Trusted
Your Blown-In Insulation Team in Jacksonville
Jacksonville’s hot, sticky summers and occasional winter chill can make your home feel uncomfortable and your HVAC system work overtime. The surprising part? A large share of homes here still rely on a thin, decades-old layer of attic insulation that falls well below current recommendations.
Best uses for blown-in insulation:
Attic floors that need a fast, affordable R-value boost.
Knee walls & sloped ceilings and other awkward, hard-to-reach spots.
Wall cavities, in select retrofits, following industry best practices.
A Superior
Your Thermal Comfort Upgrade
Think of blown-in insulation as a thermal blanket for your Jacksonville home. Loose-fill material flows over the attic floor or into cavities and settles into complete, even coverage, layering neatly over existing insulation while standing up to sticky summers and occasional winter chill.
These capabilities define the insulation type:
Reduces Air Infiltration: With Koala’s air sealing working alongside it, the insulation layer helps shut down the framing and wiring gaps that let outside air slip into homes in Jacksonville.
Limits Condensation: Better attic R-value plus preserved ventilation means fewer cold surfaces where moisture can condense, protecting both your Jacksonville home and the insulation itself.
Advantages Of
Blown-In Insulation for Homes in Jacksonville
Blown-in insulation earns its popularity in Jacksonville: rapid installation, easy layering over existing insulation, reduced heating and cooling costs, and more consistent comfort across the seasons. The advantages do not stop there:
Improved Air Quality
When combined with attic air sealing, blown-in insulation helps cut down the amount of dust and outdoor pollutants that can sneak in through gaps around light fixtures, plumbing penetrations, and attic access points in homes in Jacksonville.
Water & Fire Resistance
The blown-in products we install are designed with fire safety in mind. Proper installation around recessed lights, chimneys, and other heat sources is critical, and our team follows local codes and manufacturer guidelines to help keep your Jacksonville home safe.
Pest and Wildlife Protection
Pest deterrence is a real, if lesser-known, benefit: cellulose blown-in insulation (uniquely among loose-fill options) is treated with compounds that discourage insect nesting, and air sealing the attic closes off the gaps pests use to get into homes in Jacksonville.
Soundproofing
Noise reduction is a welcome bonus for Jacksonville homeowners: the dense loose-fill layer soaks up outside sounds and dampens noise moving between levels, from street traffic to kids playing overhead.
Environmentally Friendly
Our blown-in insulation is made from recycled materials, making it an eco-friendly option. Insulation plays a vital role in reducing carbon footprint by making buildings in Jacksonville more energy-efficient. Studies have shown that insulation can reduce heating and cooling energy consumption by up to 40%!
Jacksonville’s Stress-Free 4-Step
Blown-In Installation Process
Free Home Efficiency Assessment
Our efficiency experts start with a thorough, no-cost examination of how your Jacksonville home is performing today.
- Prep for Safe InstallationPreparation sets up everything that follows. We shield floors and walkways, establish safe access, and distribute depth markers across the attic to verify the target level later. If the eaves of your Jacksonville home need them, baffles go in to keep insulation clear of the soffit vents.
Koala Difference: We carefully protect your home and prepare the area so your new insulation performs as it should, and your Jacksonville home is not left covered in dust when we are done.
- Air Seal Before We BlowWith prep done, sealing begins. Our team uses thermography to spot the leakage paths (plumbing penetrations, wiring runs, can lights, attic openings) and seals them before a single bag of insulation is blown into your Jacksonville home.
Koala Difference: We do not just “add fluff.” By combining blown-in insulation with strategic air sealing, we help you get more comfort and value out of every inch we install in Jacksonville.
- Install to the Target DepthInstallation day moves fast: material flows through the hose while our installers distribute it to the planned depth, fill awkward corners, and confirm against depth markers until every section of the attic in your Jacksonville home hits the target level.
Koala Difference: Thin spots quietly steal performance, so we measure and verify until coverage across your Jacksonville home is truly uniform.
- Wrap Up & Review
The last step is leaving your Jacksonville home spotless: we vacuum, clear our equipment, and seal the attic access correctly. Before we go, we review everything completed, show before-and-after photos where available, and cover how to keep your insulation performing.
Koala Difference: Consider us a long-term resource: future questions, maintenance advice, and guidance on rebates or tax credits that may apply to your project in Jacksonville.

