If you're seriously considering Attic Masters, make sure that at the very least you get a second opinion, because here was my experience: Their technician, Sebastian, came out and did an inspection that, for reasons beyond my understanding, didn't include actually looking at our second attic space. Yet, he still included it in the estimate and priced it as a 1k sq ft job and called for removal and replacement of all the insulation. He recommended replacing all the ducting as well. The problem? Each of the four subsequent inspections I received noted that the space was small (less than a couple hundred sq ft) and clean with no issues. While he did inspect our primary attic space, he claimed that rats had gotten into the ducting and recommended that it all be replaced. Guess what? Each of the subsequent inspections noted that the ducting was in great shape, but just needed some outer insulation repair. Before I brought these issues to Attic Masters, I had a conversation with the Adam mentioned in other reviews and had the same experience those reviewers did where he was defensive and made it very difficult for me to get a word in. And, I emphasize - this was before I even brought up any issues! After I brought the above mentioned issues to their attention in a subsequent email? No apologies or acknowledgement of the obvious problems. They just tried to brush it all aside. I'm sure they have their reasons, explanations, and justification, but it sure seems like they were being dishonest with me. You have a lot of options when it comes to this work. Proceed at your own risk. read more

This is the very first time I'm giving less than 5 stars for a yelp review. I usually like to give companies 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. read more

We used Attic Masters in 2015 for an insulation job. They installed blow-in insulation in the attic and bat insulation in the crawl spaces. We have not had any issues since the ones that we dealt with during the initial installation. Fast forward to this week (Mar. 2026). We are in the process of getting quotes for installing a vapor barrier. During inspections, two separate insulation experts notified me that the batt insulation was installed incorrectly. The paper should be facing the floor rather than facing outward. See photo. read more

We've now hired Attic Masters for two different properties. The first in San Ramon that we were converting into a rental and now another smaller unit in Milpitas. Both times the experience has been excellent. Like a lot of people, we kept putting this project off after Covid. At some point, though, you realize this isn't a DIY job and you need profs who know what they're doing. From start to finish, they made the process easy. They came in, removed all the old insulation, sanitized the attic, and installed brand-new insulation with zero hassle. Each job took just a couple of days: day one for removal and cleaning, day two for installing the replacement. Both times the crews worked efficiently and left the spaces as clean as could be expected. It is costly but not as costly as doing it yourself or ignoring a real problem. read more

Recently went home to visit my mom and she was complaining about the house getting too hot. Remembering how those SJ summers go, I know how blistering they can be since we don't get that ocean breeze. I also know that we haven't done anything to our attic in a long time. I found Attic Masters here on yelp and saw people I know used them as well so I decided to give them a shot. I called them up and set an appointment. The team was on time, polite, and explained everything clearly before they began. They took out all the old insulation and cleaned up the attic thoroughly, sealed up air leaks, and installed the new insulation. They also took care of some of the issues found with the ductwork. The crew was pretty proficient with their work. We love an optimal job. After all was said and done we noticed a difference immediately. The house is cooler during the day and theres less dust floating around. Our HVAC system isn't working so hard either so hoping to save some money on the bill there. Definitely recommend using Attic Masters as their pricing is fair, the work is professional, and my moms happy. Thanks guys! read more

Good price. The guy coming over is polite and patient. Nice follow up. Would recommend.

After a bad leak in our roof from heavy rains, we needed to replace a portion of insulation. Thankfully we did not need to replace it entirely! Highly recommend Attic Masters! read more

Needed this for another place I had since again We had a major attic issue with heat and mice, and after calling a few companies, I remember working with them before Attic Masters and they were fantastic from the start nothing has changed. . The team was responsive, professional, and knew exactly what they were doing. They gave us a clear quote within minutes and followed up promptly with options for scheduling. They even made the process feel easy and stress-free. It's my go to whenever needed for attic work done right! read more

Recently I had my spray in insulation replaced by Attic Masters, I couldn't be happier with their services. From the my 1st call to the completion of the job, the team was professional & friendly. They took the time to explain what to expect and answer my questions. Having noticed positive improvements since replacing the old spray in insulation we are pleased. Thank-you for the great job! I recommend Attic Masters to anyone needing attic work. read more

