    Installed rockwool
    April F.

    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!

    Just a warning, this review is going to be pretty long. But if you're thinking about reinsulating…read moreyour home, that's a pretty big task, so I'll add as much detail as I can to help you! Background: The credit for green energy was ending in 2025, and I had always wanted to reinsulate my home because it was so cold in winter and super hot in summer. I went through many different companies and seeing how people felt about them, and I saw a lot of horror stories. I called up a few companies and found out that insulation is kind of like roofing, where a sales person and a tech comes, where the tech looks around and the sales person tries to scare you into using their company right then. They might say something like "your attic is super hot" (that's normal, well, up to a point), or "we'll give you a special deal if you say yes right now". Just kind of shady stuff overall. One big thing that people mention is that while insulation is good, you need to airseal your attic as well - this was another thing I was looking to get done. Initial Meeting: So I was kind of expecting that when I called Attic Professional. Fortunately, that was not the case at all! From other reviews you might have figured that the owner, Bryan, is incredibly respectful and treats customers well. I got to experience that as well. One thing I was surprised at is he had inside shoes (the kind you see in Japan) and put them on and off when walking around the house. He went up into my attic and really dug around to look for issues like pests or mold (besides the poor insulation layers). We went around the home together to look for clogged vents. He didn't try to sell me on anything - I remember reading one review that said he didn't try to sell them things they didn't need, and that was my experience too. He said they could put more insulation in on my existing one, or take out the old one and put new one in; but neither would have a substantial difference. I went ahead and asked him to remove the old insulation and put new insulation in just for cleanliness. I even later changed my mind and asked for a custom insulation scheme - some fiberglass batting and mostly blown-in, and he had no problem accommodating that. Oh, and they would include airsealing gaps in the attic with fire resistant foam! Reinsulation: A few weeks later, he and his team brought his truck up to my house. They covered many surfaces with plastic drop cloth to prevent insulation from flying around - they taped doorways so I could come through, and they taped cardboard to corners in the house so their insulation blower tube wouldn't cause damage. They put canvas drop cloths on the floors to protect them. There was a bit of fiberglass and debris around after, but it was very, very minor. I understand how difficult it is to be flawless with cleanup, but these guys were very good. The work was smooth and quick - only a few hours. I didn't have to add much input and the team was in and out. Bryan left for another site for an hour or so, but everyone was just as respectful as Bryan, and they told me he was a very good person to work for. Always nice to see that the employees have a good opinion of the company as well. One thing that I thought was interesting is after they removed all the previous insulation, they let me look at the attic and see how they stapled their measuring tapes. Apparently, some insulation companies will scam their customers and fold up their measuring tapes so it shows more insulation than what's actually in there. I was able to verify myself that all the measuring tapes were correct. Bryan and I did a final check on the attic together and I was very happy. Above and beyond: A month or so later, I was very curious about the insulation and really wanted to optimize the house, so I got one of those FLIR guns (temperature sensor guns) to see if the attic was perfectly insulated. As expected there were a few spots that had a bit of uneven insulation (after all, nobody's perfect), but for the most part everything was good. I sent Bryan a text about these spots, and he immediately he and his crew to come add some more insulation and pack it in. Now everything on the camera looks great. I think it's pretty rare to find such attention to quality, and I was very impressed. Results: In the San Diego weather by home would average 63 degrees when outside it was around 48. Now, the house never drops below 68, and it averages around 72 year round. When it's 85 degrees outside, it might be 76-78 inside. I've seen the temperature inside crack 80 maybe twice in the last year, and never seen it below 65. This is with no heater, no AC running EVER. So TLDR: I would completely recommend using Attic Professional for your insulation. Take a look at their price, but I find their quality far outshines anything I've seen, and I think I got a steal of a deal (with the now-removed credit sadly).

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 accepted and thought the date was locked in. Sadly, the date we thought we agreed on came and went. So, we texted Paul and asked for clarification.

He was on time, kept the dust and mess contained, and when he left, we had a functioning whole house fan, and no sign that any work had been done (clean and fresh paint). Overall, other than some communication challenges, it was a great experience and we're happy with the results.
