Today certified solar heating and air conditioning was in the concord area performing a attic insulation blow in. We ensured that electrical was covered with can light covers, installed insulation rulers to ensure that we installed 22” in all areas that was possible. After blow in was completed we ensured that the platform was cleared and the home was spotless.
