If you are looking for a company that couples outstanding work with outstanding customer service, then Green Attic Insulation is who you should definitely call. I truly wish I would have called them years ago as I have been putting off suspected issues that centered around extreme temperature fluctuations between winter and summer, along with poor ventilation, within my attic. From the time that Tim arrived for assessment after great communication from Alina, to the installation of the insulation and solar fan with Charlie and his team, to a final blower door test, every aspect was performed professionally and as outlined by the quote. The issues identified were explained thoroughly, with the after result reviewed with me to ensure it was completed as expected. The company must take pride in the people they hire because it showed with their skill and personalities. They were great to be around that day. As for pricing, I originally expected the final quote to be much higher, but found the quote to be very fair and reasonable. So again, if you are looking for quality on a job done right, I definitely recommend that you call Green Attic Insulation. Mark S / Grayslake
