Zenic insulation came on September 2011.
They prefer to pass the injection hose through the window(s) to get to the attic hatch, rather than through entry of front or side doors. Upon inspection, no addition vent baffles were needed. Estimate was very simple, so much a square foot (< $1.00 for me), for the thickness you need. Just measure how much insulation you have now (i.e. 4", 6", 8", ...) and they will tell you the price per square foot over the phone to get to the level you want (R50).
They laid down the front runners (blankets) to protect the floor, plastic sheet around the attic hatch, and added enough dry cellulose (loose fill) insulation to get the R-50 (total was 22 inches in my case, which allow 2” for settling) to my attic.
Once done they added a gasket along the perimeter of the attic hatch and also insulation (in a bag). They did a quick cleanup afterwards.
