Anthony and crew where awesome 👏! We had them out to seal, add more insulation & install an attic fan. Anthony explained everything to me in detail. The crew were very neat and professional & the attic looks great! Hopefully it will translate to a much more comfortable upstairs. Thank you 🙏🏼 Kaola !!!

Koala insulated exterior walls in a kitchen and ceiling in the kitchen addition. It was done on time at a very reasonable price. The process was well explained. Work space was well cleaned after work and wall patched well. I really like the result. I would use this company in the future. The crew was very nice 👍

These guys are fantastic. I needed my crawl space and attic insulated badly in my 1940s home. They gave a very detailed estimate with lots of photos, talked through concerns, etc. My service was scheduled during a blizzard, and the crew went above and beyond to make it as easy as humanly possible to get my house up to code. They did spray foam + plastic in the crawl, full air sealing and blown in in the attic. Great experience. Tyler and Anthony communicated promptly every step of the way.

I am extremely hard to please when it comes to construction. Some would call me very demanding.
I was thrilled with the job that the team of four people did at my home today - the foreman, Anthony, to Pete, who sprayed the foam while Raul and Tyler how blew cellulose into the attack. They worked their tails off for eight hours, never stopping for a rest. I was super impressed. Not only did they do good work, but it was obvious that they wanted me be completely satisfied, And they succeeded. Everything was taped off perfectly, so that there was no overspray. It was all done, they cleaned the entire space as though their life depended on it.
I thought the cost of the job was very fair given all they had to do and the way they did it.
I wholeheartedly recommend them.

Great work by a local company. From estimate to final work performed, the staff were great and the job was handled to my satisfaction. I highly recommend Koala if you need your house insulated

This is a first class outfit. Always polite and on time. I had a small crawl space to insulate and needed R30 so foam was my only real option. Not the best of working conditions since the space was a little tight but the guys got it done just as well. If you need insulation work done I highly recommend them.

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.
