Newmarket has a genuinely split housing profile: a historic downtown with homes dating back well over a century, and newer family-oriented subdivisions built out over the last few decades as York Region has grown. Different construction eras, same underlying issue — attic insulation that was adequate when installed and isn’t necessarily adequate now.
Old Homes, New Homes, Same Blind Spot
Downtown Newmarket’s older homes frequently have minimal original insulation by today’s standards, sometimes with irregular attic spaces that were never designed with insulation performance in mind. Newer subdivision homes meet code at construction, but builder-grade insulation is a floor, not a ceiling — it settles and loses effectiveness over time just like older insulation, just from a different starting point.
Why This Summer Made It Obvious
This year brought some of the hottest weather Ontario has recorded in decades. Families with upstairs bedrooms that stayed hot well past sunset, air conditioners running non-stop without keeping up — that pattern points to the attic almost every time, not a failing HVAC system.
What to Look For
- Upstairs rooms that run noticeably hotter or colder than the main floor
- Energy bills that jumped this summer more than usual
- A home that’s never had its attic insulation checked, regardless of its age
- Ice buildup or uneven snow melt on the roof during winter
Get Ahead of the Fall Rush
Once the weather turns, demand for insulation upgrades across York Region climbs fast, with the busiest stretch running October through February. Booking a free inspection now means getting a spot before that rush and finishing any recommended work before winter arrives.
Programs like the Enbridge Home Renovation Savings program and the Canada Greener Homes Loan may apply to insulation upgrades depending on your situation. These change their rules often enough that we’ll confirm current details rather than quote a number that might no longer be accurate.
