Spray foam insulation cost in Carstairs is worked out the same way as anywhere else, by the board foot, and there are two things about this town that genuinely move the number in the buyer's favour.
An empty house is cheaper to work in than an occupied one
Most residential quotes carry hours that have nothing to do with foam: protecting rooms that are in use, working around a household, staging the job so a family always has somewhere to be, and stopping at a reasonable hour. A house that is empty from eight until five needs far less of that. The crew has the building, the masking is simpler, and the work runs without interruption. It is a real reduction in the labour side of a Carstairs quote and it is worth asking to have priced that way rather than assuming it has been.
Being in the corridor means the travel line is small
A great many pages on this site have to talk about distance, because most of Alberta is a long drive from a crew. Sitting between Calgary, Airdrie and Olds, this is not one of those places. Mobilisation is a minor item here, which has a useful consequence: when two quotes on the same Carstairs building differ, the difference is almost entirely product, depth and preparation rather than who happened to be working nearby. That makes it a good market to compare properly in.
What actually separates two quotes on a house of this age
On the newer stock it is usually depth and how much air sealing is included, because the shell is sound and the work is a defined list. On the older village houses it is preparation: what has to come out, what has to be protected, and whether the assembly can be reached at all without opening something. A quote with no preparation line on an older house has not been thought about, and it is the line that most often turns a cheap number into an expensive job halfway through.
What to have settled before anyone visits
Three things speed a visit up and make the number firmer. Know the build date, because it decides which of the two local stocks the house belongs to. Know whether the basement is finished, being finished, or staying as it is, because that changes both the scope and what has to cover the foam. And know which single complaint you want solved, because a household that can name the room and the time of day it happens gets a far more specific answer than one asking to be told what the house needs.

Is it cheaper because we are out during the day? On the labour side, genuinely yes. Ask to see it reflected in the quote.