My HVAC person recommended getting insulation in my attic since the AC wasn't keeping up with the Florida heat.
Koala came out and did an estimate, they kept me informed on when they were going to arrive, and everything went perfectly smoothly.
Within a very short period of time like hours I got the quote or estimate.
I'd been worried about the price, but it wasn't nearly as much as I was afraid it would be - so affordable - and I'm very happy about that.
Service day was set, again the crew doing the installation kept me informed on their ETA and they arrived when they said they would, I was not home at the time but when I got back there was really no evidence they'd done anything because they cleaned up after themselves and everything was put back an order, and we are all very very pleased.
I've already been preaching the benefits of attic insulation, and I've talked to some of my coworkers about it.
I don't know if they're always this quick, but my turnaround time was within a week I think it was very speedy and now it still is a terrible problem with the heat in florida, but more often than not the air conditioning can keep up with it which is going to reduce my utility bill.
Like the old saying, I wish I'd done it sooner but "when you know better you do better" :-)

Job was booked in under 2 weeks of estimate. And the gentlemen who did our insulation project were very kind, professional and didnt take too long. They cleaned up any mess and best of all our house is now staying much cooler inside. Thank you for the great work! Would recommend to friends and family!

Stephen, the salesman completely investigated all areas of the house needing insulation and identified some things other companies had not caught. The installation staff was courteous, efficient, and cleaned up after themselves. I’m very happy with the work provided by Koala insulation. I would recommend them to my friends.

Koala was very responsive to a “request” I made by calling their number. I wanted a review of my current attic system; air circulation, baffles, soffits, insulation factor, etc. About 2 weeks later they were out, and went into my attic and gave me the info I wanted in a very professional way so I could understand the exact status of my attic. From that I was able to ascertain what would be helpful for me to have done, and what (which I had imagined I should do, like have them seal all openings like bathroom vents, etc) would be overkill and not add significant value. I hired Koala, and a few weeks later they came out; big truck and two service technicians, performed the work, they blew in insulation increasing my attic R factor to 38, kept soffit air flow up to my attic ceiling solar-powered attic fans clear, stapled in plastic baffle guards where needed, put a cardboard wall up to isolate a rear centered area of my attic to ensure all blown in insulation covers the spaghetti area of my attic full of plumbing, electrical lines, etc. It was tight and very smooth. I am very happy with the outcome and “already” have noticed (b/c I put a temp/humidity gauge up there) the attic is cooler; the house temperatures are excellent, and the utility bills are already showing savings. I highly recommend Koala.

Wow! Looks like Mr Snuffleupagus exploded in my attic! The guys at koala really did a nice job from me. Collin, Jake, and John went over the entire job with me twice Venice leaving to ensure every spot was throughly covered and then some. I’m very pleased with the results. Summer isn’t here yet but both mt wife and I can tell a difference in the house. Just wish I would have done this sooner.

Koala Insulation is fantastic!! The whole process from start to finish was super simple. I wanted to get some updated insulation before the major summer heat sets in. I found Koala while looking for Blown-In insulation services. Stephen was the initial person who came to do the estimate, and he was great at explaining the process and listening to my concerns. Izzy and Jack came later THAT WEEK and did a great job! Very kind and they did a great job! Koala has the best estimate of the other two companies I looked at - very affordable, but not skimpy on quality. 10000/10 would recommend.

We recently used koala for blow in insulation for three separate loft spaces and at their recommendation two solar fans.
The quote and pricing process was efficient and prompt.
The team that installed the insulation were easy to work with and done a good job cleaning up at the end.
I was impressed when they ran out of materials at their first visit and came back with more.
Hard to tell if it’s made a major impact so far, but with so little insulation before it can only be better.
We would recommend, but it’s not inexpensive.

