Local Blown-In Insulation Experts in South Atlanta
South Atlanta’s long, humid cooling season and cool winters can make your home feel uncomfortable and drive your energy bills higher. Many homes in South Atlanta still have only a few inches of insulation in the attic, far below current recommendations.
Blown-in insulation is ideal for:
Attic floors to quickly boost your R-value to modern standards.
Wall cavities in certain retrofit projects, following industry best practices.
Knee walls & sloped ceilings for those hard-to-reach areas.
A Superior
Whole-Home Thermal Upgrade
South Atlanta homeowners and businesses choose blown-in insulation because it upgrades comfort and efficiency in a single visit. Installed as a continuous layer over the attic floor or packed into cavities, loose-fill performs like conventional insulation while going in faster and covering more evenly, even over existing material.
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 South Atlanta.
Helps Control Moisture: By raising attic R-value while keeping soffit airflow open, blown-in insulation helps curb the condensation cycles that sap efficiency in South Atlanta.
Advantages Of
Blown-In Attic Insulation in South Atlanta
Why do so many South Atlanta homeowners pick blown-in? It installs in hours, not days, goes right over what is already in the attic, and supports lower energy bills and steadier year-round comfort. Here is what you gain:
Improved Air Quality
An insulated, air-sealed attic is a cleaner attic. Closing the pathways around fixtures, wiring, and the attic hatch helps keep dusty, unconditioned air out of your South Atlanta home.
Water & Fire Resistance
Safety first, always. The loose-fill products we install are designed for fire performance, and our crews follow manufacturer guidelines and local code requirements around recessed lighting, chimney chases, and other heat-producing fixtures on every project in South Atlanta.
Pest and Wildlife Protection
Cellulose blown-in insulation, and only cellulose, carries additives that help discourage insects and pests from settling into your attic. Add proper air sealing to close entry gaps, and attics in South Atlanta stay cleaner and more comfortable.
Soundproofing
Insulation quiets as it insulates. A deep blown-in blanket absorbs sound traveling in from outside and between floors, so traffic, neighbors, and upstairs footsteps all fade into the background of your South Atlanta home.
Environmentally Friendly
Efficiency and sustainability go hand in hand here. Blown-in insulation is produced from recycled materials, and because studies show insulation can reduce heating and cooling energy use by as much as 40%, every winter and summer in South Atlanta costs the planet (and you) a little less.
South Atlanta’s Stress-Free 4-Step
Blown-In Installation Process
Free Home Efficiency Assessment
It all starts with a free visit: our team evaluates your current insulation levels and overall efficiency so recommendations fit your South Atlanta home, not a template.
- Protect & Prep the SpaceGood installs begin before the blower starts. Our crew protects your floors and walkways, sets up safe attic access, and places depth markers throughout the space so the finished level can be verified corner to corner. Where homes in South Atlanta need them, we add baffles at the eaves so soffit ventilation stays open.
Koala Difference: The payoff: insulation that performs as designed, and your South Atlanta home left exactly as clean as we found it.
- Air Seal Before We BlowThis is the step most installers skip: guided by thermography leak detection, we seal plumbing, wiring, and recessed-light penetrations plus the attic access in South Atlanta, so the insulation above works with a tight ceiling below.
Koala Difference: Anyone can add material. Sealing first is how South Atlanta homeowners get full value from every inch of new insulation.
- Blow In & Level the InsulationThen comes the main event: loose-fill is blown across the attic to the target depth and R-value. Corners, eaves, and the hard-to-reach pockets typical of homes in South Atlanta get deliberate attention, and we keep verifying against the depth markers until the whole space reads level.
Koala Difference: Thin spots quietly steal performance, so we measure and verify until coverage across your South Atlanta home is truly uniform.
- Wrap Up & Review
The last step is leaving your South Atlanta 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: The relationship outlasts the project. Koala Insulation of South Atlanta stays available for questions and can point you toward rebates or tax credits you may qualify for.

Austin and his crew were very professional and I am very pleased with the work they did today. They were very careful inside my home. I’m very appreciative of that since getting to the area to be foamed was not easy. I would definitely recommend Koala Insulation without hesitation.

