Spray Foam Insulation in San Diego, CA

Attic Heroes put insulation in my attic, and I had them come back about a year later to encapsulate my crawl space. They were communicative, they offered a very reasonable price relative to some other quotes I got, and they did solid work. I recommend them for both attic and crawlspace work! I'll also say that compared to some other companies I got quotes from, they were far less pushy and salesy. I had a different company make it seem like my whole house was about to come apart at the seams if I didn't sign up for all their (very overpriced) services, but Attic Heroes did none of that. Their pricing and recommendations seemed very practical and fair.

Attic Heroes installed insulation, a vent smart fan, and replaced air ducts, all at a great price. The technicians were fast and clean up was excellent. Fidel even replaced my attic lid which was previously damaged. In all, the service was great!

Attic Heroes was great to work with. The employees took care every step of the way and show great pride in their work. From the first meeting with the knowledgeable sales person to the respectful and meticulous cleaners/installers, I couldn't be more happy. The price was reasonable and the work was executed quickly!

Big shout out to Green Faith for coming out to do my attic. Real friendly guys, give it to you straight and were able to get me a good deal and do the job the same day. Was happy I went with them.

Erik and Philip were very knowledgeable, courteous and got my project finished the same day. My existing insulation was original from the 90s, so it definitely needed an upgrade. Highly recommend!!

Philip and Erik came to my home the same day I called. They were very thorough answering my questions and they were able to do the job of blowing in excellent quality insulation into my attic space the same day. Already the house feels much more comfortable. I am so glad that I found this BBB accredited company that exhibits integrity in dealing with customers.

They were friendly,efficient and did an outstanding job

Excellent services👌🏻highly recommended

We hired High Performance Attic Insulation after our HVAC contractor said our system was struggling due to poor attic conditions. The difference their work made is astonishing. They didn't just add insulation; they performed a comprehensive air seal, installed a radiant barrier, and upgraded our ventilation to modern standards. The crew was incredibly professional and meticulous. Our home now reaches and maintains the desired temperature effortlessly, and our energy bills have dropped significantly. This is true high-performance work.

They were prompt and were professional! Job was done fast and accurately to my needs! Would recommend them to anyone. Thanks again guys for the awesome job!

Definitely recommend! Great customer service and quality work. All done in a timely manner. Thank you !

Great experience! Hands down i'd give these guy's 10 stars if it was possible! They were fast and reasonable. Answered all my questions and i had a lot! I'd recommend them to anyone needing insulation

I had Quiet Home Insulation upgrade the insulation in my attic, and the difference is amazing. The house is quieter and holds temperature way better now. The team was on time, professional, and cleaned up after themselves. Definitely worth it—highly recommend if you're in San Diego.

I’m really impressed with the quality. Hands down one of the best insulation homes there is.

Good home service

Had my blown- in cellulose attic insulation done by Advanced Insulation System. Victor and Tiger did a really great job. They took special care to keep my house clean by laying paper runners and hanging plastic sheeting. Everything was explained well and Victor showed me the final result which looked great and was professionally done. Looking forward to enjoying a warmer and cooler house. I would recommend this company.

Advanced insulation system did an amazing job. The staff were punctual, kind, respectful and considerate. There was a tiny hole in our ceiling and an employee (I wish I remembered his name - Marco?) repaired it for us. Victor and Tiger are amazing workers, worked so hard and very respectful- I would recommend this company to anyone and everyone. The staff are incredible and the final job was perfect. Thank you.

Hunberto, Juan, & Eddie were great. They kept the job site tidy and did high quality drywall on my old, 1950 plaster home. Will definitely go back if I have future insulation/drywall needs.

These professionals did a fantastic job on our older home. We were concerned about both energy loss and indoor air quality. Evergreen San Diego Insulation addressed our attic and crawl space, using materials they explained were better for the environment and for our family. The crew was meticulous, clean, and took great care in sealing air leaks first. The house feels more solid, comfortable, and we have peace of mind knowing the job was done right with quality products.

Outstanding service and results. Living in San Diego, we wanted a company that understood the balance between keeping heat out and retaining warmth on cooler nights. Evergreen's team provided a perfectly tailored solution. They were punctual, knowledgeable, and their workmanship is excellent. Our energy bills have already started to reflect the improved efficiency, and the overall comfort of our home has increased dramatically. A reliable and highly effective local business.

