In 2008, Insulation Co. LLC was Established by its owner and operator, Jo. Jo has been installing insulation since he was 10 years old, learning from his father. His parents taught him that nothing comes for free, and Jo began working in crawl spaces at a young age to earn the luxuries he had. With time, Jo started his professional career at one of the biggest insulation companies in the world, where he gained hands-on experience and knowledge of how to properly remove and install insulation. As he progressed in his career, Jo realized that opening his own company would be the best option for his future and family. Thus, Insulation Co. was born. With years of knowledge and experience, Jo provides customized consultations to each potential customer, explaining why the recommended services are needed. As a fact-based sales company, transparency is essential for Insulation Co. from the very beginning.

“Insulation Co. LLC was great. Can’t recommend them highly enough. Jo Estrada gave us a bid in a timely manner and the workmen, led by Julio, showed up early and worked hard, well and did a terrific job. They did things above and beyond particularly with our dryer vent. It was a messy crawl cleanup and insulation replacement with limited space to work. We couldn’t be more pleased. (They had to come by ferry to our island which made it all the harder for them but it didn’t stop or delay them from doing excellent work.) We were even contacted with immediate followup by Jo. All companies should be this good.”

“The Insulation Company did a great job for us. Our house is warmer and the furnace does not run as often. Also, they were willing to vacuum the very old insulation from our attic and then return at a later date to re-insulate. This allowed me time to fix and upgrade a few things in our attic without crawling through a nasty dusty mess! Would highly recommend them!”

Chris Mackay


“Insulation Co did a clean-up of a crawl spaces that had a rat infestation last year. Some of the spaces were really tight and nasty. Jo’s team came in on time, cleaned out all the torn-up insulation and replaced both the vapor barriers and overhead insulation. The work took less than a day and was better than the original. I did a lot of research and Insulation Co gave the best value for cost by far. I fully recommend them for crawl space work.”
