I feel very fortunate to have found Ideal Attic Insulation to work on the attic and crawlspace of our newly purchased home. From the start, Jorge came to provide a free inspection, and he was extremely professional and thorough. He personally went into the attic and crawled into the crawlspace to check every detail. After his inspection, he gave us a very fair estimate with a clearly written and complete scope of work. We also requested quotes from other companies, but it became clear that Ideal Attic Insulation—and especially Jorge—was the most professional, responsible, and knowledgeable. Jorge even helped us connect with other reliable handymen for additional repairs we needed around the house, which we truly appreciated. Once our plumbing repairs were completed, we scheduled the attic and crawlspace work. Jorge’s team handled the attic cleaning, sealing, rodent-proofing and new insulation installation. In the crawlspace, they performed a full cleaning, rodent-proofing, and installed a new vapor barrier. The scheduling was quick, and everything was completed within three days. The workmanship was excellent—clean, organized, and very professional. We really trust Jorge and appreciate his honesty, experience, and dedication. I highly recommend Ideal Attic Insulation to anyone looking for attic or crawlspace services. We will definitely continue using this company in the future. Highly recommended!
Jorge is the best. My wife and I had contacted 4 companies, and by far Ideal Attic Insulation was the winner. With us it wasn't all about price, but quality, knowledge of the trade and experience. We had our old insulation removed when we replaced our roof. Yes, like lot of us when your roof is compromised you have issues with rodents. Once our roof was completed, we set our appointment with Jorge. He came out the following afternoon, and boy was it hot. He inspected our entire attic and came up with a game plan to vacuum and sanitizing our entire attic space. He took a lot of pictures and shared areas of concern with us. We had the roofer's comeback out and tighten up area that may have been able to be compromised. once these areas were tightened up Jorge sent out his crew to install mess wire and stray foam around vent pipes, etc. Jorges recommended we wait a few weeks to install the insulation to see if there were any signs of rodents. After a few weeks and weekly inspections by Jorge and his crew, there were no signs of pests. They installed the insulation, and we could not be happier. We highly recommend Ideal Attic Insulation. Don't waste your time looking for other insulation companies call ideal Attic Insulation and know you made the right decision.
After reaching out to several insulation companies and getting quotes from 4 of them, we picked Ideal Attic to clean, rodent proof, and insulate our attic and floors as well as cleaning the ducts on our house that lies deep in the Santa Cruz mountains. Jorge got me an extremely competitive quote, and even after pressing the rest of the companies, Jorge’s original quote was still way below the other companies’. He sent out two teams the following Saturday and got everything done in one day. Everyone worked extremely hard and everything got done as promised. The attic team ran into a problem with a recessed light that went out while vacuuming in the area. They weren’t able to fix it on the spot, but Jorge and his dad came out a few days later and fixed it. Overall I’m very pleased with the price, quality, and the company’s dedication to making the customer happy, and I would therefore recommend Ideal Attic.

Kamal and his team at CA Attic Solutions did an awesome job in my attic! They handled insulation removal, rodent proofing, sanitation, air sealing, and installed new R38 insulation. The crew was super friendly, worked fast, and kept everything clean. My attic looks great now and the house already feels warmer and quieter. Definitely recommend these guys
Kamal and his crew did an excellent job with our whole-house fan installation. They were professional, punctual, and kept us informed throughout the process. Communication was clear and timely, which made the entire project smooth and stress-free. The team was respectful of our home, cleaned up thoroughly each day, and paid great attention to detail in their work. Everything was completed on schedule, and the results are outstanding. We are very happy with the quality of the installation and the overall experience. I would highly recommend Kamal and his team to anyone looking for reliable, skilled, and trustworthy professionals.
Exceptional Service – Highly Recommended! I recently hired CA Attic Solutions, and I couldn’t be happier with the results. Nadim and his crew were absolutely fantastic from start to finish. Nadim was professional, honest, and took the time to explain every step of the process—from the inspection to the final cleanup. The crew arrived on time, worked efficiently, and treated our home with great care. They handled everything from insulation removal and installation to rodent proofing, and the difference in our home’s comfort was noticeable almost immediately. It’s rare to find a team this reliable and dedicated to quality work. I would highly recommend CA Attic Solutions to anyone in need of attic services. Thanks again to Nadim and his crew for a job well done!

We went with Remove, Seal, Sanitize old insulation in effort to identify if there was a Termite swarm. We figured we’d need one day for termite inspection and a separate day for a termite treatment. The day after Attic Pros we had Bongiorno termite inspection come out and he went into the attic and there was no swarm identifiable all clean. Attic Pros did the complete removal and everything was visible and clean. It was cold at night and we didn’t wanna wait for our pre-scheduled couple of days out so I contacted Attic Pros and they came out the next day. Three guys installedR38. Bats without paper backer minimizing mold- they did an excellent job. All of our light was sealed. The hatch got new layer of bubble wrap insulation. The Attic vents had chutes installed allowing fresh air interchange. Can feel the difference- absolutely a warmer house. Thank you Attic Pros. Also Attic Prod had low cost to many other HVAC companies that just farm it out to subcontractors. Highly recommend Attic Pros.
I was able to self schedule an appointment within 2 days. Rabi was very professional and clearly communicated both the issue and the plan for resolution. They were able to complete the work within a few days. Their price was competitive. The team arrived between 10 am and worked all day to clean my attic, close all access points, and install the new insulation. They worked all day until 6 pm. They were very pleasant, answered my questions, explained things well. The process was pretty quiet so I was able to work at my remote job while they worked. They left everything clean in the crawlspace and took all garbage with them. I did not enjoy having creatures in the attic but they made the process of getting rid of them as pleasant as possible.
This is an excellent Company: They are professional, caring and thorough in their work. They took before and after pictures which was a great help. They removed rats, mold, asbestos from the attic. They removed the installation and replaced it with new. They sealed areas where the rats could have entered. They set traps and so far no sign of rats. They left my house clean. I have confidently referred you to my neighbors. Thank you.

We had a very good experience with Carlos. He is very reasonable and responsive. His crew is very professional. We had to pause our project with him due to other ongoing projects. Carlos is still willing to continue our project after one year of pause.
Carlos did a fantastic job replacing the insulation in the attic at our home in SF. He responded almost immediately and was available to complete the job the same week, and he was very fair on pricing. I would recommend his team and would use him again in the future.
Carlos and his team did a great and thorough job insulating an attic with a combination of batt and blown-in fiberglass. The work is super neat with great coverage even though the attic was challenging to work in. They were done in less than a day and treated the house with care. Highly recommend!
