"Why you should upgrade your home’s insulation"

According to the Department of Energy, "Space heating and cooling account for almost half of a home's energy use, making this one of the largest energy expenses in any home.”

As your home ages, your insulation begins to deteriorate - as do the seals around your windows, doors, and lights. Did you know that 50-70% of the energy used in your home consists of heating and cooling? By reinsulating your home, you can save money each month on your utility bill.

A properly insulated home is more comfortable, and the air will stay cleaner. Insulation and air sealing ensures that conditioned air stays inside your home. With poor insulation, your HVAC system works very hard to continuously condition air which seeps in. This air which seeps in is often very dirty and totally avoidable.

The best way to reduce your home's carbon footprint is by reducing energy waste through increased efficiency. According the the EPA, the #1 way to reduce your energy usage in your home is to improve the building enery efficiency through better insulation. Retrofitting can allow new and existing homes to upgrade their insulation.

Have you been in your home and wake up to birds chirping or your neighbor's dog barking outside? Maybe the weather seems louder than it should be. Insulation combats outside noises and also helps with reducing the amount of noise carried from one room to the other.

Better than excepted. Great job and they cleaned everything up. Plus, the new spray foam insulation is working great. Much Cooler and much quieter. The cost was reasonable. Great value for what they did.

Hassle-free batt insulation replacement! Koala was well-priced, quick and tidy with replacing my attic insulation. I will use them again for soundproofing my basement.

James and his team did an excellent job at our place. His customer service was top-notch. We had our attic insulated, and it turns out to be a complex and complicated job, but James and his team didn’t hesitate in giving us support and working hard to have it perfectly done.

The team at Koala is professional and personable. They told me exactly what I needed and didn't pressure any add ons or extras. The turn around time was much quicker than expected. My house is definitely cooler than it's ever been in previous summers and we saved money on our electricity bill in the first month. I highly recommend them.


Charles Wilson

The Koala team was extremely knowledgeable and patiently answered all of my questions. They were very professional and honest. Insulation was added in my attic to the proper level, and a solar fan was also installed. I am saving more than $1.25 PER DAY which is amazing. I would absolutely work with the Koala team again, and strongly encourage others to do so!


Annette Wilson

After last winter's cold, my husband and I decided that we were going to explore ways to keep the house warmer. We asked Koala Insulation to give us an evaluation of our attic insulation. They were on time, professional and thorough in doing so. They recommended more insulation, a solar attic fan and putting insulation on the attic door. The price we were quoted was, in our opinion, very fair. We then had other companies do the same thing. In comparison, not only did Koala seem to assess our needs more thoroughly but were the most reasonably priced. When they came to do the actual work, they were polite, clean and professional. They did excellent work, were as quiet as they could be and worked quickly but comprehensively. They told us that we would start seeing savings on our bill and they were not wrong! It just made me wish we had done it sooner. I heartily recommend them without reservation.


John Leedy

Christian Mueller and his team did an excellent job of adding blown insulation in our garage attic. I was impressed by their professionalism, explaining the job and cost to us, communication as to when they would arrive and punctuality. Top notch company.


Christopher Otero

Koala Insulation completed two services while at my home - adding insulation to the attic and installing a solar fan to increase air circulation in the attic. They arrived at 8am and were done by noon with everything. Brandon, Christian, and the third technician (I'm so sorry, I don't remember his name) were all incredibly nice, informative, and respectful of being inside our home. Brandon even came back out a few days later to address a few questions that I had, which I feel is above and beyond. The pricing was very fair, as well. If you need insulation work done and/or a solar fan added to your attic, do not hesitate to call Koala Insulation of North San Antonio.


Jeffrie McDonald

Brandon and team did a great job adding attic insulation, fast and no mess. House sounds quieter and Electric bill is lower year over year by 18% already after 2 months…I expect bigger savings in winter months, highly recommend this investment in your home.

First of all, I rarely do recommendations, testimonials, or surveys. I figure if I pay for a job or product why should I give out free advertising!! So why now? I was really impressed with every aspect of the Koala process. Great attention to detail, on-time installation, extremely knowledge about the installation of insulation products and related trades. They even found that my dryer vent was not properly installed and they repaired it without any additional charge. Clothes dryer lint was blowing into my attic for 8 years. I really chose Koala because they were the only insulation company that I got quotes from that would apply foam pipe insulation on the water pipes in my attic. Having grown up in North Texas all the water pipes were under the house or in the slab. When I moved to San Antonio my builder told me that it was NOT a problem to have water pipes in the attic under insulation. WRONG!! I even paid extra to have all the pipes insulated with foam pipe insulation when my home was built. Seems the builder only put the foam on the copper pipes that were visible in the attic. Last February I had one pipe that froze and ruptured and created a nightmare. Koala added over 250' of foam pipe insulation....REALLY...So are you asking yourself what does my attic have?? I also thought I had R 30 in my attic....WRONG.....some areas not easily visible from the attic entrance there were 2 inches of insulation or maybe R 5. My 18' high by 20' long entryway had R11. I had Koala install R 49 with blown-in fiberglass. I also found out the hard way that not all fiberglass insulation is the same. I don't want to go through another winter blast in the future ill-prepared. Koala uses Knauf Jet Stream Ultra Fiberglass insulation one of the top brands and it is not that much more than the cheap stuff!! They can also quote you the cheap stuff if you want but it will take more to equal the R factor of Knauf products and cost about the same. My grandmother always said you get what you pay for...so true! I guess I could have just said "I highly recommend Koala" but then you might have ignored the recommendation. Don't chance going through another winter with improperly insulated water pipes in your attic and low R-value insulation. Call Chris at Koala!

