About 35% of homes in Stony Plain were built before 1991, which makes this a genuinely mixed town rather than a new one, and it is the reason advice written for this part of the region is wrong for roughly a third of the houses in it.
A town that treats the outside of a building as public
Decades of painting murals across the downtown walls of Stony Plain have left this town with an attitude to exteriors that shows up in the work. The frontages people can see are not surfaces anybody is going to strip, re-clad or insulate from outside, and that is the right answer rather than an obstacle. The consequence is practical: on those buildings the envelope is worked on from the inside, which a sprayed layer suits because it will follow an irregular masonry or plank face that nothing rigid will sit flat against.
Three eras of house, and they fail in different places
The oldest houses here have low attics, foundations built before anybody expected a room below grade, and a ceiling plane that every trade has cut through. The seventies and eighties stock has specified depth over a plane nobody sealed. The newest has trusses, a known assembly, and its losses at the junctions. Those are three different lists and the build year decides which applies, which is why it is the first question rather than the symptom.
Additions are what makes the older half of this town distinctive
Houses on the older streets grew. A porch became a room, a room became a kitchen, a garage got attached, and each of those was built on its own foundation to whatever standard applied that decade. Every junction between an original building and something added to it is a path from outside to inside, and on a house with two additions there are more of those junctions than most owners realise. It is where the money goes on this stock, and it is not the wall.
What is worth doing and what is worth refusing
Some popular purchases do very little here. Drilling and filling a cavity that is either obstructed or already full is one. Adding depth to an attic over a plane full of unsealed penetrations is another. What consistently returns more is the rim joist, the junctions where additions meet, the ceiling plane at its holes, and on the newer stock whatever shares a surface with the garage.

Spray Foam Insulation Stony Plain: Common Questions
Does an older house need a different insulation list? A third of the stock here is, and it needs a different list. The build year settles it.
Can our shopfront be done from outside? No, and it should not be. Work on those buildings goes on the inside face.
Where does the money go furthest? On the older Stony Plain stock, the junctions where the additions meet the original house.
