We hired GNI to top-up our main floor attic to an R60 with cellulose blow-in insulation. Right from the beginning it was a very professional and friendly experience. The sales rep, Michael, answered all my questions and went beyond my expectations by even agreeing to wrap my fan duct line with an insulation sleeve that I had purchased. They also installed some baffles to ensure proper ventilation and air circulation, rigid foam boards on the attic hatch and a hatch box wall. It only took about 4 hours for the guys to complete the work and they cleaned up nicely. Top notch company and highly recommend them!!
