If you get someone knocking on your door to look at your attic and is giving you a 8k bill to insulate it please call these guys. They are absolutely amazing. I got one of these energy companies trying to sell me a big package, I immediately looked companies online and found Koala and they game out within couple of days looked at my attic and gave me a quote within minutes of their visit. It was a fraction of the other one. I ended up doing air sealing and insulation as I didn’t need anything else! Steph was the inspector and he was very upfront and gave me different packages and didn’t try to upsell me! He told me exactly what I need and suggested things I might need but not required. Tyler and Woody did the insulation. They were here on time and were in and out within 1 hour! Super quick and even took pictures (which I requested) so I can see the before and after! Highly recommended this company, they are honest and professional!

Wonderful experience! Quick to set up a quote (Steph did great walking me thru the options!), setup the removal of old insulation, and then getting the new insulation. Devon and Kelton did a great job removing the old insulation. And Woody and Tyler did great putting in fresh insulation. So quick - and even on a hot day! Great to work with and highly recommend.

Had a great experience with Tyler and Martin. They were in-and-out in under 2 hours. Removed all the existing insulation and blew in up to R38, as well as a mold/bacteria spray to help with moisture. We are happy with the installation, service, and looking forward to the benefits of full attic insulation. Thanks, Koala Insulation, Tyler and Martin!

These guys are awesome. Very reasonably priced, we got several quotes and they were often 1/2 the price. Our technicians Tyler Martin and Austin Woods were respectful, professional, and adaptable. Our house is hard to find but they found it. And apparently there was a bird in our attic that we didn't know about, and it caused a bit of trouble, but didn't scare the technicians away. They got the job done anyway. We have very small attic entrances and they were able to squeeze through. We were shown photos of the completed work and they went above and beyond. They were good with our animals and very friendly. And they are getting us a rebate too. Highly recommend Koala Insulation 👍

I called Koala to assess the insulation in my attic. Steph returned my call and set up a time convenient for me. He kept the appointment on time, entered my attic space and reported the installed insulation was in better than normal condition requiring no additional work. I asked about attic fans and he provided information about their benefit. I requested installation of two fans according to his recommendation. The installers came at the agreed date and performed the installation. All contacts with Koala were professional and polite with quality work through installation. I gladly recommend them to anyone.

We had an excellent experience with Koala Insulation. When Steph first came out for a quote he was knowledgable and gave insightful recommendations. From spray foam installation start to finish, Terrell, Dylan and Juan were professional and cared about doing the job right.
They took the time to explain the process clearly, answered all my questions and made sure I felt confident about the work being doing. The installation itself was smooth and efficient (finished quicker than originally quoted$l) and the left everything clean afterwards.
I highly recommend Koala Insulation if you’re looking for reliable, skilled professionals who do quality work.

Fast and efficient work! Steph came out and did a thorough inspection of my attic. 13 inches of insulation is current code...I had 3 inches! (And a nearly $600 electric bill for the month of January!!!)
The quote was very reasonable and TVA offers a $500 rebate for being compliant with energy standards.
Woody and Tyler came out and quickly got us up to code (and beyond!) Both were friendly, professional and efficient.
They answered all of my questions and provided me with plenty of pictures showing their work. I am extremely happy with Koala Insulation and would absolutely recommend them for your insulation service needs! Thanks guys!

Frequently Asked Questions
How do I know if my home needs new insulation?
Common signs include uneven temperatures between rooms, high energy bills, drafts near windows and doors, and an HVAC system that runs constantly. If your home was built more than 10-15 years ago, there’s a good chance the insulation needs an upgrade. We offer a free home evaluation so you’ll know exactly where you stand.
How long does a typical insulation installation take?
Most residential installations are complete in two to four hours, depending on the scope of the project. Larger jobs or full-home upgrades may take a full day. We’ll give you a clear timeline during your estimate.
What type of insulation is best for my home?
It depends on your home’s structure, climate, and specific problem areas. Spray foam works well for sealing air leaks and providing high R-values. Blown-in is great for attics and hard-to-reach spaces. Batt insulation provides reliable, even coverage for walls and floors.
How much can I expect to save on energy bills?
Results vary based on your home’s size, current insulation condition, and climate. On average, homeowners see a 15% reduction in monthly energy expenses, and some save up to 40%.
Is insulation safe for my family and pets?
The insulation products we use are safe, non-toxic, and meet all industry safety standards. Our installation process is clean and controlled. In fact, proper insulation actually improves indoor air quality by blocking allergens, moisture, and mold.
