I had a great experience working with Advanced Insulation Systems. John and Mathew were both professional, knowledgeable, and easy to communicate with throughout the process. They took the time to understand what we needed and helped us find a practical solution that worked within our budget. The team was responsive, worked quickly, and did a quality job. I appreciated their straightforward approach and attention to detail. Would definitely recommend them to anyone looking for insulation work.Posted on Google

Victoria Fuller18 September 2026This 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!Posted on Google

Nic R24 August 2026Leaving 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.Posted on Google
Joe Bobadilla15 August 2026I 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!Posted on Google
Jon Van Sicklen14 August 2026I 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.Posted on Google
Jessica McDermott11 August 2026We 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.Posted on Google
