"We used Carlos in 2019 to install insulation over our garage to reduce summertime heat. The project was very successful and brought temps down 10-15 degrees. In early 2024 we used him again to R30 install mineral wool over our media room and adjacent walls to soundproof. His crew was on time, professional, and cleaned up before they left. Carlos followed up with several calls to verify that I was happy with the work. Highly recommended!"

"I reached out to Carlos about a my remodel Im doing. He showed up the next day to look at and quote the work I needed done which was a ceiling spray foam. His crew made it out, were on time and got the job completed professionally. They care and take the time to prep and clean up which you dont see a lot. I would recommend Carlos to anyone in need of insulation service."

"I had Carlos and his crew install additional attic insulation to my home. His crew arrived on time and worked until the job was finished and then cleaned up all of the debris. The crew worked swift fully, skillfully and in a safe manner. I recommend Carlos for residential insulation installations and upgrades."

"We asked for a recommendation from a contractor we trusted for someone to add insulation to our attic, he suggested Carlos and so we called him. We hired Carlos to add fiberglass batts and he came the next day. His crew was polite, worked efficiently and had me check their work when done. Everything looks great, very professional and we are very pleased with the job."

"Carlos Insulation really took good care of us. Much of the insulation in our crawl space had fallen down and needed replacing, as well as strapping up the rest to keep it in place. Not a big job, but an important one. I arranged the scope, schedule and terms with Carlos himself in one phone call. His team showed up on time, knew exactly what to do and finished in less time than expected. They were clean, professional and were even prepared to go under the house again to look for our cat (who was thankfully hiding under the couch). They also took before and after photos of their work that were quite valuable. A final phone call with Carlos before they left settled the price on the exact terms we agreed to earlier. On time, on budget, superior performance. That's what you get from Carlos Insulation."

"We had our old (1965) attic insulation removed (including some asbestos) and replaced all the ducts and vents and added new insulation on a 1600 sq ft house in Davis by Carlos Insulation. The total project was $13,000. It was all done quickly and efficiently. They put a plastic shield up to keep the particulates from getting into the rest of the house. All the workers were good to work with and cleaned up their workspace very well. We are noticing a very significant improvement in the efficiency of our air conditioning."

"I needed to do a spray foam insulation in my ADU ceiling and spoke with several companies. Carlos was able to visit the property within a few days of discussing the project and provided a quote that same day along with helping me better understand all of the options. I decided to move forward with Carlos and was able to schedule the work quickly and the quality was great. It passed the city inspection and Carlos provided the documentation I needed. I definitely recommend Carlos Insulation."
