Insulation is one of the most important—yet often overlooked—components of a healthy, energy-efficient home. Proper insulation helps regulate temperature, reduce energy bills, and improve overall comfort year-round. At Hymask Construction Group we offer professional residential insulation services, including expert blown-in insulation installation to homeowners across Simcoe County and the District of Muskoka.

Whether you’re insulating a new build, topping up existing insulation, or upgrading an older home to meet modern energy standards, we’re here to help. We use high-quality materials and proven techniques to seal your home’s thermal envelope, keeping the cold out in winter and the heat out in summer.

Blown-In Insulation: Fast, Effective, and Ideal for Ontario Homes

Blown-in insulation (also known as loose-fill insulation) is one of the most efficient ways to insulate attics, walls, and hard-to-reach spaces. It creates a seamless, blanket-like layer that fills gaps and voids where traditional batt insulation can’t reach. Blown-in insulation is perfect for:

Older homes with settling or thin insulation

Boosting R-value in existing attics

Sealing small cracks and air leaksIncreasing energy efficiency and indoor comfort

Our team handles the full process—from assessing your current insulation levels to recommending the right materials (fiberglass or cellulose), performing a clean, efficient install, and making sure everything meets Ontario’s building and energy code requirements.
