Crawl space spray foam insulation in Fort Saskatchewan is nearly all work in the oldest part of town. This is a settlement with real age to it, and a number of the houses on the original streets were built before a full basement was standard practice, so what is under them is a shallow void that was never meant to be part of a heated house.
Houses that predate the full basement
On those properties the crawl space is not a design choice, it is what was normal when the house went up. It is typically shallow, of stone, block or early concrete, sometimes with a floor that is partly earth and partly a later slab poured in one section. That variety is the reason nothing gets quoted from a description. Somebody has to get under the building and see what is actually there, because the answer changes both the method and the cost by a wide margin.
What a century of small repairs leaves behind
These voids accumulate history. Plumbing has been rerouted more than once, an old coal or oil line may still be in place, a duct has been added, and insulation of two or three eras is jammed between the joists in different states of collapse. Some of it holds moisture against the floor structure above it, which is a slow problem rather than a dramatic one and is usually well advanced before an owner notices anything.
Sealed and brought inside, with the ground covered first
The old approach was to vent a crawl space year round. In this climate that brings cold air in for five months and humid air in for three, which is the opposite of useful. The current approach is to seal the perimeter and bring the space inside the building envelope, and that begins with a sealed barrier over any exposed ground. Closing up a space with bare earth in it without covering it turns a cold crawl space into a damp one, and the order matters more than the product.
Freeze risk on a small old house
Water lines in a Fort Saskatchewan crawl space of this age are frequently run along the perimeter where there was room, which puts them in the coldest part of a void that is open to the air. In a winter with no thaw in it that is a genuine risk, and on several of these houses the freeze exposure rather than the cold floor is the reason the work is worth doing.
Crawl Space Spray Foam Insulation Fort Saskatchewan: Common Questions
Our house is one of the old ones. Can this be done? Yes, and it is common work here. What is under the building gets established first, because these vary enormously.
Is insulation between the joists already enough? With cold air moving below it, it does little, and where it is against a damp floor structure it can do harm.
Do the vents stay open? No. The space is sealed and brought inside the envelope, starting with a barrier over the ground.
Does an unfinished crawl space still need it? Frequently yes. Even an unfinished Fort Saskatchewan crawl space needs an ignition barrier or thermal barrier if it is accessible, and that gets confirmed on site.