We had our air ducts cleaned! I'm very happy with the work that was done! The pricing and length of time needed to complete the job matched the quote. I would recommend them to anyone needing this service! read more

Attic masters scheduled asbestos abatement and replaced the insulation and ducts at my home. I had a tight schedule but they were able to accommodate me on short notice. They made sure no dust got into other areas of the house by sealing thoroughly. In addition to insulation replacement, they also did a thorough job of rodent proofing the house. Throughout the process, they answered all the questions I had. read more

Attic Masters just completed a job on my daughter's home. Their quote was the best we received - by quite a bit. They did a great job. They went to great lengths to protect the living spaces and contents and did a perfect clean up when the job was done. My daughter is looking forward to a much more comfortable home. Thanks Ruben and crew! read more

My family's home has been going through renovations for almost a year now and we recently needed to get new insulation in our attic and a thorough cleaning. I searched on Yelp and found several businesses and companies and requested a quote from all of them. Only a few got back to me including Evergreen Attic Installation. They called me within an hour and was incredibly friendly on the phone. Since I live in San Jose, it was easy for them to come by and look at our attic. After several recommendations and estimates, we got our attic cleaned up and insulation work began. Workers were very friendly and worked well with our busy work schedules. They also kept the work areas clean and protected our floors, furniture and our belongings. My family is really happy with the attic's new insulation and how clean it is. Our house was built in the 1970s and I don't think anything was ever done to the attic ever since. Now, the attic is very clean and any potential hazardous materials and dust and mold were all removed. We are really happy with the work and would recommend Evergreen Attic Insulation for your attic's needs. read more

Attic Masters insulated our attic yesterday. Our home is 70 years old, and still had the original sawdust insulation installed. Attic Masters' crew came and removed all the old insulation along with assorted debris from the past decades, sanitized the space, air sealed all the cracks, did some rodent-proofing, and installed new insulation. We got several quotes when planning this work, and chose this company because the gentleman that came to do the estimate did such a good job explaining the work they would do, giving us options where it made sense to do so (insulate above the attic? What type of insulation?) and being transparent about the whole process. We were not disappointed, the work was beautifully and quickly done. Would highly recommend their work. read more

Attic Masters - Insulation and attic fan. - Insulation Installation Near Me

I got 5 proposals. Decided on Evergreen and I wasn't disappointed. Professional crew, great clean work on our attic and we barely felt that they're working in the house. I can't say enough good things about their work ethics! Best thing is that we feel big difference in the temperature in our home on hot summer days. It stays a lot cooler inside (without turning on the AC) so it feel like a great investment and energy efficiency improvement. If you're thinking about it, do it! read more

I made an appointment for an estimate to get my attic insulated with these people a week ago (June 25) via the Yelp app online. "Adam" communicated with me that they would be here between 10AM and 12PM on July 2nd. I had to shuffle some appointments I had in the morning around to accommodate for this time. Well, fast forward to today (July 2nd)...I've been sitting on my butt all morning to wait for the estimator to show up. When 12:15PM rolled around, a total classic no-show. I called their office and "Adam" (I presume the same Adam I was talking with through Yelp?) acknowledged my appointment and said someone would be calling me right back... So about 20 minutes later, someone named "Reuben" called me and said, "the office made a mistake...I might be able to make it around 2.." I told him "no" as I have to be in San Francisco for an appointment at 2:30..he sounded like a broken record and kept repeating that the "office made a mistake.." I told him to just forget it, that I was going to go with another company that genuinely respected their customers and their time..(do they think people just sit around all day, that other people's time is not important?!) If you're going to flake on an estimate for a potential job, chances are high that you'll flake on the actual work, too! read more

Attic Masters - Adam TOTALLY flaked on me... - Insulation Installation Near Me

Attic Masters (San Jose) exceeded my expectations on response time both for the estimate and the installation. The team was very professional and protected my home and garage from the dust. They predicted they would finish around 5 and they were done at 5:30. They took many photos of the before and after attic space and provided them to me. Quality of work is excellent and cost was exactly as quoted. read more

