Amazing experience. Koala came out in the blistering heat to help assess our very old attic insulation and not only gave a quote but spent the time answering our questions and educating us on the science behind the process. We had a second floor that was unlivable in the summer months for years. Just a few days after the new R-60 insulation our second floor is easily 15-20 degrees cooler even in the hottest day. I couldn’t be more greatfull for the prompt professional service and installation. Would highly recommend! Thanks Joe and team!!

Josh and CJ were great. They were right on time, efficient, professional, and Josh answered all of our questions. I especially appreciated Josh’s knowledge of the end-to-end process for Koala (and Ameren!).

This company does quality work! We have a 1930s house with a big squirrel issue in the attic. In addition to other repairs, we needed old insulation removal, enzyme cleaner applied, air sealing, and new insulation. They did all of this and took pictures every step of the way to update me. These guys had a very long day, but were extremely nice and hard-working. If I had to go through this process again, this is who I’d pick in a heartbeat .

We recently had Koala Insulation blow insulation into our attic and install a Draft Master, and the difference has been noticeable immediately. They also sprayed Attic Fresh throughout the attic, and it honestly made the whole space feel like a brand new build.

Upstairs is already feeling more comfortable, and you can tell the home is holding temperature better. The crew was professional, courteous, and took great care throughout the entire process. They explained everything clearly, worked efficiently, and left everything clean when they finished.

Overall, a great experience from start to finish. I’d definitely recommend Koala Insulation to anyone looking to improve their home’s comfort and energy efficiency.

I found Koala Insulation through the Ameren/Spire Pays program. We needed a lot more insulation up in the attic to help with our comfort in the house. Josh and crew came on time and were great to work with. They took care working in the house. They put down plastic on the floors where they were running their tube. At one point their tube sprung a leak outside in the yard. They took the time to vacuum up all the stuff that blew into the yard to make it look good. They answered all my questions and even made a few suggestions that I could do to help with my attic in the future. I would highly recommend them.

What does insulation cost in Ballwin?

Insulation pricing in Ballwin is driven by the work your home actually needs. Attic or wall size, the insulation type you pick, blown-in, fiberglass, or spray foam, and the scope of prep all move the number. Pulling out old material and sealing gaps before we add new insulation can factor in too. You may be able to claim rebates through Ameren and other local utility programs, and we’ll point you to what applies. Book a free evaluation and we’ll give you a clear, written quote for your Ballwin home, with no pressure.

Which insulation is best for homes in Ballwin?

For the typical Ballwin home, blown-in over the attic floor plus sealing the gaps is the sweet spot, particularly with ice storms in winter and heavy humidity in summer. Blown-in fills the gaps around joists and wiring that batts leave open. Where you need to air seal the roof deck or condition the attic, spray foam is the stronger option. We recommend a type after we’ve been in your attic, not before.

What’s the recommended R-value for Ballwin attics?

Ballwin sits in climate zone 4A, where the U.S. Department of Energy recommends about R-49 to R-60 for attics. It’s common to find the 1970s-to-1990s subdivisions across Ballwin sitting at only R-19 to R-30, well short of the target. During the free evaluation we check your current R-value and tell you how far off you are. Bringing an attic up to spec can also qualify for rebates through Ameren and other local utility programs.

What areas around Ballwin do you serve?

We cover Ballwin along with neighboring towns such as Ellisville, Manchester, Chesterfield, Wildwood, and Town and Country and the communities around them. Unsure if your street is covered? Dial (314) 756-5661 and we’ll check in a moment.

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

Blown-in attic work is usually a one-day job, and you’re welcome to stay in the house for it. If the job is spray foam, you’ll want to be away for about 24 hours while it fully cures. Either way, we’ll walk you through the timeline before booking your Ballwin job.
