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.

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.

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.

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.
