They completely removed the old, contaminated insulation, cleaned out all rat droppings and any evidence of rodents, sealed every possible entry point inside and outside the home to prevent future access, and installed new good quality insulation. Their work comes with a 3-year warranty. They provide before-and-after videos and photos so we could clearly see the work that was done. The entire crew was courteous, professional, hardworking, and kept everything clean from start to finish. While this was a significant investment, it is worth it. We had been paying a pest control company for months, and nothing solved the problem. Attic Elite addressed the root cause instead of just treating the symptoms. We hope to continue to see success in the years ahead. The sales rep was knowledgeable, friendly, and professional. He took the time to answer all questions, and never felt pressured to hire them we did obtain other quotes and Attic Elite offered very competitive pricing.

From the start, Omar was professional, knowledgeable, and easy to work with, clearly explaining the scope and offering helpful recommendations without pressure. On installation day, Kelmer and his team were punctual, efficient, and careful, completing the work smoothly and leaving the area clean. Omar also checked in during the project to ensure everything stayed on track. Communication was excellent throughout, and Omar helped coordinate seamlessly with our roofing project, working well with our roofer to align timing. Overall, the project was well managed from start to finish, and we are very satisfied with the results.

We had a terrible experience with this attic company from day one. What should have been a simple…read morejob clearing and cleaning our ducts turned into repeated visits, unexpected charges, and ongoing problems that never seemed to get properly resolved. Initially, they tried to overcharge for what appeared to be a basic service. After the first visit, we continued having insulation coming through our vents, so we had to call them back. During a follow-up assessment, they claimed there were additional damages causing the issue, which led to more scheduling and more costs. Unfortunately, even after that work was completed, we still experienced insulation problems and had to contact them again. It felt like every visit resulted in new charges without real solutions. The most concerning part came after their final visit was that our heater suddenly stopped working. We brought in another vendor to assess the situation, and they identified damages to the heater, including a clogged component and poorly performed replacement work that appeared to be related to the previous service. Overall, this experience was extremely frustrating. Multiple callbacks, escalating costs, and ultimately more damage to our system are unacceptable. We would not use this company again and do not recommend trusting them with your home or HVAC/attic services.

The staff on-site was great. Diego kept checking in with me and being transparent. They did a very clean job. Left not one spec of dust behind. The only thing I want to call out is that original inspection came back with one quote, and on site they said I needed more done upstairs. I would of hoped they caught that prior-- so we opted out for now. But I'm not taking down the stars because I don't know the complexity of finding more damage when you're actually in there. Happy with the experience. Will see how it goes the next couple months with rodents.

We were initially told by another HVAC company that we needed to replace all of the air ducts and…read moreinsulation in our attic, add insulation in the rafters, and address rodent droppings in the crawl space. When Elmer came out, he took about 30 minutes to walk through the house and gave us a completely different--and much more reassuring--assessment. He identified entry points where rodents were getting into the crawl space, explained that the air ducts did not need to be replaced, and instead recommended insulating the rafters, reinsulating the attic floor, and cleaning and reinsulating the crawl space. He also suggested installing an attic fan to improve air circulation. Throughout the visit, he was straightforward, knowledgeable, and very approachable. We decided to move forward with the attic fan. Umar updated the contract promptly and even came out personally to help program the fan and connect it to my phone. Their team worked tirelessly over four days and did an excellent job. They were professional, detail-oriented, and left the house clean when they were done. We enthusiastically recommend Insulation Alliance. Thank you, Elmer, Umar, and team! ST, Redwood City

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.

The paper should be facing the floor rather than facing outward. See photo.
