Professional Air Sealing for Energy Savings

Air sealing is a crucial step in optimizing your home’s energy efficiency. Even the best insulation can underperform if your home has air leaks. These leaks allow conditioned air to escape and unconditioned air to enter, forcing your HVAC system to work harder and increasing your energy bills. Air sealing involves identifying and sealing gaps, cracks, and leaks around doors, windows, and in attics and basements, preventing energy loss and ensuring your home remains comfortable year-round.

Koala Insulation specializes in air sealing services that complement your insulation. Our team uses advanced techniques and high-quality materials to create an airtight seal, ensuring that your home’s insulation performs at its best.

Why Air Sealing is Essential

Reduced Energy Bills: By eliminating air leaks, air sealing reduces the workload on your heating and cooling systems. This leads to lower energy consumption and significant savings on utility bills.
Improved Comfort: Sealing air leaks eliminates drafts and creates a more consistent indoor temperature, making your home more comfortable throughout the year.
Enhanced Indoor Air Quality: Air sealing helps prevent pollutants, allergens, and moisture from entering your home. This leads to healthier air quality and reduces the risk of mold growth.
Better Insulation Performance: Without proper air sealing, even the best insulation materials can be less effective. By sealing gaps and cracks, air sealing ensures that your insulation can work at its full potential.
Environmental Benefits: Lowering your home’s energy consumption by reducing air leakage helps decrease your carbon footprint, contributing to a more sustainable and eco-friendly home.

I hired Koala to remove all the drop in insulation in the attic of my 1968 home and they did an amazing job! Their communication was great, and once their team got to work on the job, they had it fully finished and cleaned up within 2 days. I am excited to be working with Koala again in the near future for spray in insulation and crawl space mitigation.

I booked a very specific date a few months ago and Jared and the team committed to that date, understood the importance of the winter break schedule. My job was unique and had some challenges, but their communication was fantastic. The guys showed up on time and the job was done in a timely manner and they cleaned up perfectly afterwards. I was also really pleasantly surprised by the finished look! Insulation has come a long way. The crew were very respectful and polite. 1000% recommend 🌟🌟🌟🌟🌟

Jon was excellent, and did a perfect job. Courteous, Professional, showed up on time and cleaned up after. Added to the fact I was pleased to know he is a Military Veteran, serving our Country in the US Army. We like to know we’re hiring Contractors that employ our Veterans.
Koala Insulation had the best price around and pleased w/the completion of the job they did today. I’d recommend them!

Jon & his team are very friendly, professional, & invested in performing the best job possible. They cleaned up after themselves after blowing in fiberglass to bring me up to a R49 value. While installing batting in my crawlspace they identified an issue which needs repair & remediation & put me in contact with a remediation company. Top notch all the way around!

So easy! I had Bryant come out and give me a quote. He was very personable and honest. Got lucky to get installation done quickly and efficiently. Jon and Uzman (spell?) were my installers. Very kind and clean! Victoria has been helping me with all the rebates and paperwork to be done! Very professional and friendly! Have already recommended Koala to two people! Excellent work!

The whole process from getting a estimate to coming and doing the work was great. They were very friendly and professional and knowledgeable about my issue I was having. The crew that came and performed the work were very friendly . They provided me pictures of they completed work. I would definitely recommend this company.

Jared and Jon were amazing to work with. Fair prices, honest work. Went above and beyond to help us with our attic and crawl space. Highly recommend.

We are very pleased with every aspect of our service from Koala Insulation. Jared came out and inspected our attic, we thought we may have water damage due to roof damage from the recent storms, but he advised we did not. He was very professional, friendly & on time. We greatly appreciate his honesty!!!

We asked for quote to upgrade our insulation. Jared provided the quote & advised that TVA currently has rebates so the cost is basically half price during this time. We scheduled the date for the upgrade insulation and air sealing to be done.

Jon G. arrived right on time for the installation. He was also very professional, friendly & did a great job of cleaning up afterwards. He provided us with pictures of the work that was completed. He also went back over the TVA rebate program & how it works.

