"We called Mister Insulation and Jeff came out in a day or so. We explained that we purchased new windows and doors and had insulation blowen into the walls but the house was still not warm. He took pictures in the attic and used a thermal camera to show where we were losing heat also we had mold. He removed the mold and replaced the insulation . He and his crew were very professional. We would recommend them ."

"There was a problem initially with the radiant barrier installation - the first crew of two were installing 30" wide rolls lengthwise along the roof end to end instead of from ridge to eave as the manufacturer recommends and made a couple of other minor mistakes which were easily corrected. After talking to the manufacturer, the sales rep offered to take out what had been installed and re-install according to spec or continue as already done with sealing of all seams and a discount on the job. Done this way, the foil would not have the insulation properties per spec but would provide the radiant barrier I desired. I chose the letter option and the barrier work was continued by another crew on the 2nd day. On the 3rd day the crew finished up with the barrier then blew in the installation.
With the exception of the initial problem, the work was done neatly and professionally by courteous workmen who cleaned up completely after the job was done.