I contacted 4 companies to get estimate to get Corning insulation blown into attic. Two called back almost 14 days or more later. The third one I scheduled to do the work but no-showed (South Texas Insulation). Last one Koala, was contacted after the no-show. Koala responded to request within 2hrs and scheduled my work with no hassles and easily accommodated my flight schedule since I mostly live in the Rockies. On day of work I received a ETA. They were kind, organized and efficient. When completed, the area was cleaned and then they reviewed work done with me. I paid less money and got a lot more in service and professionalism. I hope Koala does well as it is well deserved. By the way, they take Apple Pay.


Cheryl Perez

I am soooo pleased I decided to use this company. There was no high pressure tactics. Everything explained to me to where I could understand. All my questions answered, they worked with my budget and when I decided to add additional insulation they found a way to meet my needs. Don't hesitate to call them.


Alice Pierpont

Prompt, thorough and courteous. We were given options at a reasonable cost and they cleaned up after the job was finished. Highly recommend.


Nicole Stephens

We contacted Koala because of a specific energy efficiency we were trying to achieve, and we had unique roof/ attic spaces. Their quote was affordable, and the work was completed quickly and the team was efficient and tidy. Great communication all the way through, and great pricing!


Hogen Oliver

I recently had Koala Insulation of North San Antonio increase the attic insulation in my house. The service was fantastic. Christian, Matt and Mike arrived at the scheduled time and were very polite. They explained the entire process and provided before and after pictures. I am extremely happy with their service and highly recommend them for your insulation needs. Definitely 5 star!!


Josseline Keity

Excellent service! The owner, Christian was knowledgeable and provided us with lots of education around insulating our attic. Pricing was fair as well. Would highly recommend


Corey Portman

The team at Koala Insulation did an incredible job insulating my attic! The old insulation had deteriorated and was not providing any sort of insulation whatsoever. Christian came out to my home to inspect the work, provided me several options to choose from, and had me added to the schedule to have the work performed within a couple of days. The team that came out to install the insulation was fast, friendly, and did a complete and thorough job. I've immediately noticed a difference in the temperature. To top it all off, Christian even provided me all of the necessary paperwork and instructions on how to apply for a rebate from CPS Energy. I would highly recommend Koala Insulation!


Dee Rogers

everyone did a great job. they were on time and cleaned up after themselves


Eric Summers

Koala Insulation installed a solar fan in my roof/attic, installed several soffit baffles after clearing them out to allow for proper ventilation and supplemented my existing insulation for my home plus added insulation above my garage.

I'm so happy with Christian (owner) and Matt (Operations Manager) and their team of friendly, hardworking guys. I would absolutely recommend these guys to anyone as they're honest and do fantastic work.


Joshua Deal

Just bought a house last month with my girl friend and needed new insulation. Reached out to a few places on quotes. Not only was Koloa insulation 1 of the best on cost but also was fast to reply! Got a quote and within the same week they were able to come on and get it knocked out in 3 hours!

During the quote process they took their time. Took pictures of how the insulation in the house looked and a break down on what it all will entail! They knew their stuff and the house is much cooler and staying cool right before the summer!


Robert Korbar

They did a custom spray insulation job on my van. They were polite and on time.


Dwayne Rolniak

Additional Insulation for our home. After looking for someone to install insulation over my garage they came out to my house quickly and on time. I was given an honest appraisal of what I should get and what I probably do not need additionally as far as insulation. I was given several options and once we decided which option we made an appointment the same week. Again they showed up on time explained what they were going to do and completed the job quickly and cleanly. I would highly recommend these guys for insulation for your home.


Jeremiah Cope

Hired Koala to install insulation on a property. They're communication with me and my tenant were incredible. Pricing was very fair and the explanation of options and benefits were fantastic and helped with my decision. Will us again when I need insulation


Dee Zimmerman

Bottom Line Up Front: Koala Insulation did a great job and we would recommend them.
The Details: Shortly after we bought our 1961 home, we discovered the previous owners left their herd of tree rats in the attic but didn't tell us about them. The rats had been in there for years as evidenced by the destruction and rat super-highways along ceiling joists and across a/c ducts. After we evicted the rats, the old attic insulation was full of rodent urine and droppings and it smelled terrible. Koala came out and gave us a fair estimate, removed the old insulation, and blew in new fiberglass insulation. They did a great job. This was no easy task. The attic space is very low in some areas and made the job tough. To make things worse, this old attic is criss-crossed with a plethora of telephone wires, electrical wires, alarm system wires, cable tv, etc. that has been added over decades. Everyone we deal with was polite, and knew what they were doing. Get this! They gave us a date and time, worked with our schedule, and even showed up on time! This may be one of the first times that a contractor showed up in San Antonio at the given time! This was a multi day job and they were always there when they said they would be AND THEY CLEANED UP after themselves. Another first. Other contractors in San Antonio could learn something from this business model.


Bruce Krueger

They did a marvelous job of installing blown in insulation in all areas of our attic. They were very professional and did a great job of protecting our surfaces and cleaning up when they were done.


Andrea Gonzales

Contacted Christian to come out to see what our attic needed because the house was getting cold quick. Came out quick and on time and their team found multiple spots that were severely low.I was able to schedule the job the same week and they came out and did a great job. Even vacuumed the carpet afterwards 10/10 would recommend. Thank you!
