Your Oakville Insulation & Fireproofing Contractor

Oakville is premium territory — Glen Abbey custom homes, Old Oakville heritage, and the new-build estates of Joshua Creek and Bronte Creek. Northstar's Oakville work skews to high-end retrofits and full new-build spray foam envelopes.

Oakville homeowners expect a contractor who treats their property with care: shoe covers, floor runners, daily site cleanup, and a foreman they can call. That's standard for every Northstar Oakville job, residential or commercial.

Oakville tip

Oakville's lakefront heritage homes often have stone foundations that benefit from interior closed-cell foam — fixes cold floors without altering the historic exterior.
