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.

Idan does not disappoint! This is our second time using his services, and this time I went straight to him without even shopping around. His team is responsive, efficient, and highly professional. A major bonus is their expertise with home insurance systems, which made that part of the process effortless for us. Later, despite a dispute over the scope of work (which was due to a miscommunication, not his fault), he stood by his word and honored his promises, even when it resulted in a significant financial loss for him. His integrity, particularly in that situation, is truly commendable!
After experiencing a roof leak that led to multiple issues, I interviewed several companies before ultimately choosing Leader Restoration, and I’m so glad I did. From start to finish, the process was smooth and professional. I worked closely with project manager Idan, who was knowledgeable, responsive, and easy to work with. Leader Restoration handled everything seamlessly—including coordinating with my hygienist for the final mold inspection, which we passed on the first try. Their expertise in mold remediation and dedication to quality restoration services truly stood out. I couldn’t be happier with the results and highly recommend them to anyone facing water or mold issues.
We discovered mold during our home remodel and contacted Leader Restoration. Idan, the project manager, was incredibly professional, and Julio, the lead technician, did excellent work. The mold remediation process was smooth, the price was competitive, and we got clearance in less than a week. Highly recommend them for reliable mold removal and restoration services!

As a contractor you're always looking for the best supplier of insulation, someone who can provide you with competitive prices, hardwood and quality. Vortex insulation is the best option! Their office manager Mike made everything so easy and the owner Luis and his team installed it all right away and perfect. These guys are the best insulation company in the whole Bay Area!
These guys are the best! Extremely quick service and a true dedication to their customers. I had a complicated request about exposed beams and they worked nights and weekends to make my vision come to life and stick to their original date. Would recommend them 5,000%. Great value, great quality, great service!

We recommend this company for any insulation needs. Overall experience was good. Customer service at all levels was excellent. We give this company 10 plus stars.

The Bay Area Insulation (Miguel’s) and team have done three jobs for me now, and I couldn’t be happier with the results. Each time, they’ve been professional, friendly, and really easy to work with. Their prices are fair and competitive, and the quality of their work speaks for itself. It’s rare to find a company that’s this consistent, but they’ve earned my trust and future business. Highly recommend!
Mike came to my house took measure and next day he and his crew started the job; hard workers they did a great job
As a general contractor, I would highly recommend The Bay Area Insulation. Miguel and his team are reliable, respectful and work well with my team. I would highly recommend them.

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!

Insul-Techs were hired to insulate my house. The scope of work involved insulating my walls, attic, and crawl space. The team installed different R value fiberglass insulation in the attic, walls, and crawlspace. They also installed spray foam insulation in one of my vaulted ceilings as shown in the pictures. I also got my garage walls insulated so that I can use that as a gym year round. They did an amazing job and after they were done with the insulation, we felt the difference on how cooler the house felt even when it was really hot outside Chris helped us with the scheduling and was a delight to work with. They are a hard working team who catered to all our requests and did everything to ensure we were satisfied with the job before they were done. Thank you Insul-Techs!
I was referred to insultech from a respected contractor. Luis came by for an estimate. During the inspection i was given options on the types of insulation and the insulation factor of each method. After further review of other insulation companies non were as professional in explaining the process or the materials used, and most of all they were much more expensive for the same work being chosen. The techs came in completed the job with the utmost respect for property. Communication with Luis and the front office was effortless and the response was done in a timely fashion. The insulation factor coupled with the mini split for cooling. What a difference. Customer satisfaction comes first. Great job InsulTech.
I recently had Insult Techs replace the insulation in my home, and they did a phenomenal job! The difference it made was immediate and noticeable. Their customer service was excellent from start to finish, and their pricing was very competitive compared to other companies I looked at. Luis and his crew were professional, efficient, and respectful throughout the entire process. It was truly a great experience, and I highly recommend Insult Techs to anyone needing insulation work done.
