The Insulation Guru came out and did an excellent job on insulating my 1977 house. the team showed up early on a Saturday morning and worked HARD on prepping the attic, even in the summer heat. I had done a lot of research and found out that the fly by night guys just come in a ‘blow and go” and never prep the area. They cleared all the covered soffetts, filled all the holes, insulated all the can lights and placed baffles by the soffetts. They spent nearly 4 hours just prepping the area and then afterwards finally blew in the pink insulation. I had a small problem where they had accidentally hit a switch in the attic, which wasn’t noticed on final inspection so the owner himself came out on a Saturday night and remedied the issue. I would highly recommend them.
