Client Testimonials

I would like to congratulate you on prioritizing me for an emergency repair on my crooked roof. You were very understanding of my situation. My contractor is Mr. Patrice Beaupré.

This morning, I would also like to add my comments to Mr. Kevin Bergeron and Ian Beauchamps for their punctuality. Both were very friendly despite the slippery weather, and they remained calm. I am very satisfied with their work, their speed, and their professionalism. Thank you from the bottom of my heart. Another satisfied customer. See you soon!

I hired Isolation Majeau et Frère to blow cellulose in our attic, and they delivered at every step -from sales through planning to installation. Ian and Gaétan showed up on time and followed the plan without fuss. True pros: meticulous, efficient, and they achieved R-60 evenly across the whole attic. Couldn’t be happier - thanks for a job well done!

I obtained several quotes, and Isolation Majeau was by far the most competent and affordable company I dealt with. Normand and Geoffroy came to my home. They accommodated my specific requests and did an extremely professional job. I highly recommend them. A+++ service
