Our Woodstock location has been insulating Southwestern Ontario and the Niagara Peninsula Region since 1980.  This experience has made us the insulation contractor of choice for residential, agricultural, commercial and industrial insulation projects.

Woodstock (Toronto)

 

"We live in an older home and recently had it insulated and air sealed by Great Northern Insulation. Since the work was completed, we’ve noticed a dramatic decrease in our heating and air conditioning bills, as well as much more comfort in our home. Dollar for dollar, proper insulation is an effective way to save energy."
