Jorge and team were exceptional to work with. The removed our old insulation, sealed the attic and added new fiberglass insulation, explained each and every step and went great lengths to do rodent proofing. And all it took was few hours. Jorge also came few months later to fix some of the gaps that the HVAC crew left in our attic. I highly recommend Ideal Attic for your insulation needs. Their price was the lowest as well among all other quotes.
I feel very fortunate to have found Ideal Attic Insulation to work on the attic and crawlspace of our newly purchased home. From the start, Jorge came to provide a free inspection, and he was extremely professional and thorough. He personally went into the attic and crawled into the crawlspace to check every detail. After his inspection, he gave us a very fair estimate with a clearly written and complete scope of work. We also requested quotes from other companies, but it became clear that Ideal Attic Insulation—and especially Jorge—was the most professional, responsible, and knowledgeable. Jorge even helped us connect with other reliable handymen for additional repairs we needed around the house, which we truly appreciated. Once our plumbing repairs were completed, we scheduled the attic and crawlspace work. Jorge’s team handled the attic cleaning, sealing, rodent-proofing and new insulation installation. In the crawlspace, they performed a full cleaning, rodent-proofing, and installed a new vapor barrier. The scheduling was quick, and everything was completed within three days. The workmanship was excellent—clean, organized, and very professional. We really trust Jorge and appreciate his honesty, experience, and dedication. I highly recommend Ideal Attic Insulation to anyone looking for attic or crawlspace services. We will definitely continue using this company in the future. Highly recommended!
Jorge is the best. My wife and I had contacted 4 companies, and by far Ideal Attic Insulation was the winner. With us it wasn't all about price, but quality, knowledge of the trade and experience. We had our old insulation removed when we replaced our roof. Yes, like lot of us when your roof is compromised you have issues with rodents. Once our roof was completed, we set our appointment with Jorge. He came out the following afternoon, and boy was it hot. He inspected our entire attic and came up with a game plan to vacuum and sanitizing our entire attic space. He took a lot of pictures and shared areas of concern with us. We had the roofer's comeback out and tighten up area that may have been able to be compromised. once these areas were tightened up Jorge sent out his crew to install mess wire and stray foam around vent pipes, etc. Jorges recommended we wait a few weeks to install the insulation to see if there were any signs of rodents. After a few weeks and weekly inspections by Jorge and his crew, there were no signs of pests. They installed the insulation, and we could not be happier. We highly recommend Ideal Attic Insulation. Don't waste your time looking for other insulation companies call ideal Attic Insulation and know you made the right decision.

Excellent job, American Attics!! I have met several companies and American Attics was my choice. Mr. Sam Naib, the owner came to the site for detailed explanation and I felt confident that he will deliver what he has promised. On the day of the job, 3 young crew members showed up on time and worked tirelessly the entire time to complete the job on time. There was one minor issue they forgot to do but Sam arranged to fix it in a timely manner. I highly recommend Sam and his team to care for your precious home!!
My old house was extremely inefficient, and after contacting several contractors, I found Sam from American Attics. He scheduled a free inspection and conducted a thorough assessment of my attic. What truly impressed me about Sam was his honesty, attention to detail, and deep knowledge of insulation and home efficiency. Sam and his team replaced the attic insulation, completed rodent proofing, and installed a brand-new air duct system. His crew was professional, hardworking, and respectful throughout the entire process. Just a couple of days after the job was done, I noticed a huge difference-my house feels incredibly comfortable now, and the airflow is much improved. I still can't believe the transformation! I wholeheartedly recommend American Attics for any home insulation, rodent control, or ductwork needs. Thank you, Sam and team, for the amazing work!
5 Stars – Excellent Experience with American Attics I recently had my attic insulated by American Attics, and I couldn’t be happier with the results. From start to finish, the entire experience was smooth and professional. Our home adviser, Sam, was fantastic—friendly, knowledgeable, and very thorough in explaining our options. He made sure we understood every step of the process and helped us feel confident in our decision. The installation crew was efficient, respectful of our space, and left everything clean once the job was done. We’ve already noticed a big improvement in comfort and energy efficiency. If you’re considering attic insulation, I highly recommend American Attics—and be sure to ask for Sam!

Highly recommend this company to anyone looking to have their attic cleaned up and re-insulated. We were dealing with HVAC running constantly and still unable to cool down the house effectively. Oumar visited for an initial inspection and came back with a bunch of photos from the attic. He walked us through all the various options we could benefit from, and left us with a competitive quote, without ever being pushy. On the day of service, Dani and his team were extremely professional in their job. They took care of a bunch of rodent mess in the attic and sealed a lot of rodent entry points. They took care of every small task I asked them to do, and left the whole house cleaner than they started with. Attaching some before and after photos for reference. Even though the HVAC still runs constantly, at least it is able to keep up with the heat and bring temperatures down. Just go for them!
Attic Elite team has done a tremendous job at our place. Looking at the before and after picture clearly justifies the amount of effort they had to put in to get things done. They cleaned up the attic and crawl space really well and worked their way with ducts and insulation in the best possible manner. Omar is really helpful in understanding our needs and gave us the best estimate in market which we couldn't refuse. Highly recommend to consult the team for their best services.
We hired Attic Elite to clean and rodent-proof our church attic, and overall we are very pleased with the experience. Although the crew arrived later than expected, they stayed until the job was done and made sure everything was completed properly. Our attic had been in poor condition for a long time—it was very dirty, dusty, and there were several openings that needed to be sealed. The team worked hard despite the difficult environment. They cleaned thoroughly, removed all the mess, and sealed the holes with care to ensure rodents won’t be able to get back in. It was not an easy project, but they handled it professionally and left the attic in excellent shape. Now our church can use the space with peace of mind, and we really appreciate their effort and attention to detail. Thank you, Attic Elite, for helping us restore and protect our church attic!

