We had Hayes blow in insulation into our attic. They provided a few different quotes with different options for…complete removal and air sealing to just blowing insulation over the top. They were quick to answer our questions and did a good job following up with us. They were more expensive than a few other quotes we received, but they were also on time, followed up, and provided a higher quality of work than the other quotes I received. They blew insulation in our attic to get us up to R60, and we can already tell a difference in our house retaining cool air. We had an eight-degree variation between the main floor and the 2nd floor, I don’t know the current variation, but it isn’t noticeable when walking between floors.