When the day got cold, little critters started to build their homes in my attic. Following the reviews here, we contacted AtticMaster for an inspection. Roy was our inspector and later led the clean-up team. He is professional and easy to work with. He came for a free inspection the next day and actually came back the second time since we forgot to ask for the garage attic inspection at first. The pricing was reasonable and the scheduling was easy and quick. On the day of clean-up, Roy brought a four-men team including himself. The team moved fast and finished the work in 7 hours. Throughout the day, Roy texted me with progress update and photos. Overall the work was satisfactory. I am glad to have AtticMaster to clean out our attic. A good company with hard-working and professional people. I highly recommend them. read more

Company is highly recommended. Workers arrived on time and perform their job in a professional manner. Although the job took longer than the workers or I expected, they stayed and completed the installation the exact same day. I contacted Evergreen to clean out the air ducts at two adjacent houses and noticed how much pride the workers put into their work that I also paid to have them wrap the ducts. While the workers were wrapping the ducts, they observed that I had a flea infestation festering in the basement. I recognized that there was a pest problem coming from somewhere around the properties but wasn't exactly sure where. Thank you....now I need to locate a good exterminator! read more

From beginning to end my experience with Attic Masters was top notch! Ruben came to my home for the inspection and quote; he was on-time, knowledgable and courteous. Interactions with the office for quoting, invoicing and payment were smooth and hassle free. We opted to have the attic and crawl space over hauled (Thoroughly cleaned and sealed along with new insulation and ducting installed). We were quoted 2 days work which is what they delivered. Let me tell you that Ruben and crew are the hardest working folks on the planet! The amount of material moved out and into the attic and crawl space was unbelievable! They arrived on-time everyday, sealed off the work area and always cleaned up after themselves. Ruben also identified a number of issues with our AC system, proposed and accomplished the repairs while not impacting the original timeline. Net results are simply amazing, the AC is barely running now even on the hottest days. When it does you can tell that it is working so much more efficiently. Great eye on the job service! Thank you Attic Masters, it is a pleasure to write you a quality review to match your quality service. Cheers! read more

This place is very professional from start to finish. Looked at 3 different companies before we finally decided that choosing Attic Masters was a "no-brainer" type deal. Quick turn around time for responding as well as a detailed estimate on their insulation service. Spoke to Jonathon, who was our estimator, and he was very professional. Being that it is winter and all, we definitely wanted to get things done before the weather starts to freeze our butts off. Attic masters were very clean and efficient and our "go to" person in our insulation project. It's not always easy to find a reputable business in such a short amount of time let alone having a newborn crying in your ear while trying to finish things up, but we were very glad we went with Attic Masters. Clean, detailed, and professional. Thanks guys! read more

I was in need for insulation services for my home, and searched on Yelp for local companies. I found Attic Masters, and wrote an online inquiry from their website link provided from Yelp. Within 15 minutes, I received a phone call from a live person to ask about my insulation needs. I was able to receive an estimate online, had some communication for fine-tuning the estimate, and scheduled an appointment. When the attic professionals arrived (Roy, and two other team members), they were very careful about preparing the entry way to my attics (I have two). I appreciated that they were very clean in their work, and respected my home. I originally wanted to have insulation only, but also opted to have the attic cleaned, decontaminated, and varmint-proofed prior. It seemed to make sense to have a fresh, new space before adding new R38. The cleaning work done by Attic Masters was amazing. They found a lot of debris, unwanted material, rat droppings, and more. I have posted before and after images to better describe how meticulous their work is. Not only was I unaware of the disgusting condition in my attic, I now have a greater peace of mind knowing that above my head is a sanitary space. When the cleaning was done, I was able to take a look for myself - the attic literally looks brand new! I would highly recommend this service to anyone, and especially for homes that were built many years ago like mine. The installation of the R38 was a great choice. I have added images as well for those interested in doing this. You can see that they carefully packed the R38 edge to edge. There are no areas where there is not coverage. Currently in December our energy bill is over $400. I am confident this will drop significantly now. Overall, I am very pleased with the service, staff, and work performed. The end to end experience with Attic Masters was very professional. If you are in the market for attic cleaning, decontamination, or insulation upgrades, I highly recommend them. read more