They did a great job spray foaming our rafters and walls in our add on. It made a huge noticeable difference immediately and we do not even have our heat and air turned on yet. Highly recommend! Pricing is very fair also

Took the time and made sure the vacuuming of our prior blown-in in the attic was cleaned out and then did a great job of coating our attic roof with Open cell, About 4 to 5 inches deep all around.Fast and a good communicator.

I don’t know how to give a higher recommendation. i’m sure you all have experienced being a number online and waiting for days for people to call, no problem here, incredibly professional work and customer service and they actually talk to you. My wife and I could not be more happy with the foam insulation job Austin and Chad did for us thank you again guys 😊👍Dr and Mrs T Barry Clower

The air conditioning in my office upstairs was running constantly, and still it was uncomfortably warm. So I did my research on spray foam insultation and nearby companies. I contracted with Koala Insulation of South Atlanta, and I couldn't be more happy with the results. It was 140 degrees in my attic when they started and after they finished, it felt like a warm summer day in the attic. I could tell the difference almost immediately, and now, it's a comfortable 78 in my office. I look forward to a significantly lower power bill. Austin and his team did a fantastic job and I highly recommend them.

I recently hired koala insulation to upgrade the insulation in our attic, and I couldn’t be more pleased with the entire experience. From the initial consultation to the final cleanup, the team was professional, punctual, and incredibly knowledgeable.
They took the time to assess our needs, explained the options clearly, and provided a fair, detailed estimate. On installation day, the crew arrived on time, worked efficiently, and treated our home with care and respect. Within just a few hours, our attic was fully insulated, and the difference was immediate—our home feels much more comfortable and our energy bills have already started to drop!
What really stood out was their attention to detail and commitment to quality. They didn’t just do the job—they went above and beyond to make sure everything was perfect.
Highly recommend Koala to anyone looking for reliable, high-quality attic insulation services. It’s one of the best home improvement investments we’ve made!

Austin is the best! After several quotes, Austin was honest, straightforward and easy to trust with removing the old insulation, getting the new insulation up to code without breaking the bank. The work was very efficient and they cleaned up afterwards. Highly recommend this company!

Highly recommend these guys. You call, they visit, tell you what you want to know and then get it done all in a very timely fashion. If your upstairs is hot call these guys first and get your insulation checked out - I did and now my upstairs is cooler than my downstairs…thanks Koala!! Plus you may qualify for a rebate from your power company. I didn’t even know that until the guys at Koala shared that with me. Two thumbs up!

I recently had Koala Insulation install fiberglass insulation in my home, and I couldn’t be more pleased with the experience. From start to finish, their team was professional, knowledgeable, and efficient. They took the time to explain the process, answered all my questions, and ensured that everything was done to the highest standard.
The installation itself was seamless, and I immediately noticed an improvement in my home’s temperature regulation. Their attention to detail and commitment to quality workmanship truly stood out. Plus, they left the work area clean and tidy, which I really appreciated.

Austin was very prompt at responding to texts and was able to give an estimate and schedule quicker than anyone else while also beating their quotes.
Blew in more fiberglass insulation than needed to and followed special requests to cover duct work and make sure soffits weren’t blocked.
My house is actually staying at the temperature it needs to rather than the a/c struggling all day.
Much appreciated Austin. Thank you.

Koala Insulation did our basement. They did a great job and were professional. I appreciate the communication and patience with our project as plumbers and inspections fell behind schedule. Koala insulation, however, showed up when promised and finished as promised. They did a great job in the application of foam. We had a multitude of wires in the ceiling, mini-split air conditioning on the wall, and they were careful to cover it all. They cleaned up after the job and finished in a timely manner. I'd be happy to use them again.

