Basement spray foam insulation in Stony Plain covers two quite different jobs, because a third of the housing here went up before 1991 and those foundations were built to a different idea of what a basement is for.
A basement built for storage and a basement built to be lived in
The older foundations in this town were poured or laid when a basement was where the furnace and the preserves went. Damp-proofing was minimal or absent, there was no expectation of a finished room below grade, and the wall was never intended to be part of a conditioned space. The newer stock was built assuming the opposite. Those two need different work, and the mistake that costs the most is treating an older wall like a newer one and putting a finished room against it without dealing with water first.
Water is settled before anything else, and here that is not a formality
On the older half of this stock the wall gets its water in spring, from ground that has been frozen and is now releasing, and it arrives through the joint between the wall and the footing rather than through the wall itself. That is a drainage question and it is answered before any insulation is priced. Foam over a wall that is still taking water in April seals the problem in rather than solving it, and on a basement that somebody intends to finish it is the most expensive possible order of work.
What is already against the wall, and whether it comes off
Where an older Stony Plain basement has been finished once already, what is behind the panelling is usually a stud wall standing off bare concrete with batt between the studs and a poly sheet stapled over it. That assembly puts a vapour barrier on the warm side of a cold surface and traps whatever condenses there. It generally has to come out. That is a real cost and it is the line that most often separates two quotes on the same house, so it belongs in the conversation before a number rather than after one.
What has to cover the foam once the room is used
Where a Stony Plain basement is going to be a living space, the foam has to be covered by a thermal barrier, and in practice that means the framing and boarding that follow. It is worth settling at the start because a basement insulated for storage and one insulated as a family room are different scopes, and opening the same wall twice is the outcome nobody wants.

Basement Spray Foam Insulation Stony Plain: Common Questions
Why does it only get damp in spring? That is the older stock here, and it is drainage rather than insulation. It comes first.
Does the existing stud wall have to come out? On an older basement usually yes, and it is the biggest single variable in the price.
Does a basement used only for storage need insulating? Then say so before pricing. It is a different scope from a room somebody will live in.