I have used Yelp for years, but this is my first review and it could not be more deserving. The attic in my 1971-built house had little or no remaining blown-in insulation. When a new roof was installed a few months ago, the attic became so hot in the afternoons that the AC ran continuously until almost midnight. So that is where Attic Masters came into the picture to replace the old insulation with new R-30 battens. They also added a radiant barrier and replaced the return HVAC ducts with new insulated ones. The Attic Masters lead, Reuben, and his team of 4 installers did a fantastic job. They worked long days in my hot attic and their workmanship was outstanding. Moreover, they were the most polite professional team ever. They finished in three days and kept me informed of their progress along the way. I highly recommend Attic Masters for any insulation or HVAC duct work. read more

We called AtticMasters a couple of weeks ago and the company scheduled our bid promptly. Jonathan was presentable and knowledgable. He not only gave us a competitive bid, but also answered all my questions and concerns. After we shopped around, I felt even more comfortable with his bid and scheduled the project. He showed up as scheduled and made sure our living room was covered very well as I have little kids. I also requested to get the job done in one day instead of two and he made sure to bring extra people to assure that. During the final walk through, I pointed at a few minor things and asked them to be tidied up. He gracefully addressed those. Overall, Jonathan and his crew did a very good job for us from the bidding till the insulation itself. We highly recommend them. read more

I have been planning on cleaning out my attic for a while now, but I ALWAYS put it off because my attic is filled with rodents, and its so dirty and I am absolutely terrified to go up there. I actually want my attic nice, and clean and insulated. I was searching for a company to help, and I called Evergreen Attic Insulation, and they were EXTREMELY nice over the phone. They quoted me very fast, and the price was very good and fair. They came out to my house, and were so friendly, and they understood exactly what I wanted, even though I barely knew what was going on in my attic, since I hardly go up there since I am so scared too. They removed all the rodents, and they also insulated my attic. Now, I am so happy to use my attic for storage, and its so clean. They were super fast, and efficient. The price was super good in my opinion. I will for sure be calling them back if I need help. I highly recommend them to everyone! Thank you! read more

Requested a quote around March 2020 for removal, cleaning, sealing, and installation of R38 insulation. Then the pandemic hit. I put everything on pause until further notice. In December my daughter and grandkids who had been living with us moved into their first home and I thought this would be a good time to reconnect with Evergreen. I contacted them from my original quote and asked if there any adjustments considering the time that had passed and if they were available for a service call. They asked if I had made any changes to the home that might effect the quote and after saying no they held to the same quote as provided almost a year prior. The day of the appointment I asked to have them delay their start time because of an unexpected circumstance and they didn't hesitate to comply. Upon arrival they set up by taping all fabric covered furnishings with plastic to prevent contamination of the old fiberglass insulation. Everything went smoothly. In addition to the new insulation they also installed a thermostatically controlled gable vent at no additional charge. I was provided photos of the work that had been accomplished. No complaints. read more

After my roof replacement, the chaotic attic space needs a fresh clean up and update with insulation and air duct replacements. Attic Master came out very reasonably quoted with clearly itemized costings. I've also requested to have a new air duct added to the sun room which turned out to be quite a bit of works. Attic Master has been very accommodating in my schedule change requests. On the first day, they arrive promptly and have all the old material removed. Installation with R38 fiberglass and a mixed of R-6 and R-8 flexible air ducts took about a day and a half to complete. The job overall is well done. There's some mishaps during the process. But, the owner took the time to have it mitigated. That response earn my respect to his professionalism and worthy of my recommendation to those who are looking for a reliable contractor for attic related works. read more

Had Attic Masters come in to help remove all our attic insulation! Got a quote here on YELP. We scheduled a time and they got it completed. They did a great job with the new installation. Timely and responsive!! Thank you. read more

