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).

Bryan answered my project on Yelp and was the first to come and give me the quote. I knew from our interaction that we wanted to go with him. He was nice and didn't try to up sell us on anything. Told us what he saw and our straight up options. We knew what we wanted. We got a couple other quotes from other guys that were pushy with options and we knew they were giving us additional services even though it was obvious that there was no rodent activity in the attic. Bryan gave us a very competitive and reasonable price. His crew came, did the job, was super chill, and completed the job. House feels amazing now! Bryan, if you're reading this, you and your crew are awesome.

Over the past few years our HVAC system has struggled to keep up with the summer heat. With a new…read moreenergy efficient AC and doors & windows it still struggled. The missing puzzle piece was the insulation in our attic. It was in a pretty sorry state. I asked our HVAC installer, Airmaxx, for a recommendation and they directed us to Dan. I'm glad they did. Our service included a clean-out, rodent/pest proofing, sanitization, air sealing, and new insulation. The improvement to indoor climate control was immediate! The temperature across the the upstairs bedrooms is even now and the AC doesn't run constantly. The crew was on-time, courteous, professional, and fast. They kept us updated on progress and cleaned up before they left. 5 star experience. Finally, the pricing is competitive with the national average for the services we received. So if you're still deliberating or searching for a company, just go with CA Attic and Build. Your home is going to be more comfortable, and you'll save money upfront and in the long run.

If you hate your home, money, free time & love additional hassle, look no further you've found your dream company. WHAT AN ABSOLUTE JOKE !! Update: You have to love their cut & paste response, do I find it surprising they couldn't figure it out considering how bad they botch their jobs, NOPE !

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.

We have a home that has a basement. It has three opening with about 3100 sq ft of storage. During…read morethe 23 years we have lived here it became an area filled with everything that we brought from our prior house and a dumping ground for anything else. It also became to home to rats, rodents, urine, feces and chewed up belongings. It became obvious that this was a real hazard. Trying to find a company that could perform all the services that would be needed was difficult until I contacted Advanced Insulation System. There are not enough superlatives to describe this company. Everyone I have had contact with is professional, personable and hard working. First they had to empty the contents of the basement, which was an enormous job. I will show photos. Once emptied, the hazardous things, rats, rodents, feces, urine, chewed up belongings were removed. All the areas were sanitized and sealed against any intrusion by creatures. Heavy insulation plastics were used on the foundation and floors and insulation was blown in to seal the entire basement. They assigned workers to assist me in sorting out the contents of the basement. The things that I wanted to keep were sorted and placed in the basement, charity items were separated and they loaded up anything that was not salvageable in their big truck and took it to the dump. It seemed overwhelming until the fellows, who are very organized, helped me make decisions about what to keep, give to charity and throw away. This took many days and the crew were spectacular. They left everything clean and organized. I really appreciate the dedication and expertise they showed in dealing with this unhealthy and messy condition. The employees all represent the company in a positive light and I wouldn't hesitate to recommend them. I feel that their pricing was fair and everything was done to perfection.

I'm writing this review specifically for Mark. Mark from Attic Construction is extremely…read moreprofessional and really takes his customer service seriously. He made sure to follow up multiple times and ensure that we were getting all of our questions answered in order to make an educated decision on our attic clean-up project. Mark even removed a dead rat that we caught on a sticky trap for us; he really went above and beyond. He stayed with us after evaluating our attic to explain the bid while most of the other attic companies I received quotes from just went in our attic, asked for my email and left (I didn't even look at their bids if they did that to be honest). We didn't ultimately go with Attic Construction as another company came in with a lower bid to remove the insulation, sanitize and rodent proof (the clean-up is what we really didn't want to do due to rodent infestation). We'll be installing our own insulation at a later date after some assessment for future renovations since we're a pretty capable family (and poor ) but if we were looking for someone to install insulation, Attic Construction is who we would go with due to Mark's professionalism and obvious knowledge of how to do the job correctly and affordably. I like that Attic Construction has an electrician on staff as well to install attic fans; other companies did not have this option and we would have had to hire an electrician after. Mark was also very tolerant of my toddler who thought he was a friend and wanted to use him as a jungle gym . Gold star give this guy a bonus

I don't usually write reviews, but my experience with Thermal Advantage and Brody truly stood out…read more Contractor interactions often end in frustration, so when someone delivers exceptional service, it's worth sharing. Brody was flexible with my limited availability, arrived on time, communicated clearly, and completed the entire job on my 1,300 sq ft home in just four hours. He and his apprentice Luke worked efficiently and quietly, protected the work areas, and left everything spotless. Brody also used a thermal imaging camera to confirm each wall cavity was properly filled, which gave me a lot of confidence in the workmanship. The results exceeded my expectations. The patched holes are barely noticeable--I was prepared for my walls to look like a cheese board, but they look great. Brody was honest, fairly priced, and delivered excellent service from start to finish. The insulation product itself impressed me as well. As a façade engineer, I understand the value of insulation, but I didn't expect to feel such a dramatic difference so quickly. Within hours, the heat inside my 1945 home dropped noticeably, making it far more comfortable during peak sun.

We are looking forward in making our home more engery efficient and also saving money on our electric bill. We would highly recommend Thermal Advantage of California to anyone looking to drastically improve the insulation of their home.

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!

In August 2025, we contracted with Super Green to clean and replace the insulation in our attic…read more Everything went well at the beginning. The workers were on time and they were very quick to start and finish. They cleaned up after themselves and were done within 5 hours. Bad part was they missed cleaning an area of the attic, didn't clean off the top of the heating system unit that they said they would do and there were areas that could of used more insulation. I tried to call the site inspector Avi , no response. I called the main office and was told he was on vacation and to call him the next week. After two weeks, I finally received a call back from Avi. Avi asked me to climb up into the attic and take pictures to send to him. I told him that I was not going to climb in the attic and that I was surprised he did not come after the work was complete to ensure it was properly cleaned. He said he would call me back and set up a time for him to inspect. It's now October 2025 and still no site or response from Avi. My advice is that before the workers leave, if you are able to climb and check the attic, do it, because you will never see them again!
