bat and poly insulation services in St Catharines

Great Northern Insulation's St. Catharines branch is a trusted partner for homeowners and builders in the Niagara region. Founded in 1987, our St. Catharines branch was originally known as Moore Insulation. Over 30 years, we've established a strong reputation for exceptional service and expertise in insulation and energy efficiency solutions.

In 2022, Moore Insulation joined the GNI Management Group Inc. family, becoming Great Northern Insulation's St. Catharines branch. This merger allows us to offer the combined strength and resources of Canada's largest insulation services provider, while still maintaining the local focus and relationships we've built with our community.

Led by General Manager Rick Bartel, the St. Catharines branch serves homeowners and builders in St. Catharines and the surrounding areas, including Niagara Falls, Niagara-on-the-Lake, Welland, Port Colborne, Fort Erie, Thorold, Pelham, Lincoln, and Grimsby.
