"Fibers Insulation was extremely professional right from the first call. I chose their service from Angie’s Lust and within minutes Geovany responded. He came out on a Saturday to provide a quote and followed up days later. Members of the company were here at the designated time and did a stellar job! I insulated my garage to add better barrier for my garage to enhance a new AC unit to offset summer heat. Geovany followed up after the installation to ensure all went well. To ensure a better look, taping will be added to keep it looking great. I will recommend them to others in my gated community as I am very pleased with the result."

"Rob was amazing! I wanted to get my attic insulated, my house was built in the sixties and had never been updated to current standards. Was able to get an estimate within 2 days and when he came he inspected throughout to see if there were other problems which he found from when we replaced out AC ducts. Estimate was extremely reasonable and was able to get a insulation date the following week. Luckily we were able to get this done before the heat waves started and I already have noticed the improvement on retaining ideal temperature and my AC runs much more efficiently and has to run for less time. Cant recommend this company enough!"

"I was happy with the process from start to finish. The company is very dependable and does good work. They cleaned up before and after insulation which I appreciated. He even told me that my ductwork needed to be looked at. He told me that he would wait until I got that fix to finishing my insulation. Which I thought was thoughtful of them to do. They are flexible and reliable, I would 100% recommend this company."

"Good company to work with! They were very nice and seem to be honest over the phone as well. They came on time and did the job. My A/C system didn't work good and a strange smell came out of the ducts when I turned the A/C on. 
Jose that did the work, checked everything and connected a machine to the system letting it run for a while and added a cleaning chemical that made this smell gone.
I will hire them for the future. it was a hassle free with this company.

FAQs for insulation service projects in San Jacinto, CA

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.

It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.

Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
