Our Reviews

Here are just some of the nice things that our customers have to say about us.

  • Unparalleled service! I worked with Geo-Insulation to blow insulation in my attic. Geo-Insulation was without a doubt the best value. I researched several companies and they were the most competitive bid along with value and customer service. They were very responsive, had quick turn around times, and accommodated my schedule. They are very easy to work with and made the CPS Energy rebate process so easy I didn't even have to think about it.

    Geo-Insulation replaced both attic insulations in my home and did an outstanding job! Their quote was nearly half the price of a well known statewide chain company, and even including disinfecting solution and sealing all attic spaces (which the other company did not offer). The owner was there himself throughout the process and even brought to my attention a small leak in my roof which needed repaired. My house smells fresh and clean now, and is so much safer for my family. I would definitely recommend Geo-Insulation if you have similar issues in SA. The owner has definitely earned his nickname as the "Critter Whisperer"!

    Tom is extremely knowledge and takes the extra steps to ensure the right solution for your home. I talked to 3 other companies who were all just trying to sell me their product (spray foam insulation). Tom made sure to have an outside this party inspect my home to ensure his product was the right thing for our home. His staff is courteous and professional! Highly recommend.

  • Tom, of Geo-Insulation, responded quickly and positively to my request for a small insulation project in my attic. I had contacted four other companies for the same project. Two never responded, one said they didn't do this type of work, and the last one said they did this work, but the job was too small and not worth their time. Tom, however, agreed to perform the work and was at my home the first thing the next morning. He was friendly, knowledgeable, professional, and reasonable. I would recommend him without hesitation.

    Tom earned every one of these stars, from the beginning of the bid to the final instal everything was top quality. I really appreciated that he listened to my needs and didn't try to upsell me on something more expensive. He also provided me references where I could learn about the instal process and feel more comfortable with it since I had informed him I had a family member who is immuno-compromised. Additionally the team was extremely careful with my home: household items and landscape. Total Professional!

    Geo-Insullation is a MUST for your home. We put them through hell with multiple requests to come out and never being ready (Not to mention COVID 19 and the uncertainties with the economy). The company was so understanding of our reservations and never hesitated to provide us with an estimate each time. Tom (the owner) personally responded each time with patience and thorough explanation. We finally pulled the trigger and cannot be happier. Professional. Clean. FAST! And a HUGE difference. We opted for radiant barriers plus 12 inches of loose fill fiberglass + removal of the old yucky stuff. My husband works from home and there was no disturbance whatsoever. Simply hands down great decision.

    Very pleased. We had an excellent experience with Geo-Insulation! This is a local-owned company and we dealt directly with the owner. Tom got in the attic to ensure what was needed. The price was way less than we expected and much less than other quotes, and he processed the CPS rebate for us. There is a noticeable difference of comfort in our home.

    Tom Porter and Geo-Insulation crew are heroes.On Monday, I requested quotes from 3 companies through HomeAdvisor to insulate my 625 sq ft attic. Tom Porter of Geo-Insulation responded by phone within hours. Based on my verbal description, he provided a written quote that evening. I called Tom back on Tuesday requesting a requote because I didn’t mention the job had a hip roof and I wanted baffles between all rafters. Tom phoned that evening and provided a new written quote by Wednesday morning. One of the other two companies contacted me Tuesday evening and reviewed the site Wednesday morning.The 2nd company provided a verbal quote at twice the price of Geo-Insulation, promising a written quote by Wednesday but never received.Wednesday evening, I contacted Geo-Insulation to do the job and Tom Porter promised to install Saturday morning of the same week. As promised they arrived on time, completed the job within 3 hours, cleaned up any debris and delivered everything requested and promised.Coming from a construction background, I highly recommend Geo-Insulation because of their follow-up response, professionalism, price and quality of work.

  • Where do I begin?Due to a Rodent under our home, needed to have all the wet Insulation under our home replaced. Contacted several Companies. Tom Porter, owner Geo-Insulation, gave us the best deal for Spray in open cell foam. Tom worked with us and did the job in two phases. Stripped old wet insulation out and came back when I used a fan to dry the floor underneath. Because of freezing weather forecast, called Tom and he rescheduled the Job, came out the next day and our home is now we insulated.To my wife and I, Tom is the best. Tom and his Guy's at Geo-Insulation are the best. Fair, dependable, quality work & product and very Personable.

    Tom provided outstanding service throughout the entire experience. He was prompt in every engagement, knowledgeable, conscientious, and overall he and his crew did an outstanding job. His guidance on the CPS rebate process was also very helpful. I would highly recommend Tom and Geo Insulation, and in fact he has earned business from a lot of the neighbors now as well. The cost was very reasonable as well for our insulation job.

    Tom is hands on the whole project, he is part of the crew and he is the owner. It’s great to have a home project scheduled and completed while only having one point of contact through the entire process! Tom had the CPS rebate paperwork filled out and ready day of the project. Another huge plus for me, he did everything he said he was going to do, meeting times, project time/date, complete follow through, this was so refreshing. Overall very clean, quick and courteous, with straight forward fair pricing! You won’t be sorry hiring Tom and Geo-Insulation.

  • For anyone needing insulation work done, we highly recommend Tom Porter and his crew with Geo Insulation. Tom is very knowledgeable about his trade. He and his crew showed up promptly, worked very hard, and did an exceptional job of insulation removal and loose fill fiberglass installation. They were well organized, respectful, and cleaned everything up. We couldn't be more satisfied.

Specialists in Attic Insulation
(Fiberglass/
Foam Insulation) & Radiant Barrier

in San Antonio

Geo-Insulation specializes in open/closed cell foam, fiberglass attic insulation, and radiant barrier spray in San Antonio. While most of our work is residential, we also offer our services to commercial clients.

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.
