    highly highly recommend! Very happy with Attic Masters from start to finish. They were kind enough to give me a rough quote without an appointment for us to understand if this project scope was even within our budget. all the others gave me the run around and im sure it's because they wanted to "upsell" based on whatever they tried to see at our house, and I did not have time to entertain that. Realizing what we wanted we waited a little to save more and immediately contacted them back to have them write a formal quote. We chose to go with them because of their honesty and prices were comparable, but to have people in your house all day, this was the crew we trusted. Could not have been more right with my gut, the crew blocked off the hall to keep the mess at bay, did a great cleanout and we even chose to add on plywood for a small area to have extra storage. VERY happy with this company and crew. Look no further.

    Attic Masters did a great job with our attic. They sent Juan and his crew and they were respectful, professional, and efficient. The rate was very reasonable among the 3 quotes I got. I highly recommend. Attached are photos of before and after photos.

    Juan at Attic Masters gave me a super competitive price for insulation work, and the price was very reasonable. Note: Beware of the various crooks out there who charge way too much! So,.. Attic Masters showed up at my Anaheim home in October 2023 ready to go at 9am. Workers were extremely polite and professional. They laid down plastic on the flooring so that debris would be contained. They cleaned out all the old insulation, vacuumed, and sealed all gaps and rodent proofed before laying down R-38 Owens Corning Pink Panther fiberglass batting. They took a multiple pictures during the different stages, and they were done by 2pm. My wife and I were so extremely satisfied with the work, that we had them work on a rental property we own in Pasadena. Again, the price was hard to resist! Unfortunately it was getting into late November and the roof needed to be replaced first. So Juan waited until December before we scheduled a date. Unfortunately they couldn't get Pink Panther from the suppliers, so they offered R-38 Johns Manville (Berkshire Hathaway) fiberglass batting as a substitute. It turned out to be a better deal I felt. Again the service was excellent, and the work was finished the same day. I highly recommend this company. They are very hard workers and will address any concerns you have and give you the very best quality work! It's a great value for your money!

    After receiving a crazy-high estimate from another company for basic spray-in insulation, we contacted Juan with Attic Masters. He gave us a quote several thousand dollars cheaper than the other company. Juan's quote also included removing our old insulation, sanitizing, and filling cracks and crevices. The other company made no mention of these services. Two days later, Juan and his four man crew completed the job. The insulation provided was CertainTeed R38 roll-in. Juan and his crew were professional and efficient. Once the job was complete, they thoroughly cleaned everything up including vacuuming our hallway and living room. The attic looks amazing and we are quite satisfied.

    I had attic masters suck out my blown insulation and insulate with new r 38 insulation. Otni and his crew were great, they exceeded expectations. The attic access was inside my home, they put down plastic and left the place cleaner than it was when they showed up. I've been procrastinating doing this upgrade but I'm very happy I did it, I highly recommend attic masters.

    Plastic Sheeting
    Jayson Z.

    Absolutely impressed by the work done by Attic Masters as well as how quick they were. Only one day to clean and vacuum out the rockwool in my entire 1959 house attic and then disinfect it, followed by another day to install new ductwork and R38 insulation. Juan was very communicative and always put up plastic sheeting to protect my hallway and floors while they were here working. I highly recommend their services, especially if you still have the old stuff in your attic.

The first quoted me an absolutely ridiculous price that would have cost an arm and a leg. The second guy offered to do it for cheap but he couldn't figure out the issue so he just disappeared and never showed up. Kevin and Milo came in and had to clean up the mess left by the previous contractor, then thoroughly tested all the zoning, dampers, and zoning board to actually diagnose what was going on. Not only did they figure out the real issue, they fixed everything completely and at a very fair price. On top of that, Kevin noticed my thermostat wasn't functioning properly and replaced it on the spot, explaining exactly why it was causing problems. Kevin is extremely knowledgeable and clearly knows this stuff inside and out, but what I really appreciated was how he explained everything in a way that actually made sense. No pressure, no sales pitch -- just honest options, estimated costs, and pros and cons for each path forward. And a huge cherry on top: they cleaned up extremely well afterward. Given the mess that had been left behind before, this really stood out to me. Everything was left neat and organized, and they made sure the area looked better than when they arrived. That level of professionalism and respect for your home goes a long way. Kevin is also just a genuinely great, friendly guy -- the kind of person you actually trust in your home (and honestly, the kind of guy you'd grab a beer with). Milo was also professional, efficient, and clearly knew what he was doing. Together, they were an awesome team. After this experience, I will absolutely be using J Martin for all of my HVAC needs going forward. Huge thank you to Kevin and Milo for turning a stressful situation into such a positive experience. Highly, highly recommend J Martin Indoor Air Quality!!!

They took our problems seriously but didn't take advantage and press extra services on us that weren't necessary. We especially liked how knowledgeable the inspector was and how patient he was with our questions. They did a beautiful and very professional job cleaning out the space, air sealing, and doing the exclusion. After discovering that our attic was improperly ventilated and had been accumulating mold for several years, we hired them again to the do the clean out and mold remediation up there. Again, their work was on point for price, extremely professional, and beautifully done. Everyone we worked and talked with, from the inspector (Brennen), the onsite crew, the office, and even the owner, were friendly, well-informed, professional, and prompt. After the work was completed, they have been prompt about following up with inspections to help us stay in warranty on the work and ensure no future issues. We have recommended this company to neighbors with similar issues in their homes.

The extra steps taking to secure any openings aside from the attic were greatly appreciated. I would recommend to others.

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.

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.
