Attic insulation in Saint-Colomban
Saint-Colomban, whose first lots were granted in 1819, soon followed by Irish and Scottish settlers, became a city in 2010. Eighty-four homes in a hundred there are single-detached houses, and Isolation Cornerstone insulates their attics: the visit is free.

What the attic says from below
When the insulation is thin, packed down or uneven, heat passes right through and snow melts on the roof. The water refreezes at the eave as an ice dam. Warm air leaking through the ceiling brings moisture: vapour condenses on the roof deck and mold sets in on the wood.
From below, that looks like an upstairs bedroom that won’t warm up, or a stain on the ceiling. See also our page on attic ventilation.

Hi! Pick a question and we’ll answer right here.
Choose a question
- Which goes in first, the insulation or the baffles at the soffites?
- The baffles. Each soffite gets its own after the ceiling air leaks are sealed, and the insulation is blown in last, so air can keep flowing under the roof.
- Is it better to blow new insulation over the old rather than strip it all out?
- Depends on what is underneath. A blocked soffit or warm air leaking through the ceiling would stay hidden under the new layer, so Isolation Cornerstone fixes those first, then blows. Vermiculite is never covered over: it comes out first.
- Is the visit for the quote really free?
- Yes. Isolation Cornerstone comes to look at the attic at your address and gives you a written quote, at no charge and with no pressure.
