Hello, My name is Lee Guajardo. My position here at Dura-Shield is an office manager. Our company has been using Insulation for less for three years now (prodex). We have been able to promise customers in our region at least 25 % off of heating and cooling cost. We have absolutely no complaints, just positive feed back. We have been members of the BBB for over 19 yrs now with an A+ rating. Thanks to Insulation for less, we can keep it that way.
