EXCELLENTBased on 33 reviewsTrustindex verifies that the original source of the review is Google.David Hanna2024-09-26The results I got surpassed my expectations. Within just a couple of days we noticed a marked difference in how my home was cooling and especially how much the A/C was running - and this was in July! I'm looking forward to seeing the effect this winter and have already seen an impact on my summer electric bills. My A/C system just seems to be more effective even though all I did was insulate my home better - something friends who have done this work told me about, but now I get it. Marc had excellent communication with me, and the installation team was super fast, efficient, skilled, knowledgeable, experienced and professional. All completed in one day. Marc's prices are reasonable and competitive, and he has a lot of experience that ensures the job will get done properly. He is conscientious and personable. Highly recommended.Trustindex verifies that the original source of the review is Google.A Hendershot2024-09-17GCS was the first insulation company where I spoke directly to the owner. Marc is very knowledgeable and his prices are competitive. The team got the job done in a day and we noticed the temperature difference immediately. Overall, it was great experience.

The team arrived early on a very hot morning and sprayed the attic thoroughly. Alex was lead and the team cleaned up and worked efficiently. I don’t know how they persevered in the heat. After the insulation dried, the temperature difference could be felt. We were very diligent in exploring various insulation options and companies. We are pleased with GCS and feel comfortable referring them to others. I am optimistic that our power bill will also reflect the installation with a decreased amount next month.Trustindex verifies that the original source of the review is Google.Nick Anderson2024-03-28We had a great experience with this team. They were very professional, on time, and neat. We hired them to come last minute and clear the existing blown insulation above our living room/kitchen mid project and they did a great job of keeping the mess to a minimum and cleaning up behind themselves. We plan to hire their services for future projects and would absolutely recommend them to family and friends!Trustindex verifies that the original source of the review is Google.Good People News2024-03-27They did an excellent job at our new offices!Trustindex verifies that the original source of the review is Google.Emily Fish2024-03-07Excellent service start to finish - owner answered and visited for the quote.
