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.

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 cannot say enough good things about Attic Pros! From start to finish, it was a great experience…read more We initially called for attic, crawl space and duct cleaning, as well as rodent proofing (sealing vents, etc). Samim came out and did a very thorough evaluation, showing us dozens of photos of areas that needed attention. He also recommended new insulation, which we hadn't considered and told us our dryer vent needed repair. It took us a few weeks to schedule, during which time Samim followed up periodically, never pushy, always answering our questions and providing more info. His professionalism and knowledge was a huge reason why we chose to work with Attic Pros. On the day of the job, Osman and crew cleaned the attic and crawl space and installed new installation, while Douglas repaired the dryer vent and Kevin cleaned the ducts. They did an amazing job sealing off the work areas and keeping the house clean, despite it being very messy and grueling work! They spent about 3 hours vacuuming the attic and another half a day sweeping the crawl space by hand. Their attention to detail was above and beyond what we expected. We were sooo impressed! And Samim's recommendations were spot on - our dryer is much more efficient now and we noticed the house was cooler within hours of the new insulation being installed (it was the height of summer). We'd use and recommend them again and again!

From the very start of my engagement with Attic Bros it has been fantastic! I found them in a…read moresearch on Yelp and no joke, my 8 year old calls me Bro, so figured I would fit right in with the Attic Bros! I think within maybe 20 minutes of submitting my Yelp quote I had a call back and an appointment. Michael came out and did a THOROUGH inspection of the attic took a ton of before pics. But not only that he then sat down with me and went through the entire process, which is quite frankly, amazing. He also answered all of my questions and offered some input on my ducts. He made himself available for any other questions too, which was so nice since my husband wasn't around - there's always another question. With this process, not only do you get your old attic crud sucked out, they look for and seal any entry point for critters. They add mesh from the inside plus they go around the whole perimeter from the outside of the house too just to make sure they caught all entry points. They seal all air gaps from things like recessed lights and fans. And then they sanitize. Something about knowing my 70 year old house got a deep clean is VERY satisfying for my OCD cleaning tendencies. The insulation went in - they use a batting that is 12" thick, my attic before probably had an inch, maybe 2 in spots of the old blow-in stuff which was just dust and dirt and disgusting. This batting is eco-friendly - no pink artificial coloring, just the insulation which also is no longer harmful. Night one and I already saw a difference. Usually when it gets cold at night by 2:00 am our home temp inside drops, we stayed a steady temperature throughout the night, I might be a bit crazy, but it feels like there's a sound dampening effect too - I don't have to have the TV on as high of a volume. Follow-up, they add traps and will come back to monitor in a couple weeks to make sure there is no activity. Another over the top customer service layer - we had Jordan as our project/site manager for the day - I was texted by the system with his picture, LOVE this feature, its really helpful. And he called when he was closer. He kept me updated throughout the day and was just really kind, very professional and the crew he brought, Jesse and I did not catch the other gentleman's name - they worked so incredibly hard, and efficiently. We really appreciated this crew, they were amazing. If you are hesitating for any reason to get your insulation in your attic done - DON'T - it is 100000000% worth every dollar, which by the way is an incredible value when you really think about what it does for your home. I am quite mad at myself for not doing it sooner, but certain things had to happen first, so here we are! I would choose Attic Bros in a heartbeat and whole heartedly recommend them!

Chris came out early on a Saturday morning to meet me and inspect my attic. He provided a free estimate, according to my availability, not his which I greatly appreciated. When the crew came out they were on time and very professional and courteous. I would also like to add that it was A very hot day yet, they took their time and did not try to rush or take any short cuts. They sealed off everything in the work area and did a very thorough clean up after the work was done. I feel I was given a very fair estimate and even with my job being so small, they still spent most of the day onsite. If you suspect you have a rodent issue in your attic, I recommend Atticare.