I needed my attic re-insulated so I contacted Koala. Bruce came and looked in my attic. He let me know what the company could do for me and once I approved his very reasonable price they came out within a few days and took care of everything. I'm very happy with their service and their work. I highly recommend.

Crew came and did a very good job, very professional
Highly recommend, even from the price point of view! I reached out to other vendors and definitely Koala came in as the best price and options

I had the pleasure of recently working with Koala. Everyone I met with the company was courteous and professional. The first person I met with the company was Bruce who gave me different insulation options to consider. He patiently answered all my questions the day I met him at my house and thereafter. Bruce was very fair in his pricing and was always responsive in getting back to me. I feel strongly that Bruce is an owner that stands by his service and believes in customer satisfaction. Kelly led the crew responsible for the blow in insulation of the first floor attic and removal of old insulation from the upstairs attic. Ryan led the crew responsible for the spray foam in the upper attic and the removal of insulation from the crawl space. The work done by everyone (those named as well as their coworkers) turned out great. I want to give Ryan a special thank you for coming out a second day to rake out and dispose of smaller insulation pieces on the ground in the crawl space and for answering my many questions He is very knowledgeable and courteous. I highly recommend Koala!

I had the pleasure of having Bruce come do my estimate, he was super professional, on time, flexible to meeting my needs for scheduling. He discussed the entire process thoroughly, even discussed why he wasn't going to upsell me and how it would be a waste. Showing honesty and integrity is a lost professionalism these days and was refreshing to see that in a business these days!! They gave me the best price for my job out of 3 companies. Scheduled me quickly to beat the end of year and allow me to take advantage of the tax credit. Ryan showed up on time, was super professional, polite, respectful of my home. Discussed the entire process from start to finish! Was quick, did great work, and was done on time. Michael the supervisor helped, he was also super professional , respectful of my home and belongings. Thoroughly discussed and explained it all. I am lucky and proud I chose Koala! Thank you guys for a phenomenal price and incredibly quality job!

I had an outstanding experience with Koala Insulation of Jacksonville from start to finish. Their pricing was fair, communication was excellent, and everyone I interacted with was incredibly professional, especially Bruce, the owner.
Two days before my scheduled install, my AC system started acting up and I ended up having to replace all of my ductwork. Bruce didn’t hesitate for a second, he worked with me, rescheduled everything without any issues, and made a stressful situation a whole lot easier. Truly above-and-beyond customer service.
When install day arrived, Isrreal (Izzy) and Jak were exceptional. They were professional, respectful, and handled the entire job with care and efficiency. What really stood out was their attention to detail, especially during cleanup. They didn’t just sweep up a few pieces of insulation, they swept my entire garage, leaving it cleaner than when they arrived. Extremely appreciated!
Koala Insulation exceeded every expectation I had. Thanks to Bruce’s flexibility and the outstanding work from Izzy and Jak, this was a true 5-star experience. Highly recommend them to anyone needing insulation work done!

We were having a problem with the plumbing pipes in the attic becoming very hot in the summer. So I called Koala Insulation, after hearing about them from an interview with Carren Reale, on WSOS. Bruce Hammer, with Koala Insulation came out to assess the problem. He combed the attic and determined that we could use some additional insulation, which would help our problem. He also found some areas in the attic where we didn't have any insulation! His estimate was very reasonable so we scheduled the service. His servicemen were prompt and did a wonderful job of adding the blown-in insulation. They were respectful and helpful. They addressed the special areas too. They cleaned up after themselves and even left an old tool which they had found. I would wholeheartedly recommend Koala Insulation to anyone needing insulation!

I think most people like us don't give insulation too much thought. We have lived in our home 25 years and it is 27 years old. Whoever thinks about compressed insulation? But we were doing a whole home remodel down to the studs and our contractor mentioned it to us. So, we contacted Koala. Highly recommended from our other contractor DM Design and Planning. Jack & Izzy did a beautiful job. My husband went in the attic and took pictures afterward. We thank you very much.

