Very professional and diligent. Benjamin was very thorough when assessing the attic and made sure to explain every detail in regards to what the attic needs for proper insulation and air flow. Although there was some slight scheduling delay due to a worker having an injury the day before. They still completed the work in the planned timeframe. Honest, competent and fair prices. Highly recommend.

I had a fantastic experience with Isolation Thermo-Grenier. Benjamin, the owner, is honest, hardworking, and extremely thorough.

He provided a detailed estimate and clearly explained the entire process, which made me feel confident from the start. He didn’t just add insulation — he carefully sealed and repaired all the areas where heat was escaping. He also took before-and-after photos so I could see the work that was done.

On top of that, he helped me apply for the LogisVert program and secure the $1,500 reimbursement. His pricing was very competitive, and the quality of work was excellent.

I highly recommend Benjamin and his company!
