TOP QUALITY HOME INSULATION & RADIANT BARRIER SPECIALISTS

After buying my 1950s home one of my first to-dos was getting the insulation up to modern standards. Tom came out to inspect my attic and offered a free estimate to add 10 inches of insulation for a significantly more reasonable price than a competitor I'd looked at, who suggested I needed to remove all existing insulation and blow in new stuff. He and Josh worked quickly and efficiently to get everything installed in my very cramped hard-to-work-in attic, and even helped me fill out the CPS rebate for the cost of materials. Highly recommend!

I recently purchased a 1970s-era home, knowing the insulation wasn’t up to modern recommendations. Using Google, I quickly identified and called 4 of the top-rated insulation companies in SA. The only one who called me back? THE top-rated Geo-Insulation! Better yet, the owner Tom met me at my place that very afternoon.

Tom went up into that attic, showed me exactly what my current situation was, and explained several different solutions. Later that afternoon, he delivered a quote with all of the options available. Pricing was clear and easy to understand. In fact, I’d already done a little research into the pricing and Tom was on the low side of what I expected. Easy choice.

Tom worked around my schedule, came on a Saturday morning with his coworker, and knocked out the install himself. When he was all done, he invited me to look into the attic myself. He’d done exactly what I wanted and what we agreed on. It looked great.

Payment was simple and Tom went the extra mile to fill out the CPS Energy rebate paperwork for me and even credited me for the rebate before submitting the paperwork. He cleared out his equipment, explained the warranty, chatted with me a bit and was on his way.

I look forward to this investment paying me back every month I live in this house. An excellent experience, all-around. ⭐️⭐️⭐️⭐️⭐️

Geo Insulation did an amazing job on my house. I went from less than 4 inches of Insulation to 22 inches. Tom was also great! I financed the project because I'm also getting windows and the financing process was a pain but Tom was great about it. I wish I would have just put it on a credit card to make it easier for him. Anyways he was great. Amazing customer service. Highly recommend!!!

I had Geo Insulation over my house to install insulation and we are satisfied with the results. The house feels more comfortable and the product is also energy efficient.
The owner is very knowledgeable, professional and charismatic.
The installation process was done with minimal disruption to the daily routine.
I recommend this five stars insulation company.

If I could give 1 million stars, then I would… where do I even begin? First Tom, responded so quickly when I asked for a quote- he was so kind and understanding as I had to reschedule about 6 times (our closing date kept getting delayed). Next, he gave prices that were insanely reasonable. When the day came for the insulation blow in, Tom and Josh were right on time, all I had to do was just open the door and they took care of everything else. What I appreciate most was the excellent communication, authenticity, and honesty…. And the stress-free CPS rebate process 👌🏻 (

Geo Insulation did a terrific job on my home today 21 September 2024. Tom and crew were professional, organized and efficient. The communication between Geo Insulation and myself was outstanding, he clearly communicated the process and cost. Additionally, Geo Insulation respected my time and schedule by arriving on time and was completed ahead of schedule. Truly grateful for Geo Insulation; easily the best money spent for home efficiency. Thank you again!

I am very thankful for Tom, his beautiful wife, and the team overall! What I appreciate the most is his communication. I was reading past reviews with 1 star, and this company does not deserve it. He is courteous and respectful and always responds to my inquiries in a timely manner. He will give you the best advice that will fit your project. We had a lot of back and forth - the project took a while because I had a lot of questions as I wanted what’s best for my parent’s house, but he remained very patient and explained why some materials work and some do not, depending on what is suitable for your home. He will make you understand and does not give you the hard sell because he is confident in his workmanship. I tried comparing with other companies and nothing beats their reasonable pricing and work etiquette. He is a veteran, and I will always recommend him! He will surely be on top of my list for future projects to come.
So thank you again, Geo-Insulation!🙂

I found geo insulation based on their reviews. The owner, Tom Porter, was really easy to work with and had excellent communication throughout the entire process. You can tell he cares about educating his customers and doesn’t try to oversell. I had a bid from one other company and Tom beat it by thousands. It only took a week and a half for the entire process from the estimate to the install.

I can’t express my appreciation for Tom and his expertise. You could feel the temperature difference in my home immediately once the job was done. A few hours later and my wife is no longer yelling at me about it being hot in the house.

Tom was very knowledgeable and professional. He and Josh removed all of the old insulation from my attic. Although he was not able to do the spray insulation I was insistent on, he did provide me with two great leads to complete my attic work. Do not hesitate to book with Tom, slots fill up quick! 100% will use his expertise on any future projects. Thanks Tom and Josh for your hard work.

Tom and his guy came out and did an awesome job helping our home stay cool and keep our energy bill down. They were clean, courteous, and did the job on a Sunday to help us make it through a super hot week. Highly Recommend. After seeing how long he was in the super hot attic blowing in insulation, and how dirty, full of fiberglass, sweaty he came out... I am glad that I spent the money and did not try to do this myself. Between the material costs and their costs, it was a HUGE VALUE>!

Thanks Tom.

Tom from Geo Insulation and his team did a great job. He kept me posted on when and what time. Very professional and knowledgeable on what was needed and got it done in a timely manner.
Glad my friend recommended your company.

Geo-Insulation is a great company! All driven by the owner, Tom Porter. Our home is 30+ years old and needed better insulation from the heat. Tom spent the time to thoroughly inspect our crawl spaces - clearly explained what we needed without any “double talk” and quickly followed up with a written estimate.
Tom & Josh did a great job and were very thorough. They stayed focused on completing the job, were very polite and cleaned up before leaving!
We highly recommend Geo-Insulation.