We went with Remove, Seal, Sanitize old insulation in effort to identify if there was a Termite swarm. We figured we’d need one day for termite inspection and a separate day for a termite treatment. The day after Attic Pros we had Bongiorno termite inspection come out and he went into the attic and there was no swarm identifiable all clean. Attic Pros did the complete removal and everything was visible and clean. It was cold at night and we didn’t wanna wait for our pre-scheduled couple of days out so I contacted Attic Pros and they came out the next day. Three guys installedR38. Bats without paper backer minimizing mold- they did an excellent job. All of our light was sealed. The hatch got new layer of bubble wrap insulation. The Attic vents had chutes installed allowing fresh air interchange. Can feel the difference- absolutely a warmer house. Thank you Attic Pros. Also Attic Prod had low cost to many other HVAC companies that just farm it out to subcontractors. Highly recommend Attic Pros.
I was able to self schedule an appointment within 2 days. Rabi was very professional and clearly communicated both the issue and the plan for resolution. They were able to complete the work within a few days. Their price was competitive. The team arrived between 10 am and worked all day to clean my attic, close all access points, and install the new insulation. They worked all day until 6 pm. They were very pleasant, answered my questions, explained things well. The process was pretty quiet so I was able to work at my remote job while they worked. They left everything clean in the crawlspace and took all garbage with them. I did not enjoy having creatures in the attic but they made the process of getting rid of them as pleasant as possible.
This is an excellent Company: They are professional, caring and thorough in their work. They took before and after pictures which was a great help. They removed rats, mold, asbestos from the attic. They removed the installation and replaced it with new. They sealed areas where the rats could have entered. They set traps and so far no sign of rats. They left my house clean. I have confidently referred you to my neighbors. Thank you.

How businesses conduct themselves when no one is looking is important. I was on my way to class and saw this man bring in someone who needed some food. The man in need ask if he could get a particular item and without hesitation the Insul-tech worker replied yes. I love this! You have some amazing people working for you Insul-Tech, I hope you appreciate them.
Absolutely thrilled with the service I received from insul-tech! From start to finish, they were professional, knowledgeable, and incredibly helpful. I wasn’t entirely sure which type of insulation would be best for my home, but their team took the time to walk me through all the options. They explained the pros and cons of spray foam versus mineral wool in a way that was clear and easy to understand, and they helped me make an informed decision based on my priorities—energy efficiency, soundproofing, and long-term value. In the end, we decided on spray foam for one specific vaulted room that needed maximum airtight sealing and mineral wool for the rest of the house for its sound insulation qualities. The spray foam was then backed up pink stuff as hybrid system to save cost. It was the perfect combination and I’ve already noticed a huge difference in comfort. The sound dampening of rock-wool is unbelievable! You can’t hear construction from one end of the house to the other. This will help keep things quiet while the kids are sleeping. Very happy with that choice. The installation itself was seamless, clean, efficient, and right on schedule. The team showed up on time, treated my home with respect, and left everything spotless. I couldn’t be happier with the results. Highly recommend insul-techs to anyone looking for top quality insulation, outstanding customer service and most importantly guidance on where to use different types of products.
We have an older model gas fire place that needed to be serviced and got the run around from the store we bought it from about getting service. I'm so glad we ended up connecting with Insul-Techs, they came out promptly, serviced our unit and fixed the issues we were having. The communication from the scheduler to the folks who came out to service was excellent and I would highly recommend them to anyone.

I recently had Atticare come out to clean and insulate both my attic and crawlspace, and I can’t say enough good things about the experience! Sean was my technician — super friendly, on time, and clearly knew his stuff. He showed me photos before and after, explained everything in plain English, and made sure I understood exactly what was being done.
I recently had Atticare come out to my house last year to remove old insulation and then lay down new insulation along with rodent proofing the attic. A little over a year later Rats were still getting into my Attic and even though my warranty had expired Attic care was nice enough to send out their engineer Kyle to address the issue. Kyle spent several hours at my house today to do a thorough inspection and rodent proofing of any access areas were the rats might be getting into my attic. Kyle also repaired my air ducts the rats were chewing, cleaned up the attic of any droppings and completely sanitized. Very happy with the follow up work Kyle was able to complete today.
I recently used Atticare for my home in Pasadena, and I can honestly say it was one of the best home service experiences I’ve ever had. The team showed up right on time, explained the process in detail, and got to work right away. They removed the old insulation, cleaned and sanitized the attic, and installed fresh insulation that made my home feel instantly more comfortable. What impressed me most was how thorough and professional they were. They didn’t just do the job—they also sealed entry points and made sure my attic was protected for the long term. It’s such a relief to know my home is cleaner, safer, and more energy efficient. I highly recommend Atticare 5 stars all the way!
