    Attic before cleanup

    911 Attic Insulation was the first company that came out to give us an estimate. Max was very professional and had an excellent presentation when he came to give us his estimate. 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.

    I needed a quick turnaround time for attic and crawl space insulation, and 911 attic insulation stayed true to its name. Max was the only one who gave me the next day's appointment among many I reached out to. I told him to consider me as a dummy, and to explain to me the top things I should be doing to add warmth to my newly bought house. He explained everything in detail and at no point tried to oversell anything. He also inspected narrow spaces and did not show the slightest inconvenience in an attempt to charge more for the job because of that. Some others did that, hence pointing it out. He got me a super competitive quote that gave me no reason not to say yes. The highly positive Yelp reviews also helped. On the day of the job, the team arrived on time and was very professional. Ishmael, in particular, communicated effectively throughout. The overall process was a breeze, and I am glad we could get it done before moving in. It is noisy, so I recommend vacating the house for 4-5 hours. They were done earlier than promised, and the quality was excellent throughout. They patched all the vents for rodents and carefully covered the recessed light openings. The droppings were cleared, and the spaces were sprayed. Max showed up a week later with before and after pics and inspected the traps set up. Their warranty covers the material, labor, and rodent protection. Overall, I highly recommend them. They are a hardworking bunch and deserve all the praise and the work coming to them! Good luck Max and team!

    Max of 911attic is honest and transparent. He is knowledgeable and seems to have a lot of experience. We trusted him after getting multiple quotation from other companies. Pricing is very competitive. We glad we went with them. Service is excellent and as described, they fix any issues you may have after inspection of their work. Can't ask for more

    We were planning to replace our roof and attic insulation, and asked 911 attic insulation to give us a quote in January, and Max came over and did a thorough inspection. He did find some traces of animal feces and recommended us to do the insulation after the roof is done. Their quote was very competitive and detailed. After 4 month in May when our roof was done, I contacted him again and he was still able to honor the quote price and offered to clean the space above the garage in the quote as well. He also scheduled the work right away on a Sunday to accommodate our schedule. On the day of work, the crew came in the morning and did a very efficient and thorough work. The attic looks much better, clean and organized. I am pleased with their work and communication was excellent from start to finish.

    Great company! Max thoroughly explained the process and offered great communication, with multiple quotes! Definitely recommend them, competitively priced as well!

    after the full cleanup

    911 Attic Insulation did whole attic cleanup, rodent proof and installed new insulation for my old house. They also replaced all ducts made with very old material. The crew had a hard time as the job happened on the days with a crazy heat wave, feel really sorry for them! Nonetheless, they finished job very diligently and didn't leave any mess. The price was competitive as well. The job happened today so I cannot speak to the energy efficiency and the rodent activity just yet, I will update the review in a few weeks.

    Some before photos

    After gathering 6-7 different quotes servicing South Bay, I chose 911 Attic Insulation because I trusted Max, the project manager who visited my home and provided the initial inspection and quote. His pricing was far more fair than the other companies I've requested quotes from. Max was communicative given his busy schedule, and helped address my questions when they arose through text or call. Day of job: A team of three came to vacuum and clean my attic, sanitize my crawl space and attic, seal and rodent proof, and installed batt 38s. Started around 10 and ended around 2pm. They took pictures (albeit some not too clear or redundant, I do wish there was a more organized system of what they are taking pictures of ex: each corner, center in batches, areas of concern, fixed rodent proofed area, etc.) During the process they had a plastic barrier for the working area (I do wish they were more cautious and attentive to the barrier because it did fall off or they ripped it halfway to do crawlspace and left it open, I had to request it to be taped up again since the wind was blowing in debris from the vacuumed insulation, and eventually the tape lost integrity leaving large gaps to the living room) Overall I thought the team did a fine job. I will recommend them to friends and family and would use them again. I'll have to go up and inspect their work because again the pictures were not the best in highlighting the finer details of the work. Most of the mess was cleaned up, there was still some insulation debris around the area where they had the machine, and some of my plants were stepped on and broken. Not a big deal but I do wish they were more considerate of that. It's a tough job, it gets hot, so I don't blame them at all. I tried my best to provide cold refreshments at various times throughout the day knowing the tough working conditions. Today will be the first test of the new insulation, since weather will be in the low 90s. Excited to feel the difference! What a sad thing to be excited for, but this is life in our 30s I guess :)

They sent someone the next morning for an assessment and got us scheduled right away! In the interim, they gave us recommendations to deter the rats, which worked.

