  • FAQ

Got any questions? We’ve got answers.

Blow-in insulation (also called loose-fill insulation) is ideal for retrofitting existing homes because it can easily fill irregular spaces and hard-to-reach areas without major structural changes. It provides excellent thermal coverage, reduces air gaps, and improves overall energy efficiency. It also helps with soundproofing and can be installed relatively quickly with minimal disruption. Additionally, it’s a cost-effective way to upgrade insulation in older homes.
A professional energy audit evaluates how your home uses and loses energy. Using tools like thermal imaging and blower door tests, experts identify problem areas such as air leaks, poor insulation, or inefficient systems. This helps you focus on the most impactful upgrades first—saving money and improving comfort. Instead of guessing, you get a clear, prioritized plan tailored to your home’s needs.
Batt insulation is best suited for open, accessible areas with standard spacing, such as wall studs, floor joists, and ceiling rafters. It’s commonly used in new construction or major renovations where walls are exposed. It’s a cost-effective and straightforward option when cavities are uniform and easy to reach. In both residential and commercial buildings, it’s often installed in walls, attics, and floors.
Air sealing involves identifying and closing gaps, cracks, and leaks where air escapes or enters your home. Key steps include inspecting problem areas (like attics, windows, doors, and ductwork), sealing leaks with caulk or foam, and ensuring proper ventilation is maintained. It’s recommended before adding insulation because insulation alone doesn’t stop airflow. Sealing first ensures the insulation performs effectively, maximizing energy efficiency and indoor comfort.
