    Air gap sealed
    Aurelio E.

    When you buy an old house, it's bound to have issues. In my case one of my issues was the lack of insulation in the attic. When my house was built in 1962 insulation wasn't a requirement like it is today. I didn't want to go through another winter in a cold house so I requested a quote on yelp from multiple businesses. Rafael from High Grade Insulation Services was quick to give me a call. During our initial conversation, Rafael asked a few questions and gave me his professional insight on why my house was so cold. After I interviewed three businesses, I decided to choose High Grade Insulation Services (HGIS) for my project. The price was very competitive and Rafael was very personable and informative. Rafael showed up on time and was in communication with me days before our appointment date. The estimate given was the actual price paid. All the air gaps were sealed with foam and 10" on blow insulation installed. Plastic was put down in the areas where the work was happening, and they cleaned up everything before they left. Rafael was even nice enough to replace some screens in my attic that had rusted away at no cost, in order to keep the critter out. Overall, I'm very satisfied with the job High Grade Insulation Services did. I like to support small local businesses when I can, and in this case I'd do it again. As a matter of fact, next month I'm going to have HGIS insulate my crawl space if needed... old house problems. I'll write a second review when that happens. Give em a call. Great company.

    Finished Batt Insulation in Attic

    Rafael responded speedily to my inquiry on Yelp. He was professional and scheduled an estimate in reasonable time. I received 3 estimates, his quote was competitive. He responded to my questions about different options and did not bs around. Scheduling was most important to me as I wanted to get this project done before Christmas and his crew availability matched my working schedule. After the weekend came around, he communicated with me early in the morning on the day the work was going to get done, his crew showed up, and did the work efficiently: set-up, install, clean-up and were out the door in 2-3 hours. I am very happy with the results.

    Batt insulation near attic fan...

    Rafael called back right away after my inquiry. I had quotes from him in under 24 hours with all my options. Pricing was very fair. He's very easy to communicate with. His crew was on time and the job was done in under a day, including the attic fan. I'm already saving a small fortune on my heating bill! His guys, Eduardo and Danny, were very respectful of the property and eager to do a good job. Rafael checked in throughout the day to make sure we were on track. This was probably the best contractor experience we've had in recent years. Thanks, gentlemen!

    Rafael and his crew were extremely professional and did a clean job insulating my walls and attic in the garage. He was careful while drilling into closed walls to not cause damage. They also cleaned up the area very well once they were finished. For the best pricing and great service, I would recommend him, without a doubt.

    New insulation!
    Lindsey M.

    I had several estimates before choosing to go with high grade. They sealed my attic, installed new insulation, sanitized, and rodent-proofed my attic. The team was super nice, efficient, responsive, and Raphael went out of his way to call me later that evening to let me know that the ducting for my whole house fan was pinched (and sent me a video showing me what he was talking about). Excellent pricing. They weren't my lowest bid, but very glad to have used them and would highly recommend!

    Highly recommend these guys. I received quotes and spoke with a handful of the major Insulatuon companies that have over a hundred reviews and I'm glad that I worked with Rafael and his team instead. From the start, these guys were great communicators, answered all my questions, were fast and easy to schedule, and provided a very competitive price quote. After deciding to work with them, they were very accommodating to book a time that worked for me, communicated easily via text and phone call, and arrived on time. They also did great work with prepping my house with plastic, worked in a highly organized and clean manner, and did a great job insulating my low crawls space attic. These guys are great and I'm glad that I found them.

He even took the initiative to repair a vent that had been left broken and unattached by a previous company (before we had even committed to moving forward!) On the day of service, Dominic called ahead with an estimated time of arrival, which was greatly appreciated. Tyler, Patrick and Mike arrived right on time and immediately began preparing the space with floor protection and plastic sheeting to contain any dust or debris. As someone who works from home, I also appreciated how quiet they were throughout the process. They provided progress updates with photos along the way, and the results were impressive--everything looked clean and well-finished. Tyler also shared images showing that they had corrected and properly sealed ductwork that had previously been patched with duct tape by another company. They completed the job well before I expected it would be done and then cleaned up and left the place spotless! Overall, a highly professional and very detail-oriented team. We had an attic restoration done previously, and the differences in the 2 companies were night and day. I would not hesitate to go with Attic Advisor again, highly recommended, 100/10 stars

