He explained in detail everything that would be done, how long it would take, etc. In my mind, I kept comparing the other technicians from the 3 other companies we contacted for estimates but none of them matched Max's enthusiasm for wanting to win our business. When we finally approved the estimate and scheduled the appointment, Max's team came and finished the job as promised. 911 Attic Insulation's quote was also the most competitive out of the 4 we received. I would not hesitate to recommend 911 Attic Insulation to anyone who is looking to replace their insulation.

My wife is very sensitive to dust and the entry points to the attic were completely sealed off to prevent dust in my home. I am kinda picky and will tell the job was done perfectly. absolutely no dust or mess. 2000 S.F home completed on one day. VERY pleased with the job. I highly recommend this company!!!!

After…read moretalking to several companies on getting quotes and deciding if we wanted blown in or batten insulation. We have approximately 1000 sq feet of attic space and decided on blown in. Met with Jorge who was knowledgeable, friendly and truly wanted us to have a good experience. After getting the quote from them we decided to move forward. The process of signing the contract online and communication via text messages were excellent. They removed all the old insulation, air sealed up the attic in the floor and canned light fixtures, sanitized the attic and rodent proofed. I also needed a bathroom exhaust duct installed, which they did that as well. Our house gets really hot on the 2nd floor, so we opted for the double sided radiant barrier as well in the trusses. R38 was blown in to approximately 13 inches. The team did an excellent job, showed up on time and cleaned up afterwards. This job actually took 2 days, but I would have rather take their time to do great work instead of rushing, so I didn't mind. They also took a bunch of photos along the way and then sent them to me afterwards. After they completed the work, I did notice some nails coming through the ceiling, probably after workers walking on the tresses in the attic and it being an old house. I texted Jorge and he responded right away and arranged for a handyman to come over and fix. Cost was reasonable and average with other quotes I got. I would highly recommend this company.

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.

We have not had any issues since the ones that we dealt with during the initial installation. Fast forward to this week (Mar. 2026).

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

I didn't have the budget back then to do the attic so I only did the crawlspace insulation, cleaning, and rodent proofing. Fast forward to now, I decided to finally get my mom's attic done with another company. When the guy came to check the crawlspace, it was completed by Pro Attic Restoration company but the guy at the time didn't clean it out or vacuum, sanitize, air sealing or rodent proof and only added the insulation. Years later, I am writing this review because it wasn't a thorough job. I shouldn't have to pay another company to finish the job that I had already paid for. On the positive, I do appreciate that they moved a bathroom vent to vent outside so it could be up to code back when they did the crawlspace. That was worth it.

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.

The communication was excellent, even on a holiday weekend I got called back within an hour of reaching out with questions, which I certainly did not expect! They arrived promptly for appointments and were thoughtful about avoiding tracking dirt into our home. They worked with us to customize their work to our coastal climate and were very transparent about exactly what materials they would be using (all top of the line, industral-grade!). I have pets and toddlers and they took my concerns about chemical disinfects seriously and offered several options to make sure I was comfortable with what was used in our home. They really seem to take pride in their work and enjoyed sharing before and after pictures to demonstrate all the improvements they made to our crawl space. I could not be happier with my choice to hire them, and plan to work with them again when I'm ready to replace my attic insulation.
