"Why you should upgrade your home’s insulation"

According to the Department of Energy, "Space heating and cooling account for almost half of a home's energy use, making this one of the largest energy expenses in any home.”

As your home ages, your insulation begins to deteriorate - as do the seals around your windows, doors, and lights. Did you know that 50-70% of the energy used in your home consists of heating and cooling? By reinsulating your home, you can save money each month on your utility bill.

A properly insulated home is more comfortable, and the air will stay cleaner. Insulation and air sealing ensures that conditioned air stays inside your home. With poor insulation, your HVAC system works very hard to continuously condition air which seeps in. This air which seeps in is often very dirty and totally avoidable.

The best way to reduce your home's carbon footprint is by reducing energy waste through increased efficiency. According the the EPA, the #1 way to reduce your energy usage in your home is to improve the building enery efficiency through better insulation. Retrofitting can allow new and existing homes to upgrade their insulation.

Have you been in your home and wake up to birds chirping or your neighbor's dog barking outside? Maybe the weather seems louder than it should be. Insulation combats outside noises and also helps with reducing the amount of noise carried from one room to the other.

Better than excepted. Great job and they cleaned everything up. Plus, the new spray foam insulation is working great. Much Cooler and much quieter. The cost was reasonable. Great value for what they did.

I highly recommend this company. Friendly team!!!

The project started 4 days after they gave us a quote, and the price was below asking from the other companies. The crew called 15min when they were en route. They finished within the time they mentioned, I highly recommend this company. Friendly team!!!

Central West End

They will hear you out and make sure they get it right

The crew showed up on time, worked well, and cleaned up nicely. They went above and beyond on cleaning up some of the insulation that had been blown outside onto my back patio via the solar fan. There was a bit of confusion on whether I had ordered a batt for the back of the attic cover but the guys were happy to install it and had an extra on the truck. If things come up with this company, they will hear you out and make sure they get it right. Very professional. I waited two weeks to write a review and can honestly say I feel a major difference in comfort and humidity levels in my house. Can't wait to get my next electric bill to see how much it has gone down since my AC isn't running all the time.


Very responsive and courteous staff.

From quote to finish, very responsive and courteous staff. Installers took pictures and showed me the progress at each step. They made sure to clean up everything after they were finished. Very pleased with their work.

Koala insulation were incredible.

Koala insulation were incredible. From the estimator to the installers, they were polite, professional and efficient. Within hours of them installing the insulation and the solar powered attic fan our second floor was 10 degrees cooler. No more high energy bills and unliveable conditions on our second floor. Thanks to Koala we can enjoy the whole house no matter how hot it gets outside.

Benton Park

Thanks to Koala Insulation we can actually use our second floor!

Every part of the Koala Insulation process was incredibly smooth and professional. Gary arrived on time and was extremely polite and professional, immediately identifying our problem and laying out all options. He provided an immediate estimate for adding 16” of blown in insulation and a solar powered attic fan, explained the tax credits and answered all questions. Nick and his team showed up promptly at their install window; they were clean, courteous and efficient. The price was reasonable, the estimate was detailed, they were informed and professional and the results were immediate. Our second floor went from 85 in 95 degree weather, to a cool 72 in the same heat.

They were incredibly detail oriented and went above and beyond and repaired multiple air vents that were previously damaged.

Cannot say enough good things about my experience.
