Isaac and Dillon were a pleasure to have in our house. They took extra care to protect our floors and belongings while they were working and made sure to double and triple check their cleanup throughout the house.

We got plenty of documentation of the work they performed in our attic (we certainly didn’t want to crawl up there to verify) and they were great at communicating what they were doing before they did it, and what they found and accomplished after they finished.

Kayla was the woman who quoted the work, she came by for the initial consultation and then came back this morning before Dillon and Isaac to perform some tests and make sure we got any questions answered. Everyone we have interacted with at Koala has been wonderful

This review is specifically for Kayla at Koala Insulation. Our initial experience was Kayla was fantastic. She was extremely knowledgeable and provided a thorough overview of our attic spaces and insulation needs. However, even more appreciated was one year later, we got a completely outrageous estimate from our pest company, and we had Kayla come out and take a look at our attic space and reassured us that we did not need to pay for unnecessary services. I would recommend Koala Insulation to anyone due to Kayla’s outstanding customer service!

Isaac ( the installer) and his helper did a great job. They were very professional, explained everything and cleaned everything up perfectly. I had a friend who used them and I’m grateful for her recommendation.
They insulated my attic, but they also do other parts of the house. This is a woman owned company that I was glad to support.

They were on time and helpful. Did a good job although communication with Cesar was challenging as he spoke little English. They tried to mask off where they were working, but I still had a LOT of dust to clean up afterward. Overall satisfied!

If I could give more than 5 stars to the amazing crew & company I would. I’m so impressed by the professionalism, right from the time of the evaluation & very fair quote, given by Kayla, to scheduling & the final result. I can’t say enough about the crew who did the job! Oscar, Matthew & Jacob were absolutely incredible. They arrived on time, took on what I thought to be a very daunting task of upgrading the entire space, yet made it look like an absolute breeze. They worked together like a dream team, super efficient, professional & paid such attention to detail. I really appreciated their final touch of cleaning up all surrounding areas afterwards. It is rare to find a team and company who comes through like they did. As an interior designer, I will from now on be utilizing Koala Insulation of Denver North for all of my home remodels. I highly recommend, don’t even think twice!

How much does insulation cost in Aurora?

Blown-in attic insulation in the Aurora area typically starts at $1.60 per square foot, so a standard 1,500 sq ft attic usually lands in the $2,400 to $4,000 range. Spray foam costs more per square foot but seals air leaks at the same time. Final price depends on attic size, the R-value you’re starting from, and the insulation type. Every quote is written, itemised, and free.

What type of insulation is best for a Aurora attic?

For most Aurora homes, blown-in cellulose over the attic floor combined with air sealing gives the best result for the money — it fills gaps around joists and wiring that batts leave open. Spray foam is the better choice when you need to air seal the roof deck itself or convert the attic into conditioned space. We recommend a type after inspecting your attic, not before.

What R-value do I need for an attic in Aurora?

Aurora sits in climate zone 5B along Colorado’s Front Range, where the Department of Energy recommends R-49 to R-60 for attics. Most Aurora homes built before 2000 come in around R-19 to R-30, which is well short for our cold, high-altitude winters. R-49 is also the level most Colorado utility rebate programs look for. We measure your current R-value during the free evaluation and tell you exactly where you stand.

What areas around Aurora do you serve?

Koala Insulation of Aurora serves Aurora and the surrounding Denver area across Colorado’s Front Range, from the south Denver suburbs through the Colorado Springs region. Not sure if you’re in range? Call (720) 824-6030 and we’ll confirm in a minute.

How long does the job take, and do I need to leave the house?

Most attic insulation jobs are finished in a single day, and you can stay home for blown-in work. Spray foam requires you to be out of the house for roughly 24 hours while it cures. We’ll tell you which applies before we book.
