ACEM Insulation Co. Ltd.

This is the best sub trade I have ever hired!
They arrived to do the quotation exactly as planned. A two person crew arrived exactly as planned. The set up was difficult because there are two attics and entry to one is over a staircase, which makes it about 20 feet above the stairs.
They were super careful with protecting corners, flooring, etc. ACEM did the work quickly yet carefully. They first installed stops between roof joists to ensure the air flow integrity of the soffits and then blew in the insulation. Cleanup was meticulous with vacuuming up any debris (I could not see any but this is their procedure). They were courteous throughout and took photos, a few of which I have included. I now have 20 inches of insulation in my attic, instead of 6 inches. Because they added 14 inches of spray foam to the existing insulation, the interface between existing and new insulation adds an extra resistance to heat/cold flow, ensuring lower bills both summer and winter. 30+ to -40 Celsius are both usual for St. Albert, Alberta for summer and winter respectively. This will save money, reducing our carbon footprint, increasing the value of our home and increasing our comfort. HIGHLY RECOMMENDED.
