"GIC added insulation and air sealing in our attic. I had multiple bids and felt that GIC was the company that best understood what needed to be done to make our home more comfortable and energy efficient. The team was thorough and did the work quickly and efficiently. I was impressed with their attention to detail and I look forward to a much more comfortable home this summer."

"Extremely satisfied! We needed attic insulation. Very happy with the inspection, bid and the Very prompt result. These guys are wonderful! Courteous, respectful and explained the whole process in detail! Would highly recommend ?!"

"The company was efficient and communicated well. I had several opportunities to check every area they worked on over and didn’t find anything they missed or skimped on. I went with their wet blown cellulose for my interior walls. It dried quickly and remained in place for a few weeks until my drywall went up."

"The customer service is great and they did a good job."

"John is very professional and self motivated. He shows up when he says he is gonna and does a very fine job of air sealing and insulating. Goes over and above. Highly recommend."

"Ben did outstanding work, for a very reasonable price. He was on time and extremely courteous and honest. I would definitely hire him again."

"Sky insulation did an absolutely phenomenal job. I have never come across a contractor as knowledgeable as Ken is. We are using him for all of our projects going forward no matter how big or small. Five stars all the way!"

"Excellent work, competitive pricing and hard working staff! After initial consultation Mauricio gave me multiple options of insulation level for my attic to bring it up to date and/or blow in additional and that's what's I decided to go with. On the day of appointment their team got right to it and figured out best point of entry and only took a few hours to complete the job! They come with a special ruler indicator that verifies the insulation is to the level requested, then after a quick clean up they were on their way to the next job with another satisfied customer. Overall a great help and I've already booked them for some additional work in my basement as well! Would definitely recommend C4 insulation for all your home needs!"

"Overall it went very well.  They started the job earlier than promised, they were good at handling unusual problems, and they did a good job of taking care of my change orders.
