    Vapor barrier not secured correctly to the exterior stem wall.

    I would caution others before hiring this company. The quality of the vapor barrier installation in the crawlspace at my home in central San Diego Jun 2025 was very poor. The crew worked unsupervised and failed to install the barrier correctly--leaving gaps, exposed ground areas, and placing the new material over debris and old construction waste instead of clearing it out first. Two highly reputable, independent inspectors later confirmed that the vapor barrier was not properly sealed along the crawlspace perimeter, leaving the area vulnerable to excess moisture and potential mold growth. The lack of proper installation and oversight completely undermined the purpose of the project. After requesting twice during the final phone call with the company owners not to be contacted any further, they violated my request and sent harassing text messages.

    Crew did a great job installing my provided rockwool insulation at my home in Fallbrook. They were also very friendly and professional. Great job!

    Humberto and Alberto wrapping up the job with care.

    The team from Advanced Insulation System completely transformed our crawlspace, and did it quickly with great service and quality work. John came over and reviewed the job with me, provided a proposal the same day, and thanks to an opening in his schedule we had a completely clean, dry, vapor-barrier lined and rodent-proofed crawlspace just a couple of days later. His crew members were all friendly and professional. Thanks especially to Humberto and Alberto, who wrapped up the job on day two with great care and attention to detail. We'll gladly call these guys again with any other insulation need we have.

    The team at AIS did a fantastic job on our ADU insulation. Matt Hodlin on the front end with the proposal was prompt, clear and offered a competitive price. The execution team of Humberto, Roman and Alberto worked great together and finished the job on schedule and were very responsive to my requests. Clean up was complete and move out went per plan. Overall using AIS was a great experience with no hassles. I would recommend them without hesitation. el

My attic was in terrible condition due to a severe rat infestation from the house being vacant for a while. It was honestly horrifying, but they completely took the stress off my shoulders and handled everything with care. They came back twice to ensure there were no more rats in the attic and crawl space, which really showed their commitment to doing the job right. They recently completed the insulation as well, and the results are excellent. The owner and the entire team are incredibly friendly, professional, and genuinely caring. You can tell they truly value their customers. I am extremely satisfied and highly recommend them.

And while you may get a great sales person, sometimes the crew who actually does the work may come up short. Definitely not the case with Attic Heroes! Fidel is such an outstanding young man, that we cancelled the other two companies we had scheduled for quotes. Never have we done that, but Fidel made that much of a first impression. Thankfully, so did Tony and the crew! Our home is small and so is the cramped attic space. Nobody likes to go up there. Attic Heroes removed decades of old nasty fiberglass insulation and installed new blown in fiberglass in one day. Attic Heroes is a true dream team. They are friendly, polite, communicative, efficient, and take great care in protecting your home inside and out. On a scale of 1-10, this company is an 11!

He even took the initiative to repair a vent that had been left broken and unattached by a previous company (before we had even committed to moving forward!) On the day of service, Dominic called ahead with an estimated time of arrival, which was greatly appreciated. Tyler, Patrick and Mike arrived right on time and immediately began preparing the space with floor protection and plastic sheeting to contain any dust or debris. As someone who works from home, I also appreciated how quiet they were throughout the process. They provided progress updates with photos along the way, and the results were impressive--everything looked clean and well-finished. Tyler also shared images showing that they had corrected and properly sealed ductwork that had previously been patched with duct tape by another company. They completed the job well before I expected it would be done and then cleaned up and left the place spotless! Overall, a highly professional and very detail-oriented team. We had an attic restoration done previously, and the differences in the 2 companies were night and day. I would not hesitate to go with Attic Advisor again, highly recommended, 100/10 stars

Their quote was in-line with the competition as well. Russell has an extensive background doing these jobs himself so he knows what he's talking about. Russell also came over a second time to discuss options for routing our two bath fan exhaust ducts to roof vents when I weighed adding that to our scope. We executed our install over two days in October and everything went smoothly. After air sealing and adding soffit baffling, they blew R30 cellulose over our existing bats. We also added a gasket around our attic access and insulated the back of the panel. My only recommendation is that you, the homeowner, clean your house after the cellulose blowing. There will be fine paper material in the air everywhere, which will settle as dust. Seven months later and our house has been noticeably more temperature stable- warmer over winter and cooler during our recent hot days. Don't skip air-sealing, and make sure to quote with Guardian if you're looking for the best result for your house!

The other bids did not offer to stucco match or paint. They came out in one day in December 2022 and got it all done. The whole team was professional and courteous. After they were done, you couldn't tell that I had holes all over my exterior. It's been almost three months and this winter season feels colder than normal outside. But inside, my home feels warmer. Before my feet would be cold (since cold air sinks), but after the insulation it is definitely warmer. My heater is not working as hard. Plus, I might be able to write some of the cost of the insulation off on my taxes (still need to check that).

The Red trailer crew, in our case, just two gentleman with foreman being the son of the company, came in and quickly filled (in a little over an hour) our attic to its correct level of insulation. We are so glad we chose ACH to insulate our home, we finally have the comfortable cozy temperature that we require for the winter and summer months. In the long run, we can save Heating and Cooling savings with this insulation. We definitely recommend ACH!!
