Spray foam insulation in Morinville is two different conversations rather than one, because this is the most evenly divided town on this site: about 47% of the homes predate 1991 and the rest do not, and the two halves are not mixed together street by street.
An older centre with a ring of newer building around it
The split here is geographic rather than scattered. There is an older core where the houses went up over several decades and were built to the standards of their time, and there is newer building around it that went up under codes which already asked for a sealed envelope. Two houses a few minutes apart can need close to opposite advice, which is why a general recommendation about the town is worth very little and why the first question on any Morinville enquiry is where the house actually is.
Discovery on one side, verification on the other
On the older half the work starts by finding out what is there, because nothing can be assumed: the insulation, the wiring, the additions and the previous repairs are all unknown until somebody looks. On the newer half the assembly is known from the drawings and the question is different, which is whether what was specified was actually achieved on site. Those are two different visits, they take different amounts of time, and they produce very different lists.
The newer half is not the finished half
It would be convenient if a house built to a modern standard had nothing worth doing, and that is not what these buildings show. The design was sound and the execution varies: a seal that stops at a corner, a service drilled through after the inspection, a garage wall that was never completed behind the drywall. Those are workmanship items rather than design ones, they are small, and they are worth finding precisely because everything around them is good enough that one gap does the visible damage.
What is on both lists regardless of which half you are on
The junction between the foundation and the framing is the one item that appears on every house in this town, old or new. On an older Morinville house it is an unsealed cavity nobody has ever reached. On a newer one it is usually insulated and often not sealed, which produces the same symptom for a different reason. It is the cheapest item on either list and it is the one worth doing first in both cases.
Spray Foam Insulation Morinville: Common Questions
Is there anything to insulate in a newer house? Usually yes, and it is workmanship rather than design. Small gaps in an otherwise good envelope.
How do we know which list we are on? The build date, and it is decided at the first visit rather than assumed from the street.
What is worth doing on both? The rim joist. It appears on every house here for one reason or the other.
