Your North York Insulation & Fireproofing Contractor

North York's mid-century bungalows around Bathurst Manor, Willowdale, and Bayview Village are prime candidates for attic top-ups and basement spray foam — most still have original R-12 attic insulation from the day they were built. Northstar's North York crews run several attic jobs a week.

Large lots and finished basements are the North York norm. We focus on rim-joist sealing (the biggest air-leak source in homes from this era) and removing settled vermiculite from attics before topping up with blown-in cellulose to R-60.

North York tip

If your North York home was built before 1990 and the attic hasn't been touched, assume R-12 or less — a top-up usually pays back in under five winters.
