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.

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.

Very professional jobs. Fast and clean. Attic cleaned and sealed. Then sprayed new insulation. Huge difference. Recommended.
Atticali did our R-38 spray foam insulation. From the free estimate to the pre-visit and installation, everyone at atticali was on-time, professional, and respectful. They were very quick to reply over text, email, or phone if there were any questions and communication was super clear. It was great working with them and will work with again when the time comes.
Isaac from Atticali was very professional and worked with us until the end of an infestation problem. We are grateful for his committment through the process.
