solutions that will meet your needs.