I contacted Evergreen San Diego Insulation after struggling with high cooling bills and uneven temperatures throughout our home. Their energy auditor was punctual, thorough, and took time to explain exactly where our home was losing conditioned air. He used an infrared camera to show me the problem areas clearly. The installation crew arrived on schedule, worked efficiently, and cleaned up every speck of dust. Our home is consistently comfortable now and our AC cycles far less often. Professional, knowledgeable, and fair priced.

We had a fantastic experience. After another contractor gave a one-size-fits-all quote, San Diego Thermal Insulation provided a detailed, science-based assessment. Their crew was prompt, professional, and worked with great focus. They emphasized the balance between insulation, ventilation, and air sealing, which has made all the difference. The results speak for themselves: a more comfortable, efficient, and quieter home. This company does things the right way, with integrity and local expertise.

I am thoroughly impressed with the quality of work and customer care. San Diego Thermal Insulation provided a customized solution for our complex attic with multiple roof levels. Their crew was skilled, patient, and ensured every cavity and eave was properly insulated and sealed. The before-and-after difference is night and day. Our home retains warmth on cool nights and resists heat during the day far more effectively. A trustworthy and highly skilled company.

Outstanding service from a company that truly understands San Diego's unique temperature swings. From the initial consultation, their knowledge of both coastal and inland microclimates was evident. They provided a clear, fair plan and executed it flawlessly. The installation team was punctual, respectful, and their workmanship is top-notch. Our home is now consistently comfortable day and night, and we've already noticed a decrease in our cooling costs. Highly recommend this knowledgeable local team.

We hired Thermal Nest to solve the constant battle with temperature in our older San Diego home. Their approach was incredibly thorough—they didn't just add insulation, but performed a complete assessment that included air sealing and evaluating our attic ventilation. The crew was professional, efficient, and left the worksite immaculate. The difference is remarkable; our home now maintains a consistent, comfortable temperature naturally, with far less reliance on the HVAC system. They truly built us a better thermal nest.

I am thoroughly impressed with the quality of work and customer care. Thermal Nest provided a comprehensive plan for our new construction project, ensuring it was optimized for efficiency from the start. Their crew was skilled, coordinated seamlessly with our builder, and their attention to detail was exceptional. The home performs beautifully, staying comfortable with minimal energy use. This proactive approach gave us incredible peace of mind. A trustworthy and forward-thinking company.

You'll get excellent service from these folks. Fast, easy service with quick turn around times. Super affordable, too.

Happy I called this company. So helpful and knowledgeable. They were able to answer all my questions and worries. You should try them out.

Great company and I couldn’t give enough praise for the job well done. They were very helpful along every step of the way. Give these guys a shot you won’t be disappointed.

I was inspired by trusted San Diego insulation company they are the best team I have ever worked with. I recommend

San Diego is a trusted roofing company. I got more than the service I paid for

We had our attic serviced with CA Attic and Build in Dec. around 1100sqft. Attic was cleaned out, sprayed, insulated and sealed to prevent future rodents from getting in. The attic hadn’t been touched since it was built. They did a great job and cost was reasonable for the amount of work. But what impressed me the most, was the customer service after they were done. Attic and Build doesn’t just do the job and disappear. They follow through with their commitments. Really a great company. Thank you owner Ben, Dan, the kind receptionists and the installers at CA Attic and Build.

I highly recommend California Attic and Build for your next attic project. They offer free attic inspection and illustrate well about their steps of old installation removal, cleaning, sanitizing, sealing and insulation reinstallation by pre-recorded video clips. I was offered $5000 for the approximately 850 sqft attic project with a 10% discount at the end of the inspection. This is my first time contracting a house project. Without other homework, I accepted the offer on the inspection work shown by the picture and video I received from the inspection. On the day of the work, four young workers arrived on time, set up the work environment that prevented dirt pollution of the house on their work path from the street, through one bedroom window to the attic. They proceeded to work following the steps. By noon time, the lead of the four informed me that sanitizing and sealing was completed and they would start the new installation after a brief break for lunch. They returned to work shortly afterwards and completed the blown in the latest CA code cellulose installation around 2pm. A few days later, I received an email from California Attic and Build with the invoice and the pictures of the attic that show the work in progress to completion, nice work! I particularly appreciate their caring customer service, clear communications and extra effort to address my extra requests.

