Your Bolton Insulation & Fireproofing Contractor

Bolton sits in Caledon's south end and has grown into a busy commuter community. Northstar serves Bolton with new-build spray foam packages, attic upgrades on 1980s–90s homes around Humber Lea, and rural property work nearby.

Bolton's mix of newer subdivisions and rural-edge properties means we often work on both ends of the spectrum in the same week — code-min spray foam packages on builder homes, and big retrofits on rural century homes.

Bolton tip

Bolton homes on the valley side can be exposed to strong winter winds off the Humber — closed-cell rim-joist sealing makes a noticeable comfort difference.
