"No high pressure sales tactics. They said insulation could be repaired and with a mold treatment, did not need to be replaced."

"I like the product so far. It is insulation so I will not know the full effectiveness for awhile. Installation was fine.a little mess, but this a very messy product by nature. My biggest concerns were all related to customer service and communication. Promises to call me tomorrow really meant never. Sales side of the company and the install side did not coordinate effectively..so my install appt had to be rescheduled. When the e-billing came, there was nothing on the invoice allowing me to pay..no address, no phone#, No pay here button, etc. It was just clearly a company living in disorganization. Even the company truck had out of date license plates. I think the product will be good and the value is solid. Just be very clear in your communication expectations if you choose this company."