Rats are gone – and so is the stress! California Attic & Build did an amazing job getting rid of the rats in our attic. From the first inspection to the final walkthrough, they were professional, knowledgeable, and thorough. They sealed up every entry point, cleaned and sanitized the attic, and made sure the problem was fully taken care of. Communication was clear the whole way through, and they genuinely cared about making sure our home was safe and rodent-free. Highly recommend them if you want the job done right the first time!

I love this Compamy!!! So easy to work with Nate had excellent knowledge and really explained things well. When crew came 4 of them Chris came to the door introduced himself and they started Chris was excellent in running the guys and keeping me informed even my dog loved them.!! I highly recommend them they have great follow up as well!!

Just had my attic cleared, cleaned, and insulated by Attic Construction. The crew did a great job - they were prompt, professional, and quick! They first covered up the floors and walls with plastic to protect and keep them clean. They removed the old insulation using a giant vacuum. Next, they sanitized the attic and finally, installed a thick layer of new insulation. The process was much easier, quicker, and cleaner than I had anticipated.

This company is great! I called because my house was way to hot in the summer and my feet would freeze in the winter. My free estate was done by Adam. He called with his arrival time and was very polite and professional during his visit. I was impressed with the services provided like clean up, rodent proofing and sanitation, and the R value that they offered. My appointment was scheduled for a few days later on the spot. The work crew was just as professional and thorough. They worked till they were done on a very hot day and all the employees are very happy friendly people. I would recommend them to anyone. Also they have a one year warranty on the rodent proofing and was told to call if I hear anything. GREAT WORK! Very affordable! Thanks!

We had a very good experience from start to finish with Attic Projects. I chose this company based on significant research and was not disappointed. Paul made me feel very assured with my choices, and went above and beyond to help correct a few issues that inevitably come up through the construction process. I recently had a roof replaced, and Attic Projects did a complete clean, seal and sanitize, checked the electrics in the roof, identified and installed missing ducting, and installed a radiant barrier. Very competitive, price wise, and very good customer service. Brandon in the office was also great, as was the installation team: Jesse, Eduardo, and Aaron.

I just had a service from Attic Projects Company to remove the old insulation of my Attic, prepare for rodent control and new installation of cellulose and R38 fiberglass batt to my Attic. Paul Lang is a highly professional and knowledgeable project manager who did an outstanding job managing my attic insulation and rodent control project. From the very beginning, he impressed me with his detailed inspection—he took thorough pictures of the problem areas, clearly explained the issues, and offered well-thought-out recommendations along with a transparent breakdown of the costs for each phase of the project. Paul was able to provide me with a very reasonable quote. Brandon followed up promptly to coordinate Phase I and Phase II based on Paul’s assessment. The crew stuck closely to the agreed-upon schedule to complete the work. Jessie and his team members Eduardo and Noah were responsible, courteous, and took great care throughout each step of the process. The entire team worked seamlessly together, and their planning ensured the job was done efficiently and effectively. It took a day to remove the old insulation, clean up the area and work on rodent control process, took half day to complete the installation of cellulose and some fiberglass batt after it passed QC on rodent treatment. They also showed great respect for my home by laying down rugs on the floor and stairs and installing plastic sheeting to protect the surrounding areas. The team was not only professional but also very friendly and easy to work with. I highly recommend Paul Lang and his team for anyone needing attic insulation or rodent control services. Their attention to detail, clear communication, and quality of work were top-notch.

We made the right choice when using Attic Projects to reinsulate our attic! We were particularly impressed with their policy to wait a couple of days after cleaning out the old insulation and rat proofing the attic to make sure the rat problem was eliminated. Having a quality control inspection right before the new insulation was put in, let us know that this job was being taken care of correctly. Every person we made contact with at Attic Projects were knowledgable and friendly. They answered every question and always made sure we understood their answers. Highly recommend Mathew and his team at Attic Projects!
