Had some minor issues during the install, but Nick was on top of it communicating every step of the way.

Our experience with Attic Advisor was truly exceptional from start to finish. Dominic handled the…read moreinitial assessment and quote, and he was so personable, friendly, professional and fast. 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

We quoted our attic air-sealing and insulation job with three companies last summer, and Russell's…read moreexplanation of options and answering of my extensive questions led to us to choose Guardian. 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!

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.

On Friday, July 24, Dan came to my father's home and quoted him $8,000 for the work. My father explained that he is on a fixed income, and could not afford that amount. Dan and dad talked, then Dan offered to do the work for $5,500 and allow my father to pay in 3 installments. Because my dad still could not afford the $5,500 without my help, he contacted me at work and asked if I could help. During that conversation, Dan told me that my father had a significant rat infestation and that the situation was unsafe because rats had allegedly chewed electrical wires. This made the situation sound very serious, and I became concerned about my father's safety. I agreed to help him financially and confirmed directly with Dan that the total cost would be $5,500 for the job to be done. Dad said he gave Dan 3 checks, plus a $500 deposit. I was surprised to learn that all 3 checks had been collected at that time, rather than when the work began. While writing the checks, my father made an error on one and had to write another. He told me that Dan was urging him to hurry because he had another appointment. Although Dan was not rude, my father felt rushed and unsure. On Wed, 7/ 29, I went to my father's home to meet Dan and his crew. Before they arrived, I spoke with Dan by phone and specifically asked him to explain what the work would involve. He told me that the crew would: Clean and vacuum the attic. Remove the existing insulation, debris, and rat droppings.Rodent-proof and seal entry points around the attic, house, garage, and roof using steel mesh. Sanitize the affected areas.I asked Dan specifically, "Then you install the new insulation?" He told me no, that new insulation was not included. I was shocked because both my dad and I understood that the $5,500 price included replacing the insulation. I mean if you remove the old you have to put new insulation right? I asked Dan for a copy of the contract my father had signed, and he emailed it to me. At that point, the crew had arrived and was unloading equipment. My Dad wanted time to think about whether to proceed. I told Dan that & Dan continued telling me that my dad needed to have the work done because the rat droppings were dangerous and that rats chewed on wires and ducts. I felt pressured to proceed, particularly because Dan already had my dads post-dated checks and was in my ear stating its not safe etc. Dan also told me that he could no longer honor the $5,500 price if we did not proceed at that time. I now felt pressured and concerned for my dadl He initially said the new insulation would cost $3,500, which would be $9,000. the price dad originally couldn't afford,He then offered to reduce the insulation cost to $2,500. I finally gave in to the pressure & concerned for dad I said ok do it. I subsequently had several conversations with Dan regarding the insulation. My concern was that the contract did not clearly state that insulation replacement was excluded, nor did it state that replacing the insulation would cost an additional $3,500. During my original conversation with Dan, I understood the agreed-upon price to be $5,500 for the job. If Dan said "by the way, insulation is Not included & will cost you more," I would have said NO at that time on 7.29 I was concerned because my father was left without insulation during a period of extremely hot weather. My father is 85 years old and has serious breathing and heart problems, so I was particularly concerned about his ability to remain safely in the home without the insulation being replaced promptly.On the morning of Aug 6 at 7:15 a.m., Dan called me while I was at work and told me that he had a family emergency and would not be returning until Aug 16 to install the insulation. I told him that I considered this unacceptable because of heat in Oside that week and his heath issues. I told Dan that I would consider contacting an attorney and he it wont stand and also will file a complaint with Yelp and the BBB, and call his office. Dan responded that there was no need to involve anyone else because the matter was between us. contacted Calf. Attic & Build& concerns to the recpt. She said she would have Ben, Dan's partner, call me. I spoke with Ben and explained the situation, including my concerns about my father's health and no insulation that was never on the contract.I mentioned my neighbor and I also went into the attic to look at the work ourselves. We observed rat droppings and areas where daylight could be seen coming through the structure, which raised additional concerns for me. Was it even SANATIZED! During my conversation with Ben, after I explained my concerns, I said I had someone come in & look at the work; he said, "Are you trying to throw me under the bus-shocked at what he said, I was trying to get answers & ensure the work dad paid for was properly complete

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.
