Limestone and brick century houses with nothing at all in the walls.
The older Guelph core is stone and double-brick, built long before cavity insulation existed. Solid masonry walls cannot be drill-and-filled — there is no cavity to fill — so on those houses the honest answer is that the attic, the rim joist and air sealing are where the money is, and interior or exterior insulation of the walls is a renovation rather than a retrofit. We will tell you that on the phone rather than after a site visit.
Guelph is a scheduled run rather than a same-week booking. Worth asking when the next block is heading west.
Typical lead time: Ask for the next block. Nothing about the rebate changes with distance — the programme is province-wide — but the diary does, and autumn fills before anything else.
No energy assessment, one measure, and the tier set by the depth we measure before we start.

| R–12 to R–25 — about 4 to 8 inches | R–50 | $1,000 |
