The four other companies I called had someone come out and give me ridiculous high pricing and barely explained what insulation is best for my attic and WHY!!! The crew, Juan and his assistant, came out and cleaned everything out! Jose and Richard came out the next day on time, installed blown in insulation in 2 hours. They were quick, super clean, and friendly. They even took pictures before and after. I'm happy I found this company. The price saved me around $2000 compared to the other quotes I got. I enjoyed talking with Cynthia and Emi in the office. I will call them again for my walls next year after a few more projects I got to take care of. Highly recommend!

Terrible experience with this company. The original invoice they sent me was for $1,060. Cynthia…read morein their front office called me six weeks after the work was performed and told me I owed an additional $424 for a radiant barrier they never completed. When I said my invoice was paid in full previously and that I needed to see an invoice showing me what she was saying, she hung up and created a new invoice showing I owed an additional $630. I paid the invoice but when I sent the company all of the correspondence showing their mistake and asking for a refund for the overpayments they ignored me. There are hundreds of insulation companies in LA. Stay away from this one. I have all the images and voicemails saved if anyone wants to see them. Please don't use this company.

My bedrooms on the second floor of my townhouse had become really hot in the evenings. I decided…read moreto add more insulation to see if that would help. A gf had it done years ago and said it did make a difference in her house. After researching info on Consumer Reports and AI, I started interviewing companies and getting quotes. When I called Insulation Nation I could tell Dustin knew his stuff and had integrity. His quote was very fair and much less than the first one I received from another vendor who acted surprised that I knew what a R rating was. Dustin recommended a radiant barrier on the inside of the roof to help keep the attic cooler. I had not seen that mentioned in my research, nor from the other company, but eagerly said YES! Anything to keep cooler. From the first call with Dustin until the job was completed, everything was top notch. Communication was great. They texted their eta and arrived on time. The crew was clean, polite, friendly and professional. They took before, during and after photos. Aldo showed them to me when they were done to ensure I was happy with their work and to answer any questions I might have had. Their work was excellent. They paid attention to every detail sealing any air leaks I had-which were several. If only other companies were this professional and easy to work with. I very highly recommend Insulation Nation.

He sent a bunch of very informative reading material to help me make an informed decision on what I wanted. The project took a while to get started because I was scheduling other house work and Dustin waited patiently. In fact, he provided some really good advice and got me in touch with other vendors. The job went smoothly and painless. The foreman Aldo checked in with me to let me know what's gonna happen. The crew did a great job taping things off to contain the mess. They answered all the questions I had during the job. Prices are competitive. The quotes are detailed so you know what's gonna happen. And they send pics of the work afterwards. Really enjoyed this whole process with them. Totally recommend them to anyone.

Even though we didn't end up moving forward, I would absolutely recommend giving Dominic a call if you're looking for someone honest and professional.

A few of the places I checked with didn't want to give a rough estimate, but none of the them lied about their reasoning, so they didn't get reviews. Some even gave me a rough estimate right here on yelp. Based on some of the other reviews, it seems like this sort of pressured sales approach is their business model, instead of helpful answers and good work.