Ruben and his team did a fantastic job replacing the insulation in our home. We needed to do some electrical rewiring in the attic, which meant we needed to remove the insulation, get that electrical work done by a separate contractor, and then install new insulation at a later date. Evergreen was very helpful and professional in coordinating that schedule and Ruben and his team worked diligently to clean out the attic, seal the entire house to prevents rodents. They also took pictures of all their work so it was easy for us to review it. After the electrical work was done, they came back and did a very thorough job insulating the attic, again documenting everything with photographs. They are a hard working, considerate, professional team. I recommend them highly. read more

Truthfully.. this place is awesome. I had no idea who to call, where to call, and what to look for when it came to getting my attic cleaned up. A friend referred me to Evergreen Attic Insulation and I can honestly say These guys are the real deal, they were prompt, understanding, and respectful. They explained the process and price breakdowns of the service I needed for my attic and were more than flexible with my price bracket! Highly recommend and thanks again!!! I can finally go into my attic without a full body protection suit on LOL. read more

My work needed some insulation service and cleaning and I was tasked with finding a company that would perform this job. I had previously used Evergreen Air Duct at my last job but was looking for one closer to my area. I had found Attic Masters online and reached out to them and was able to get a quote and appointment without any hassle. Once appointment day came around, I had walked into my office and already saw the staff unloading their vehicle and starting to work. Big plus that they had got there early! This was ideal since we have a warehouse portion of our facility and it was a lot of ground to cover. Not to mention, I have no idea when we last had this done to our office building. I was surprised that the noise of the work did not seem intrusive and that all the material and hardware was set up nicely as to not get in the way of common walkways. By late afternoon, I was notified that the job was complete and was given a quick walk through of the services performed and any issues that came up along the way. Service was done, payments were taken care of, and both parties were satisfied. Do not hesitate to contact them if your attic needs work! read more

ROY is your guy. He is honest, detail oriented and no hassle. I had 4 companies estimate and every single one bothered me with unnecessary comments and phone calls.

AtticMasters Review: 5 Stars. The BEST!! Here's the scoop: Two things happened at our home after the recent rain storms: Water damage and a rodent infestation in the attic. A leaky roof, combined with rats seeking shelter turned our attic into a complete disaster. We did a quick look and found torn insulation, water damage and obvious rat's nests and droppings everywhere. The smell was disgusting. We posted a request for a recommendation on our local homeowner's association website (NextDoor.com) and got a great review for AtticMasters. When I did get around to calling they gave me a quote over the phone and almost immediately followed up with an email copy of the quote. I was particularly impressed with their professional attitude. On the phone, the receptionist was poised, direct and spoke with perfect grammar - very refreshing. We were given a choice of appointment dates working around our schedule and it was a snap to find a day and time that worked for everyone. The project folks confirmed the day before and we even got a call from the Project Manager, Jonathan, about 30 minutes before they arrived. Once Jonathan and his team arrived, they went straight to work. No hesitation. I was impressed with the efficiency of the team - working both in- and out of the attic. Almost a immediately we had a steady stream of debris, droppings, rotten insulation and even a few dead rats coming out of the attic...while at the same time new insulation, new vent covers and roof patching materials going in. Very efficient team. As a bonus they even went around the attic and filled all the entrances that rats could get into and even though I though I had closed things up pretty well they found quite a few I missed. We'll still have to have some roof work done on the outside, but the obvious water leaks were fixed on the spot using a special rubber sealant which was more than sufficient for the tiny leaks they found. Finally, the team pretty much cleaned up the whole area leading into and out of the attic - even to the point of a quick damp mop along the whole hallway. In summary, these guys nailed it. The attic looks clean, neat and squared away and it actually smells like any other room in the house now. Amazing. If you have attic issues, and want a team that knows what they're doing, then these are the guys. 5 Stars! read more

Michael was Amazing in his work, he was on time, courteous , hard working and very polite! I haven't seen this type of person and service in a long time! He was meticulous in his work and cleaned up each area like he wasn't even there. I would highly recommend him for any duct cleaning service that is needed. His manager should feel privileged to have a worker like him! Thank you Michael for a truly wonderful job! read more
