"Thermal Home Insulation did blown in insulation, air sealing, and radiant barrier work in my attic. The initial estimate took place quickly after my inquiry, and was very informative. Jim was able to get the job scheduled within 1 week as well, and was able to help me take advantage of a material discount and home energy efficiency program discount as well. The house already does a better job of retaining heat and cold. Thank you for the good work in a very timely manner, and for answering my questions along the way and being flexible. Would recommend to anyone with high energy bills due to their attic space temperature balance."
