Blown-In Insulation in Markham: Cost, Benefits, and Where to Buy

Intro:
If you live in Markham or anywhere in the GTA, chances are your attic isn’t insulated to the current Ontario Building Code standard of R-60. One of the easiest and most affordable ways to upgrade is with blown-in insulation. But how much does it cost, what are the benefits, and where should you buy it? Let’s break it down.

What is Blown-In Insulation?
Blown-in insulation uses either fiberglass or cellulose loose-fill material that is spread evenly across your attic floor using a blowing machine. This method quickly covers all gaps and hard-to-reach areas, making it more efficient than batts or rolls.

Average Cost in Ontario (2025)

• Material cost: $15–$20 per bag for cellulose, $55–$75 per bag for fiberglass.

• Installed cost: $1.35–$1.90 per square foot depending on attic size and accessibility.

• DIY option: Rent a blower and buy insulation bags directly for significant savings.

• ✅ Meets or exceeds Ontario’s R-60 requirement.

• ✅ Reduces heating bills by up to 30%.

• ✅ Quieter, more comfortable home.

• ✅ Fast installation — most attics done in a few hours.