Koala was the first company I called and I didn't know much about how spray foam worked. Austin was very helpful in explaining the concept and spent quite a bit of time on the phone with me. He event gave me a rough estimate over the phone. After calling a couple of other companies who never responded I had him come out to see the house in person in order to confirm his quote and make sure all the attics were accessible and spray foam would work. After seeing the house he confirmed the quote and we eventually scheduled a date. Before the installation day I asked him for a written estimate/contract. We boarded our dogs and I had my wife and son stay in a hotel for the 2 installation days. First day (removal) the guys showed up about an hour late. They worked hard all day but still weren't quite finished when I had to leave for the day. They said they would come back the next morning to finish in time for the installation. But then they also wanted to leave a giant bag of insulation in my garage for several days until they could get around to it. Said they had to get to their next job. Told them no, they needed to take it. Have to finish 1 job before you can move on. A little late the next day but they showed up and finished the removal. Now I will say, I have high expectations for any work done to my house. The removals guys were nice and cleaned up after themselves but some of the work in the attic could have been a little better. Left some of the removed items.
Installer showed up and i showed him everything and he got started. Estimate said the insulation would be 5.5" thick (nominal average) on the ceiling and 3.5" on the walls. This made complete sense as that is the depth of the bays created by the 2x6 and 2x4 lumber so my expectation based on that and other installations I had looked at online were that the bays would be filled with the variation coming in to play on the expansion of the foam. The R value of this foam is 3.8 / inch. When he was done and went and looked and found that the coverage was no where near filling the bays. Generally it was about 2.5-3.5 inches over about 95% of the ceiling and in very few areas was it even close to 5.5. I brought this to the installers attention and asked if it was done expanding. He said yes and when I showed him what I was talking about, he said he had been doing it for 13 years and this was how he always did it. He had me talk to the owner (Austin who did the estimate). He kept telling me it was nominal average and because they did 8-10 inches at the soffits it made up for it. That's not the way averages work and it's not the way insulation works. We went back and forth and I told him i simply wasn't happy and it needed to be fixed to match the contract. Paid most of the cost, but held back 20% until it was done.
They came out this week and the installer was still telling me it was thicker than i thought. Said I should stick a ruler in there to see. Well, I happened to have a 6" steel ruler handy (because I had already done that) and proceeded to show him the 1-3 inch measurements. He resprayed a second coat over the entire are and it ended up being the way it should have been in the beginning.

I called to have old attic insulation removed and new insulation blown in to replace it. Austin the owner gave me a competitive price and was prompt responding to me. His crew was very courteous and respectful while doing the work. They did everything asked of them. They arrived on time and did the job professionally. They also went out of their way to make sure everything was clean. I would highly recommend this company.

Austin was great from the estimate to finishing up the job. We've been having issues with moisture in the upstairs closets mostly due to a lack of insulation in the attic. I had some quotes from other contractors and Austin's price was right with the other guys. He was able to come out the next day to start the project. Both guys were very knowledgeable and answered all of my million questions. They were respectful of my home and did a thorough cleaning after they finished spray foaming. I would highly recommend these guys!

What Does Blown-In Insulation Cost in South Atlanta?
Blown-in insulation is one of the more affordable ways to upgrade home comfort, and the final investment comes down to a handful of factors.
Pricing comes down to:
- Installation effort: Tight access, extra prep, air sealing, or removing old insulation adds time and labor.
- Home and attic size: Larger spaces simply take more material.
- Insulation type: Cellulose and fiberglass carry different material costs.
Whatever the scope, the upgrade works in your favor over time: better attic coverage means less heat loss and lower heating and cooling bills.
Before you budget, check on incentives: many state and local governments and utility providers offer rebates that help bring the net cost down. Every home in South Atlanta is unique. For an accurate estimate tailored to your property and goals, contact the team today to schedule a free assessment.
Is Blown-in Insulation Better Than Rolls?
In most attics in South Atlanta, yes. The advantage is coverage: blown-in material forms a seamless, continuous layer that conforms around framing, wiring, and plumbing, where rolls (batts) leave seams and voids. Small gaps sound trivial, but they translate into drafts, hot and cold rooms, and lower real-world R-value.
How Much Blown-In Insulation Do I Need?
It depends on the attic’s square footage, the depth required, and your location on the climate map below. Colder climates call for thicker attic insulation to limit heat loss, while warmer climates need sufficient depth to block heat gain, so the recommended R-value varies by region. From there, attic size and target R-value determine the material needed for consistent coverage. South Atlanta falls in IECC Climate Zone 3A (warm-humid), where DOE and ENERGY STAR guidance calls for attic insulation of roughly R-30 to R-60.
Rather than estimating, professional installers work from climate-zone guidelines, your existing insulation depth, and manufacturer coverage charts. That approach matches depth to the recommended R-value for the region, builds in allowance for settling, and prevents the coverage gaps that undercut performance. Check the diagram below to see how recommended attic levels change across regions, and why the right depth here is not the same as somewhere else.
