We've now hired Attic Masters for two different properties. The first in San Ramon that we were…read moreconverting into a rental and now another smaller unit in Milpitas. Both times the experience has been excellent. Like a lot of people, we kept putting this project off after Covid. At some point, though, you realize this isn't a DIY job and you need profs who know what they're doing. From start to finish, they made the process easy. They came in, removed all the old insulation, sanitized the attic, and installed brand-new insulation with zero hassle. Each job took just a couple of days: day one for removal and cleaning, day two for installing the replacement. Both times the crews worked efficiently and left the spaces as clean as could be expected. It is costly but not as costly as doing it yourself or ignoring a real problem.

This is the very first time I'm giving less than 5 stars for a yelp review. I usually like to give…read morecompanies the benefit of the doubt and give them opportunities to make it right, but my experience with Attic Masters and Adam have been nothing but endless frustration. First, they didn't show up to our scheduled appointment on Nov 29, at 8AM even after I received 2 confirmation emails, and text reminders about the appointment (attached below are photos of the confirmations). I specifically chose this company over Attic Bros because I was told that they work on the weekends and complete jobs on weekends. In hindsight, I wish I would have just gone with Attic Bros from the start. Two guys came at 2:30pm instead on Saturday after I had called them at 10:30am about how no one showed up. The 2 guys only put up 2 films of radiant barrier and left at 5pm. On Sunday morning, the remaining workers showed up and "finished" at 2:30pm, however they didn't rodent proof my crawl space until I had pointed out the holes to them. They did it after I had pointed out the holes. Additionally, they never rodent proofed my the attic side vents. They rodent proofed the roof, sure, but I would have thought the side vents would be included (they didn't have a ladder to reach it so they didn't do it). I had to hire a third party to fix the holes/gaps on the side vents instead because Adam and his company didn't want to come back to fix it. I was told they'd call me back when they can schedule me in, but after a week I gave up and just hired another company. Also, they damaged one of my kitchen lights when they were doing work in the attic. Adam also said he would send someone to fix it and that it's "easy" but nothing ever came of it. The 3 stars I gave them is because the insulation looks decent and that they still came on Sunday to follow through on the project, but if they could lie to me about "fixing the side vents from the inside" who knows what else they may have lied about. I am concerned about this company's integrity. Also- Adam is rude and defensive on the phone, and doesn't really let his customers speak.

Many thanks to the Universal Insulation team for doing such a great job on my attic from start to…read morefinish. We purchased our home many years ago and didn't realize how much of a mess the attic truly was until Universal Insulation completed an assessment in preparation for a possible heat pump installation next year. We're so grateful to have found a company we could trust to do things the right way. During my correspondence with Marko, Marko arranged for an assessment to be conducted by Nicholas. From the initial assessment, Nicholas was incredibly patient in addressing all our concerns and questions -- especially since we are very "hands on" homeowners. Once the contract was signed, Ann promptly scheduled us for the next available appointment and provided clear, detailed instructions on how to prepare before their arrival. The meticulous process began with removing the old insulation and debris, vacuuming the attic floor, and sanitizing the space. The next step was ensuring the attic was structurally sound and ready for new insulation. Because of the care and attention to detail that Marko, Miguel, and Nicholas put into every part of the job, we ended up with a dry, well insulated, properly ventilated, and easily accessible attic. If you're looking for an excellent insulation company, I highly recommend the team at Universal Insulation, Inc. -- they are truly competent professionals who take pride in doing things the right way.

Michael arrived right on time and was just as capable, professional, and pleasant as before. After thoroughly inspecting the attic and crawl space, he shared over a dozen clear photos showing that everything inside was spotless and in great condition. He even noted how fresh the air was, remarking that it felt like "we were here just yesterday!" Since my room doesn't have an attic or insulation directly above it, Michael explained that the noise was likely coming from animals on the roof. I'm so relieved and thrilled that the quality work Attic Bro completed in 2024 is holding up so well. Thank you, Michael, for your expertise and genuine care, and thank you, Attic Bro, for setting such a high standard!

They also showed us before-and-after photos, so we could see exactly what was done. We've definitely noticed a difference since the work was completed.

I cannot recommend the team at GreenShield Insulation and the owner, Ahmad, highly enough…read more Unlike several other contractors who either quoted me over the phone or barely looked into the attic, Ahmad personally came to my home, thoroughly inspected the damage caused by rodents, and provided a very fair and honest estimate. This project was unusually complex and took nearly four months to complete. The process involved rodent exclusion, removal of decades of accumulated insulation, asbestos abatement, attic sanitization, installation of new ductwork, and finally new insulation. Throughout every stage, Ahmad remained involved, checking in regularly and making sure everything was progressing. A special thank you to Dave and Eddie, who removed the old insulation and installed the new material. What appeared to be a straightforward job of insulation removal, turned out to involve three layers of different insulation materials dating back to the 1950s. Despite the unexpected workload and physical demands, they never complained. They remained cheerful, professional, respectful, and hardworking throughout the entire process. As a senior citizen who carefully researches major home repairs, I greatly appreciated Ahmad's patience in answering my many questions. He was consistently kind, knowledgeable, honest, and professional. Unfortunately, not every contractor I met during this project demonstrated those qualities. The entire GreenShield team exceeded my expectations. Their workmanship, integrity, communication, and customer service were outstanding. I would not hesitate to hire them again and highly recommend them to anyone needing attic insulation, rodent damage restoration, or related services.