We were very pleased with the service Tom from Geo-Insulation provided. We had thought we needed to pull out all the old insulation, but he told us it was not necessary due to the conditions in the attic. He could have tried to sell us on what we think we needed but saved us quite a bit by offering only what we needed. When they arrived, they put down floor protection and went to work. They worked pretty quietly and quickly and cleaned up after themselves when done. Additionally, they put an insulated, zipped barrier above the attic door for fuel efficiency and cleanliness. Very pleased.

Found Geo-Insulation through Google reviews. Called and received a timely response as T. Porter came and inspected our attic, noted some issues with the duct work and recommended another awesome service in ABC Home & Commercial services for the repair. After the duct work was repaired came back out and completed the insulation job. The whole experience was carried out with utmost professionalism and the price paid was fair according to industry standards. If you need insulation, not only will you get a great service but also education on the best type of insulation to use for your property.

Having owned this 1978 built house for 10 years, the rock wool insulation also from that year….. I said to myself, I can do this I can remove the old and replace with new insulation. And procrastination. Got one quote, and procrastinated more… Finally, after installing new AC and ductwork and it struggling to work….my partner, she had had enough.

She saw the GEO-Insulation truck, and wrote down their number. Being an avid watcher of Google reviews, She looked up GEO and liked what she saw. She scheduled an appointment to get a proposal. From the time, Tom Porter Came to our house to give us a proposal, his professionalism on insulation stood out. Not once has anyone explained to us why We should not use batt Insulation again in an old house and why blown in is recommended.

We decided to go with Geo insulation. Fast forward to installation day, Tom and his worker showed up on time and very quickly and efficiently got blown in insulation into our entire attic in the time promised. Clean, attention to detail. Found spots with no insulation in attic. Took care of that.

And promised a one-year come back in case of need if insulation got disturbed. This is fantastic service.

Geo-Insulation gets my ⭐️⭐️⭐️⭐️⭐️ (5 stars) and I highly recommend them for your insulation needs.

The whole experience with Tom and his team was amazing from the consultation to the insulation removal/installation. Tom gave great insight into what to expect and the benefits of removing the old insulation, which we really wanted and what other companies weren't offering. They also installed attic door insulation covers on both of our attic entrances which is greatly appreciated since one of our access doors is in our primary closet. We had an overall great experience, thank you!

The entire process was great from begining ti end. They took care of all the paperwork and did avgreat job. We felt the difference in the insulation almost immdiately.

Tom and his team were great. Our AC equipment wasn't able to cool adequately during the Summer months which was a big problem with our tenants. We live out of state, but Tom was able to work well with us, offering an affordable price and great service. They completely removed old insulation, de-odorized, air sealed the attic and added new insulation. Our AC is now able to better maintain temperatures inside even when it's 100C outside. Tom also submitted the CPS rebate form on my behalf and overall I'm very pleased with the result. You won't be disappointed.

Tom and his crew were both professional and personable. I highly recommend this team.

Punctual, professional, and very efficient. They did an excellent job and went above and beyond to ensure there was no damage or mess. Highly recommend them to anyone who has insulation needs!

We had a rodent problem in our attic and had to have all the insulation removed. I called three companies for an estimate and was shocked at the wide range of quotes. The highest was $4,200, another $2, 700 and Geo Insulation was $1500. I checked Geo out and found they had very good reviews…almost all were five stars. We hired them and they did a fabulous job! They completed the job in less time than expect and went above and beyond cleaning up and removing a bunch of construction debris. I would recommend Geo Insulation to anyone needing top quality service. The icing on the cake is the owner is a veteran!! Thank you for your service!!

Had insulation installed in the attic at our home. Highly recommend Geo-Insulation

I needed someone to come out quickly for a quote & service for blown insulation before the sale of my home. I had such a hard time finding someone until I called Geo Insulation. Tom walked me through the process & gave me the best quote over the phone. He came out the next day for a quick look & the quote was even lower. I was sold, so he & his team came out the very next day and completed within 2 hours. Thank you Tom & your Team for such a great experience.

Our home was built in the 1950's with a very low pitch roof, so our attic barely qualifies as a crawl-space. Years ago, squirrels and rodents gained access and left a horrible mess to deal with. Other quotes we received to clean out the attic and install a nice, thick, cozy blanket of loose-fill fiberglass were MUCH higher, due to the difficulty of navigating the tight space. Tom with Geo-Insulation was very prompt, professional, accommodating to our schedule, AND provided the most reasonable (lowest) quote!! Tom even filled out the CPS rebate form for me to sign! Josh and his crew were incredible during the work. They were very professional, thorough, answered all my questions, and cleaned up after themselves. Living in the summer heat of San Antonio is going to be so much more comfortable, easier on our energy bills, and less stressful on our HVAC, thanks to Tom, Josh and the crew at Geo-Insulation.

Called 4 different companies and Geo-Insulation was the ONLY one who actually called back! Tom was easy to talk to and helped us get our attic insulation set up and Josh and his crew worked quickly and efficiently. Glad we choose them and would definitely recommend to all who need!!

Tom from Geo-Insulation did a fantastic job with the insulation of my shed. Very professional in his work and completed when said it would be done. Alittle late on my referral but wanted to get it in. Work was accomplished 26 Feb and highly recommended! Thanks again Tom!

If you need any insulation work done, either new build or replacement, Tom is your guy. He calls and shows up when he says he is going to. His staff did some clean up, sanitizer and install on my Mom's home and did it in a very timely manner. It's like of breath of fresh air working with this company. Thanks Tom and staff! Kenny Reyes

Tom and his crew are professional and courteous. The entire attic insulation process was conducted seamlessly. It was a pleasure working with Geo-Insulation. Thank you, Geo-Insulation for a job well done.

Friendly prompt and honest company they blew attic insulation for me and they were in and out

It was very professionally handled, insulation crew showed up on time. I am glad it was a referral from CPS
