"They had to come back for finish ups. Then they had to come back to blow in additional insulation, wrong amount blown the first time. The installers out a nail through an electric cable and it meant I had to call electric service people to replace IGF in the garage. I also had to have a freezer repaired because of the short. Insulation manager said he would pay for service calls, have yet to see the payment. Believe I will see the cooling and heating savings in the future but the company needs to be more careful overall."

"The process to remove the blown in insulation and the install of the foam was a 2 day process. The guys were efficient with their time and did a great job. I am happy with the results"

"He is a great guy and does a great job, he does what he says."

"Webb Durden delivers! Awesome job!!"

"Jose and crew did an awesome job insulating our attic space - timely, quality workmanship, clean up and reasonably priced. Highly recommend!"

"The project was top notch. Not only did they consistently show up on time, but they finished the project early and very Professional. Final project turned out great"

"They inadvertently removed some attic insulation while working on our neighbor's ajoining home, but replaced it promptly when advised."

"These are the "go-to" guys for spray foam insulation. I would recommend them any time. They were friendly and efficient."

"Carlos is AMAZING! I called C4 because I strongly believe in supporting the small businesses. I have no regrets. He Came out the same week I called. He is a small company with a great amount integrity and honesty!!! Price was very fare with quality work! Hard to find all this from one company. Highly recommend!"

"Awesome experience. Purchased home with open crawl space that was deteriorated with hanging insulation, and breeding ground for rodents and waste. Researched crawl space options and interviewed several companies to compare. Greg was honest, informative and provided an option that encapsulated the raised crawl space, complete with dehumidifier and thick vapor barrier. He promised to come by annually to check and make any necessary adjustments and stood by his word - we had the project completed in 2015 and he came back in 2016 adding some sealer to small gaps that occured and will be scheduled him again to return soon for 2017 service. VERY happy we completed - the house smells much better (they disinfected underneath and spent time ensuring joists were clean), air quality and comfort level is greater and greater peace of mind with rodent exclusion. Would HIGHLY recommend Greg and his crew"
