It is hard to find good insulation companies, but after lots of research I finally found the best in GNI. Tremendous value and professional and courteous service with our attic insulation upgrade to R-52. They also weatherstripped and cribbed the hatch access door, foam air-sealed the ceiling fixtures and plumbing stack, installed 4 styrovents, installed fibreglass to clog the fireplace flue and did a great job with the blown-in cellulose. This was a great choice for attic insulation and I have felt the benefits this winter with much warmer house and gas bills cut significantly!
