Courteous and knowledgeable technicians and sales people. On time for appointment. No damage to stored items in attic. Left attic in neat condition. Put 14” ﬂashing around hole in roof after installing exhaust fan. MLI on ﬂoored attic looked neat and complete to the edges. Cleaned out blown-in insulation that was obstructing air ﬂow at junction between rooﬂine and attic ﬂooring. Good job!
