Spray foam insulation cost in Devon comes down to a unit and a set of local variables. The unit is the board foot — one square foot sprayed one inch thick — so the quantity on any job is simply area multiplied by target thickness. That part is arithmetic and you can do it yourself. What you cannot do from a desk is the second part: the conditions in a particular Devon building that make the same quantity of foam take two hours or six.
Which foam, because it changes the rate not the quantity
Closed-cell is the denser material, roughly R-6 to R-7 per inch, and it becomes its own vapour barrier at about two inches. Open-cell is roughly R-3.5 to R-3.8 per inch, softer and cheaper per board foot. For the same target R-value you need roughly twice the thickness in open-cell, so comparing two quotes means checking which product and what thickness each one assumed. Two numbers that look far apart are often the same job specified differently.
The Devon variables, in rough order of how much they move it
Attic access. The original townsite roofs have shallow heels and low pitch, so the working space narrows to almost nothing at the perimeter — which is exactly where the work needs doing. That is slow, awkward labour, and it is the biggest single difference between a Devon attic and a newer walk-up attic of the same square footage.
Whether anything has to come out. A basement finished decades ago with a stud wall, batt and poly against the foundation has to be opened before the wall can be sprayed. Removal, disposal and rebuilding are frequently a larger share of the total than the foam itself, and an owner is entitled to see that split out rather than buried.
Foundation type. Block foundations need the foam carried onto the top course and across the sill bearing to close off the hollow cores, which is extra area and extra care compared with a flat poured wall.
Preparation and protection. A spray operation needs the area masked, ventilated and vacated for a period. In an occupied house that is scheduling and masking labour. In an empty building being renovated it is close to nothing.
Travel and setup. Devon is a short run from the Edmonton corridor, but a shop or barn on a Leduc County acreage is not, and a single mobilisation to a rural site is why it almost always pays to do several buildings or several jobs in one visit.
What makes a quote comparable
A quote worth comparing states the product, the thickness, the square footage of each area, what is being removed, and what thermal barrier is included. One that gives a single figure for "insulate the basement" cannot be checked against anything.
The smallest useful job in this town
On the pre-1991 stock it is the rim joist. It is the smallest sprayed area in the house, it needs no demolition, and it sits at the top of the coldest wall. If the budget only covers one item, that is the one that returns the most comfort per board foot.

Spray Foam Insulation Cost Devon: Common Questions
Why will nobody give a price over the phone? Because the quantity is area times thickness and the labour depends on access and removals. Neither is visible from a phone call, and a number given without them would be wrong.
Is open-cell the cheaper choice? Per board foot, yes. For the same R-value you need about twice the thickness, so the saving is smaller than it looks — and in a basement or crawl space it is the wrong material regardless.
Does the age of the house change the cost? On a Devon house it changes the labour. Shallow attics and removals of old finishes are where the time goes, not in the spraying.
How much does spray foam insulation cost in Devon? The unit is the board foot and the drivers are access, removals, foundation type and travel. We quote from the building, which is the only way the number means anything.
Who gives free estimates in Devon? We do, in town and out on the county acreages, and we itemise it so you can compare it with anyone else's.