There was an issue with a short circuit because a rat chewed through the insulation that we didn't notice until the weekend, but Carlos responded immediately and came over to fix the issue. We are so grateful to Carlos and the Attic Crew for helping us with rats in the home, helping us feel more confident about keeping them out for the foreseeable years, and for all of their professionalism, knowledge, and expertise!

They worked with us to customize their work to our coastal climate and were very transparent about exactly what materials they would be using (all top of the line, industral-grade!). I have pets and toddlers and they took my concerns about chemical disinfects seriously and offered several options to make sure I was comfortable with what was used in our home. They really seem to take pride in their work and enjoyed sharing before and after pictures to demonstrate all the improvements they made to our crawl space. I could not be happier with my choice to hire them, and plan to work with them again when I'm ready to replace my attic insulation.

Ours was a tricky project because our home is a townhouse that's one unit in a 6-unit building, and we're part of an HOA. Prior to calling Atticali, I had another company come out and do an inspection. They said the only way to solve the problem is to do exclusion work to seal all the places where rats are getting in across the entire building, including entry points on the common roof. But that company would not take the job because they were not insured to work on roofs and also because they didn't want to deal with an HOA. So, I called Atticali based on their good ratings. Irving was our inspector who came out and did a super thorough job of inspecting not only our unit but much of the entire building. I followed him throughout the inspection, which took about 3 hours. Some of my neighbors let Irving inspect their attics, where he showed me evidence of rats in each one of those attics. Irving identified many entry points on the common roof and verified that the only way to solve the problem is to seal all those entry points across the entire roof of the 6 units. I tried to rally my neighbors to have this job done together and properly because we all had rats in our attics and walls. But my neighbors were not interested. I also spoke to my HOA to see if they would cover the cost of the required work on the roof or at least approve this work to be done on our roof, since the HOA is responsible for the roof. (Note that these are one-story units with no access to the attics except for a small attic area above each garage, so the rodent exclusion work had to be done mostly on the roof and exterior.) Atticali was very accommodating and agreed to seal the areas they could in and above our one unit. They also agreed to work with our HOA regarding the required work on the roof. The two men who came did an excellent and thorough job, cleaning up all rat droppings and debris, and sealing all possible entry points. They did miss a bit of clean up, but once I pointed it out to them they cleaned the area very thoroughly. Even though we know it's not the ultimate solution (to have only our one unit addressed) and rats can theoretically get into our unit via our neighbor's unit, we have not seen any evidence of rats inside since then. Thank you Atticali!

We wanted to replace our old insulation because of rat droppings and also improve the temperature difference between our first and second floors, since our upstairs would get much hotter during the summer. Sebastian performed the inspection and was our main point of contact throughout the project. He was thorough, knowledgeable, professional, and easy to work with. The estimate was very fair, and he took the time to answer all of our questions without any pressure. We ended up replacing all of our attic insulation, installing a radiant barrier, replacing some of the ductwork, and adding a moisture barrier in the crawl space. On the day of the installation, a large crew arrived right on time. They did an excellent job protecting our home and keeping everything clean while they worked, and they completed the entire project in a single day. It's been about a month since the work was finished, and we've definitely noticed a difference. Our upstairs no longer gets nearly as hot as it used to, the house holds its temperature better, and our AC seems to run more efficiently. Overall, we had a fantastic experience from start to finish and wouldn't hesitate to recommend EM to anyone looking for attic or crawl space insulation work.

When I told him that I needed someone to clean our dryer vent and what had happened, he said he could come out either between 5:00 and 6:00 pm that evening or the next day. It was already mid-afternoon when I called, so I was surprised to hear him say he could still come out same-day, but I decided to have him do that since I was free and also still a little shaky following what happened with the vent either smoking or steaming. Chris showed up during the window he quoted and wasted no time getting to work. He started the second he arrived and was done within the hour. His pricing was incredibly reasonable and fair and so far, in the couple of weeks since he was here, we've had no issues with the dryer.