The temperature has been much higher the past week and we can tell a big difference in the house already. We are extremely happy with Koala Insulation!

Jared and his team perform exceptional work, dedicating themselves to a job well done. You don't see that type of work ethic often these days, especially in areas experiencing rapid growth with cheap labor and workers who hastily complete jobs. We're so glad we went with Koala Insulation of Nashville for our crawlspace encapsulation and attic insulation needs. Extremely reasonably priced services in comparison to competitors in this area. We recommend this team without any reservations.

These guys are fantastic and did a great job for us with our attic insulation! The spray foam has already made a significant improvement to our comfort and keeping the HVAC from constantly running. Looking forward to seeing our utility savings this summer! Thanks Brandon and the entire Koala team for an awesome experience!

BJ and John arrived exactly on time and ready to work. They were obviously experts and actually also found some defects in my HVAC ducts which they took pics of and pointed out so I could get them taken care of later. They installed a ducted dehumidifier in my crawl space and it is a beauty! I sincerely appreciate their work and would absolutely recommend Koala to anyone.

Zach did a great job today. And Jared has been great to work with as well. This is the 3rd time we’ve used these folks as we’ve added 2 additions to our home and every time they have been wonderful to work with. They communicate with you throughout the entire process, show up when they were scheduled, prepped the work area to avoid creating a mess, worked efficiently to accomplish the job and cleaned up their work area upon completion.

I can’t say enough about the quality of their work, the friendliness of their people and their professionalism throughout the entire process. Great job guys! Thanks for taking good care of us!

I received such great service during my first job of attic insulation, I once again hired Koala Insulation to insulation the garage. Once again, I was impressed by the quality of service received from Victor and Gabriel. Arrive on time, worked diligently, and left the area as clean as when they arrived. This company deserves your consideration for any and all insulation needs.

Had R49 blown in, great job and place was left spotless.. Jon is a great guy and truly cares about the work he is providing. I will definitely use this company in the future for add ons to our home.

Thanks Koala Insulation of Nashville for the excellent job performed today. Cody and Braxton arrived right on time and wasted no time getting set up for the job. Didn’t take long to complete the work and made sure to clean up after they were done. Then Cody had photos to share of the work completed. I would highly recommend this company for insulation work!

BJ Hardy and his crew did an amazing job removing our old, very old insulation and installing new spray foam in the attic. They were very communicative the whole way and it was like they were never in the house! Great work and professional!!!

Koala Insulation of Nashville came out to remove our old insulation and replaced it with new blown-in fiberglass. The crew; Cody, Jackson, Zach, and Ronnie were very professional and friendly. They explained everything they were doing, problem solved and communicated well with us, and overall did and excellent job. They removed old plywood, air sealed, and installed an attic fan in addition to the blow in. Our attic is night and day from the old, sunk down insulation to the now new fiberglass at R-38. We look forward to having a more comfortable feeling home and for our heat/AC unit to work less. Thank you Koala Insulation!

Below is the email I sent to the company:

"I am extremely unhappy with your services.

I had to pick up dozens of screws from where the ceiling was removed off of my floor.
A piece of the ceiling was left up.
The lights were not put back up and most were left on my counter tops.
One of the lights were left outside and was rained on overnight making is unusable.
Antother was light was broken, with glass in my sink.
Not all of the blown in insulation was removed.
The foam insulation was not sprayed in the overhang area as was quoted to me by the salesman.

(Photos attached for reference.)

This is my home, the place where I live and sleep. I have never, ever had my home left such a mess after having work done. It is excedingly distrespectful!

I now have to hire someone to come hang the new lights that I have to purchased to replace the damaged ones."

Then when the electrician came out he discovered that there was a live wire hanging over my bed where they took that light down.

I reached out to Koala via email. JD called me and I was at work and I explained that the best way to reach me was via email. I have not heard from anyone at the company since.
