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.

They were quick, efficient, and professional, and very communicative. On the second workday, we received a text from the owner saying that his team hit traffic and would be about ten minutes late.

They even finished about half a day early. I've already recommended Atticity to several of my neighbors. I'll be calling them again if I ever need more insulation work.

I was so pleasantly surprised that George the owner came out for the inspection himself. All the other companies sent sales people out that really did not know their business. Ideal had the best price by far for a better product. I had the work done on 6-6-26. The crew arrived on time, and on point. 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.

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.

My house had literally zero insulation in the walls and I was hesitant to add any due to mixed reviews, but I trusted Joseph and he delivered. Now I don't hear as much noise and the rooms feel a lot warmer. Then he did the attic by first cleaning it, then sealing it and filling it up to spec with quality insulation. My house used to have cold spots and heater would kick on every 20 minutes. Now there are no cold spots and the house stays warmer a lot longer and again much quieter from external noise. I would highly recommend his services.

What stood out from other companies I interviewed was Francisco took very detailed before photos when giving the estimate from all different angles of my mom's attic versus other companies barely looking at it just taking just one or two photos. I knew if he was thorough on the initial interaction, he would be thorough on the job. Here's what I really liked: - No sales pitches, scare tactics, high pressure sales tactics. He was very transparent and wasn't pushy. - communicated very well throughout the process - His team also cleaned out an outdoor storage closet for me which had never been cleaned. - Hardworking crew that were extremely detail oriented. - In 2022, I hired an insulation company to just do the crawlspace and apparently while they laid the insulation they didn't vacuum and rat proof and air seal like the contractor stated in my agreed contract so Francisco came in to do the work the last company didn't do. - before and after pics were shown and it's like night and day - Francisco's team also let me know they didn't see any termites issues which makes me feel better because I thought I had to tent the house - They notified me of a split piece of wood in the attic that I need to fix with a handyman. I had also seen this in the before photos he took. Look no further, this is THE one. There's many companies that do this type of work, but Francisco was very easy to work with and patient in answering my questions or concerns. Hardworking crew.
