Looking over the reviews here, I'm not sure I can add much. But like blown-in insulation, a little more is always good. So let me echo all the positive sentiments below: Kent was kind, courteous, helpful, and easy to speak to on the phone. (Only advice would be to also make email a priority; I almost gave up on the company because it's difficult for me to get a call out during normal business hours, and I never did receive an email reply...)
The quoted price is more than fair for the quality of material and workmanship. Kyle and Gary were on time (with a courtesy call beforehand), professional, and cleaned up after themselves. I appreciated the little extras like an obvious effort on Kyle's part to make sure the front door wasn't wide open when the hose was passing through as well as being offered the opportunity to poke my head into the attic to see the job.
We are very happy!
