Professional Air Sealing Services in St Louis
Air sealing is a crucial step in optimizing your home’s energy efficiency. Even the best insulation can underperform if your home has air leaks. These leaks allow conditioned air to escape and unconditioned air to enter, forcing your HVAC system to work harder and increasing your energy bills. Air sealing involves identifying and sealing gaps, cracks, and leaks around doors, windows, and in attics and basements, preventing energy loss and ensuring your home remains comfortable year-round.
Koala Insulation specializes in air sealing services that complement your insulation. Our team uses advanced techniques and high-quality materials to create an airtight seal, ensuring that your home’s insulation performs at its best.
Why Air Sealing is Essential
- Reduced Energy Bills: By eliminating air leaks, air sealing reduces the workload on your heating and cooling systems. This leads to lower energy consumption and significant savings on utility bills.
- Improved Comfort: Sealing air leaks eliminates drafts and creates a more consistent indoor temperature, making your home more comfortable throughout the year.
- Enhanced Indoor Air Quality: Air sealing helps prevent pollutants, allergens, and moisture from entering your home. This leads to healthier air quality and reduces the risk of mold growth.
- Better Insulation Performance: Without proper air sealing, even the best insulation materials can be less effective. By sealing gaps and cracks, air sealing ensures that your insulation can work at its full potential.
- Environmental Benefits: Lowering your home’s energy consumption by reducing air leakage helps decrease your carbon footprint, contributing to a more sustainable and eco-friendly home.

Nothing but great things to say! We were struggling with a very HOT 2nd floor in our home due to poor attic ventilation and old insulation that had settled over the last 20yrs. Nick, Nathan, Ryan, John and Claire were outstanding. Nick showed up on time for the assesment, was extremely knowledgable, provided tons of value/knowledge right out of the gate and never tried to 'sell' me once. We scheduled a date to have Ryan, John and Nathan come out and they followed suit. Courteous, professional and very clean from start to finish. We can ALREADY notice a 7+ temp degree drop upstairs from adding R-49 blow in to our original insulation, solar fan, soffit ventilation and radiant reflective barrier. 11/10 Highly Recommend!!

Koala Insulation was absolutely excellent to work with from start to finish. From the initial contact through completion of the project, their customer service and workers were personable, professional, and incredibly easy to work with.
I had a project that every other company I contacted told me was impossible and simply refused to take on. Koala Insulation was different. They not only said they could do it—they actually did it, and they did it with excellent quality and impressive promptness.
I couldn’t be happier with the results or with the entire experience. It’s refreshing to find a company that listens to the customer, takes on challenging projects, and delivers exactly what they promise. I highly recommend Koala Insulation!

Nate and team were fantastic. They spray foamed the attic and shared their expertise on portions of the project that I plan to do on my own. They were in and out and protected everything while they sprayed.

Koala provided outstanding customer service from the estimate to installation. Nick was very knowledgeable about what my attic required to be more efficient and Ryan and John showed up on time, didn’t complain about my sketchy attic, finished quickly and cleaned everything up. Very professional company that I highly recommend. Now I just need to plan how to spend all the extra money from my heating bill!