    I don't usually write reviews, but my experience with Thermal Advantage and Brody truly stood out…read more Contractor interactions often end in frustration, so when someone delivers exceptional service, it's worth sharing. Brody was flexible with my limited availability, arrived on time, communicated clearly, and completed the entire job on my 1,300 sq ft home in just four hours. He and his apprentice Luke worked efficiently and quietly, protected the work areas, and left everything spotless. Brody also used a thermal imaging camera to confirm each wall cavity was properly filled, which gave me a lot of confidence in the workmanship. The results exceeded my expectations. The patched holes are barely noticeable--I was prepared for my walls to look like a cheese board, but they look great. Brody was honest, fairly priced, and delivered excellent service from start to finish. The insulation product itself impressed me as well. As a façade engineer, I understand the value of insulation, but I didn't expect to feel such a dramatic difference so quickly. Within hours, the heat inside my 1945 home dropped noticeably, making it far more comfortable during peak sun.

Brody communicated clearly throughout the entire process and delivered outstanding quality work. Brody and Evgenii were very respectful of our home and did an amazing job cleaning up after the foam insulation was inserted into our exterior walls. We especially appreciated their willingness to address our questions. Our family has noticed that foam insulation has made our home warmer and reduced the outside noise. We are looking forward in making our home more engery efficient and also saving money on our electric bill. We would highly recommend Thermal Advantage of California to anyone looking to drastically improve the insulation of their home.

    Short Review: Great work/value and genuinely exceptional…read morecustomer service. Matan, Tony, and his team did an amazing job on my attic. The attic work itself was perfect. What they impressed me most was how they went above and beyond whenever an unexpected issue came up. Catching a hidden leaking pipe to helping me find a plumber within the hour, fixing and painting my attic door, and coming back promptly to address an airflow issue, they consistently made me feel like they truly cared about my home. I'm extremely happy with the service (I'd give /5) and would highly recommend them! Long Review: I reached out initially to cancel when I decided on another quote. That's when Matan reached out to me and asked if he could stop by ASAP. His initial evaluation was very clear as well as his recommendations. He explained all the details very clearly with visual examples as well (booklet, video). For my 820 sq ft small attic (3-4 ft tall), his quote was the best compared to 3 other companies that I had reached out to for the amount of work done. I received the quote immediately after Matan left my place. Matan and his team (led by Tony) completed the home prep, hepa filter, insulation removal/vacuuming, roden proofing, air sealing, sanitizing, R44 blown in insulation (15"), air duct repair, and pulled up air ducts where applicable. They also recommended installing junctions for the open wires they found in the attic, which was a fire hazard. There is a lifetime warranty on the insulation, a year warranty on the repair work, and a 3 year warranty on the rodent proofing! During the visit, Tony + the team were prompt and finished all the hard work in one working day (9am-5pm) When all the insulation was out, Tony told me that there was a corroded water pipe that was leaking occasionally. I assure you That definitely would not have been caught by me... Matan then helped me look for a same-day plumber (within the hour the issue was found) who was able to fix the pipe. He also helped fixed my attic door that was broken and even painted it for me. Tony and his team then finished the work after plumber finished. I really appreciated their hard work, attention to detail, especially in the smaller attic. After work was done/a day later, I had mentioned an issue to Matan that I wasn't feeling any air in the house and that I couldn't hear any airflow. I thought maybe the insulation is that good Actually, it was not the fault of his team or anyone. there was a missed hole in my cassette style air handler in the ceiling where the insulation was getting through. This holes has been there since the house was made so again I want to say it was very easy to miss and nobody's fault. Immediately after reporting the issue, Matan came by to clean the air handler blower wheel and fixed the two holes with wire mesh and expanding foam sealer. This issue would've never been caught without the help of his teams. He did this during his very busy schedule, and made accommodations for me. He also even fixed the air handler door for me as the door seems to be wet. After that fix, he stayed to test the air flow is good and we could hear the airflow again. I hope what you take away from the review is: - Matan and his team really care and pay attention to detail. Not only that, if there's any issues, they will promptly do anything to fix it ASAP. There were so many small details (leaking pipe, broken attic door, air handler door, holes in air handler box on sealing, getting a plumber within the hour) that they helped me solve. Matan kept reassuring me that "I got you" and it is 100% true. I am extremely happy with the service and how they showed up for me more than just the minimum effort. Thank you Matan, Tony, and the team for taking care of me and my place!
