Crawl space spray foam insulation in Chestermere is unusual work, because most houses here do not have one. The subdivisions built since 2000 have full basements. The crawl spaces are almost all on the original lakeside properties and the acreages, and those are a completely different kind of building.
The summer village came first, and it is still there
Before this was a city it was a summer village of seasonal cottages around the water, and a good number of those buildings are still standing and are now lived in year round. They were built on shallow foundations or piers for a building nobody intended to occupy in January, and what sits under them was never meant to be part of a heated house. Winterising one of these is the single most common crawl space job in Chestermere, and it starts with finding out what the foundation actually is rather than assuming.
What a converted seasonal building arrives with
The recurring list is short and predictable: an open or partly open perimeter, a bare earth floor, no ground cover of any kind, plumbing added later and run wherever there was room, and insulation stuffed between the floor joists at some point by somebody. That last item is the one to be clear about, because insulation between the joists with cold air still moving underneath it does very little and holds moisture against the floor structure while it does it.
The ground cover goes down before anything else
Bare earth in a closed crawl space releases moisture continuously, and sealing the perimeter without dealing with that turns a draughty space into a damp one. A sealed ground barrier comes first, then the perimeter walls, and then the space is part of the house rather than outside it. Doing those in the wrong order is the most common way this job goes wrong, and it is worth insisting on the sequence even when only part of the budget is available.
Freeze risk under a building that was never heated below
Pipes running through a crawl space that was open to the air are one hard winter from a repair that costs more than the insulation. On a converted Chestermere cottage those runs are frequently improvised and close to the perimeter, so establishing where they are is part of the visit rather than an afterthought. In several of these buildings the freeze risk, not the comfort, is the reason to do the work at all.
Crawl Space Spray Foam Insulation Chestermere: Common Questions
Our place was a summer cottage. Can it be made year-round? Usually yes, and the crawl space is where it starts. What is under the building decides the approach.
There is insulation between the floor joists already. Is that enough? Rarely. With cold air still moving below it, it does little and can hold moisture against the floor.
Do we need a ground cover if we are sealing it? Yes, and it goes first. Sealing a space with bare earth in it trades a cold crawl space for a damp one.
What goes over the foam once it is sprayed? In a Chestermere crawl space that counts as a service space, an ignition barrier is normally what is required, and a thermal barrier where the space is finished.