We recently had Koala Insulation come out to add insulation to our attic, and the entire experience was fantastic from start to finish. The whole team but specifically Connor and Ryan as they were the techs, were professional, punctual, and very knowledgeable. They took the time to explain the process, answered all our questions, and made sure everything was done right.
The installation went smoothly, and they left our space clean and tidy when they were done. We’ve already noticed a difference in the comfort of our home, and we’re confident this will also help with energy efficiency moving forward.
Everyone we dealt with was courteous and easy to work with—truly a pleasure. If you’re considering adding insulation to your home, we highly recommend Koala Insulation!

Koala Insulation did a fantastic job installing blown-in insulation in my attic. The team was punctual, professional, and explained everything clearly. Vaughan went above and beyond to fix an issue with an AC diffuser boot before covering it up with insulation. The work was done efficiently and they left my house mostly clean. I’ve already noticed better temperature control and lower energy bills. Highly recommend Koala Insulation!

I recently had the pleasure of working with Koala Insulation to add 4-6 inches of blown-in insulation to my two-story home. From start to finish, the experience was smooth and professional. The team arrived right on time and immediately got to work. They were diligent and hardworking, completing the job efficiently while ensuring minimal disruption to my household.

Kyle did a great job of giving me all the information I needed to make an informed decision.
The workers were friendly and knowledgeable. They completed a job in an attic with very little space and made sure every corner was covered.
After the job was complete, I had reservations about some of the work that was done. I received a personal call from the owner letting me know that he was handling the situation and that he would help us out free of charge. He just wanted us to be happy with the work completed.
This kind of customer service is a very rare find in today's market. This is an honest company run by honest people. They have earned my business going forward. I cannot recommend them highly enough.

Highly recommend Koala Insulation of Jacksonville. We were dealing with a heat/humidity problem in the attic. We had almost zero insulation in the attic. Kyle was very thorough and straightforward during the evaluation. The plan was good, made sense and was reasonably priced compared to other companies. No upselling, just a solution that works for my situation. Installation of blown insulation was right on time, done in 2 hours and zero mess. I am sure this will make a difference in HVAC and home efficiency. They'll be back to install attic fans at a later date. Would definitely recommend Koala Jax and work with them again!

How Much Does Blown-In Insulation Cost in Jacksonville?
Rather than quote a flat rate, we price every blown-in insulation project around a few specifics.
Three things drive the number: how large the home and attic are, which insulation material is used, and how much work the installation itself involves, including access, prep, air sealing, and whether old insulation needs to come out first.
Whatever the scope, the upgrade works in your favor over time: better attic coverage means less heat loss and lower heating and cooling bills.
Rebates from state and local governments and from many utilities can also help take a bite out of the total, and our team can point you toward what may be available. For a firm number on your Jacksonville home, skip the guesswork: contact us for a free assessment and a quote built on your actual attic.
Is Blown-in Insulation Better Than Rolls?
Blown-in insulation is usually a better attic solution than rolls (batts) because it creates a more consistent, continuous layer across the attic floor. It fills around joists, wiring, pipes, and odd corners where rolls often leave small gaps. Those gaps may not look like much, but they add up to drafts, uneven temperatures, and lower real-world performance in homes in Jacksonville.
How Much Blown-In Insulation Does My Attic Need?
The right amount comes down to three inputs: the square footage of the space, the insulation depth required, and where you live (see the map below). Climate drives the recommended attic R-value, with colder regions needing thicker insulation to slow heat loss and warmer regions needing enough depth to block heat gain. Attic size and target R-value together set how much material consistent coverage requires. For reference, Jacksonville falls in IECC Climate Zone 2A (hot-humid), and DOE and ENERGY STAR guidance for that zone puts attic insulation at roughly R-30 to R-60.
Because insulation requirements vary by region, professional installers base material calculations on climate-zone guidelines, existing insulation levels, and manufacturer coverage charts rather than estimates. This ensures the insulation depth matches the recommended R-value for your area, accounts for natural settling, and avoids gaps that reduce performance. The diagram below shows how recommended attic insulation levels change by geographic region, helping homeowners understand why insulation needs differ from one location to another.
