Wall spray foam insulation in Grande Cache runs into a limit that was set when the townsite was framed. About 75% of homes here were built before 1991, and because they went up in phases to a small number of designs, the wall you have is the wall your whole street has: a known stud depth, a known sheathing, a known cladding. Whatever product goes into that cavity, its total R-value is capped by how deep the cavity is, and no decision made today changes that.
What the cavity depth means in practice
A shallower wall than a modern build holds less of anything. Closed-cell foam at roughly R-6 to R-7 per inch gets more out of a given depth than fibre does, which is the whole reason it is worth considering in a shallow cavity, but it does not create depth that is not there. An honest wall quote on this stock says what the cavity is, what the filled value will be, and where the remaining loss is going to be. A quote that promises a modern wall value from an older wall is describing a different building.
The air seal is the part that changes how the house feels
What an owner notices after wall work is usually not the R-value, it is the end of the draught along the floor and the end of the cold inside corner. Those are air leakage effects, through the sheathing joints, around the window rough openings, at the top and bottom plates and at the junction with the band joist. Foam closes those as it fills, which is why it changes the feel of a room more than its numeric improvement suggests.
The wall has to be open, and that dictates the timing
There is no satisfactory way to get foam into a closed wall cavity. It goes in when the interior finish is off or the cladding is off, which means wall work is almost always part of something else: a renovation, a window replacement, a re-side, or fixing damage. The practical advice on this stock is therefore to decide now what you would do if the wall were open, so that when it is open for another reason the decision is already made and the opportunity is not lost.
From outside, when the siding is coming off
If the cladding is being replaced, there is a better version of this job available: insulate on the outside of the sheathing as a continuous layer, which covers the studs rather than sitting between them, and bridges the framing instead of leaving it exposed. On a repeating townsite plan, where every house on a run has the same elevation and the same trim, this is also the version that can be planned and priced for several houses at once.
One elevation is sometimes the whole job
Not every wall in a house deserves the same treatment. The elevation that takes the weather in this valley, or the one behind a room that is always cold, is frequently the only one worth opening. Doing one wall properly, including the band joist below it and the top plate above it, is a better purchase than doing four walls partially, and it is a far easier job to fit into a single visit.

Wall Spray Foam Insulation Grande Cache: Common Questions
Can you fill our walls without taking anything apart? Not with foam. It needs the cavity open, from inside or outside, which is why wall work usually travels with a renovation or a re-side.
Is it worth it in a shallow older wall? Often, because closed-cell gets more value out of the depth available and seals the cavity at the same time. The cap set by the cavity depth stays, and should be stated plainly in the quote.
Should we do all four walls? Rarely. One exposed elevation, done properly with the band joist and the top plate, usually buys more comfort than a partial job all round.
How much does wall spray foam insulation cost in Grande Cache? Priced by the board foot over the cavity area at the depth it will take, so the wall's area and the stud depth set the material. Opening up and restoring the finish is usually the larger part of the project.
