"The GIC team was very prompt and knowledgeable. They were very neat and cleaned up well after themselves. We had our attic insulated and foam sprayed on rim joist and basement crawlspace. We noticed the house to be much quieter immediately. So glad we had this done in January before the -22 degree temperatures hit. Can't wait to see the effect on summer air conditioning bills."

"My experience with Victory Insulation went extremely well. They installed blown fiberglass insulation in my attic. The installation crew was very helpful and easy to work with. Since the install, my family has already noticed our hvac running a lot less within the last few months. I highly recommend working with Victory."
