Professional Air Sealing for Energy Savings
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.

Xan was great with the assessment, detailing out the issues we had and the process going forwards. He helped us navigate the rebate system and the price point was great as well. Once we had a separate issue dealt with, we were able to book very quickly and his crew were timely and clean!

Great friendly service with Xan and his installers. Had blown in attic insulation added as well as spray foam done. Both trucks well equipped, clean. Took every effort to cover work area and clean up after the job was complete.
Fair pricing and quick service and took the time to explain work thoroughly and provided before and after pictures. Will use his services again on other properties.

One of the most recognizable forms of insulation. Batt comes in large rolls or pre-cut sections that are typically pink or yellow in color. These are installed in sheet form and laid out between the studs in walls, floors, and attics.
Insulation Removal Services
If you’re experiencing moisture damage, pests, mold, diminishing efficiency, or other problems, we’ll remove existing insulation, and sanitize and deodorize the areas.
Solar Attic Fans
Solar attic fans turn your attic into a livable space by pushing hot air out and pulling cool air in. Our fans use solar energy to keep your attic at a comfortable temperature year-round.
Blown In Attic Insulation
Consisting of small pieces of insulation, this type of insulation can quite literally fill every nook and cranny of a space and create an uber-fluffy layer of effective insulation. Our technicians ensure your attic, wall and ceiling cavities are filled correctly and without gaps or voids.
Spray Foam Insulation
Spray Foam is a two-part product that is heated and then is sent through a hose into the stud cavity, where it hardens in a matter of seconds and creates a long-term barrier that keeps your home comfortable and energy efficient.