This was the lowest bidder by maybe 10% and did OK work, but I had to check their work then request…read morecorrections, and they were unclear on scope options so I was left with unsealed fixtures and fiberglass debris in the house to clean up myself. While they did work with me, did exceed expectations in rodent proofing patch support, and were quite friendly and ready to correct most shortcomings I pointed out, I would have preferred they not rely on my oversight to give quality work consistent with my original direction. They did not tape off a sealed plastic tunnel from the front door to the attic, did not let me know sealing off light fixtures was excluded, left some spotty gaps between batts of insulation and between batts and joists and did not run a second layer of insulation where I had requested it perpendicular to the first layer to better air seal joist gaps. They were unclear about IC-rated lights in contact with fiberglass batting insulation and its fire risk and did not seem to know the code on attic ventilation requirements enough to answer questions fans or vent sufficiency. Granted, I did not have insulation removal as part of the scope, it was already done by a prior contractor during rodent proofing. Instead of making a tunnel, they taped off a small space from the attic hatch to the floor and put construction paper down on the floor. This helped with scuffs to the floor and may have contained some of the fiberglass dust/particles, but did not protect from scuffs on the wall or contain the fiberglass during transit to the door that was shed from the new batts being carried in or from their clothes and shoes, even though they generally had only one person trafficking the batts up to the hatch. They bagged up debris in the attic and carried batts in bags in from the door. They removed all the paper and plastic before I was done with my inspection, an inspection that yielded more work required, then they didn't put protection back for the short time of rework. The foot traffic left some fiberglass flakes and particles strewn about the floor. It took me two hours of cleanup to get that debris fully clean so my baby could crawl on the floor again. I vacuumed with a shop vac, made three passes with a swifter dry duster, and vacuumed with a house vac. I suggest asking them during the bid stage about the following, getting a quote for that work (with optional line items if you don't need everything), and confirming it is written in the proposal/bid/work order scope before awarding the project: - a sealed tunnel for transport of removal and installation - cleanup with vacuums and swiffer after until no particles remain in house on floors or touch surfaces - air-sealing fixtures and other gaps from rooms below - code and safety insulation contact with fixtures and blocking with gaps (2"-3"?) to avoid contact - insulation contact with rafters/roof battens/sheathing - roof ventilation adequacy and fan install if needed - gap prevention - running a second layer of batts perpendicular to the base layer for better air sealing - minor or major rodent proofing gap sealing with mesh and foam This is a good list to consider for any contractor you use, some contractors may find this obvious or already include it, but you could still benefit from knowing what to check for and avoiding change orders. I ultimately was satisfied by the work and they made some corrections and concessions to balance the expectations vs delivered result, but would have been happier with more clarity of scope options (too late to seal the fixtures now unless I pay $600 more or do it myself) and I had to do lots of cleanup that I could have avoided if I simply rejected their suggested home debits containment method of bagging with no tunnel. Although I would not suggest this crew if you are not prepared to check their work, which not everyone is physically capable of doing in tight spaces of some attics.

On the day of the job, they discovered my attic was much larger than originally quoted. Even so, Daniel honored his original quote, and I truly appreciated his honesty and integrity. The team was professional, thorough, and kept me informed throughout the entire process. They provided photos after vacuuming out the old insulation, after sanitizing and sealing the attic, and after completing the installation, so I knew exactly what was done every step of the way. Daniel delivered everything he promised, even though the actual job was significantly larger than expected. It's rare to find a contractor who stands by their word the way he did. I'm extremely happy with the quality of the work, the excellent communication, and the outstanding customer service. I wouldn't hesitate to recommend Belmont Insulation to anyone looking for an honest and reliable insulation company.

O.J. Insulation just completed a sizable job at my personal residence that included installing foil…read moreradiant barrier in (4) separate attics between my house and guest house. I have a black composite roof, so the attic temperature was reaching over 130 degrees on hot days. Since the installation of the radiant barrier, I'm already experiencing a temperature reduction of just over 20 degrees. To confirm that, I have (5) window gables that aren't directly over living space and thus didn't require the installation of a radiant barrier to those sections. Now I can easily monitor the temperature difference with (2) quality digital thermometers and confirm the difference between the untreated gable areas and the treated primary attic spaces that are directly above my homes living area. This is a remarkable difference. My ceilings are no longer radiating heat into my home like they were before (even with the R19 ceiling insulation and gable vent fans that were originally installed). My air conditioning units and ducting, which are in the attic are no longer struggling to keep up due to extreme attic temperatures and now running less often to keep my home cool. Now let me talk about my experience with O.J. Insulation. First, I called (3) companies that stated online that they install radiant barriers. The other two companies both made appointments but didn't show-up or call to reschedule. O.J.'s estimator (Paul) made the appointment, confirmed the appointment the day before and showed-up on time. He was thorough with his inspection and suggested the best approach to achieve the attic cooling goal I was looking for. A week later a (3) man crew spent an entire 3-days working in my attics, which at the time reached temperatures of 120 degrees (I don't know how they were able to work in those conditions). The entire crew was polite, courteous, and extremely hard workers. My wife even made lunch for them every day because we were so appreciative of what they were doing for us. I highly recommend O.J. Insulation. Their service is excellent and their prices are very reasonable.
