  This company has my highest recommendation. We replaced old insulation that was damaged by rats infiltrating our crawl space from a canyon below our house. The CEO (Matt) personally inspected our home and developed an estimate to clean and rodent-proof the home, and included options to replace the insulation with foam or fiberglass, depending on our budget. I am so glad we chose foam for a long-term solution. It is also far superior. We can already feel the difference in temperature inside. The entire team (from cleaning to installation) was knowledgable, professional, and friendly. Also, the company stands by its rodent-proofing work with a 10-year warranty. I could not be happier with them and their work!

  Leaving this review months after their service. We had a roof leak and during repairs found signs the attic had previously been infested with rodents. These guys came out and did great work remediating/sanitizing and installing new batting. Excellent communication all around, hard working team, and they even went the extra mile with some small requests I had at no charge. What really set them apart was when I reached back out to address a minor mistake they made which was found after they completed work, Matt immediately resolved the issue.  Genuinely impressed with these guys. This is how a business is run. Thanks Matt, Cole, and the rest of the team.

  I worked with Advanced Insulation System to install new Insulation and drywall in our garage. Despite some minor setbacks, Matthew and his crew were able to do it right and we got an amazing transformation! Thanks to AIS for the renovations my parents are extremely happy with how things turned out!! Definitely recommend!

  I recently had Advanced Spray Foam insulate the attic rafters of a house I'm working on for a family member in El Cajon.   If anyone is considering the value of the material,  we had our attic temps drop from 130 on average to basically air temp outside.   Price was very competitive and the team that did the install and clean up were very respectful of the house and kept things clean. I also used the attic clean out service they offer to remove an old re-roof job that had filled the space with debris and old blow in that was full of mice remnants.  Again another team that was extra careful and did a great job. Matt and John the owners give timely status updates and the contract process was fair and no pressure.   I will use them again in the future.

  We had a smell coming from our kitchen ceiling duct after using our air conditioning system during the hot weather. Mathew came over and did a free inspection and was very thorough.  They checked everything in the attic and also inside the kitchen ducts and they didn't find anything except dust. They recommended getting a company to come out and clean the dust out of the ducts and to use a deodorizer. They did an excellent inspection and helped us resolve our issue very quickly. We will definitely use their services again and he said they also offer installing new insulation in the attic and adding sanitation to help with conserving energy.

  I can’t recommend this company enough. I was having trouble keeping my house cool even after recently paying another company to install attic insulation. Instead of trying to sell me on more work, they took the time to thoroughly inspect my attic, checked multiple areas, and even drilled a small inspection hole to verify whether insulation had actually been installed. It turned out there wasn’t insulation where there should have been. What impressed me most was their honesty. They encouraged me to contact the original company and have them correct their mistake rather than trying to profit from the situation. They spent their time inspecting everything, explaining what they found, and didn’t charge me a dime. It’s rare to find a company that’s this knowledgeable, honest, and genuinely looking out for the customer. When I do need insulation work in the future, they’ll be the first company I call. Highly recommend!

  Extremely happy with our insulation job in our two story home. The team was professional from the first visit and offered a reasonable price for all the work required. We feel it was well worth it and would recommend the team to anyone looking to redo their insulation! - Phil & Brenna Frost

Why Fire-Resistant Attic Ventilation Is Critical for Wildfire Protection!

Most homeowners don’t realize their attic vents are one of the weakest points when it comes to wildfire defense. Standard vents allow wind-driven embers to enter and ignite your home from the inside, often before the flames even reach your property. Fire-resistant attic ventilation blocks these embers while still allowing your home to breathe, keeping your attic safe, compliant with modern fire codes, and better protected from extreme heat. Upgrading your vents isn’t just smart—it’s essential.

The Dangers of Outdated Attic Vents in Fire Zones

Old or non-compliant attic vents leave your home vulnerable to wildfire embers, which can enter your attic and ignite fires—even if flames never touch your property. Without proper fire-resistant ventilation, your home is at serious risk during fire season. Many insurance providers are now requiring homeowners to upgrade vents to maintain coverage. Don’t wait until it’s too late—protect your home before the next wildfire strikes.

Benefits of Fire-Resistant Attic Ventilation

Upgrading to fire-resistant attic vents offers more than just wildfire protection. These modern systems are designed to block embers while still allowing your attic to breathe—helping regulate temperature, prevent moisture buildup, and improve overall energy efficiency. Proper attic ventilation also reduces the risk of mold, extends the life of your insulation, and keeps your home safer, cooler, and compliant with local fire codes.
