Insulation in Windsor

What we find in Windsor attics

Windsor's climate is the outlier. Heating loads are the lowest in the province, so the winter payback on an attic upgrade is genuinely slower here than it is in Sudbury — and anyone who tells you otherwise is selling. What Windsor does have is the province's hardest summer: a hot, humid stretch where an under-insulated attic pushes an air conditioner to run all day. The same work that keeps heat in during January keeps it out in July, and in Windsor the July half of that sentence is the one that pays. The housing itself is heavily post-war, much of it built for the auto plants, with shallow attics and empty wall cavities.

Getting a crew to you

Windsor is on the southwest run and is booked by appointment. It is the longest drive we make in the south, so dates are grouped rather than taken one at a time.

Typical lead time: By appointment, grouped with southwest dates. Nothing about the rebate changes with distance — the programme is province-wide — but the diary does, and autumn fills before anything else.

What the attic stream pays

No energy assessment, one measure, and the tier set by the depth we measure before we start.

Amounts are set by Enbridge Gas and Save on Energy and are quoted from the programme pages — attic stream, assessment stream — checked September 2026.

What we will tell you about your house

• The measured depth, taken at the joist rather than at the hatch.
• Which tier that puts you in, and the dollar figure with the fifty per cent cap applied.
• Whether the soffits are blocked, because deep insulation over blocked soffits causes frost.
• Whether the bath fans vent outside or into the attic.
• If you are already over R–35, that the attic stream will not pay — and what is still worth doing instead.

You get the depth, the tier, the figure and the photographs whether or not you use us.
