Koala Insulation of Texas Hill Country

Koala Insulation of Texas Hill Country runs insulation work from San Marcos. Andrew leads the company and delivers services such as spray foam insulation, blown in attic insulation, insulation removal, batt insulation installation, air sealing, crawl space encapsulation, and commercial insulation for homes across the Texas Hill Country area.

Homeowners call for attic insulation replacements that start with removal of old material followed by cleaning and new blown in insulation. Crews including Sergio, Anthony, Arthur, Frank, Alex, Austin, Ezra, Antonio, and Ian complete these jobs along with spray foam upgrades after removal. Reviewers note cases where old insulation from decades prior gets replaced with thicker blown material that improves comfort, and some jobs finish the same week after an initial inspection.

Andrew and the team respond quickly to requests, show up on the scheduled day or even early, keep homeowners updated at each stage, and leave the property clean with no leftover debris. Pricing stays competitive without pressure to select higher cost options, and the work covers spots in San Antonio and surrounding Texas Hill Country locations. Crews finish most attic projects in a few hours while respecting the home during the process.

The crew was accommodating, reliable, gave advanced notice before their arrival and arrived on time, walked us through the process before starting, and worked efficiently with minimal disruption to our day.

“⭐⭐⭐⭐⭐ 5 STARS – Outstanding Service from Start to Finish! I want to give a huge shout-out to Koala Insulation of Texas Hill Country for an outstanding job on our home! We recently had our old attic insulation removed, the attic cleaned and treated, and brand-new insulation installed. From start to finish, the entire team was absolutely wonderful to work with. Everyone was extremely friendly, courteous, knowledgeable, and professional. You could tell they took pride in their work and cared about doing the job right. One thing that really impressed us was how well they cleaned up after themselves. They respected our home, kept things professional throughout the process, and made sure everything was cleaned up when the job was finished. The before-and-after pictures speak for themselves! What a difference! The attic looks fantastic, and it's a great feeling knowing this major home improvement has been taken care of. These days, finding a company that combines quality workmanship, professionalism, and genuine customer service means a lot. Koala Insulation delivered on all three! Thank you to the entire crew for your hard work and for treating our home with care. We truly appreci”

“Koala did a fantastic job on our Attic Insulation upgrade. From the prompt, detailed inspection, through the recommendations, estimate, and agreement, Andrew was extremely professional and detail oriented. Frank and Sergio showed up on the agreed date and time, and got to work. We hardly noticed they were here, but they were hard at work, and completed our job by lunchtime. Professional, pleasant, and patient, they answered a few questions, which confirmed that they were well informed of the specifics of our job. Job completed, our paperwork was promptly sent, and included all the details needed for a Rebate from our energy provider, CPS Energy in San Antonio. The Rebate was approved in less than 24 hours, and I am looking froward to smaller eneergy bills, and Rebate money to help pay for our bills. And possibly a tax break from the IRS on our 2026 taxes. We will confirm that with our tax preparer next year. Koala also provides all this info on their web site. It really helps reduce the direct cost for the insulation upgrade. Thank You, Koala - I wish all companies were this easy to deal with.”

“Only House meetings a lot of work and years and taken refuge in the attic and made a big mess. Koala was very thorough backing up in our replace it with blowing insulation as greatly increased of the house. Their work was exceptional, and I would highly recommend them.”

“I met Andrew from Koala at the San Antonio Home Show\. He was informative, easy to talk to, and took the time to answer my questions, so I had him come out to provide a quote for removing and replacing my insulation. Andrew showed up on a Saturday right when he said he would and walked me through several options without any pressure or sales pitch. We chose the option that worked best for us, and at no point did he try to upsell us or push us toward the most expensive option. His crew was on time, actually early, and had the old insulation removed before lunch. Since I also needed ductwork done, Andrew recommended waiting to install the new insulation until that work was finished, which kept the new insulation from being disturbed. His crew returned the next day and completed the job. Everyone was professional, punctual, and easy to work with. Was Koala the cheapest? Honestly, I don’t know. After talking with Andrew, I felt comfortable with the company and didn’t feel the need to shop around. I highly recommend Koala and would absolutely use them again or recommend them to friends and family.”

“Andrew Horvath came to my house for one of their free insulation consultations.

“Koala Insulation dba Java Corp did an excellent job bringing our attic insulation up to date. They were on time, completed their work on time and left our home clean. This contractor I would highly recommend! Very thorough pre-inspection of our attic and what was needed to be taken care of. Then Andrew sat down with us and explain exactly what was needed and why, then followed up with a detailed written bid. We got three bids and they were right in the middle and very competitive. We are extremely happy with the work that they did and we are glad that we chose them.”

“Wonderful work, the owner personally gave me a quote and fit me into their schedule when a previous company that I hired failed to show up to the job. The techs were extremely professional and respectful of my home and cleaned up after the work was finished. The insulation was packed correctly and I couldn't be happier with the service provided. Thanks koala! 🐨❤️”

“Koala Insulation was the #1 choice out of five companies I researched. The owner (Andrew) was professional, fair and reasonable pricing and supports military with a discount. He was awesome, friendly and explained everything in detail. The three man team came out the next day after I confirmed the work. The team was professional, friendly, answered all my questions and cleaned up after they finished insulating two walls. I recommend this company they are a 5 out of 5!! I am going to use Koala Insulation again for my future projects.”

“65 years old home with probably 65 years old blown insulation. Koala insulation was quick to respond and provide data and visual information that showed all the hot spots that were plaguing our house. They were able to draw up a solution based upon the extreme temperatures and architecture of the house in order to substantially reduce the trapped heat before the Texas summer heat really kicks in. Pricing was fair and we were not pushed or pressured to buy beyond our budget. Excellent communications and superb client service to enhance their customer experience.”

“"Professionals," from start to finish. It was a matter of minutes after sitting down with Andrew that we knew that we would be doing work with his company. The labor was approachable, punctual, detailed, and thorough. There were no new price increases, or needed work after our first consultation. The quality of work was more than what we hoped for. I highly recommend this company.”

“The guys arrived on time and did a fantastic job of inspecting the attic and blowing new insulation! Efficient, tidy, respectful of property, and professional. Kudos to Ian and Sergio! I highly recommend their services.”

“I haven't had a need for Koala's services in the past, but on one Real Estate transaction, it was absolutely imperative to have Koala on the job! They were quick, responsive, and accommodating to the needs of the job in front of me. Great work, great communication, and great outcome. Thanks Andrew.”
