Our Reviews
Here are just some of the nice things that our customers have to say about us.
- 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!!Michael Bond5/07/2023brian gray5/05/2023I 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.SR Hernandez5/04/2023Our 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.Lito Bujanda-Moore4/27/2023Called 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!!frankie martinez3/25/2023
- 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 Reyeskenny reyes3/05/2023Tom 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.Susan Robb3/05/2023Richard Rocha3/04/2023It was very professionally handled, insulation crew showed up on time. I am glad it was a referral from CPSjavier smith2/26/2023Excellent professional attic insulation performed by Geo-Insulation, LLC. Our living areas feel a lot warmer and comfortable with the 14 inches of fresh insulation. Tom (Owner) and crew were punctual, organized and performed a walked through before and after the project. Not only did Geo-Insulation keep us informed through out the project, but also repaired an attic vent screen and provided guidance on how to process rebate paperwork required for the electric company. We should have called Tom and his crew long ago. Highly recommend Geo-Insulation for all your insulation needs in and around the San Antonio, TX area.Mr. Rico2/26/2023
- Tom at Geo-Insulation was great to work with his team did an excellent job quickly and efficiently. I would not hesitate recommended this company.Don Hardy2/03/2023The owner, Tom, visited with us and inspected our current insulation and showed us what adding more insulation would do for us. It was clear that our home was about 25 yo and a lot of the settling had occurred was thin due to its age. He also explained that other remedies might help but would not be as good if there was insulation deficiency. He helped us with access for the insulation and added insulation to the garage area that also provided better attic storage. He was very easy to work with and due to some circumstances we had to change installation dates. When every thing was ready, his crew started on time and finished perfect cleanup! The crew was very professional, courteous, and happy to work with us. Tom inspected the job and he even filed a rebate claim form with CPS. We are very pleased with our experience with Geo and highly recommend Tom's help and kindness. J. ColemanPreston Coleman2/02/2023My parents used your services and were very happy with the job that was done thank you from the ColemansJoanna Faleide2/02/2023Great company to work with. On time and on budget! The owner Tom personally came out and checked out the job and got everything lined out for the job. His guys worked very fast and efficiently and cleaned up like they were never there before they left. Definitely a major difference with the attic insulation and can especially tell with this cold front that just came in. Helped with the paperwork for my CPS rebate too. I would definitely recommendDon patton2/02/2023Blow-in insulation. These guys were awesome---arrived on time (actually earlier than scheduled) and immediately started working. They worked non-stop throughout the entire appointment -- no side-chatter or lolly-gagging. They were focused, courteous, efficient. I had no doubts they knew exactly what they were doing, and if I had any questions, they immediately came to me, looked me in the eye and talked with me until my questions were answered. Highly recommend---I've already referred them to neighbors and friends; don't hesitate to choose them!Daniel Wooldridge1/15/2023
- Met with owner Tom P. about foam insulation in the attic of my new home. The builder had only blown in insulation in the rafters over the ceilings. After evaluating the attic of my home Tom recommended that I speak to my HVAC company about the two a.c. handles in the attic. Suggesting that if the handler’s weren’t engineered for an attic that had foam insulation I could have BIG problems with condensation, potentially leading to black mold. He also stated that the manor to which the builder insulated my home was normal and that 90 percent of the homes in Texas were insulated this way. Assuring me my house would function fine the way it was insulated. Tom never tried to sell me more then I needed, it’s a credit to his character and the way he does business. I would recommend Geo Insulation to others who are in need of expertise and or insulation. Thank you Geo Insulation.Gene West1/09/2023Absolutely love the insulation we had put in! I could feel the difference in our house the same day. The team was professional, quick, and informative on the whole process. Tom was super friendly and willing to answer all of my questions. He takes pride on keeping his business small and making sure all customers have their needs met. Thank you for the great service!Jonathan De La Cruz1/09/2023Used Geo-Insulation for blown in attic insulation to replace what insulation was lost with the load bearing wall removal, as well as top off attic space over the livable space. Tom and his team were great to work with. He was prompt in coming out and providing a quote, he was great when I had to keep pushing out the install day due to a couple unfinished tasks, and his team that came out did a good job of adding more insulation. The price was reasonable and the customer service was great.Trevor Holbrook12/04/2022Tom and his crew were on time, and worked quickly to complete our insulation work on a new construction project. They installed Bat and blown fiberglass. They left the jobsite cleaner than they found it! Thank you Tom and the great guys at Geo Insulation! Oh and I almost forgot the best part, they were the least expensive of the 4 bids we received. I highly recomend this company! Ronnie Manes Punch Construction Servicesronnie manes11/16/2022They did an attic insulation great job. They make thick the same in my house and product is good too. They cleaned after finishing. Tom and his team are very nice and friendly. I recommend you to Geo-Insulation, please contact with them if you need.Vincent Nguyen11/09/2022The owner explained the process to me personally and the crew arrived on time, did the work in a professional and timely manner and cleaned up before they left. Then the owner followed up with me after the job to make sure that I was satisfied with the installation. Very happy with the job that they did and the service that I received.Bill Mahone10/29/2022
- Tom and team did a great job installing batting and 10” of insulation. They showed up on time, worked quickly, and left the work site clean.Ann Janoe10/10/2022Tom is very knowledgeable about insulation of all types! Very friendly, communicates well. He also has a list of many contacts to help with what you need if he is not able to do it himself. Highly recommend!Alison Messer10/07/2022Tom and team were fantastic. They removed and installed new insulation quickly and expertly. I would recommend them to anyone who asked. He even helped with filing the energy rebate.Chris Alexander10/04/2022Daniel Cedar10/04/2022Great service. All my questions were answered and Tom helped me figure out the best plan and revisions on how best to add insulation to an old house.j t10/02/2022I recently purchased an older home a few months back and after living there for that time I noticed the temperature in the home was becoming an issue. The AC unit was constantly running and the home was not maintaining the temperature as it should. I decided to reach out to Geo Insulation for an attic insulation quote. My phone call was answered right away and Tom scheduled me for an inspection. He arrived on time and was very professional and courteous during his visit. He was able to answer all my questions and gave me additional information on the insulation process. I had a few other companies come out to inspect and it was just a waste of time. They were rude, non-informative and dismissive when I voiced my concerns. On the day of the instillation Tom and his team were punctual and prepared to begin the job right away. They were all very respectful of my home and were very careful not to bump into any of my furnishings as they setup their equipment. The whole experience with Geo-Insulation was very positive and Tom was attentive to all concerns and questions I had; he quickly took the time to address them. I am very happy with the outcome of their work and felt the difference in my homes temperature almost immediately! I recommend this company 100%.Isaac Isaac9/28/2022

Reasons to call Geo-Insulation
as your home insulation contractor
Properly insulating your home or building helps to maintain comfortable temperatures year-round. No matter what kind of insulation you currently have in your attic, you can quickly determine if you need more by looking across the span of your attic. If your insulation level is below your floor joists and less than 14 inches deep you should add more loose fill fiberglass insulation. It is important that the insulation be evenly distributed because sometimes there is enough insulation in the middle of the attic but very little along the eaves.
Insulation levels are specified by R-Value, which is a measure of the insulation’s ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 or about 13 to 14 inches.
CPS Energy presently offers a rebate program to help offset the cost of adding insulation to your attic floor or foam insulation on the attic roof decking. For additional information please contact Tom Porter, (210) 848-5658 or visit CPS Energy Rebate Program website.
