As part of a reno, I paid to have some required insulation upgrades done. It was to be inspected with a follow up energy audit to allow a rebate. The work was not done suitably to meet the audit requirements. Had there not been an audit completed, I would have no idea that the work was done poorly. Also, a mess was left upstairs and in the garage. Disappointing as a consumer because I'm not auditing the quality of an insulation job. Apparently I should, because in the one and only case I've used GNI they have failed. They came to fix the problem with another crew and a supervisor to ensure it was done correctly. I work out of town, so I've had to adjust my schedule for a return visit by GNI and by the Energy audit group. GNI could only guarantee they'd be there between 1-3pm?? After they screwed up. In my mind GNI failed big time overall.
