Residential spray foam insulation in Morinville depends more on when a house was built than on anything else about it, because with about 47% of the stock predating 1991 this town holds two populations of house in roughly equal number and they do not want the same work.
Telling which one you have without a drawing
Three things settle it quickly and a homeowner can check all of them. Whether the basement wall is poured concrete or block, because block belongs to the older half. Whether there is a sheet of poly behind the drywall, which is a marker of the later decades. And whether the attic hatch has a seal on it at all. None of that requires a specialist, and together they place a Morinville house on one list or the other before anybody arrives.
Why a neighbour's experience may not transfer
This is the practical difficulty of a town built in two parts. Somebody a few streets away has had work done, it produced a large change, and it was the right work for their building and not for yours. The reverse also happens: a household on the newer side hears that the job is not worth doing because a neighbour on that side saw little, when the item that would have helped them was never on the quote. Advice moves around a small town faster than the reasoning behind it does.
What a house from either half is actually asking for
On the older side the sequence is the ceiling plane first, then the junction at the foundation, then whatever the additions have left behind. On the newer side it is a short list of specific places where an otherwise continuous envelope is likely to be interrupted, and it is checked rather than assumed. Both are real jobs, the second one is smaller and cheaper, and pretending they are the same job is what produces disappointed households on one side and overspending on the other.
The years on the boundary are their own case
A house built in the years either side of that line is the hardest one to advise on, because it may have been built to a standard that was changing while it was going up. Those houses need looking at rather than dating, and it is worth saying plainly that a Morinville property from that period gets a longer first visit than one clearly on either side of the divide. Guessing is what produces a quote that has to be revised.
Residential Spray Foam Insulation Morinville: Common Questions
How do we know which half we are in? Foundation material, whether there is poly behind the drywall, and whether the attic hatch seals.
Will we get the same result our neighbour did? Possibly on a different kind of house. The work that suits one half suits the other poorly.
What if our house was built right on the boundary between build eras? Then it gets looked at rather than dated, and the first visit takes longer.
