"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."

"Very efficient and tidy. The work area was taped off well and he was very informative about what the product would do for my home. He knows all of the answers to all my questions pertaining his product and how it will efficiently work for me. I live in an old house that is very drafty. This winter my home has been very warm compared to last year. 10/10 recommend this business to anyone."

"I can’t say enough good things about this insulation service! From start to finish, the experience was absolutely top-notch. The team was punctual, professional, and incredibly knowledgeable. Mauricio took the time to explain all my options and helped me choose the best solution for my home. Mauricio also worked around my schedule going above and beyond with communication ensuring I was confident in my home improvement solution. The installation itself was seamless—efficient, clean, and with great attention to detail. I was impressed by how respectful they were of my space, leaving everything spotless once the job was done. If you’re considering upgrading your insulation, don’t hesitate—C4 Insulation is reliable, trustworthy, and truly cares about delivering quality results. I highly recommend them to anyone looking to improve their home’s comfort and efficiency!"

"The fellows did a great job with this house. The work is really quite excellent, and they kept us informed with how long it would take, how it was going, and could speak in understandable sentences. They were polite and they worked very quickly.
We were amazed and how quickly they did this job, as it was perfect and not at all sloppy, which you easily see in others who are quick and sloppy. They were anything but. They cut around several outlets and exterior items on the house and that was done well. I would definitely recommend to anyone. We also cannot believe how much WARMER THE BACK OF THE HOUSE is now - especially as it faces NORTH and was quite cold for the last 15 years. We hope to be able to have them do the rest of the house as we like the insulation put in and the type and quality of siding that was used. We would recommend most definitely."
